Presentation

Lithium-ion battery system – safer installations on board

This presentation will cover lithium-ion batteries as an energy storage system installed on board marine vessels and offshore facilities. It will include battery safety installation considerations from the point of view of a classification society and its lessons learned from the maritime industry; battery risk assessment; battery thermal runaway; basic principles of the interaction of the battery management system (BMS) and the vessel’s power management system (PMS); use of the energy storage system (ESS) for a vessel’s peak shaving operational mode; operational considerations – pros, cons; operation, maintenance, survey and test requirements from the ABS class perspective.
