Turbo-Brayton as Subcooler - BOG reliquefaction offshore

Turbo-Brayton cryogenic systems for the reliquefaction of Boil-Off Gas

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 3 t/h, and more by duplicating modules. This boil-off reliquefication system can be installed on both new constructions and retrofitted vessels.
