MARINE VESSEL

Description

FIELD

The present disclosure relates to marine vessels. More particularly, the present disclosure relates to a platform service vessel equipped with service equipment.

BACKGROUND

Marine vessel designs often necessitate trade-offs between functionality and transportability. Vessels that prioritize transportability are typically compact and lightweight, enabling easy overland transport, but such designs often lack the specialized equipment necessary for construction, maintenance, and repair tasks. As a result, these vessels may require on-site set-up, which can be time-consuming and resource intensive. On the other hand, some vessel designs are provided with heavy machinery and equipment to facilitate a broader range of operational tasks. Such vessels, however, either remain in the water, limiting their mobility, or require the use of multiple trucks to transport, leading to increased logistical complexities and costs. The need to reconcile these conflicting design priorities underscores the importance of innovative marine vessel designs that can effectively integrate both transportability and functionality.

Accordingly, there is demand for a marine vessel capable of providing equipment useful for performing a broad range of operational tasks while facilitating overland transport.

DETAILED DESCRIPTION

As described herein, traditional approaches to marine service operations often involve complex and resource-intensive processes. As an example, conventionally, service operations such as dock construction, pile driving, shoreline repair, on-water service and rescue, and the like often necessitate the use of sectional barge units. These units are brought in on large trucks and lifted into the water using a land-based crane. Subsequently, the individual sectional units are then assembled to form a large floating platform. In the case that a crane is necessary to perform the service operations, the land-based crane would be needed to lift another secondary crane onto the completed platform. This preparation process requires careful engineering to consider specific job requirements such as platform capacity and stability, crane size, crane-to-platform connection, and the like. Once assembled, the floating platform would be towed to the worksite and suitably anchored or moored. This process may take several days (or weeks for larger-scale operations) and incur substantial costs on behalf of service operators.

In an effort to circumvent these challenges, some marine vessel manufacturers have taken to producing small platform work boats, but such vessels are too small to accommodate larger equipment such as cranes. Additionally, the limited cargo space of such smaller vessels means that service operators are still often required to bring multiple modified work platforms to the worksite to facilitate task completion.

Accordingly, aspects of the present disclosure relate to providing a marine vessel for alleviating these challenges. In embodiments, a central buoyant hull section of the marine vessel may be provided with service equipment, such as a boom crane, to facilitate construction, maintenance, and repair tasks. The boom (also referred to as a boom arm herein) of the boom crane may include a coupler mechanism configured to interchangeably couple with one or more attachable implements. In embodiments, the marine vessel may include foldable auxiliary buoyant hull sections. The auxiliary buoyant hull sections may be configurable in a stowed hull position to facilitate overland transport, and hydraulically actuated to a deployed hull position after deployment on the water. In the deployed hull position, the auxiliary buoyant hull sections may be adjacent with the central buoyant hull section to extend an effective deck area of the central buoyant hull section. In the stowed hull position, the auxiliary buoyant hull sections may fold so as to provide a space therebetween for the service equipment.

According to the embodiments of the present disclosure, it is possible to provide a marine vessel capable of providing equipment useful for performing a broad range of operational tasks while facilitating overland transport.

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that no limitation of the scope of the disclosure is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the disclosure as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the disclosure.

Before the structures, systems and associated methods relating to the folding marine vessel are disclosed and described, it is to be understood that this disclosure is not limited to the particular configurations, process steps, and materials disclosed herein, and may be suitably modified. It is also to be understood that the terminology employed herein is used for the purpose of describing particular embodiments only and is not intended to be limiting since the scope of the disclosure will be limited only by the claims and equivalents thereof. Additionally, it should be noted in the following description that the same reference numerals in different embodiments denote the same or similar features.

Turning now to the figures, FIGS. 1-7 illustrate different views of a marine vessel 1 according to the embodiments of the present disclosure. Herein, for convenience of description, elements present in multiple views will be collectively described with reference to the figures.

With regard to directions, herein, aspects of the marine vessel will be described with reference to standard nautical directions, such that the rear of the marine vessel 1 in which propulsion and steering systems are provided is referred to as the stern, the front of the marine vessel 1 opposite the stern is referred to as the bow, the left side of the marine vessel 1 when facing forward from the bow is referred to as port, and the right side of the marine vessel 1 when facing forward from the bow is referred to as starboard. Further, as illustrated in FIGS. 1-2, a direction parallel to the longitudinal axis L1 extending between the bow and stern through the center of the marine vessel 1 is referred to as the longitudinal direction, a direction perpendicular to the longitudinal direction (and the vertical direction described below) extending between the starboard side and the port side of the marine vessel 1 is referred to as the transverse direction, and a direction perpendicular to the longitudinal direction and the transverse direction (e.g., perpendicular to a top surface of the marine vessel 1) is referred to as the vertical direction.

As illustrated in FIGS. 1-7, a marine vessel 1 according to the embodiments of the present disclosure primarily includes a central buoyant hull section 10, a set of auxiliary buoyant hull sections 15A, 15B coupled to the central buoyant hull section 10, and service equipment 20 operably connected to the central buoyant hull section 10. The central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A, 15B may also be collectively referred to as a set of buoyant hull sections herein.

