The invention relates to a marine surface vessel (1), in particular a passenger ship, extending in a longitudinal direction between a bow (2) and a stern (3), comprising least one power providing apparatus (6) operatively connected to at least one propulsion unit (7) for propulsion of the vessel, a fuel tank arrangement (8) for storing gaseous fuel in a liquid phase, connected to the power providing apparatus (6) by means of a gas supply system for running the power providing apparatus (6), and a plurality of decks (91-98) distributed vertically, one above the other, the fuel tank arrangement (8) comprising two tank sub-arrangements (81, 82), each tank sub-arrangement comprising at least one gaseous fuel tank (811, 812, 821, 822), each fuel tank extending vertically past at least two of the decks (92-95), and at least two of the decks (92-95), past which the fuel tanks (811, 812, 821, 822) extend, each presents a passageway (941) extending between the tank sub-arrangements (81, 82).

The spilled fuel collection system is configured for use with the fuel vent of a vessel. The fuel vent is designed to release gas and fuel during an event selected from the group consisting of: a) a build-up of gas pressure within the fuel tank; and, b) overfilling the fuel tank with fuel. The spilled fuel collection system is an accessory that captures fuel and fuel vapors that escape through the fuel vent of a vessel during the fueling process. The spilled fuel collection system comprises a transportable fuel container, a hose, and a quick connect fitting. The transportable fuel container captures the fuel and vapor that escape through the fuel vent. The hose transports the escaped fuel and vapor from the fuel vent into the transportable fuel container. The quick connect fitting secures the hose to the fuel vent.

A leak-sealing device for sealing a leak in a container, a tank and/or a pipe includes a housing-type carrier unit, at least one expandable sealing member provided on an end region of the carrier unit, which does not expand, or only a little, in the storage position thereof, and at least one fluid connection and/or at least one fluid-release unit which is coupled to the carrier unit in such a way that, during the supply of fluid, the leak-sealing member is at least partially filled and expanded with the fluid in the sealing position thereof by means of a fluid supply. A method for sealing a leak using the leak-sealing device and to a system including the leak-sealing device and a fluid-supply device utilizes a release unit for fluid release.

A power-saving type liquefied-gas-fuel ship includes: a liquefied gas storage tank storing liquefied gas; an engine using the liquefied gas stored in the liquefied gas storage tank or boil-off gas generated by spontaneous vaporization of the liquefied gas as fuel; a fuel feeder supplying the liquefied gas as fuel for the engine; a compressor compressing the boil-off gas to a pressure required for the engine; a heat exchanger cooling the remaining boil-off gas not supplied to the engine among the boil-off gas compressed by the compressor; a refrigerant circulation line in which the refrigerant supplied to the heat exchanger circulates; a refrigerant compressor compressing the refrigerant discharged from the heat exchanger after heat exchange in the heat exchanger; and a cold heat recovery device recovering cold heat of the liquefied gas supplied as fuel for the engine to cool the refrigerant compressed by the refrigerant compressor.

Apparatus and methods to couple fuel components to a fuel tank are described. An example method includes coupling a carrier to a guide suspended in a cavity of a fuel tank, where the guide extends in a longitudinal direction between a first end of the guide adjacent a first side wall of the fuel tank and a second end of the guide adjacent a second side wall of the fuel tank opposite the first side wall, and moving the carrier along the guide between the first end of the guide and the second end of the guide.

Various techniques are provided for an expandable energy absorbing fluid bladder. In one example, the fluid bladder includes a primary portion and a secondary portion. The secondary portion can be configured to expand or increase in volume when the fluid bladder is subjected to a pulse greater than a threshold pulse. Expansion of the secondary portion can allow fluid or additional fluid to flow into the secondary portion and thus decrease a peak pulse and, thus, avoid rupture of the fluid bladder.

The invention relates to a marine surface vessel (1), in particular a passenger ship, extending in a longitudinal direction between a bow (2) and a stern (3), comprising least one power providing apparatus (6) operatively connected to at least one propulsion unit (7) for propulsion of the vessel, a fuel tank arrangement (8) for storing gaseous fuel in a liquid phase, connected to the power providing apparatus (6) by means of a gas supply system for running the power providing apparatus (6), and a plurality of decks (91-98) distributed vertically, one above the other, the fuel tank arrangement (8) comprising two tank sub-arrangements (81, 82), each tank sub-arrangement comprising at least one gaseous fuel tank (811, 812, 821, 822), each fuel tank extending vertically past at least two of the decks (92-95), and at least two of the decks (92-95), past which the fuel tanks (811, 812, 821, 822) extend, each presents a passageway (941) extending between the tank sub-arrangements (81, 82).

Herein a floating vessel is disclosed. The floating vessel comprises a deck member and a tank for liquefied hydrocarbon gas such as LNG. The tank extends through the deck member, and the tank is supported by the deck member, suspended at less than of a total height of the tank, seen from the top of the tank.

A vessel including a hull, an upper deck, an accommodation structure extending above the upper deck, a propulsion system powered by ammonia as a fuel, and a tank for storing ammonia for supplying the propulsion system, wherein the tank is located aft of the accommodation structure.
