AiP for LNG membrane tank maintenance optimisation tool

GTT notes that the approval project has been conducted in close collaboration with Shell International Trading and Shipping Company Limited (STASCO) whose operational experience supported the validation of the use cases.

The digital solution draws upon GTT’s “Sloshing Virtual Sensor” solution, which builds on data from GTT’s motion analysis platform, and real-time operational data from the LNG carrier to monitor the evolution of critical parameters with regards to tank integrity. 

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. This will translate into increased operational flexibility and substantial cost savings for shipowners and charterers.

Philippe Berterottière, Chairman and CEO of GTT, said: “This Approval in Principle 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 Approval in Principle 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 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.”
