DNV GL has launched a joint development project (JDP) to advance the understanding of the use of lithium-ion batteries in the shipping industry

Classification society DNV GL has announced the launch of a Joint Development Project (JDP), designed to explore how lithium-ion batteries can be used in the shipping industry. More than a dozen partners from the entire value chain have joined the initiative, including flag states, research institutions, battery and propulsion suppliers, fire detection and extinguishing system providers, and ship owners, operators and yards.

“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,” commented DNV GL – Maritime’s director of ship classification and technical director Geir Dugstad. “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.”

“With the new advances in alternative fuels it’s our ambition to actively partner with the maritime industry and contribute to solutions that satisfy vessel safety and environmental impact while also taking the industry’s commercial needs into consideration,” said Norwegian Maritime Authority director general Olav Akselsen.

“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 while also ensuring that these new and advanced technologies can be implemented to a greater extent”, added Scandlines naval architect Rasmus Nielsen.

With a broad range of expertise, knowledge and experience from many different perspectives, DNV GL says it intends to develop a greater understanding of the challenges and requirements of expanding the use of batteries in the maritime realm.

At the end of the JDP the partners hope that they will have enhanced their own understanding so as to optimise their own products and services, while also created a set of inputs that can be taken up by the industry to not only push the development of the batteries themselves, but the associated systems, procedures, and approval processes.

The JDP officially kicked off at the end of 2017, with major tasks defined as follows:

1.    Safety Model Development and Assessment Based on Prior Knowledge

2.    Concerted Lithium-Ion Battery Risk Assessment

3.    Battery Safety Testing Program

4.    Battery Safety Simulation and Analysis Tool Development and Refinement

5.    Project Management, Dissemination, Input to Requirements and Rules

The project will wrap up with dissemination activities in 2019.

Groups from across Europe and throughout the sub-sectors of the shipping industry will be involved, including: Norwegian Maritime Authority; Danish Maritime Authority; Norwegian Defense Research Establishment (Forsvarets Forskningsinstitutt, FFI); Corvus Energy; Plan B (PBES); FIFI4MARINE; Nexceris; Rolls Royce Marine; ABB; ferry operators Stena and Scandlines and shipbuilder Damen – as well as DNV GL.
