MV Delphine — Anatomy of a Contained Loss

By Commercial · June 30, 2026 · 7 min read

CO2 suppression worked as designed aboard the MV Delphine at Zeebrugge — yet a vehicle fire still consumed almost a full deck of ~100 cars first.

On 16 April 2025 a fire broke out on the third cargo deck of the MV Delphine — CLdN's 8,000-lane-metre short-sea ro/ro — while it lay alongside at Zeebrugge. The CO2 flooding system was activated and worked as designed; the fire was contained without injury. Almost the entire deck, around 100 vehicles, was already gone. CO2 succeeding and a deck of cars burning are not a contradiction — they are what late detection looks like.

What was lost

A near-complete deck of vehicles — on a vessel that survived and sailed again.

  • The fire started on the third deck, which was carrying 60 electric vehicles and 40 conventional cars — about 100 units.
  • Reported losses ran from 60–70 vehicles (Maritime Executive) to around 100 — close to the entire affected deck (WorldCargo News). Even the count was never pinned down precisely.
  • The vessel itself was not lost: the Delphine returned to service at a reduced 6,000 lane metres (down from 8,000), completing a first post-incident sailing between Zeebrugge and Killingholme while repairs continued.
  • No injuries. The fire was fought alongside, with four tugs playing water cannon on the hull to cool it.

What the investigation found

A vehicle started it — but, unusually, not the electric one everyone first assumed. CLdN's May 2025 update stated the company was "discounting a full electric (BEV) vehicle as the origin of the incident," while confirming the fire originated from a vehicle unit loaded aboard. No specific cause was publicly confirmed.

That ambiguity is the forensic signature of these fires: the data needed to name the origin vehicle is rarely captured before ignition. The Delphine is the mirror image of Felicity Ace — there a BEV could not be excluded; here a BEV was excluded — and in both the question stayed open, because nothing was monitoring individual vehicles in the minutes before the fire took hold. When even the number of cars destroyed is reported as a range, the absence of per-vehicle data is doing the work.

Why CO2 'working' still cost a deck

CO2 limits the fire load already burning when it floods; it does not reach back to before ignition. By the time smoke detection tripped and the deck was sealed, the fire among tightly stowed cars on the third deck was established. CO2 then did exactly its job — contained the space, no spread, no injuries — but containment at the smoke stage means the cars already alight are written off. On the Delphine that was most of a deck.

A 'successful' CO2 activation and a near-total deck loss are the same event seen from two angles. The variable that decides how many cars survive is not whether CO2 works — it is how early the fire was found.

What a port had that the open ocean doesn't

Zeebrugge gave the Delphine what Morning Midas never had 300 nautical miles off Alaska: shore-side firefighting, four tugs with water cannon, a quayside to evacuate to, and no need to abandon ship. That is much of why the Delphine is a contained loss and Morning Midas a total one. But shore support changed the back half of the timeline, not the front: the fire was still found at the smoke stage, after ignition. Port proximity limits a fire CO2 cannot fully prevent; it does not wind the clock back to before the cargo lit.

What it means for owners, class, and underwriters

For owners, the Delphine reframes "the suppression worked" as an incomplete win — a deck of cars is still a claim, a repair, and months at reduced capacity. For class and underwriters, it is a clean datapoint that the expensive variable is detection lead time, not suppression hardware: two near-identical fires — Delphine and Morning Midas — diverged on shore access and fire load, not on whether CO2 functioned. Per-vehicle detection that flags a unit before the smoke stage is what would have changed the cargo count, and that is increasingly an underwriting input rather than a safety nicety.

Frequently asked

Questions, answered

Was the MV Delphine fire caused by an electric vehicle?+

Not according to CLdN. Its May 2025 update said the company was "discounting a full electric (BEV) vehicle as the origin of the incident," while confirming a loaded vehicle unit was the source. Early reports had assumed an EV because 60 of the 100 cars on the affected deck were electric, but no specific cause was publicly confirmed. It is the mirror image of Felicity Ace, where a BEV could not be ruled out.

If the CO2 system worked, why were so many cars lost?+

CO2 contains the fire load already burning when it floods the space; it cannot reverse losses that occurred before it activated. On the Delphine the system tripped at the smoke stage, by which point the fire among tightly stowed cars on the third deck was established. CO2 then contained it with no spread and no injuries — but around 100 vehicles, close to the whole deck, were already gone.

Why is the Delphine a contained loss when Morning Midas was a total loss?+

Shore access. The Delphine burned alongside at Zeebrugge, with four tugs playing water cannon on the hull and a quay to evacuate to; Morning Midas burned 300 nautical miles off Alaska and had to be abandoned. Port proximity changed the back half of the timeline. The front half — a fire found only at the smoke stage, after ignition — was identical.

What is the detection lesson from the Delphine?+

That detection lead time, not suppression hardware, decides the cargo count. CO2 functioned perfectly and a deck still burned, because the fire was found late. A system that flags a single vehicle's pre-ignition signature — before visible smoke — shrinks the window in which one fault becomes a near-total deck loss. That lead time is increasingly an underwriting input, not just a safety feature.
