Contship Jet sinks off Bulgaria with 421 containers

A ZIM-chartered box ship and all 421 containers are now on the Black Sea floor

The container ship Contship Jet sank around midnight into Thursday 29 October, Novinite reports. She went down about 17 nautical miles off Cape Kaliakra, on Bulgaria’s north-east coast. Three sea drones had hit her the day before. She was carrying 421 containers from Haifa in Israel to Constanta in Romania. About 20 of those boxes fell into the sea after the strike, according to Novinite and Greek City Times. The rest went down with the ship. All 18 crew, 14 Filipino and four Ukrainian, were rescued and taken to Varna.

Our view is simple. The western Black Sea is now a war zone for container shipping, not just for grain bulkers and tankers. This was a laden box ship on a commercial run between Israel and Romania, chartered by ZIM. It was hit inside a NATO member’s economic zone and sank with its cargo. Freight pricing for Constanta, Varna and Burgas has not caught up with that yet. We think it will within weeks.

What happened on 28 October

Bulgaria’s state news agency BTA set out the timeline. At 12:01 the Maritime Rescue Coordination Centre in Constanta got the report of the strike. By 12:13 the crew had abandoned ship. By 12:53 eight sailors were on a Bulgarian Navy boat and ten were still in the ship’s lifeboat. BTA reported that the Defence Ministry identified the attackers as uncrewed surface vessels, meaning small boats with no one aboard, packed with explosives. Three hits were observed. BTA quoted the official line on the crew: “No one was injured, the crew will undergo medical examinations.”

Novinite reports the ship took three breaches on her starboard side. Bulgarian maritime site Maritime.bg released video of a sea drone closing on the ship. Israel Hayom says the footage suggests a drone model not seen in public in the Black Sea before. BTA reports a French maritime patrol aircraft was watching and passed the sighting to the Bulgarian Navy.

The Contship Jet flies the Liberian flag, Novinite and ShipFinder report. Greek City Times says she belongs to the fleet of Contships Management, a Greek manager founded in 2015 by shipowner Nikos Pateras. The Media Line reports she was “chartered by Israel’s ZIM Integrated Shipping Services”. Israel Hayom describes her as ZIM-operated. The Media Line also reports that ZIM said the crew had been rescued and safely evacuated.

Nobody has claimed the attack. Greek City Times, citing Reuters, notes that Ukraine has blamed Russia for earlier attacks of this kind and that Russia denies them. Adm. Emil Eftimov, Bulgaria’s chief of defence, said the attack came from the east. He told reporters, as quoted by Novinite: “We have sufficient information regarding the drones; footage may also emerge soon.”

Why Bulgaria could not stop it

Israel Hayom reports that Eftimov said Bulgaria could not destroy the drones for two reasons. One was the legal limit on what the military can do in the exclusive economic zone (EEZ). The EEZ runs out to 200 miles; a state has economic rights there, but it is not sovereign territory the way the 12-mile territorial sea is. The other reason was severe weather.

That matters for anyone booking cargo. The navy of the coastal state has said, in effect, that it cannot reliably defend ships in the stretch of sea where these attacks are happening. Ships bound for Constanta pass through Bulgarian and Romanian EEZ waters on every call.

The cargo, the claims and the clean-up

The Media Line and Israel Hayom both report that the cargo included lithium-ion batteries, corrosive liquids and acids. The Media Line says the Bulgarian government found no evidence of pollution in preliminary tests. Novinite reports that experts told regional governor Mario Smurkov that no significant harm to the sea or coastline is expected at present.

For cargo owners, the commercial picture is bleak. Every one of the 421 boxes is a total loss. Shippers and their forwarders now face cargo claims on standard marine policies. If the ship’s owners declare general average, cargo interests could be asked to share costs too. General average is an old maritime rule: when costs are incurred to save a voyage, every party with cargo aboard pays a share in proportion to value. Salvage of a ship on the seabed may never be attempted, but the rule still shapes how claims are handled. No general average declaration has been reported.

