An aquatic support vessel including a storage rack configured to stow one or more modular marine vessels. The aquatic support vessel further includes a gantry crane having a rigid, extendable column configured for lifting one or more of the modular marine vessels out of the storage rack and placing one or more of the modular marine vessels into the storage rack.

A gas supply marine vessel and a refueling facility are described. The gas supply marine vessel includes a hull with an upper deck having an elongated cargo cavity formed therein. Gas interface modules are disposed in the cavity and extend between hull sides, each module having a plurality of fuel vessel docking stations. A plurality of stacked fuel container assemblies are fluidically coupled to the docking stations. A gantry, is movable along the length of the cavity, straddles the cargo cavity between hull sides. An articulating crane is mounted on the gantry and it utilized to move fuel container assemblies to a fuel container depression formed in the deck of a floating refueling facility. The floating refueling facility includes a concave side to facilitate mooring adjacent a shoreline, the concave side forming angled extensions at corners of the deck with a linkspan extending from each of the angled extensions.

A system and method for transporting cargo and containers across a body of water having at least one mothership vessel designed to carry at least one deployable and retrievable vessels within a hull portion of the at least one mothership vessel. The mothership vessel is designed to partially submerge its hull to flood its well deck wherein the plurality of deployable and retrievable vessels may be deployed or retrieved, the deployable and retrievable vessels allowed to float when the well-deck of the mothership vessel is flooded. At least one mathematical model is used to find a solution for given routes along one or more legs between ports, the mothership vessel, and the deployable and releasable vessels, the route substantially to manage supply chain optimization of the cargo carried on the mothership vessel and the costs and pace of travel. Machine learning may aid in calculations.

A containerized battery system can include a container, a framework, battery cells, and an electrical coupling. The container can be installed within and removed from a container space on a vessel. The framework can be situated within the container and can define multiple framework compartments therein. The battery cells can be arranged into battery modules that provide power to the vessel. Each battery module can be removably disposed as a combined unit within a framework compartment. Each battery cell within a battery module can be coupled together in parallel and the multiple battery modules can be coupled together in series. The electrical coupling can be configured to facilitate the recharging of the battery cells while the battery cells are within the container. The containerized battery system can also include a fire prevention system, an environmental control system, and a power management system.

A steering mechanism for a container carrier ship hull including a bow, a stern, and a container bay therebetween. The bow is provided with a set of depending lateral thruster pods, the set including a first pod disposed along a longitudinal centerline of the hull, a second pod disposed rearward of the first pod and outward from the centerline, and a third pod disposed rearward of the first pod and outward from the centerline opposite from the second pod. The first and second pods define a first longitudinal flow channel to one side of the centerline and the first and third thruster pods define a second longitudinal flow channel to the opposite side of the centerline. A fourth pod, which may omit thruster mechanisms, may be disposed along the centerline reward of the first, second, and third pods, to define with them first and second cross-centerline flow channels.

Generally, an apparatus including a base removably mountable to a vehicle or craft and configured to secure a cooler and/or a paddle. Specifically, a watercraft accessory including a base removably mountable to a watercraft and configured to secure a paddle and/or a cooler.

A lock system for holding transport containers, the system including one or more pairs of brackets, each bracket including frame guides, axle guides and gusset plates. The frame guides are coupled to a major surface of a bracket body of the bracket and have guide walls projecting perpendicularly from the major surface to form frame openings. The axle guides are coupled to and project perpendicularly from the major surface and each of the axle guides surround first thru-holes in the bracket body. The gusset plates couple one of the guide walls to the major surface and the gusset plates have one or more second thru holes therein. A method of assembling the system is also disclosed.

A modular crew cabin system includes a plurality of crew cabin modules interchangeably installable within a plurality of spaces within one or more decks of a ship. A crew cabin module can include four walls, a ceiling, a floor, an upper bunk, and a lower bunk. The upper bunk and the lower bunk are disposed adjacent to two different walls in an L-shaped configuration. The ceiling includes a lower portion and a pop-up portion disposed above the upper bunk such that a 6-foot-tall occupant can sit up comfortably within either the upper bunk or the lower bunk. The pop-up portion of the ceiling may extend higher than an industry-standard ceiling height while permitting utility conduits to be routed over the lower portion of the ceiling. Storage space within the crew cabin module may be greater than one cubic meter.

A personal watercraft includes: a watercraft body; a seat provided in an upper portion of the watercraft body; a storage provided in a front portion of the watercraft body; an equipment case provided at a peripheral position of the storage in the watercraft body to allow equipment equipped in the watercraft body to be stored; and a hatch provided in front of the seat to openably and closably cover the storage and the equipment case.
