DNV GL says it has presented GTT and its partner TECHNOLOG with a General Approval for Ship Application (GASA) statement for the retrofit of very large container vessels with exoskeleton membrane liquefied natural gas (LNG) tanks.

The solution, which offers more effective space utilisation for cargo storage and as fuel tanks, is intended to enable ship owners to more easily refit existing vessels with a LNG fuel system.

"The GASA approval issued by DNV GL is very important for us, as it shows that the new solution can be ordered and retrofitted today," said Philippe Berterottière, Chairman and CEO of GTT.

"It will allow interested shipowners to get ahead of the IMO’s 2020 Global Sulfur Cap regulations, giving customers and charterers greater certainty as we head to this significant regulatory change. By bringing this solution to market, GTT reaffirms its position as an innovative provider for the industry, continually working to optimize our customer’s operational performance."

The exoskeleton concept, which was developed by GTT in partnership with TECHNOLOG, has a structure that can be prebuilt on land and installed as a complete unit in the hull of the vessel to reduce construction time.

The solution has been developed for container vessels with a capacity of 14,000 to 18,000 TEU.

The GASA approval was presented at the Marintec 2017 conference and exhibition in Shanghai.
