In partnership with the Norwegian, Danish and also United States maritime authorities, battery producers, system integrators, providers of fire snuffing out systems, shipyards and also shipowners, DNV GL has actually launched a brand-new record on battery security in ships.

The record examines surge and also fire dangers in maritime battery setups and also the performance of fire snuffing out systems in case of a battery fire.

“Batteries onboard ships are both environmentally friendly and cost-effective solutions that we wish to see more of in the future. This project has been important in learning the risks of these systems and using the new insight to improve safety requirements,” claims Lars Alvestad, Acting Director of the Norwegian Maritime Authority.

A battery fire can create extremely warm fires, in addition to the threat of surge because of gases generated by the battery. DNV GL’s brand-new record offers the outcomes of study on what occurs throughout a fire in a battery area, the launch of gases, and also the effectiveness of different snuffing out systems in battling the fire and also stopping surges. One of one of the most essential searchings for problems air flow systems, which are essential to staying clear of a build-up of eruptive gas. The record wraps up that air flow alone will certainly not effectively alleviate gas build-up if a considerable section of the battery system fires up.

“In addition to fire suppression and ventilation, the battery design must have preventative safety barriers so that the fire and gas emissions are limited to as small a part of the battery system as possible,” claims Henrik Helgesen, Project Manager for the study job and also Senior Consultant at DNV GL.

The record supplies brand-new referrals on air flow systems, based upon a freshly developed version which recognizes the proper dimension and also kind of air flow system based upon a vessel’s battery setup. Early fire and also gas discovery are additionally crucial, implying that the gas sensing unit need to lie as near the battery as feasible.

Launched in 2017, the study job makes use of the experience of a variety of maritime stakeholders. “It is very important for us to work closely with all parts of the industry and understand the full picture as we work to promote safety in our regulatory development work,” claims Denis Cederholm-Larsen, Senior Ship Surveyor at the Danish Maritime Authority.
