On this episode of the Seatrade Maritime Podcast, Gary Howard speaks with Dr William Moore, Head of Loss Prevention at the American Club, about vessel fires — specifically those involving electric vehicles (EVs). Moore explains the causes of EV fires, and how thermal runaway stems from mechanical, thermal, or electrical abuse of lithium-ion batteries, noting that used EVs can pose higher risks than new units, and that risks increase for states-of-charge over 30%.

While cars with internal combustion engines are far more likely to ignite than EVs, EV fires are tougher to extinguish at sea, Moore explains, as foam and CO₂ are less effective, and the huge volumes of water necessary to control an EV fire can threaten vessel stability while creating toxic runoff.

Recent high-profile car carrier losses often lack definitive root causes, although one confirmed case, Grande Costa d’Avorio in 2023, was not caused by an EV.

With formal IMO rules not expected before 2027, Moore urges ship-specific risk assessments, robust early detection using thermal sensors and cameras, rigorous drills/PPE readiness, smart stowage and access planning, and industry information-sharing to protect crews and assets.
