In the Framework of Class Survey, Lloyd’s Register, a provider of classification and compliance services to the marine and offshore industries, has granted Approval in Principle (AiP) to the French LNG containment specialist GTT for the use of an innovative digital solution for sloshing activity assessment in order to optimise the LNG membrane tank maintenance.
The approved digital solution is based on GTT’s ‘Sloshing Virtual Sensor’ technology, using a tank digital twin, also designed by GTT, and the real-time operational data of the floating units FSRU, FLNG, and LNGC to monitor the evolution of critical parameters with regards to tank integrity.
GTT said that, combined with an appropriate risk analysis, the solution can support alternative survey plans aimed at optimising tank maintenance by extending the period between tank surveys while complying with strict safety standards, concluding that this translates into increased operational flexibility and substantial cost savings for shipowners and charterers.
Philippe Berterottière, Chairman and CEO of GTT, said: “This AiP is an important milestone in the validation of this cutting-edge digital technology. Artificial intelligence combined with GTT’s LNG core expertise has made it possible to develop this unique solution to help shipowners and charterers reduce their operational costs without compromising vessel safety. We believe that this solution has the potential to become an industry standard in the years to come.”
Panos Mitrou, Global Gas Segment Director, Lloyd’s Register, said: “We are proud to award AiP for GTT’s digital solution for supporting an extension of the time between tank entries after a thorough certification process. This innovative software will provide LNG operators with the opportunity to improve overall safety at sea whilst helping them to reduce cost and stay competitive in the global shipping industry and increasing fleet availability in a challenging energy landscape.”
According to GTT, the approval project was conducted in close collaboration with Shell International Trading and Shipping Company Limited (STASCO) whose operational experience supported the validation of the use cases.
