Problems solved by technology

[0007] However, the placement of tank installations as suggested in EP2029421B1, especially in passenger ships such as cruise ships, would limit the provision of utilities that are functional and beneficial on board (requiring the crew to move quickly and easily transport items such as luggage, food, equipment, etc. items) the possibility of the interior of the ship

Embodiment Construction

[0042] figure 1 A surface vessel at sea is shown in the form of a passenger ship, more particularly a cruise ship 1 . The cruise ship 1 extends in the longitudinal direction between the bow 2 and the stern 3 of the cruise ship 1 . The cruise ship has a hull 4 and a superstructure 5 above the hull 4 . The cruise ship 1 has a power supply in the form of two internal combustion engines 6 . The internal combustion engine 6 is operatively connected to a corresponding propulsion unit 7 for propelling the cruise ship 1 . The propulsion units 7 are here provided as azipull thrusters, but they may of course be provided in any suitable form, eg as some other type of pod propulsion unit, a propeller and rudder combination, or water jets.

[0043] The cruise ship 1 comprises a fuel tank arrangement 8 for storing gaseous fuel, in this example LNG (Liquefied Natural Gas), in liquid phase. The fuel tank arrangement 8 is connected to the internal combustion engine 6 via an air supply syst...

Abstract

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).

Description

technical field [0001] The invention relates to a sea surface vessel, in particular a passenger ship, extending in longitudinal direction between the bow and the stern, comprising: at least one power supply means operatively connected to at least one propulsion unit for propelling the vessel; and A fuel tank arrangement for storing gaseous fuel in a liquid phase is connected to the power supply unit by means of an air supply system for operating the power supply unit. Background technique [0002] The use of gaseous fuels in marine vessels is desirable because it burns cleaner than heavy fuel oil or marine diesel, and because it is now more readily available than said traditional fuel types. It is known for example from US6237347B1 and JPH02109792A to use fuel from the cargo tanks in LNG (Liquefied Natural Gas) cargo ships for ship propulsion. Passenger ships and vehicle transport ships based on LNG propulsion have also been produced. [0003] LNG is usually stored in pres...
