Class, industry and regulators to study lithium battery

Hamburg - On Friday, DNV GL announced a joint partnership to study the safe use of lithium-ion batteries in shipping. The class society’s partners in the effort include flag states, research institutions, battery and propulsion suppliers, fire system manufacturers, shipowners, vessel operators and yards. DNV GL says that the hope is to identify improvements not just for the batteries themselves, but for the associated systems, procedures, and approval processes: “We put a great deal of effort into ensuring the safety of these new alternative systems, but the cost of the present safety and approval methodology is cumbersome. This collaborative effort gives a chance for an even greater level of safety,” said Rasmus Nielsen, a naval architect and officer at project partner Scandlines. The project’s deliverables are focused on safety.

Tasks include the development of a safety model based on prior knowledge; a concerted lithium-ion battery risk assessment; a battery safety testing program; battery simulation and analysis tool development; and implementing the findings: “Including batteries in ships, whether as a hybrid or fully electric system, offers the industry the opportunity to improve fuel economy, reliability and operational costs,” says Geir Dugstad, Director of Ship Classification and Technical Director in DNV GL – Maritime. “For this technology to fully take hold, however, knowledge and requirements must be in place to ensure that we have products and a safety regime that address the concerns of all stakeholders while also creating the conditions for this technology to take off in the market.”

The project partners include the maritime authorities of Denmark and Norway; battery builders Corvus Energy and PBES; ABB and Rolls Royce Marine; DNV GL; ferry operators Stena and Scandlines; sensor and fire control firms FIFI4Marine and Nexceris; and shipbuilder Damen.
