Bureau Veritas has issued Approval in Principle (AiP) for a digital system, developed by Gaztransport & Technigaz (GTT), for LNG membrane tank maintenance. Based on the company’s “sloshing virtual sensor” technology and using its tank digital twin, real-time operational data from floating LNG assets – including ships, storage and regasification units and offshore production plant – can be monitored to gauge continuous tank integrity.
With appropriate risk analysis, the GTT system can be used to optimise tank maintenance in line with relevant safety standards. This translates to improved operational flexibility and cost savings for asset operators, the company said.
GTT’s chairman and CEO, Philippe Berterotière, commented: “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. With this new cutting-edge digital solution, GTT is putting its innovation and technological know-how at the service of shipowners, in order to help them adapt to an increasingly demanding commercial environment.”
