Description

Ship {Ship}

This invention relates to ships.

Liquefied natural gas (Liquefied natural gas), Liquefied petroleum gas (Liquefied petroleum gas) and other liquefied gas are widely used in place of gasoline or diesel in recent technology development.

Liquefied natural gas is a liquefied natural gas that is obtained by refining natural gas collected from a gas field. It is a colorless and transparent liquid with almost no pollutants and high calorific value. On the other hand, liquefied petroleum gas is a liquid fuel made by compressing gas containing propane (C3H8) and butane (C4H10), which come from oil in oil field, at room temperature. Liquefied petroleum gas, like liquefied natural gas, is colorless and odorless and is widely used as fuel for household, business, industrial, and automotive use.

Such liquefied gas is stored in a liquefied gas storage tank installed on the ground or stored in a liquefied gas storage tank provided in a ship which is a means of transporting the ocean. The liquefied natural gas is liquefied to a volume of 1/600 The liquefaction of liquefied petroleum gas has the advantage of reducing the volume of propane to 1/260 and the content of butane to 1/230, resulting in high storage efficiency.

These liquefied gases are supplied to a variety of customers. Recently, an LPG fuel system for driving an engine using LPG as a fuel has been developed in an LPG carrier carrying liquefied natural gas. In this way, LPG The method used is applied to ships other than LPG carrier.

The process of supplying liquefied gas to the liquefied gas storage tank is as follows. First, dry air (air purging) is performed to remove moisture by filling dry liquefied gas storage tank with inert gas, and inerting (N2 purging) is performed to fill inert gas without oxygen. After gasing up to replace the inert gas with cargo (using vaporized liquefied gas), cooling down the liquefied gas storage tank through the liquefied gas is performed to prevent the generation of evaporation gas when the liquefied gas is supplied. do. The liquefied gas used for gasing up and cooling down can be supplied from the outside.
