Trainer advises on dangers posed by EV batteries onboard ships

Vessel fires caused by lithium-ion batteries in electric cars are ferocious and extremely difficult to control – something that few shipping companies or their crew know about, according to a leading fuels expert.

Tony In’t Hout, Director at Glasgow-based Stream Marine Training (SMT), believes crew members on container ships carrying electric cars face serious injury or worse unless they understand what causes the batteries to ignite and how to quell the flames.

“In the maritime sector, the issue of electric vehicle batteries being highly flammable when they overheat is often overlooked,” he said. “People don’t realise how dangerous lithium-ion batteries are, so the shipping sector needs courses on how to fight fires – especially as we’ve seen quite a few blazes on ships in recent years caused by vehicle batteries.”

This year, maritime training provider SMT is launching a two-day course, headed by Dutch national In’t Hout, that explores the fire risks to ships carrying lithium-ion batteries. One common cause is the entire battery-package overheating (thermal runway).

On day one of the course, trainees will learn about electric vehicle batteries and other potentially flammable ship industry fuels such as ammonia, hydrogen and methanol. They will also study the carbon footprint of these energy sources. Day two sees the attendees doing practical firefighting sessions at SMT’s training facility in Glasgow, Scotland.

“An aluminium car battery holds eight times the power of a normal one, so it can fuel itself if it catches fire,” said In’t Hout. “Anyone working on ships needs to understand how to deal with that type of situation, which we cover on day two of the course. “Another example is if you have a ferry with a hydrogen truck, an aluminium-battery car and an LNG truck next to each other when a fire breaks out – what should the crew do in that scenario? Most seafarers won’t know because they haven’t had the relevant training.”

Fire outbreaks on vessels caused by electric vehicle batteries have become more commonplace. In May 2019, a fire broke out on the Grande Europa roro, some 25 miles from Palma de Mallorca in the Mediterranean. Just two months earlier, the Grande America roro sank in the Bay of Biscay after igniting. It’s believed that car batteries sparked the fires on both vessels, which were owned by Italian roro operator Grimaldi Group.

More recently, firefighters had to douse flames on Brim, a Norwegian passenger vessel, after its battery ignited on 12 March 2021.The cause was attributed to an overheated battery on the tour boat, which had taken children on an educational trip earlier that day. Fortunately, none of the crew still on the ship when it caught fire were injured.

“If you have a battery car that ignites, you can throw a blanket over it or, as we do in Holland, put it in an open-top container truck filled with water,” In’t Hout said. “The chemical in the battery keeps fuelling itself, so you need water to cool it down. That’s one of the many things we teach on our course.”
