What is the function of the BOG (Boil-Off Gas) compressor on LNG fueled vessels?
Direct Answer
Option A: Compress boil-off gas for use as fuel in main/auxiliary engines or boilers
Boil-off gas (BOG) management is critical for maintaining fuel tank pressure within design limits. The BOG compressor recovers vapor generated by heat ingress, compressing it for utilization in the vessel's dual-fuel engines or boilers, thereby optimizing fuel efficiency and preventing unnecessary venting in accordance with IGF Code requirements.
