Guidance mitigates risks from onboard energy storage

DNV Maritime Advisory senior environmental consultant Henrik Helgesen describes the safety risks involved when installing large modules of batteries on ships, and guidance to prevent thermal runaway and onboard fires, during an interview at Riviera’s Maritime Hybrid, Electric & Hydrogen Fuel Cell Conference, which took place in Bergen, Norway.

The European Maritime Safety Agency has provided guidance on battery installations, and it is included in international regulations, class rules and recommendations.

Industry needs an open mind and to share experience and best practices, says Mr Helgesen. He explains the balance required when tackling fires and preventing explosions, such as whether battery rooms should be ventilated and whether batteries should be cooled by water or air.
