The Turbo-Brayton technology for Boil-Off Gas (BOG) reliquefaction has been specifically developed for marine applications; for shipyards, charterers or ship-owners.
It is a fast and easy-to-install skid-mounted product, that is suited to both atmospheric and pressurized storage. With cooling power available instantaneously from stand-by mode to full capacity and low electrical consumption, Turbo-Brayton technology is extremely reliable. Its maintenance interval is 5 years.
The Turbo-Brayton range has reliquefaction capacities varying from 0.2 t/h to 1.8 t/h, and more by duplicating modules. This boil-off reliquefication system can be installed on both new constructions and retrofitted vessels.
Safe technology – inert process gas, no permanent refill of process gas required
Fast and easy integration – no impact on tank design, retrofit-friendly
Low electrical consumption
Designed for unmanned operation
Technology in action
The first bunker vessel to be fitted with a reliquefaction system will use the Turbo-Brayton technology.
Manufactured by STX shipyard, the owner is Shell and the bunker vessel is in operation since June 2017. Following the Cardissa (Shell Bunker vessel) success, several others LNG bunker vessels will be equipped with Air Liquide Turbo-Brayton reliquefaction solution.
Air Liquide has also provided two LNG reliquefaction units Turbo-Brayton ("TBF-1050"), which will be installed on two LNG carrier vessels 174K manufactured by Samsung Heavy Industries. Those LNG carrier vessels have been ordered by GasLog Ltd and will be chartered by Shell. The Turbo-Brayton cryogenic system liquefies LNG on board, to avoid any flare of Boil Off Gas (BOG) during voyage.
