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 method and apparatus for rapid loading stacks of items aboard vessels which can include rotating palletized items to depalletize the items, and then placing the items on a lifting robot, lifting the robot and items into the hold of a vessel, removing the items from the robot using a load push lift truck, and then using the load push lift truck to stow the items in a stowage location. The empty robot can be removed from the hold of the vessel and put in a position to receive a another depalletized stack of cartons. In one option the robot has a plurality of fork channels for receiving the blades of a load push lift truck along with receiving the blades or a rotating lift truck.

A method for the use in offshore crew transfer when transferring a person between a crew transfer vessel and a structure or vice versa where a prediction system for predicting vessel bow motion in response to sea waves detected by said wave detection device is used. An indicator is adapted to indicate a prediction of vessel bow motion below a first bow motion threshold value within a first predetermined time period based on said prediction system. The transfer of the person only takes place when said vessel bow motion is indicated to be below the first vessel bow motion threshold value within the first predetermined time period.

A passenger vessel 10 configured to moor along an improved or unimproved shoreline to load or unload the vessel via the bow includes a hull 20 having a movable, openable bow member 24 configured to be moved between a closed state and an open state which exposes the hull's interior volume and an extendable and steerable ramp assembly 14 including an elongated extendable ramp member 78 configured to be stowed in the hull's interior when the bow member is in the closed state. The ramp member is extendable by being conveyed forwardly through the bow opening to define a distally projecting ramp extension supported and steerable (vertically and laterally) from a pivot or swing mount frame 84 affixed within the hull 20.

A watercraft boarding apparatus is herein presented, the watercraft boarding apparatus including a frame adapted to be secured to an object, a pivotable platform pivotably secured to the frame about a pivot axis thereof, the pivotable platform being configured to pivot between an extended configuration for securing a watercraft on water and a boarded configuration supporting the watercraft thereon and a pair of connecting members secured to the pivotable platform to secure the watercraft, wherein pivotal of the platform is adapted to progressively board the watercraft on the platform by sharing a weight of the watercraft between the pivot and water. A method of use and a kit thereof are also contemplated and remain within the scope of the present specification.

An improved hull penetration assembly, and various components thereof are provided. These include a hull penetration mount with braces thereon, as well as a hull penetration mount comprising a lower chamber and a removable hatch coupled thereto. These further include a kit comprising these and other improvements together with a plug insertion apparatus, an object delivery apparatus, a light delivery apparatus and a borescope apparatus.