The central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A, 15B may respectively include a top surface facing upward in the vertical direction, a bottom surface opposing the top surface, a bow side surface substantially perpendicular to the top and bottom surfaces on the bow side of the marine vessel 1, a stern side surface substantially perpendicular to the top and bottom surfaces on the stern side of the marine vessel 1, a port side surface substantially perpendicular to the top and bottom surfaces on the port side of the marine vessel 1, and a starboard side surface substantially perpendicular to the top and bottom surfaces on the starboard side of the marine vessel 1. The top surface, bottom surface, bow side surface, stern side surface, port side surface, and starboard side surface of the central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A, 15B may be connected together and structured substantially in the shape of a rectangular prism. The top surfaces of the central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A may be substantially flat to create an area for cargo storage.

The central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A, 15B may constructed from a variety of materials including steel, aluminum, fiberglass, or a combination thereof. The materials used for the central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A, 15B are not particularly limited herein, and may be suitably selected in consideration of the desired buoyancy, strength, durability, and weight of the marine vessel 1, for instance.

As illustrated in FIGS. 1, 3-5 and 7, the set of auxiliary buoyant hull sections 15A, 15B may be rotatably coupled to the central buoyant hull section 10 along axes parallel to the central longitudinal axis L1 of the central buoyant hull section 10 by a first set of hinges 18A, 18B. The first set of hinges 18A, 18B may allow for the set of auxiliary buoyant hull sections 15A, 15B to rotate between a deployed hull position, shown in FIGS. 1, 4-7, and a stowed hull position, shown in FIGS. 2-3. In the deployed hull position, the set of auxiliary buoyant hull sections 15A, 15B are rotated by the first set of hinges 18A, 18B to be adjacent and substantially parallel to the central buoyant hull section 10 along the port and starboard sides of the marine vessel 1, respectively, such that the top surfaces of the set of auxiliary buoyant hull sections 15A, 15B and the top surface of the central buoyant hull section 10 are oriented upward in the vertical direction. In the stowed hull position, the set of auxiliary buoyant hull sections 15A, 15B are rotated by the first set of hinges 18A, 18B to be located substantially above the top surface of the central buoyant hull section 10 in the vertical direction, such that the top surfaces of the set of auxiliary buoyant hull sections 15A, 15B are oriented downward in the vertical direction to obliquely face the top surface of the central buoyant hull section 10. In general, the operation of rotating the set of auxiliary buoyant hull sections 15A, 15B around the first set of hinges 18A, 18B between the deployed hull position and the stowed hull position is referred to “folding” herein. As a detailed description of the folding operation will be provided later, it will be omitted here.

It should be noted that here, although an example is shown in the figures in which two auxiliary buoyant hull sections 15A, 15B are coupled to the central buoyant hull section 10, the present disclosure is not limited thereto, and configurations with one, or three or more auxiliary buoyant hull sections 15A, 15B are also within the scope of this disclosure. As an example, in certain embodiments, two auxiliary buoyant hull sections may be coupled to the port and starboard sides of the central buoyant hull section for a total of four auxiliary buoyant hull sections. In such a configuration, the two auxiliary buoyant hull sections on each of the port and starboard sides may be separated from each other in the longitudinal direction to create a space therebetween for accommodating the service equipment 20 when configured in the stowed hull position.

As best seen in FIGS. 1 and 4, the movement of the first set of hinges 18A, 18B may be controlled by a mechanical actuator 19. In embodiments, the mechanical actuator 19 may control movement of the first set of hinges 18A, 18B using a hydraulic, pneumatic, electric, or manual system, but the mechanical actuator is not particularly limited herein, and any suitable actuation system for the first set of hinges 18A, 18B capable of achieving movement of the set of auxiliary buoyant hull sections 15A, 15B between the deployed hull position and the stowed hull position may be used. In embodiments, the first set of hinges 18A, 18B may be configured to satisfy a predetermined hinge capacity threshold. Here, the hinge capacity threshold refers to a specific criterion or boundary value used to determine whether the first set of hinges 18A, 18B achieve a desired level of strength. In embodiments, the hinge capacity threshold may be set based on the buoyant force exerted by a fluid such as water on the set of auxiliary buoyant hull sections 15A, 15B. In this way, by configuring the first set of hinges 18A, 18B to satisfy a hinge capacity threshold set based on the buoyant force exerted by a fluid such as water on the set of auxiliary buoyant hull sections 15A, 15B, the first set of hinges 18A, 18B are able to maintain the set of auxiliary buoyant hull sections 15A, 15B in the deployed hull position without additional reinforcement (e.g., the first set of hinges 18A, 18B have sufficient strength to tolerate the buoyant force of the water).

As illustrated in FIGS. 1-7, the service equipment 20 may be operably connected to a portion of the top surface of the central buoyant hull section 10. The service equipment 20 may be disposed on the top surface of the central buoyant hull section 10 in a suitable location to facilitate performance of a range of service operations (e.g., dock construction, pile driving, shoreline repair, on-water service and rescue). The service equipment 20 may be supported by buoyant forces applied to the central buoyant hull section 10 when the marine vessel is deployed on water. That is, the central buoyant hull section 10 and the service equipment 20 provided thereon may float on the water in a stable arrangement for facilitating operation of the service equipment 20. Further, as described later herein, the service equipment 20 may be disposed on the top surface of the central buoyant hull section 10 to at least partially occupy a gap formed between the first auxiliary buoyant hull section 15A and a second auxiliary buoyant hull section 15B at the closest point therebetween. Put differently, the service equipment 20 may extend or protrude through the space separating the first auxiliary buoyant hull section 15A and the second auxiliary buoyant hull section 15B, such that the first auxiliary buoyant hull section 15A and the second auxiliary buoyant hull section 15B do not come into contact with one another when in the stowed hull position.

