DMA draws up guidelines on large battery installation

The Danish Maritime Authority (DMA) has drawn up guidelines on the installation of large batteries on board ships.

The guidelines have been developed on the basis of the experience gained from the conversion of a number of passenger ships for hybrid operation.

DMA said that it had gained new knowledge on battery safety through a report with focus on risks related to fire. The report outlined different methods of fire extinguishing, along with the effect of ventilation systems in battery compartments in case of fire.

Senior ship surveyor Denis Cederholm-Larsen from the DMA said that “ships of the future need more environment-friendly solutions, but we also have to focus on safety right from the beginning.”

A Joint Development Project started back in 2017 and was coordinated by DNV GL. There was significant cooperation between Norwegian, Danish and American maritime authorities, different battery manufacturers, shipping companies, shipyards, fire extinguisher manufacturers, and system suppliers.

The full report including its results and conclusions can be downloaded from the Danish Maritime Authority’s website or from DNV GL’s website.
