International supplier of compressors TMC Compressors (TMC) is launching a boil-off gas compressor that can be used on all vessels that use LNG as ship fuel. The compressor system, which will be unveiled at this week’s Nor-Shipping event in Oslo, offers both financial and environmental benefits for users.
“By compressing the boil-off gas to the required pressure in order to supply it as fuel directly into the ship’s engine, you will have an optimal system with regards to energy efficiency,” says Hans Petter Tanum, TMC’s director of sales and business development. “TMC will offer a number of different boil-off gas compressors, ranging from 30 kW to 450 kW.”
Onboard a vessel that uses LNG as fuel, heat from the surroundings increases the temperature inside the cooled down LNG fuel thanks, causing liquid to evaporate. The gas generated from this is known as boil-off gas.
The system captures the boil-off gas from the LNG fuel tanks onboard, compresses it with a TMC compressor and injects it into the main engine as fuel.
The marine boil-off gas compressor system can also be utilized on vessels that run on dual fuel, for example LNG in combination with bunker oil.