In embodiments, the service equipment 20 may be integrally formed with the central buoyant hull section 10 of the marine vessel 1. Here, the term “integrally formed” refers to a configuration in which the service equipment 20 and the central buoyant hull section 10 are constructed as a single, unified structure rather than being separate components subsequently assembled. In this way, the service equipment 20 constitutes a permanent part of the marine vessel 1, providing enhanced structural integrity, stability, and durability when performing service operations. The integration of the service equipment 20 into the central buoyant hull section 10 can be achieved during the manufacturing of the marine vessel 1, where supporting framework for the service equipment 20 is incorporated directly into the design of the central buoyant hull section 10, such as by being welded, molded, or cast as a continuous and unbroken part of the structure of the central buoyant hull section 10. This integral formation reduces points of mechanical failure between the service equipment 20 and the central buoyant hull section 10 and provides a more robust connection capable of withstanding the dynamic forces imposed during service equipment 20 operation in marine environments. As a result, it is possible to reduce the need for additional mounting or hardware attachment and increase the operability of the marine vessel 1.

FIG. 8 illustrates an example of a coupler mechanism 20b for a boom crane provided on the marine vessel 1, according to the embodiments of the present disclosure. In embodiments, with reference to FIG. 8, the service equipment 20 may include a boom crane having a retractable boom arm 20a. The boom arm 20a may be telescopic and capable of extending to facilitate performance of a range of service operations, and retract for storage. In embodiments, the boom arm 20a may be a knuckle boom arm (also known as an articulating boom) equipped with multiple sections connected at joints (e.g., knuckles) to facilitate greater flexibility of operation. In embodiments, a distal end of the boom arm 20a may be integrally provided (e.g., formed as a single, unified structure) with a coupler mechanism 20b configured to interchangeably couple with an attachable implement 20c. For instance, as illustrated in FIG. 8, the coupler mechanism 20b attached to the boom arm 20a may be configured to interchangeably couple with attachable implements 20c such as a bucket attachment (e.g., excavator bucket), basket attachment (e.g., personnel basket), fork attachment, jib, or the like.

In embodiments, the coupler mechanism 20b is configurable between a first coupler operational mode and a second coupler operational mode. In the first coupler operational mode, the coupler mechanism 20b may be configurable for rotational and/or translational motion about one or more axes defined relative to the axes of the boom arm 20a. For example, an attachable implement 20c such as a bucket attachment or a fork attachment may rotate to an angled position relative to the distal end of the boom arm 20a, or an attachable implement 20c such as a basket attachment may be translated to a shifted position relative to the distal end of the boom arm 20a. In this way, the coupler mechanism 20b may facilitate a full range of motion of the coupled attachable implement 20c. In the second coupler operational mode, the coupler mechanism may remain rigidly coupled to the boom arm 20a with no rotation and/or translation. In this way, the coupler mechanism 20b may provide a configuration that facilitates a simple coupling arrangement associated with reduced costs, number of parts, and points of failure. It should be noted that herein, although an example embodiment is illustrated in which the service equipment 20 is a boom crane including the boom arm 20a, the present disclosure is not limited hereto, and a variety of types of service equipment 20 may be provided on the central buoyant hull section 10.

In embodiments, in the case that the service equipment 20 is a boom crane, the boom crane may include a crane winch cable 20d. The crane winch cable 20d may be routed either internally or externally along the boom arm 20a and exit from the distal end of the boom arm 20a. The crane winch cable 20d may be provided such that operation of the coupler mechanism 20b is not impeded. In embodiments, the crane winch cable 20d may be configurable between a first winch operational mode in which the crane winch cable 20d is used in combination with the coupler mechanism 20b and a second winch operational mode in which the crane winch cable 20d and the coupler mechanism 20b are used independently.

More particularly, the crane winch cable 20d may include a steel wire, synthetic rope, or other cable that runs over a system of pulleys (sheaves) attached to the boom arm 20a of the boom crane. The crane winch cable 20d may be wound onto a winch drum, which may be driven by a motor. The crane winch cable 20d may be used to facilitate movement of a load attached to the boom crane. For instance, the crane winch cable 20d may be wound or unwound from the winch drum to adjust the length of the crane winch cable 20d and the vertical position of an attached load. In the first winch operational mode in which the crane winch cable 20d is used in combination with the coupler mechanism 20b, the crane winch cable 20d may be used together with one or more attachable implements 20c to provide additional management or support of a load handled by the attachable implement 20c. In the case that the attachable implements 20c is a pallet fork or a bucket, the crane winch cable 20d may be separately attached to the load being lifted by the pallet fork or bucket to provide additional stability and safety and enable easy loading and unloading of materials. In the second winch operational mode in which the crane winch cable 20d and the coupler mechanism 20b are used independently, either one of the crane winch cable 20d or the coupler mechanism 20b may be used to independently support operation of the attachable implements 20c. Such a configuration may be suitable for simple operations, facilitating increased operation flexibility.

