MULTI-PURPOSE LIQUEFIED NATURAL GAS PUMP SYSTEM FOR LIQUEFIED NATURAL GAS CARRIERS EQUIPPED WITH DUAL FUEL ENGINES

摘要

The present invention relates to a multi-purpose LNG supply pump system of a liquefied natural gas carrier that is propelled by a heterogeneous fuel engine, the object of which is to construct a liquefied natural gas pump system with a single pump system to secure the space inside the cargo hold, equipment cost And to provide a multi-purpose LNG supply pump system of liquefied natural gas carriers promoted by a heterogeneous fuel engine that can reduce the economic burden by reducing maintenance costs.;The present invention provides a natural gas fuel supply system for supplying natural gas vaporized to a heterogeneous fuel engine, a cargo system cooling injection system for maintaining an appropriate temperature of the cargo hold, and a pressure maintenance for maintaining the appropriate pressure in the cargo hold when liquefied natural gas unloading A liquefied natural gas pump system for supplying liquefied natural gas to a natural gas vaporization system; The first supply pipe for supplying LNG to cargo injection cooling system or the pressure gas supply system for maintaining gas and the second supply pipe for supplying LNG to natural gas fuel supply system are connected to each other to integrate the first and second supply pipes. Connect the LNG supply pipe to the LNG delivery pump installed in the cargo hold, supply the fuel to the heterogeneous engine by one pump, maintain the proper temperature of the cargo hold when loading the LNG, and pressurize the inside of the tank with the vaporized natural gas when LNG is unloaded. It is configured to do so.;Liquefied natural gas, heterogeneous fuel engine, liquefied natural gas carrier, natural gas fuel supply system, cargo cooling system, pressure gas natural gas vaporization system
