As ever before a lot more effective battery packs are mounted in vessels, DNV GL has actually launched a brand-new record on battery security in ships. The record examines surge as well as fire threats in maritime battery installments as well as the efficiency of fire snuffing out systems in case of a battery fire.
The record has actually been generated in partnership with MARAD, the Norwegian as well as Danish maritime authorities, battery producers, 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 create really 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 research study on what occurs throughout a fire in a battery area, the launch of gases, as well as the efficiency of different snuffing out systems in dealing with the fire as well as protecting against surges.
One of one of the most crucial searchings for worries air flow systems, which are essential to preventing a buildup of eruptive gas. The record wraps up that air flow alone will certainly not appropriately alleviate gas buildup if a considerable section of the battery system sparks.
“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 research study task as well as Senior Consultant at DNV GL.
The record offers brand-new referrals on air flow systems, based upon a freshly produced version that recognizes the proper dimension as well as sort of air flow system based upon a vessel’s battery installment. Early fire as well as gas discovery are additionally crucial, therefore the gas sensing unit ought to lie as near to the battery as feasible.
Launched in 2017, the research study task makes use of the experience of a wide 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.