FIG. 9 illustrates an example structural configuration of the coupler mechanism 20b for a boom crane provided on a marine vessel, according to the embodiments of the present disclosure. In embodiments, the coupler mechanism 20b may include an ISO 24410 quick-attach coupler. As illustrated in FIG. 9, the coupler mechanism 20b may include an attachment mounting frame 41, a quick coupler 42, a gap 43 between the attachment mounting frame 41 and the quick coupler 42, three zone of interface contact surfaces 44 where the attachment mounting frame 41 contacts the quick coupler 42, and a wedge/pin contact surface 45 where a wedge or pin of the quick coupler 42 contacts the attachment mounting frame 41. The dimensions of the quick coupler 42 may be such that the interface of the vertical face of the quick coupler 42 and the attachment mounting frame 41 does not result in surface-to-surface contact when engaged and locked together. This connection may result in contact in each of the three zones of interface contact surfaces 44 between the quick coupler 42 and the attachment mounting frame 41 during operation. By providing the boom arm 20a with a coupler mechanism 20b such as an ISO 24410 quick-attach coupler, it becomes possible to facilitate efficient and rapid switching between tools, enabling the crane to be adapted to different service operations without the need for significant downtime or complex modifications.

Aspects of the present disclosure relate to the recognition that in order to accommodate a boom crane having a coupler mechanism on the marine vessel 1, it may be desirable to make structural modifications to the marine vessel 1 to facilitate stability. For instance, it may be desirable to provide reinforcing members around the base of the crane and mounting platform to handle the varying loads and dynamic stresses imparted by the different attachable implements and the forces of the marine environment, including wind, waves, and vessel movement. Additionally, it may be desirable to fortify the central buoyant hull section near the crane with additional structural supports to ensure stability during operation. These modifications facilitate the balance and operational safety of the marine vessel while using the crane in various configurations, allowing the crane to function effectively and securely with a range of attachable implements.

As illustrated in FIGS. 1-7, the marine vessel 1 may include a set of rest frame structures 22A, 22B disposed at predetermined locations straddling the central longitudinal axis of the marine vessel 1. The rest frame structures refer to structures for supporting a portion of the service equipment 20 as well as the set of auxiliary buoyant hull sections 15A, 15B. More particularly, as illustrated in FIG. 3 with respect to rest frame structure 22B, rest frame structure 22B may include a first support section 22B1 configured to support a portion of the service equipment 20, and a set of second support sections 22B2A, 22B2B to support the set of auxiliary buoyant hull sections 15A, 15B when configured in the stowed hull position. In the case that the service equipment 20 is implemented using a boom crane as described as an example herein, the boom of the boom crane may rest on the first support section 22B1 when in a retracted state, the first auxiliary buoyant hull section 15A may rest on the second support section 22B2A, and the second auxiliary buoyant hull section 15B may rest on the second support section 22B2B. In this way, the set of rest frame structures 22A, 22B may assist in bearing the weight of the service equipment 20 and the set of auxiliary buoyant hull sections 15A, 15B, reducing the load on the first set of hinges 18A, 18B and facilitating stability of the marine vessel 1 during movement and transportation.

As described herein, the set of auxiliary buoyant hull sections 15A, 15B may be configured to rotate between a deployed hull position and a stowed hull position, shown in FIGS. 2-3. In the deployed hull position, as illustrated in FIGS. 1, 4-7, the set of auxiliary buoyant hull sections 15A, 15B may be rotated by the first set of hinges 18A, 18B to be adjacent and substantially parallel to the central buoyant hull section 10 along the port and starboard sides of the marine vessel 1, respectively. In the deployed hull position, a height difference between the top surfaces of the set of auxiliary buoyant hull sections 15A, 15B and the top surface of the central buoyant hull section 10 in the vertical direction may be less than or equal to a predetermined height distance threshold. The predetermined height distance threshold may be suitably determined by a manufacturer of the marine vessel, and may, for example, be between 1 and 3 inches. In certain embodiments, the predetermined height distance threshold may be 2 inches. In other embodiments, in the deployed hull position, the top surfaces of the set of auxiliary buoyant hull sections 15A, 15B may be coplanar (e.g., substantially level) with the top surface of the central buoyant hull section 10. Additionally, in the deployed hull position, the set of auxiliary buoyant hull sections 15A, 15B may function as pontoons, stabilizing the marine vessel 1 on the water, providing additional buoyancy to allow for greater transportable cargo weight, and distributing the weight of the marine vessel 1 over a larger area to maintain a shallow draft. In this way, by configuring the set of auxiliary buoyant hull sections 15A, 15B in the deployed hull position after launching the marine vessel 1 onto the water, it is possible to facilitate stable floatation and movement of the marine vessel 1.

