Embodiment Construction

[0020] Such as figure 1 The watercraft 1 shown in FIG. 1 is equipped with a main engine 2 that powers the propulsion system 3 of the watercraft. Obviously, the number and layout of the installed engines can vary according to the type and size of the watercraft. The engine 2 operates on gaseous fuel, and the gaseous fuel is stored in the fuel tank device 4 in liquid phase. In practice, this means that the temperature of the gas is generally about minus 162°C. The engine 2 is installed in the engine compartment 5. The engine compartment is equipped with an engine compartment housing 6 extending from the engine compartment to the outside of the watercraft 1, through which, for example, the exhaust pipe of the engine can be laid. in figure 1 In the embodiment, the fuel tank device 4 is arranged in the vicinity of the engine compartment shell that is longitudinally aligned above the bulkhead deck 8. The fuel tank device 4 is connected to the engine 2 through an air supply system 7...

Abstract

A marine vessel (1) operated with gaseous fuel having at least one gas powered engine (2), which vessel is provided with a fuel tank arrangement (4) in which the fuel is stored in liquid phase, in which vessel the engine is positioned in an engine room which is provided with an engine room casing (6) extending from the engine room to exterior of the vessel, The fuel tank arrangement (4) is arranged in vicinity of the engine room casing.

Description

Technical field [0001] The present invention relates to a watercraft operating with gas fuel, which has at least one gas-powered engine, the watercraft is equipped with a fuel tank storing fuel in liquid phase, and the engine is placed in an engine compartment in the watercraft, The engine compartment is equipped with an engine compartment housing that extends from the engine compartment to the outside of the watercraft. Background technique [0002] Compared with, for example, heavy fuel oil or marine diesel, gas fuels are increasingly used on various types of watercraft due to their clean combustion and availability. [0003] Gas is generally stored in a cryogenic fuel tank in liquid form, which is also a pressure vessel. Since the traditional air box is a large pressure vessel, when considering the economy and convenience of using the water transportation tool, the space utilization in the water transportation tool is critical, so the positioning of such a gas box or several ai...
