The BOG re-liquefaction recovery system for LNG transport vessels uses low-energy and low-cost mixed refrigerant liquefaction technology, employing hydrocarbons with an ODP of 0 and a low GWP for environmentally friendly working fluids. It features a new, efficient rotor-type design based on free curve reverse engineering, significantly improving compressor volume and adiabatic efficiency. The system uses a high-efficiency anti-impact marine oil-cooled semi-hermetic screw compressor with a shaftless seal structure, ensuring high reliability in shipboard environments.