Additionally, in embodiments, a set of floor panels 16A, 16B (illustrated by the dotted lines in FIGS. 1, 4, 5, and 7) may be disposed between the top surface of the central buoyant hull section and the top surfaces of the set of auxiliary buoyant hull sections 15A, 15B to cover the space between the central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A, 15B when the set of auxiliary buoyant hull sections 15A, 15B are configured in the deployed hull position. In embodiments, the set of floor panels 16A, 16B may be formed from steel or other suitable material, and be integrally formed with the top surfaces of the auxiliary buoyant hull sections 15A, 15B so as to fold together with the auxiliary buoyant hull sections 15A, 15B when converting between the deployed hull position and the stowed hull position. In certain embodiments, the set of floor panels 16A, 16B may be separately mountable, and put in place by an operator of the marine vessel 1 after the marine vessel 1 has been deployed in the water. For instance, in embodiments, the set of floor panels 16A, 16B may slot into grooves provided on the top surfaces of the set of auxiliary buoyant hull sections 15A, 15B and the central buoyant hull section or be otherwise fastened thereto using clamps, latches or the like. The number of the set of floor panels 16A, 16B is not particularly limited, and may be provided in a number, size, and shape in consideration of the dimensions of the marine vessel 1. As an example, the set of floor panels may include six floor panels, such that three floor panels may be mounted on both the port and starboard sides of the marine vessel 1.

Providing the set of floor panels 16A, 16B may be used to form a substantially level, continuous surface between the central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A, 15B that extends an effective deck area of the central buoyant hull section 10. That is, the top surfaces of the set of auxiliary buoyant hull sections 15A, 15B and the set of floor panels 16A, 16B provide area for crew members to perform tasks and for additional cargo to be stored. In this way, by using the set of floor panels 16A, 16B to create a level, continuous surface between the central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A, 15B, it becomes possible not only to provide a larger area for storing cargo, but also to allow crew members to use the additional surface area to facilitate service operations.

Consider, for instance, an example in which the marine vessel 1 is used for a pile-driving task as part of a dock construction operation. The marine vessel 1 may be positioned such that the set of auxiliary buoyant hull sections 15A, 15B are located directly adjacent to a pile to be driven by a pile-driver provided on the marine vessel 1 (e.g., as the service equipment 20). In such a scenario, operators may stand on the set of auxiliary buoyant hull sections 15A, 15B and the level surface created between the central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A, 15B by the set of floor panels 16A to hold on to and steady the piles while being driven. In this way, operators may achieve close proximity with the pile, and avoid having to stretch out over the water to reach it. Accordingly, the level surface created between the central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A, 15B by the set of floor panels 16A may facilitate both reliable anchoring of the piles as well as operator safety.

In the stowed hull position, as illustrated in FIGS. 2-3, the set of auxiliary buoyant hull sections 15A, 15B may be rotated by the first set of hinges 18A, 18B to be located above the top surface of the central buoyant hull section 10 in the vertical direction. In the stowed hull position, as best viewed in FIG. 3, the top surfaces 15ATS, 15BTS of the set of auxiliary buoyant hull sections 15A, 15B are oriented downward in the vertical direction to obliquely face the top surface 10TS of the central buoyant hull section 10, creating an acute angle between the top surfaces 15ATS, 15BTS of the set of auxiliary buoyant hull sections 15A, 15B and the top surface 10TS of the central buoyant hull section 10.

As illustrated in FIGS. 2-3, in the stowed hull position, a gap 25 is formed along the central longitudinal axis of the central buoyant hull section 10 between the first auxiliary buoyant hull section 15A and the second auxiliary buoyant hull section 15B. As used herein, the gap 25 refers to the space formed between the first auxiliary buoyant hull section 15A and the second auxiliary buoyant hull section 15B at their closest point. In embodiments, in the case that the set of auxiliary buoyant hull sections 15A, 15B have the shape of rectangular prisms and are oriented obliquely with respect to the top surface 10TS of the central buoyant hull section 10, as described herein, the gap 25 may be formed in the shape of an elongated triangular prism extending along the central longitudinal axis of the central buoyant hull section 10 between the first auxiliary buoyant hull section 15A and the second auxiliary buoyant hull section 15B. More particularly, as best viewed in FIG. 3, the gap 25 may be formed between a first edge portion 15AE defined by the top surface 15ATS and a side surface of the first auxiliary buoyant hull section 15A and a second edge portion 15BE defined by the top surface 15BTS and a side surface of the second auxiliary buoyant hull section 15B. By means of the gap 25, the first auxiliary buoyant hull section 15A and the second auxiliary buoyant hull section 15B remain separated from each other at all points by a non-zero, predefined minimum distance d measured between the closest respective points of the first auxiliary buoyant hull section 15A and the second auxiliary buoyant hull section 15B.

Additionally, as illustrated in FIGS. 2-3, in the stowed hull position, a portion of the service equipment 20 may be disposed to at least partially occupy the gap 25 formed between the first auxiliary buoyant hull section 15A and the second auxiliary buoyant hull section 15B in one or more of the vertical, transverse, or longitudinal directions. For instance, in the case that the service equipment 20 is implemented as a boom crane, the boom of the boom crane in a retracted position may be oriented to extend along the gap 25 in the longitudinal direction between the first auxiliary buoyant hull section 15A and the second auxiliary buoyant hull section 15B, thereby separating the first auxiliary buoyant hull section 15A and the second auxiliary buoyant hull section 15B by a distance greater than or equal to the predefined minimum distance d.

Further, in embodiments, in the case that the rest frame structures 22A, 22B described above are provided to support the set of auxiliary buoyant hull sections 15A, 15B and the service equipment 20, as can best be seen in FIG. 3, a volume 27 extending along the central longitudinal axis of the central buoyant hull section 10 is defined by the inner surfaces of the rest frame structures 22A, 22B and the top surface 10TS of the central buoyant hull section 10. Notably, the set of auxiliary buoyant hull sections 15A, 15B do not impinge (e.g., intrude) upon the volume 27 when configured in the stowed hull position. As a result, a space can be created on the top surface 10TS of the central buoyant hull section 10 for accommodating the service equipment 20.

