Liquefied natural gas (LNG) power ship fuel tank capable of being quickly replaced and mounted

Abstract

The invention discloses a liquefied natural gas (LNG) power ship fuel tank capable of being quickly replaced and mounted. The LNG power ship fuel tank comprises a fuel tank frame and an LNG low-temperature gas storage tank arranged in the fuel tank frame, and first fixed connecting holes are respectively formed in the six corners of the upper end of the fuel tank frame. Second fixed connecting holes are formed in the six corners of the bottom of the fuel tank frame correspondingly. Pre-embedded lock fasteners are arranged on the deck of a power ship, and after the fuel tank frame is placed on a ship body, the second fixed connecting holes in the six corners of the bottom of the fuel tank frame are in butt joint with the pre-embedded lock fasteners and then are relatively locked through stud locks. The LNG power ship fuel tank capable of being replaced and mounted can be separated from the ship and can be rapidly connected with the ship, the filling mode requirement of ship LNG fuel supply is met, and the problems that existing ship filling is difficult, the filling station approval procedure is tedious, and the safety risk is large are solved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a rapidly replaceable LNG-powered ship fuel tank. Background technique [0002] As a clean and efficient gas fuel, natural gas has become an important energy source for economic development in the 21st century due to its remarkable characteristics in terms of environmental impact and energy efficiency. The development of liquefied natural gas (LNG) technology is accompanied by the progress of energy technology, cryogenic technology, material technology, etc., so it is widely used in automobiles, ships, airplanes, trains and other transportation tools and cold energy utilization and other fields. [0003] Domestic LNG fuel water filling methods can be generally divided into four categories: [0004] The first type, tanker-ship filling method (TTS) [0005] That is, the tanker for transporting LNG directly fills the ship-borne LNG fixed gas tanks moored at the port. A special low-...

AI Technical Summary

Problems solved by technology

[0014] In view of the above technical problems, the present invention provides a filling method that can be separated from the ship and quickly connected, and can meet the LNG fuel supply of the ship. After the LNG fuel tank of the ship is used up, the whole fuel tank is unloaded from the ship and replaced with a new one. Fuel tanks, which solve the problems of difficult refueling of existing ships, cumbersome approval procedures for refueling stations, and high safety risks
