New class notation helps LR2 operators switch between low and high-grade cargoes 

DNV GL announced a new system designed for modern LR2 tankers, with easy-to-clean corrugated tank walls, deep-well pumps and high-performance tank washing machines. Notably, the new class notation is mainly intended for new ships since some criteria, including stripping efficiency, are subject to specific test requirements. Nevertheless, it may be awarded to existing vessels as well, if they meet the criteria. The new ITC rules have been published in July 2019, with an effective date of 1 January 2020.
