GTT has completed a series of tests to verify the capability of its new compact and easy to install liquefied natural gas (LNG) fuel tanks solution LNG Brick.

The tests were conducted under cryogenic conditions and used a prototype of LNG Brick developed by South Korean company Dongsung Fine Tec.

Designed to address the growing trend of using LNG as a fuel, the solution features a Mark III membrane system.

LNG Brick is developed to be a block-ready solution that can be installed into the ship structure.

Construction of the tanks, which are available in various capacities ranging between 1,000m³ and 3,000m³, can be performed outside a shipyard.

Following construction, they can be transported to the shipyard for installation on LNG-propelled vessels.

“Given the current economic environment and LNG price levels, it seems to us to be an appropriate answer to address many of our customers’ concerns.”

LNG Brick is also capable of offering an easier management of boil-off for small volumes due to its ability to maintain a higher pressure than conventional membrane tanks.

GTT chairman and CEO Philippe Berterottière said: “Given the current economic environment and LNG price levels, it seems to us to be an appropriate answer to address many of our customers’ concerns.”

The company currently provides engineering, consultancy, training, maintenance support, and technical design services.

It primarily develops containment systems for the shipping and storage of LNG in cryogenic conditions.
