LNG membrane tanks take up less space than other types of storage and the exoskeleton concept can be pre-built on the dock before being retrofitted onto an existing vessel eliminating the need for drydocking.
The solution has been developed for existing containerships in the 14,000 – 18,000 teu range. Operating on regular trading routes on the Asia – Europe trade VLCS are seen as good candidates for conversion to LNG as a marine as the bunkering infrastructure develops on the trade lane.
“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 Sulphur 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 optimise our customer’s operational performance.”
The certificate was presented at Marintec China on Thursday.
“This advanced technology is a milestone for cost-effective LNG retrofit and newbuilding solutions for larger vessels. With introduction of LNG as ship fuel there are immediate benefits to ship owners related to a reduced carbon dioxide footprint (EEDI) as well as all other harmful exhaust emissions,” said Hans-Jürgen Voigt, shareholder and managing director of Technolog.
A General Approval for Ship Application (GASA) is a full approval of the technology under consideration, according to the DNV GL Rules for Classification, which examines a typical installation of the technology in a vessel.
