Question 1346 Deck General

The correct answer is D) all of the above. Gas compressors on an LNG vessel serve multiple functions related to the circulation and delivery of boil-off gas from the cargo tanks. They can be used to circulate the gas when warming up the tanks, deliver the boil-off gas to the engine room for fuel, and also deliver gas ashore when loading the vessel. The compressors provide the motive force to move the gas through these various systems as needed to safely and efficiently handle the LNG cargo. The other options are incorrect because they only describe one of the functions of the gas compressors, when in reality they serve all three of these important roles on an LNG carrier.
