A recent study by GTT Group, Lloyd’s Register and Shell International Trading and Shipping Company Limited proposes that it may be possible to extend tank inspection intervals on liquefied natural gas (LNG) vessels, thanks to advances in predictive and monitoring technology.
Advances in predictive technology in inspection
This study, carried out jointly by GTT Group, Lloyd’s Register and Shell International Trading and Shipping Company Limited , suggests that inspections, currently required every five years under the International Gas Carriers Code (IGC) and IACS UR Z16 rules, could be spaced out more without compromising security.
For example, Ascenz Marorka, a subsidiary of GTT Group, plays a key role through its “Virtual Sloshing Sensor” technology, which uses a digital twin of the tank and real-time operational data , to assess sloshing activity on vessels. and monitor its critical integrity parameters.
This system supports the extension of inspection intervals while optimizing tank maintenance and improving operational flexibility, resulting in cost savings. Anouar Kiassi, general director of Ascenz Marorka, highlights that this collaboration between industry leaders registers an important fact in improving the design and operations of LNG vessels .
