BV addresses risk of sloshing LNG in Arctic operations

BV addresses risk of sloshing LNG in Arctic operations
Bureau Veritas (BV) has launched an initiative to develop tools allowing for safer transit of LNG cargoes in the Arctic.

The software, designed in conjunction with State Maritime Technical University of St Petersburg, is an upgrade for BV’s IceSTAR tool, assesses the effects of cargo sloshing in ice conditions, calculating the kinetic energy imparted to the cargo by collision with ice. The findings will then be used to calculate how much LNG cargo is safe to load, and reduce the risk of structural failure on Arctic vessels. The classification society said that the move will reduce the time and data needed to assess polar vessel designs.

“When gas and oil cargoes begin moving regularly through the Arctic it is certain that ships and ice will interact. The energy from those collisions will cause the cargo to move violently, and we have to make sure the ships and especially LNG containment systems are built to withstand that,” said BV director of Innovation, Pierre Besse. “It is a complex calculation requiring high level modelling but we can do that, and do it in a commercially acceptable time frame. BV is working on a number of high Arctic projects such as Shtokman and Yamal and these tools will make them safe and ready more quickly.”