According to the embodiments described herein, by configuring the first set of hinges 18A, 18B and the set of auxiliary buoyant hull sections 15A, 15B to form a gap 25 and a volume 27 along the central longitudinal axis of the central buoyant hull section 10 between the first auxiliary buoyant hull section 15A and the second auxiliary buoyant hull section 15B, it is possible to create space on the central buoyant hull section 10 to accommodate large-scale service equipment 20, such as a boom crane. In this way, the marine vessel 1 can be manufactured to include the service equipment 20 while maintaining a compact form factor in the stowed hull position to facilitate transport.

With regard to dimensions, in embodiments, each auxiliary buoyant hull section 15A, 15B may have a width of 1356 millimeters (53.375 inches), and the central buoyant hull section 10 may have a width of 3277 millimeters (129 inches). Accordingly, a maximum width dimension of the marine vessel 1 in the transverse direction when the set of auxiliary buoyant hull sections 15A, 15B are in the deployed hull position is less than or equal to 7396 millimeters (291.1875 inches) when accommodating for the distance maintained between the set of auxiliary buoyant hull sections 15A, 15B and the central buoyant hull section 10 by the bracing frame assembly (described later herein). A maximum length dimension of the marine vessel 1 in the longitudinal direction may be less than or equal to 12,207 millimeters (480.625 inches), not including the service equipment 20.

Additionally, when the set of auxiliary buoyant hull sections 15A, 15B are in the stowed hull position, the marine vessel 1 is preferably configured to have a maximum width dimension in the transverse direction of less than or equal to 3632 millimeters (143 inches), a maximum height dimension including the service equipment 20 of 3125 millimeters (123 inches) in the vertical direction when not loaded on a transport trailer, and a maximum height dimension including the service equipment 20 of 1039 millimeters (159 inches) in the vertical direction when loaded on a transport trailer. In this way, the marine vessel 1 may be transported on national highways while reducing the need for special permits.

As illustrated in FIGS. 1, 2, 4, 5, and 7 (and best seen in FIG. 2), in embodiments, the marine vessel 1 may be provided with a bracing frame assembly 30 including a set of auxiliary hull frame sections 31A, 31B operably connected to the set of auxiliary buoyant hull sections 15A, 15B and a set of central hull frame sections 32A, 32B operably connected to the central buoyant hull section 10. More particularly, the set of auxiliary hull frame sections 31A, 31B may be rotatably connected to inner side surfaces (e.g., longitudinal side surfaces facing the central buoyant hull section 10) of the set of auxiliary buoyant hull sections 15A, 15B by a second set of hinges 31AH, 31BH, best viewed in FIG. 2. The set of central hull frame sections 32A, 32B may be respectively fixed to port and starboard side surfaces (e.g., longitudinal side surfaces facing outward) of the central buoyant hull section 10. As described in greater detail later herein, the set of auxiliary hull frame sections 31A, 31B may be configured to operably engage with the set of central hull frame sections 32A, 32B, respectively, to secure the set of auxiliary buoyant hull sections 15A, 15B to the central buoyant hull section 10.

In embodiments, the set of auxiliary hull frame sections 31A, 31B may be configured to rotate around the second set of hinges 31AH, 31BH between a deployed frame position and a stowed frame position. In general, the deployed frame position of the set of auxiliary hull frame sections 31A, 31B is preferably used when the set of auxiliary buoyant hull sections 15A, 15B are in the deployed hull position (e.g., when the marine vessel 1 is deployed for use on the water), and the stowed frame position of the set of auxiliary hull frame sections 31A, 31B is preferably used when the set of auxiliary buoyant hull sections 15A, 15B are in the stowed hull position (e.g., when the marine vessel 1 is prepared for transport).

As best viewed in FIG. 2, when the set of auxiliary buoyant hull sections 15A, 15B are configured in the stowed hull position and the set of auxiliary hull frame sections 31A, 31B are configured in the stowed frame position, the set of auxiliary hull frame sections 31A, 31B are located above the set of central hull frame sections 32A, 32B in the vertical direction. The set of auxiliary hull frame sections 31A, 31B may have a cross-brace structure, and be constructed from a suitable material such as steel, aluminum or the like. In embodiments, in the stowed frame position, the set of auxiliary hull frame sections 31A, 31B may freely hang downward from the side surfaces of the set of auxiliary buoyant hull sections 15A, 15B.

When the set of auxiliary buoyant hull sections 15A, 15B are configured in the deployed hull position and the set of auxiliary hull frame sections 31A, 31B are configured in the deployed frame position, the set of auxiliary hull frame sections 31A, 31B may extend perpendicularly from the inner side surfaces of the set of auxiliary buoyant hull sections 15A, 15B to couple with the set of central hull frame sections 32A, 32B. In embodiments, the set of auxiliary hull frame sections 31A, 31B may engage with the set of central hull frame sections 32A, 32B using a latching mechanism, clamps, sliding rails, locking pins or other suitable attachment mechanism. In this way, by coupling the set of auxiliary hull frame sections 31A, 31B on the set of auxiliary buoyant hull sections 15A, 15B with the set of central hull frame sections 32A, 32B on the central buoyant hull section 10, it becomes possible to secure the set of auxiliary buoyant hull sections 15A, 15B to the central buoyant hull section 10.

