An expansion deck system for vessels includes an elongated deck body that is pivotally secured to a vessel by a plurality of hinges. The deck body transitions between a folded position that does not affect the overall width of the vessel, and an expanded position that extends outward from the side of the vessel. A plurality of triangular-shaped braces is removably secured to the bottom surface of the deck body. The braces including a first section that extends along an entire width of the deck body and a second section that engages a pontoon of the vessel. An electromechanical bracing unit is positioned along the bottom surface of the vessel and includes a linear actuator that moves an elongated rod between an extended and retracted position, and A power lifting unit transitions the deck body between the folded and extended positions.

The invention encompasses fire-escape models of off-shore rigs with emphasis on a Detachable Island Rig (DIR), the latter instantly unlocked upon a rig-fire from a permanent under-water basement, its water-sealed fire-escape entry serving as an exceptional model (Sumathi Paturu's in-situ model) for an in-site fire-escape of a jack-up rig. An off-site modular is an unlimited air-source for all fire-escape units. A guarded spray-room is a destination for spray-walks, or spray-tracks with track-drives, or else simpler spray-drivesall being safe evacuation accessories workable with minimal cost and space. Wheeled life-boats and lift-boats protected against collision injury, are let out boarded/un-boarded by a remote control. Vital needs like safe evacuation, fresh air, and first-aids are devised as affirmed provisions. Other gas-fire protective outdoor/indoor measures include: gas-chasing surface grid of fans and sprinklers about tall structures; similar grid arching over the rig; and gas-chasing pressured air-circuiting into the rig's interiors.

A marine vessel includes a hull including a cabin, an imager that images a field-of-view shielded region, which is a region in which a marine vessel operator's field of view is obstructed when the marine vessel operator located on an operation seat provided inside the cabin looks around an outside of the marine vessel in a horizontal direction, and a display provided at a position visible from the operation seat and that displays a field-of-view complement image, which is an image of the field-of-view shielded region captured by the imager.

A catamaran having two parallel symmetrical hulls of equal size spaced apart with a superstructure lower deck extending from an outer edge of the first hull to an outer edge of the second hull. The lower deck is positioned above the static waterline and provides a single, constant, flush elevation height across the entire length and breadth of the vessel, with the placement of control and propulsion machinery in the hulls. The improved catamaran has an increased freeboard, increased gross tonnage, and decreased design pressures on the superstructure scantlings of the catamaran deck as compared to a conventional catamaran having a lower deck mounted beneath the static waterline, or accommodations added to the hulls.

The invention relates to a method for constructing habitable installations for floating structures, comprising the following steps: lowering a first adapted standard container (3) through at least one vertical prismatic cavity (25) of a carrying structure (2) until it is supported on support brackets (4) of the floor below; securing the first container (3) to said support brackets (4) of the floor below; and, for each subsequent floor, securing a number of subsequent support brackets (4) to the carrying structure (2) on each container (3) already in position; lowering a subsequent container (3) until it is supported on said subsequent support brackets (4); and securing said subsequent container (3) to subsequent support brackets (4) on which it is resting. The invention also includes a habitable installation (1) constructed according to said method, and a container (3) adapted for carrying out said method.

System and method for controlling representative information about the use by one or more users of one or more habitable locations of a ship, comprising: a plurality of habitable locations, each habitable location comprising a plurality of electrical and/or electronic components controllable during the use of the habitable location by a user; a plurality of local control units, each local control unit of said plurality being operatively associated with at least one portion of habitable locations of the plurality of habitable locations of the ship, each local control unit being configured to control said at least one portion of habitable locations to which it is operatively connected; a central control unit; a data communications network, each local control unit of said plurality being operatively associated with the central control unit via the data communications network.

A sustainable floating community based on a mass-produced modular, pre-fabricated kit of parts referred to as floating modular units. The floating modular units are designed to allow for various needs while remaining simple to deliver and assemble by hand in remote destinations prone to volatile shifts in water levels and currents. The floating modular units are ready to assemble, can be erected for use on land and bodies of water, are easily collapsible for transport, thereby serving as highly adaptable transportable structures.

A jet boat includes a cockpit arranged in a central portion of the jet boat on a boat body centerline, a bulwark provided along a circumference of a deck, and a platform fixed to a stern. In the bulwark, the upper surface of a rear bulwark between the platform and the cockpit is located above the upper surface of a foot space and below the seating surface of a seat.
