LNG gas supply system on deck transport ship

Abstract

The invention provides a LNG gas supply system on a deck transport ship, and the LNG gas supply system includes at least one LNG fuel tank, at least one set of fuel filling and containment system, a LNG fuel pressurized gasification/heating system, a gas supply auxiliary system, and a safety monitoring/emergency shutdown system; the fuel filling and containment system and the LNG fuel tank constitute a connection loop, and the LNG fuel pressurized gasification/heating system gasifies and heats LNG fuel to a dual fuel main engine; the gas supply auxiliary system provides a heating heat source for the LNG fuel pressurized gasification/heating system; and the safety monitoring/emergency shutdown system is used to monitor liquid level, pressure and temperature of the LNG fuel tank, a LNG leakage monitoring system, a fire detection system and an emergency shutdown system. The LNG gas supply system has two sets of fuel filling and containment systems, any one of the fuel filling and containment systems is easy to fill, and two sets of LNG barge/spray pumps are arranged and facilitate controlling of the pressure in the LNG fuel tank and ensuring of the stability and reliability of the gassupply system.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to an LNG gas supply system on a deck carrier. Background technique [0002] At present, the way of LNG transportation in the world is basically to liquefy natural gas and load it into special ships, transport it globally through oceans and rivers, and then process it on the shore, enter the pipeline network, or transport it by road or railway. However, a large amount of pipeline investment is high, the investment recovery period is long, and the depreciation cost is too high. Road and rail transportation have higher requirements for the safety of the transportation method. [0003] At present, the areas that are close to the gas source but cannot be covered by the pipeline network basically require LNG logistics companies to carry out road and water transportation. Since most of the LNG projects are distributed along the coast, along the river and near the terminals of the West-East...
