Torgy LNG’s updated LNG Type A tank design has been granted a General Approval for Ship Application (GASA) by classification society DNV GL. The original design was the first LNG tank based on the IMO A atmospheric design to have been awarded a GASA certificate. “This review sets a new milestone for our modified LNG Type A tank design,” says Sven Halvorsen, CEO of Torgy LNG. “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 commercialization of the tank design,” Sven added. Torgy LNG received an GASA statement for a previous design of the LNG tank, but this design has now been modified with a total redesign of materials and geometrical design solutions of the secondary barrier. These modifications have been tested and documented by numerical analysis. The tank design is well suited for larger cargo tanks. “We are very pleased to be able to present Torgy LNG with this GASA statement,” said Johan Petter Tutturen, Business Director for Gas Carriers at DNV GL. Johan added: “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.” Torgy LNG delivers turnkey solutions including engineering, project consultancy, planning, purchasing, project management, and installation of LNG storage and fuel systems for shipping as well as land-based industries.
