Engineering firm GTT said it has obtained approval in principle (AIP) from testing, inspection and certification group Bureau Veritas for the use of a digital solution for sloshing activity assessment in the Framework of Class Survey in order to optimize the liquefied natural gas (LNG) membrane tank maintenance frequency.

GTT said the digital solution is based on its "Sloshing Virtual Sensor" technology, using the tank digital twin, also designed by GTT, and the real-time operational data of the floating units (FSRU2, FLNG3 and LNGC4) to monitor the evolution of critical parameters with regards to the tank integrity.

Combined with an appropriate risk analysis, the solution can support Alternative Survey Plans aiming at optimizing the tank maintenance while complying with strict safety standards. According to GTT, this will translate into increased operational flexibility and substantial cost saving for the shipowners.

Philippe Berterottière, Chairman and CEO of GTT, said, "Artificial intelligence combined with the expertise of GTT's teams has made it possible to develop a unique digital solution to optimize 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 ship-owners, in order to help them adapt to an increasingly demanding commercial environment."

Matthieu de Tugny, Executive Vice President Marine & Offshore at Bureau Veritas, said, "Digitalization combined with artificial intelligence is a major transformation for the shipping industry bringing new challenges and opportunities. I am proud Bureau Veritas helped GTT to pioneer this digital solution for sloshing activity assessment in the framework of class survey (using sloshing model tests, real-time operational data and machine learning) with the highest safety standards. This demonstrates not only our technical expertise in the fields of sloshing for gas carriers but also our strong competencies in digitalization and artificial intelligence."

Ship Recycling: Ship Scrap Prices Soar to Nearly $500/ton During the Pandemic

“Everything has a life cycle and that life cycle changes,” said Dr. Sharma. “For example, cruise ships tend to have the longest life cycles, but when COVID hit, a lot of cruise ships were recycled. Otherwise, the shortest life cycle I'm seeing right now is in the offshore space, where we are seeing vessels 10 years old and even younger units being recycled. It is insane.” Image Courtesy GMS

Dr. Anil Sharma is a wealth of knowledge on ship scrapping, having started GMS 25 years ago
