GTT to design LNG fuel tank for retrofit

The retrofit project has been carried out with Hamburg-based ship designer Technolog, maritime solution provider MAN Energy Solution and its subsidiary MAN Cryo. The project’s design is based on the use of an exoskeleton-type structure which obtained a GASA2 by DNV-GL in 2017. The structure, pre-equipped with GTT’s Mark III cryogenic containment system, will be installed and integrated into a cargo bay of the current vessel.

Philippe Berterottière, chairman and CEO of GTT, commented: “We are very proud to take part in this project with the Mark III membrane containment system.

“It will be the first ever retrofit of this kind for the use of LNG as a marine fuel. GTT is pleased to answer its client’s requirement with tailor made solutions in a challenging environment.”

By using the ship’s structure as a support, the exoskeleton solution reduces the weight of the tank and shortens the retrofit time of the ship. This 6,500 m3 LNG tank will offer more efficient space utilisation for fuel storage.

The retrofit is due to be completed during the first quarter of 2020.