In embodiments, the set of auxiliary hull frame sections 31A, 31B may be configured to maintain a predetermined distance between the set of auxiliary buoyant hull sections 15A, 15B and the central buoyant hull section 10. As an example, the set of auxiliary hull frame sections 31A, 31B may be configured to maintain a predetermined distance between the set of auxiliary buoyant hull sections 15A, 15B and the central buoyant hull section 10 of 100 to 1000 millimeters (3.9-39.4 inches). By maintaining a predetermined distance between the set of auxiliary buoyant hull sections 15A, 15B and the central buoyant hull section 10, it becomes possible to distribute the weight of the marine vessel 1 over a larger area, and facilitate stability of the marine vessel 1 on the water. It should be noted that the predetermined distance between the set of auxiliary buoyant hull sections 15A, 15B and the central buoyant hull section 10 is not particularly limited herein, and may be configured based on the weight of the marine vessel 1, the type of service equipment 20 provided thereon, and the like. Further, as described herein, a set of floor panels 16A, 16B (illustrated by the dotted lines in FIGS. 1, 4, 5, and 7) may be disposed between the top surface of the central buoyant hull section 10 and the top surfaces of the set of auxiliary buoyant hull sections 15A, 15B to cover the space between the central buoyant hull section 10 and the set of auxiliary buoyant hull sections 15A, 15B when the set of auxiliary buoyant hull sections 15A, 15B are configured in the deployed hull position.

In embodiments, as illustrated in FIGS. 1, 2, 4-6, the set of auxiliary buoyant hull sections 15A, 15B may include a set of through-holes 34A, 34B, 34C, 34D (hereinafter referred to as through-holes 34A-D) passing through the top surfaces and bottom surfaces of the set of auxiliary buoyant hull sections 15A, 15B. The set of through-holes 34A-D may be configured to receive insertion of a set of locking bolts 35A, 35B for securing the set of auxiliary hull frame sections 31A, 31B in the deployed frame position. The set of locking bolts 35A, 35B may include poles, bars, posts, or rods having a thickness configured to pass through the set of through-holes 34A-D. In embodiments, the set of locking bolts 35A, 35B may be configured to operably engage with the set of auxiliary hull frame sections 31A, 31B by means of a clamp, latch, or other locking mechanism for locking the set of auxiliary hull frame sections 31A, 31B in the deployed frame position. It should be noted that here, for convenience of description, a configuration in which two locking bolts 35A, 35B are used was described as an example, but the present disclosure is not limited herein, and a locking bolt may be provided for each through-hole.

In embodiments, as illustrated in FIG. 7, the marine vessel 1 may include a set of buoyant platforms 38A, 38B configured to be coupled to the set of auxiliary buoyant hull sections 15A, 15B via respective bolt pads 39A, 39B provided on a set of side surfaces of the set of auxiliary buoyant hull sections 15A, 15B. More particularly, the bolt pads 39A, 39B may be respectively provided on port and starboard sides of the set of auxiliary buoyant hull sections 15A, 15B (outer side surfaces, opposite to the side surfaces on which the set of auxiliary hull frame sections 31A, 31B are attached) in the deployed hull position. In embodiments, the set of buoyant platforms 38A, 38B may be independent members separate from the marine vessel 1, and be coupled to the set of auxiliary buoyant hull sections 15A, 15B via the bolt pads 39A, 39B after the marine vessel 1 has been deployed in the water. The set of buoyant platforms 38A, 38B may be coupled so as to be coplanar (e.g., form a level surface) with the top surfaces of the set of auxiliary buoyant hull sections 15A, 15B. In embodiments, the set of buoyant platforms 38A, 38B may be formed with a substantially similar structure and material to the set of auxiliary buoyant hull sections. In other embodiments, the set of buoyant platforms 38A, 38B may include airtight pontoons filled at least partially with air to provide additional buoyancy to the marine vessel 1.

Additionally, in embodiments, the set of buoyant platforms 38A, 38B may each include a flooding valve 42A, 42B and a bilge pump 44A, 44B configured to controllably adjust the amount of fluid in the set of buoyant platforms 38A, 38B. More particularly, the flooding valves 42A, 42B may include ball valves, butterfly valves, gate valves, or other types of valves configured to allow ingress of fluid (e.g., water) into the set of buoyant platforms 38A, 38B. The bilge pumps 44A, 44B may include centrifugal bilge pumps, diaphragm bilge pumps, manual bilge pumps, electric bilge pumps or other types of pumps configured to remove fluid (e.g., water) from the set of buoyant platforms 38A, 38B. The flooding valves 42A, 42B and the bilge pumps 44A, 44B may be used to adjust the floatation height of the set of buoyant platforms 38A, 38B relative to the set of auxiliary buoyant hull sections 15A, 15B. As an example, after the marine vessel 1 and the set of buoyant platforms 38A, 38B have been independently deployed on the water and positioned to facilitate coupling, the flooding valves 42A, 42B may allow ingress of water into the set of buoyant platforms 38A, 38B until the set of buoyant platforms 38A, 38B achieve a substantially similar floatation height (e.g., depth) as the set of auxiliary buoyant hull sections 15A, 15B. The set of buoyant platforms 38A, 38B may then be coupled to the set of auxiliary buoyant hull sections 15A, 15B via the bolt pads 39A, 39B. Once coupled, the bilge pumps 44A, 44B may remove the water from the set of buoyant platforms 38A, 38B such that the central buoyant hull section 10, the set of auxiliary buoyant hull sections 15A, 15B, and the set of buoyant platforms 38A, 38B float at the same depth and have top surfaces that are substantially coplanar (e.g., level). The set of buoyant platforms 38A, 38B may be removed from the set of auxiliary buoyant hull sections 15A, 15B after use to facilitate storage and transportation.

