Building battery confidence: project unites stakeholders around battery fire facts
Key industry stakeholders joined forces in a DNV GL-led joint development project on managing explosion and fire risks related to lithium-ion maritime battery systems.
Players form the entire value chain were invited to examine relevant safety aspects of marine batteries. Overall, the Norwegian, Danish and US maritime authorities were involved, together with battery manufactures, system integrators, suppliers of fire extinguishing systems, shipyards and shipowners.
The study was concluded in late 2019. In general, the study:
Established a fact basis for fires in battery installations, by collaborating across company borders.
Resulted in better battery understanding. E.g. the project examined what happens when lithium-ion battery cells are overheated to the point of failure, thermal runaway, and evaluated several common methods of minimizing harm from these events.
As part of the project delivery was a proposed model for quantitative risk assessment for battery systems. The study involved testing of fire suppression systems. Results showed that they provide different benefits, each with various strengths and drawbacks. No silver bullet solution was identified.
Strengthened battery safety through cooperation. The various partners involved in the study had the common goal of highlighting safety issues relating to maritime batteries.
