As ever before much more effective battery packs are mounted in vessels, DNV GL has actually launched a brand-new record on battery security in ships. The record evaluates surge as well as fire dangers in maritime battery setups as well as the performance of fire snuffing out systems in case of a battery fire.
The record has actually been generated in cooperation with MARAD, the Norwegian as well as Danish maritime authorities, battery makers, system integrators, distributors of fire snuffing out systems, shipyards as well as shipowners,
“Batteries onboard ships are both environmentally friendly and cost-effective solutions that we wish to see more of in the future,” claims Lars Alvestad, Acting Director of theNorwegian Maritime Authority “This project has been important in learning the risks of these systems and using the new insight to improve safety requirements.”
A battery fire can generate extremely warm fires, in addition to the threat of surge as a result of gases generated by the battery. DNV GL’s brand-new record offers the outcomes of study on what takes place throughout a fire in a battery area, the launch of gases, as well as the effectiveness of different snuffing out systems in battling the fire as well as stopping surges.
One of one of the most vital searchings for worries air flow systems, which are important to staying clear of a buildup of eruptive gas. The record wraps up that air flow alone will certainly not properly alleviate gas buildup if a considerable part of the battery system stirs 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 as well as Senior Consultant at DNV GL.
The record offers brand-new referrals on air flow systems, based upon a freshly developed design that recognizes the ideal dimension as well as sort of air flow system based upon a vessel’s battery setup. Early fire as well as gas discovery are additionally vital, hence the gas sensing unit ought to lie as near the battery as feasible.
Launched in 2017, the study job makes use of the experience of a large range 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.
