Why Do Car-Carrier Fires Go Without a Report?

The flag state must investigate but has no deadline. Sincerity Ace's report is still unpublished, and 204 of 526 recent reports never reached IMO.
Because the duty to investigate falls on the flag state and nothing sets a deadline for the report. IMO's Casualty Investigation Code, mandatory since 1 January 2010, requires a safety investigation into every very serious casualty and a final report to IMO, but no date. Panama investigated the 2018 Sincerity Ace fire and has not released a report. Across shipping, 204 of 526 very serious casualties in 2017–2020 produced no report at IMO.
That gap matters more for car carriers than for most ship types. Their fires are rare, costly and hard to explain, and the hull often sinks before anyone can examine it. An investigation report is the one public document that can say what started a fire, what the crew saw and which defence failed. Without it, owners, insurers and regulators are left arguing from press reports and court files.
Who has to investigate a car-carrier fire?
The flag state, unless it agrees otherwise with another affected state. The Casualty Investigation Code, adopted by Resolution MSC.255(84) on 16 May 2008 and made mandatory through SOLAS regulation XI-1/6, defines a very serious marine casualty as one involving the total loss of the ship, a death or severe damage to the environment. Chapter 6 says a safety investigation must be conducted into every one, and that the flag state is responsible for making sure it is carried out and completed.
Other states can take part or take the lead. The Code lists "substantially interested" states: the coastal state, any state whose environment or nationals were harmed, and any state holding important information. Where a casualty happens in a state's territorial sea, the flag and coastal states must consult on who leads. On the high seas or in an exclusive economic zone, consultation is required where more than one flag state is involved. In practice, the reports that do appear on car-carrier fires often come from a coastal state's investigator, not the flag's.
What the Code requires, and what it doesn't
It requires a report but not a date. Chapter 14 says the investigating state shall submit the final report on every very serious casualty to IMO, and make it available to the public and the shipping industry. There is no deadline in the mandatory text and no sanction for a report that never comes. The European Union goes further for its own members: Directive 2009/18/EC requires member states' investigation bodies to publish a report within 12 months of a casualty, or an interim report if the final one is not ready.
What the car-carrier record looks like
Reports come mostly from strong coastal investigators; fires far offshore under open registries often produce none. The pattern in the cases this site has covered:
- Höegh Xiamen (2020, at a Jacksonville berth): the US NTSB published Marine Accident Report MAR-21/04 and named a probable cause.
- Grande America (2019, Bay of Biscay): France's BEAmer investigated and published, though it could not fix where the fire began.
- Euroferry Olympia (2022, off Corfu): Greece's HBMCI led and published an interim report in June 2023.
- Fremantle Highway (2023, off the Dutch coast, Panama flag): the Dutch Safety Board reported in May 2025, on the rescue rather than the cause.
- Sincerity Ace (2018, north Pacific, Panama flag, five crew dead): Panama investigated; no report has been released.
- Felicity Ace (2022, off the Azores, Panama flag) and Morning Midas (2025, north Pacific, Liberia flag): no published investigation report was found for either.
Why the missing reports cost the industry
Because every unexplained fire becomes an argument instead of a lesson. Shipping organisations raised this at IMO in 2014: ICS and the ITF told the Maritime Safety Committee that missing reports frustrated operators trying to learn from casualties. Lloyd's List reported in 2024 that report submission had improved by 12% over four years, but that member states still routinely failed to publish. For car carriers the cost shows up in three places.
First, prevention: the industry is debating whether EVs, used cars or ship systems drive these fires, and each missing report removes a data point. Second, recovery: when nobody can prove which vehicle started a fire, subrogation fails, as the Stuttgart court found in the claim against Porsche over Felicity Ace in May 2026. Third, pricing: underwriters asked to price EV-heavy cargo without causal evidence price the uncertainty instead.
What owners and underwriters can do
Treat the evidence as yours to keep, not the flag state's to publish. Owners can preserve their own records of a casualty, from alarm logs and loading data to CCTV and VDR data where it can be recovered, rather than relying on a report that may never come. When choosing a flag, they can ask how its investigation body handles very serious casualties, and how many of its reports reach IMO. Underwriters and P&I clubs can ask the same questions at renewal and support coastal-state investigations when a casualty happens in their waters. None of this replaces a public report. It narrows how much depends on one.
How RoRoSAFE helps
When a car carrier sinks mid-ocean, the deck's own record is often the only evidence of where the fire started. RoRoSAFE puts infrared thermal and battery-vent gas sensing under each parked vehicle, with alerts to the bridge and shore that name the deck and bay. Its tamper-evident logs and export-ready reports give owners, insurers and investigators a time-stamped account to work from. It complements SOLAS detection and holds no class type approval yet.

Questions, answered
Who investigates a fire on a car carrier?+
The flag state is responsible under IMO's Casualty Investigation Code, which has been mandatory through SOLAS since 2010. For a very serious casualty, meaning a total loss, a death or severe pollution, an investigation is required. Coastal states and other substantially interested states can take part or lead by agreement, and the published reports on car-carrier fires often come from coastal investigators such as the NTSB or the Dutch Safety Board.
Is there a deadline for a ship casualty investigation report?+
Not in IMO's mandatory rules. The Casualty Investigation Code requires a final report on every very serious casualty to be sent to IMO and made public, but sets no date. In the EU, Directive 2009/18/EC requires member states' investigation bodies to publish a final report within 12 months of the casualty, or an interim report if the final one is not ready.
Why was there no report on the Sincerity Ace fire?+
Panama, the flag state, investigated the December 2018 fire, in which five of 21 crew died, but has not released a report. Nothing in IMO's rules sets a deadline for it. Panama-flagged ships accounted for 13 missing very serious casualty reports in 2017–2020, according to Lloyd's List analysis of IMO data.
How often do flag states fail to publish casualty reports?+
Often. Lloyd's List found that for 526 very serious casualties between 2017 and 2020, only 322 investigation reports had reached IMO's GISIS database, leaving about 39% unreported. It later reported a 12% improvement in submissions over four years, but member states still routinely fail to publish investigations.

Sincerity Ace: The Fire With No Public Report
Five crew died when the Sincerity Ace burned 1,800 nm off Oahu in 2018. Panama investigated, the cause stayed unknown, and no report was published.

Why Felicity Ace's Cause Was Never Proven
Because the evidence burned, sank in 3,000 m of water and was never recorded. Every car-deck fire with a proven cause stayed afloat; no deep-sea loss did.

Subrogation and the Cargo-Manufacturer Question
Can insurers recover an EV-fire loss from the carmaker? Stuttgart said no in May 2026: nobody could prove which car started the Felicity Ace fire.

Höegh Xiamen: Anatomy of a Total Loss
The NTSB traced a $40M car-carrier total loss to one used vehicle's improperly disconnected battery — and the oversight that let 2,420 cars load unchecked.
Fremantle Highway — Anatomy of a Late Rescue
The Dutch Safety Board's 2025 report on the Fremantle Highway blamed the rescue, not the cars: seven crew jumped ~30 m and one died.
Morning Midas: Anatomy of a Total Loss
The Morning Midas sank in June 2025 — the ninth car-carrier total loss in a decade — and its claim split across hull, P&I, and cargo underwriters.
