Norwegian authorities are warning shipowners and also drivers concerning the risks connected with lithium-ion battery systems after a fire and also succeeding gas surge aboard a diesel-electric ferryboat in Norway.

The little fire was reported October 10 in the battery space of the Norled traveler ferryboat MF Ytter øyningen. The ferryboat went back to nurture under its very own power where travelers and also staff were left to land.

Overnight, nonetheless, a severe gas surge shook the battery space triggering substantial damages.

Norwegian transmitting firm NRK reported that twelve firemens were required to the healthcare facility for direct exposure to dangerous gases connected with the batteries.

“The Norwegian Maritime Authority recommends that all shipowners with vessels that have battery installations, carry out a new risk assessment of the dangers connected to possible accumulations of explosive gases during unwanted incidents in the battery systems,” the Norwegian Maritime Authority stated in declaration.

Alternatively, British Columbia- based, Corvus Energy, which provided the ferryboat’s battery system, has issued recommendations to drivers not to cruise without interaction in between the shipboard power monitoring system and also the battery loads, in addition to what to do in instance of a gas launch or “thermal runaway scenario.

Thermal runaway takes place when lithium-ion cell temperature levels go beyond the thermal runaway limit, leading to the abrupt launch of combustible, hazardous gases and also extreme warm that can lead to a surge.

The Norwegian Maritime Authority states the specific series of occasions in the Ytter øyningen fire has actually not been developed, however it will certainly release a Safety Message upgrade when added realities, details and also causal links are made.

All of this has significant effects for Norwegian ferryboat drivers that are significantly counting on hybrid diesel-electric or fully-electric power for vessels running in eco delicate arms and also seaside locations.

The Ytter øyningen was supplied in 2006 and also is furnished with a Corvus Orca Energy storage space system (ESS) with 1989 kWh ability.
