Turbo-Brayton as Subcooler - BOG reliquefaction offshore

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.

A Boil-off reliquefaction solution that is suited to a wide range of vessels

• Bunker vessels and bunker barges (from 1,000 to 30,000 m3) 
• LNG-powered vessels
• LNG carriers (from 15,000 to 250,000 m3)
• Multigas carriers
• FSRU and FSU

Off-shore Turbo-Brayton range
