RELIQUEFYING DEVICE INSTALLED ON LIQUEFIED GAS CARRIER

摘要

A reliquefaction device mounted on a liquefied gas carrying ship is provided with a compressor which compresses boil-off gas resulting from flammable liquefied gas, and an explosion-proof motor which drives the compressor. Since the explosion-proof motor is used, even in the unlikely event that an explosion occurs inside the explosion-proof motor, the container for the explosion-proof motor is not destroyed, and a situation is prevented where sparks fly out of the container and ignite flammable gas. Therefore, it is unnecessary to separately place the explosion-proof motor and the compressor in different chambers partitioned by a bulkhead. As a result, there is a higher degree of freedom in the onboard placement of the reliquefaction device.
