Friday, September 27, 2013 New tools for assessing Arctic ice loads on LNG shipsBureau Veritas, a global inspection and classification firm, has developed new tools to assess cargo sloshing in ice conditions that should enhance the safety of LNG hauling in the Arctic, according to a company statement. BV says it has developed a probabilistic method for assessing ice loads on structure, which will reduce the time and data needed to assess the structure of vessels and units designed for heavy ice operation, according to a company statement. The new method is the result of collaboration with the State Maritime Technical University of St. Petersburg. A new module for Bureau Veritas' IceSTAR ice load calculation tool will calculate the kinetic energy imparted to the cargo by a collision with ice, the statement said. The kinematics can then be used together with CFD analysis to determine how the cargo will slosh and the extra loads this will impose on the ship's structure and the LNG containment system. "All eyes are on the Arctic sea routes and on the opening up of the Arctic mineral and energy resources," said Pierre Besse, Director of Innovation, Bureau Veritas. "We have to ensure the vessels and offshore units that operate in those extreme conditions are safe. Besse said the new tools will shorten the time needed to assess designs for key Arctic projects and routes.
