The technology uses digital twins and real-time data to model and predict movement of cargo in FSRU, FLNG and LNG carrier tanks
GTT has obtained approval in principle (AiP) from Bureau Veritas for the use of digital sensor technology to monitor and model sloshing activity inside LNG membrane tanks.
A statement from the France-based LNG tank design firm said the digital technology would aid operators in maintaining their LNG membrane tanks and prevent degradation of the tanks’ integrity.
"Combined with an appropriate risk analysis, the solution can support alternative survey plans aimed at optimising tank maintenance while complying with strict safety standards. This will translate into increased operational flexibility and substantial cost savings for shipowners," the GTT statement said.
The technology is based on a GTT virtual sensor technology and uses digital twins of the tanks designed by GTT, and real-time operational data from FSRUs, FLNGs and LNG carriers to "monitor the evolution of critical parameters with regards to the tank integrity".
Bureau Veritas executive vice president marine and offshore Matthieu de Tugny said “Digitalisation combined with artificial intelligence is a major transformation for the shipping industry bringing new challenges and opportunities... Our role remains more than ever to help the industry understand – and address – both risk and opportunity as we look into future technologies.”
GTT chief executive Philippe Berterottière said “Artificial intelligence combined with the expertise of GTT’s teams has made it possible to develop a unique digital solution to optimise the frequency of tank maintenance, while guaranteeing the highest safety standard."
