LNG fuel supply system for ship

Abstract

The invention provides an LNG fuel supply system for a ship. The LNG fuel supply system for the ship comprises a fuel tank and a gas supply unit, wherein the fuel tank is used for storing LNG, and thegas supply unit is arranged at one end of the fuel tank and used for supplying gas to the outside; the LNG fuel supply system for the ship further comprises an enclosure device, a reinforcing deviceand at least two supports; the supports are arranged at the bottom of the fuel tank in the axis direction of the fuel tank in a spaced manner to support the fuel tank; the enclosure device covers theexterior of the gas supply unit and supports the gas supply unit; the enclosure device is fixedly connected with the fuel tank and extends outwards from one end of the fuel tank in an impending manner; the reinforcing device is arranged at the bottom of the enclosure device, extends to the bottom of the fuel tank and is connected and fixed to a neighbouring support; and the bottom surface of the reinforcing device is higher than the bottom surface of the support. The LNG fuel supply system for the ship, provided by the invention, has the advantages that good strength and rigidity are realizedbecause the fuel tank, the enclosure device and the supports are connected by using the reinforcing device to form an integrated structure, the enclosure device is placed in an impending manner to reduce the cost of a hull base placed on the ship, and the layout requirement of a ship form with compact space is satisfied.

Description

Technical field [0001] The invention relates to a marine fuel supply system, in particular to a marine LNG fuel supply system. Background technique [0002] In order to save energy and reduce emissions in the shipping industry, the International Maritime Organization (IMO) requires that the sulfur content of fuel be reduced from July 1, 2010. Beginning in 2010, the sulfur content of fuel oil must be less than 1%, and from 2020 it will be reduced to 0.5%. This related policy has gradually promoted the "oil-to-gas" progress in the shipping industry. In recent years, the domestic research and development of LNG fuel supply system for marine ships has been gradually carried out. LNG fuel gas supply system [0003] The conventional structure of the existing LNG fuel gas supply system for marine ships includes a fuel tank and a gas supply unit. The gas supply unit leads the liquid medium in the fuel tank to gasify and supply gas to the ship engine. The gas supply unit is integrated in ...
