A Vehicle-Carrier Fire Every 37 Days
Allianz's Safety & Shipping Review 2026 records a vehicle-carrier fire every 37 days and warns the EV fire risk at sea is 'not under control'.
Allianz's Safety & Shipping Review 2026 puts a number on it: a fire on a vehicle carrier roughly every 37 days, against a container-ship fire every 17. Fires on large vessels topped 200 in 2025 — the second-highest annual total of the past decade, with at least nine total losses. And Allianz's marine risk lead is blunt about the cause that worries underwriters most: the EV fire risk at sea is, in his words, 'not under control.'
What the 2026 review actually counted
Fire is no longer a tail risk on the data — it is a recurring event. Allianz logged more than 200 fire incidents on large vessels in 2025, down from 2024 but still the second-highest of the decade, with at least nine total losses. Roughly 30% of those fires were on container, general-cargo or ro-ro vessels. Reduced to a cadence, that is a container-ship fire about every 17 days and a vehicle-carrier fire about every 37 — frequencies, not freak events.
Why batteries are the trend line
Because the cargo is scaling faster than the controls around it. Allianz notes lithium-ion battery shipments are already roughly six times higher than five years ago and are projected to double again by 2030, with the battery market forecast near US$322 billion by then. Misdeclared and improperly packed cargo remains a leading fire cause — about a quarter of cargo-related incidents — and while that figure is anchored in the container trade, the lesson crosses straight to a vehicle deck: you cannot fight what you did not know you were carrying.
'Not under control' — the underwriter's words
"While regulatory changes are in progress, we cannot say this is a risk that is under control. This is still very much a live issue and one that will only get worse with electrification."— Capt. Rahul Khanna, Global Head of Marine Risk Consulting, Allianz Commercial
When the marine market's own risk lead says a hazard is not under control, that judgement does not stay in a report — it migrates into renewal questionnaires, deductibles and survey requirements. A vehicle-carrier fire every 37 days is the kind of frequency that reprices a book, and owners answer for it whether or not a regulation has caught up.
The 2028 gap
The binding rules trail the cargo by years. Mandatory IMO regulation specific to electric vehicles does not enter force until 1 January 2028, and the SOLAS/FSS Code detection amendments phase in across new builds in 2026 and existing ships by the first survey on or after 1 January 2028. That leaves 2026–27 as an exposed window: the EVs are loading now, the fires are happening now, and the prescriptive requirement that would mandate earlier vehicle-level detection is not yet in force. In that gap, the mitigation is the operator's to choose, not the regulator's to compel.
What owners can do inside the gap
Shorten the interval between a fault and a response, because that interval decides whether a single faulting vehicle becomes a constructive total loss. Conventional smoke and heat detection confirms a fire that already exists; an early per-vehicle thermal layer flags the heat rise before smoke, buying the response time the 37-day cadence keeps proving owners need. It is also an auditable risk feature an underwriter can credit now — the one move that pays in both the safety case and the renewal, ahead of the 2028 deadline rather than because of it.
How RoRoSAFE helps
A fire every 37 days is a frequency no owner can plan around, but the size of each loss still depends on how early the crew knows. RoRoSAFE puts a thermal and gas sensor cell under each parked vehicle, so a battery that starts off-gassing is flagged to the bridge and shore before there is visible smoke. That is the part of 'not under control' an owner can act on inside the 2028 gap, without waiting for the rules.

Questions, answered
How often do vehicle carriers catch fire, according to Allianz?+
Allianz's Safety & Shipping Review 2026 records a fire on a vehicle carrier roughly every 37 days, alongside a container-ship fire about every 17 days. Fires on large vessels topped 200 in 2025 — the second-highest annual total of the past decade — with at least nine total losses, around 30% of them on container, cargo or ro-ro vessels.
Why does Allianz say the EV fire risk is 'not under control'?+
Because the cargo is outpacing the controls. Allianz's marine risk lead, Capt. Rahul Khanna, said that while regulatory changes are in progress, the risk cannot be called under control and will worsen with electrification. Lithium-ion battery shipments are already about six times higher than five years ago and are projected to double again by 2030.
What is the 2028 regulatory gap?+
Mandatory IMO regulation specific to electric vehicles does not enter force until 1 January 2028, and the SOLAS/FSS detection amendments phase in across 2026 (new builds) and 2028 (existing ships). So 2026–27 is an exposed window: EVs are loading and fires are happening, but the prescriptive rule requiring earlier vehicle-level detection is not yet binding.
What can owners do before the 2028 rules take effect?+
Add an early per-vehicle detection layer now. Conventional smoke and heat detection confirms a fire that already exists, whereas a thermal early layer flags the heat rise before smoke and shortens the fault-to-response interval. It is deployable in 2026, auditable for underwriters, and does not require waiting for the 2028 regulation to make it mandatory.

Why Fire Detection Is Difficult on Ro-Ro Vehicle Decks
Ventilation dilutes the smoke, cargo hides the source, loading mutes the detectors, and a fire can spread car to car in about 20 minutes. Here is why.

Do Pure-EV Car Carriers Change the Risk?
Carmakers like BYD now run near-fully-electric car carriers — BYD Shenzhen holds 9,200 vehicles. That concentrates the fire load, but also the knowledge.
Does Car-Carrier Fire Compliance Arrive in 2027?
No. 2027 holds no entry-into-force date. The calendar is 2026 (new passenger ships), 2028 (existing ro-pax) and 2032 at the earliest for PCTCs.

Does EV-Ready Tonnage Earn a Premium?
Not yet. A 30-year-old PCTC just sold for $39.5m and rates are at records. Safety spec is priced as avoided detention, not as a hire premium.