By providing the marine vessel 1 with a mountable set of buoyant platforms 38A, 38B and respective flooding valves 42A, 42B and bilge pumps 44A, 44B, it is possible to provide additional buoyancy to the marine vessel 1 to allow for the provision of heavy service equipment (e.g., a larger boom crane).

In embodiments, as illustrated in FIG. 1, 2, 4-7, the marine vessel 1 may be provided with a propulsion system 45A, 45B. The propulsion system 45A, 45B may include outboard motors, diesel inboard motors, electric propulsion systems, hydraulic propulsion systems, or the like, and may be suitably selected to facilitate propulsion of the marine vessel 1 in consideration of the size and weight of the marine vessel 1. By providing the marine vessel 1 with a propulsion system 45A, 45B, the marine vessel 1 may navigate to a desired worksite under its own power, without being towed by another vessel.

As described herein, aspects of the disclosure relate to providing a marine vessel having a boom crane equipped with a coupler mechanism for interchangeably coupling with one or more attachable implements such as a bucket, basket, fork, or the like. By providing the boom of the boom crane with a coupler mechanism such as an ISO 24410 quick-attach coupler, it becomes possible to facilitate efficient and rapid switching between tools, enabling the crane to be adapted to different service operations without the need for significant downtime or complex modifications.

Additionally, as described herein, aspects of the disclosure relate to providing a marine vessel having a set of foldable auxiliary buoyant hull sections configured to rotate around a first set of hinges between a deployed hull position and a stowed hull position. By configuring the first set of hinges and the set of auxiliary buoyant hull sections to form a gap along the central longitudinal axis of the central buoyant hull section between the auxiliary buoyant hull sections in the stowed hull position, it is possible to create space on the central buoyant hull section to accommodate large-scale service equipment, such as a boom crane. As a result, the marine vessel can be manufactured to include the service equipment while maintaining a compact form factor in the stowed hull position to facilitate transport. For instance, the marine vessel according to the present disclosure may be configured to the stowed hull position, loaded onto a trailer, and pulled behind a vehicle to a designated work site to be used as part of a service operation. Additionally, by configuring the set of auxiliary buoyant hull sections to be coplanar with the top surface of the central buoyant hull section in the deployed hull position, it is possible to create a level, continuous surface between the central buoyant hull section and the set of auxiliary buoyant hull sections, extending the effective deck space of the central buoyant hull section and facilitating service operations. In this way, it is possible to provide a marine vessel capable of providing equipment useful for performing a broad range of operational tasks while facilitating overland transport.

It should be noted that the marine vessel according to the present disclosure is not limited to the embodiments described herein, and various modifications are contemplated. As an example, in embodiments, the marine vessel may have a design in which a portion of the respective auxiliary hulls is notched (e.g., cut out) to fit around the service equipment provided on the central buoyant hull section when in the stowed hull position. In this way, service equipment having a variety of sizes and shapes may be accommodated.

DEFINITIONS

The following includes definitions of selected terms employed herein. The definitions include various examples or forms of components that fall within the scope of a term and that may be used for implementation. The examples are not intended to be limiting. Both singular and plural forms of terms may be within the definitions.

An “operable connection,” or a connection by which entities are “operably connected,” is one in which signals, physical communications, or logical communications may be sent or received. Typically, an operable connection includes a physical interface, an electrical interface, or a data interface, but it is to be noted that an operable connection may include differing combinations of these or other types of connections sufficient to allow operable control. For example, two entities can be operably connected by being able to communicate signals to each other directly or through one or more intermediate entities like a processor, operating system, a logic, software, or other entity.

To the extent that the term “includes” or “including” is employed in the detailed description or the claims, it is intended to be inclusive in a manner similar to the term “comprising” as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term “or” is employed in the detailed description or claims (e.g., A or B) it is intended to mean “A or B or both.” When the applicants intend to indicate “only A or B but not both” then the term “only A or B but not both” will be employed. Thus, use of the term “or” herein is the inclusive, and not the exclusive use. See, Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995).

While example systems, methods, and so on, have been illustrated by describing examples, and while the examples have been described in considerable detail, it is not the intention of the applicants to restrict or in any way limit scope to such detail. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the systems, methods, and so on, described herein. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention is not limited to the specific details, the representative apparatus, and illustrative examples shown and described. Thus, this application is intended to embrace alterations, modifications, and variations that fall within the scope of the appended claims. Furthermore, the preceding description is not meant to limit the scope of the invention. Rather, the scope of the invention is to be determined by the appended claims and their equivalents.
