DNV GL grants GASA for Torgy LNG’s updated LNG tank design

DNV GL has announced that it has granted a General Approval for Ship Application (GASA) for Torgy LNG’s updated LNG Type A tank design. The original design was the first LNG tank based on the IMO A atmospheric design to have been awarded a GASA certificate.

The CEO of Torgy LNG, Sven Halvorsen, said: “This review sets a new milestone for our modified LNG Type A tank design.

“The results have shown significant improvements and the design concept, based on a type A tank, has many benefits compared to several of the alternative designs. Without DNV GL’s engagement and clear feedback throughout the whole design process we would not be where we are today. Receiving the GASA statement demonstrates that we are on the right track and are better prepared for a commercialisation of the tank design.”

Torgy LNG was granted a GASA for an earlier design of the tank, but this has now been modified significantly, including a total redesign of materials and geometrical design solutions of the secondary barrier. These modifications have been tested and documented by numerical analysis. In the statement, DNV GL claims that the tank design is suitable for larger cargo tanks.

The Business Director for Gas Carriers at DNV GL, Johan Petter Tutturen, said: “We are very pleased to be able to present Torgy LNG with this GASA statement.

“The development process has been ongoing for some time and we have cooperated very closely with the team at Torgy LNG to ensure that they have the input they need to meet the GASA requirements. Working with unconventional design solutions is always a rewarding challenge, as they force us to examine and apply our thinking in new ways so that we can be sure that they meet the safety levels set down in the DNV GL rules and other relevant regulations.”