The bigger question is war cover. Many standard cargo policies include war risk, but the terms differ, and some exclude losses in listed war areas unless the cover is added. Shippers who do not buy their own cover, or who rely on carrier liability alone, may find that a drone strike is not something the carrier has to pay for.

A month of attacks, not a one-off

This was not an isolated strike. Greek City Times, citing AP, says it was the fifth drone attack in Bulgaria’s EEZ this month. Novinite reported on 28 October that four vessels had been struck in Bulgaria’s EEZ since 6 October, with 11 people still missing from one of them.

Insurance Business reported the first of those strikes on 6 October. About 70 nautical miles off the Bulgarian coast near Byala, the general cargo ship Alfa Watan sank and the wheat carrier Able caught fire. A day earlier, the Turkish-owned Royad Mammadov caught fire and sank in Romania’s EEZ. Romanian authorities reported two deaths and suspected, but had not confirmed, a drone strike. On 23 October, Novinite reports, the cargo ship Khoryv was hit by a drone and capsized near Constanta.

The insurance market had already moved before this month’s run of attacks. Insurance Business reports that on 16 September the Joint War Committee, the London market body that lists high-risk areas, extended its Black Sea listed area to the whole sea. Russian and Ukrainian coastal waters were already listed. The territorial waters of Bulgaria, Georgia, Romania and Türkiye were left out, but those run only 12 nautical miles from shore. The Contship Jet was 17 miles out, inside the listed area. As Insurance Business put it, “A listing does not prohibit voyages”. It means insurers can ask for separate war cover and charge an extra premium, set ship by ship.

Insurance Business also cites figures from security firm Ambrey: 45 merchant ships struck outside the previously listed area in the 12 months to 21 September, against none in the 12 months before. Thirty-three of those came in the last three months. Ambrey expects the conditions to last for the rest of 2026.

What happened last time premiums moved

There is a recent precedent for how fast prices react. In December 2025, after attacks on Russia-linked tankers, India Seatrade News reported that Black Sea war-risk premiums, typically 0.25% to 0.3% of a ship’s value, had reached up to 1% for some Ukrainian ports, citing Marsh data reported by other media. It said the cost of covering port calls in the region had more than tripled within days.

That repricing hit tankers and Ukrainian ports. This time the losses are falling on box ships and cargo heading for EU ports. We expect the same pattern: underwriters reprice first, then shipowners pass the cost to charterers, then carriers pass it to shippers as a surcharge.

What forwarders should do now

Our read of what this means for the trade:

  • Check cover today. Confirm that marine cargo policies for Black Sea shipments include war risk, and that the western Black Sea is not excluded as a listed area. Brief clients who rely on carrier liability alone.
  • Declare dangerous goods properly. A ship carrying lithium-ion batteries and acids sank in a war zone. Expect closer scrutiny of DG (dangerous goods) bookings on Black Sea feeders, and possible refusals.
  • Budget for surcharges. War-risk and emergency surcharges are usually announced with short notice. Quotes for Constanta, Varna and Burgas that run past mid-November should carry a clause allowing pass-through.
  • Plan alternatives. Some cargo for Romania and Bulgaria can move via Adriatic or Aegean ports such as Koper or Piraeus and then by rail or truck. That costs more and takes longer, but it may beat an unpriced war risk on the final sea leg.
  • Watch feeder schedules. Feeders, the smaller ships that link hub ports to regional ones, are the most exposed. Their operators may skip calls at short notice if crews or insurers object.

Our prediction: by 30 November, at least one of the ten biggest container lines will announce a war-risk or emergency surcharge on bookings to Constanta, Varna or Burgas. We also expect at least one feeder service to skip or suspend a western Black Sea call in the same window. The sinking of a laden, ZIM-chartered box ship makes both more likely, not less.
