In brief
A container ship named Contship Jet was struck by three maritime drones southeast of Shabla and later sank around midnight. All 18 crew members were rescued and taken to Varna. Bulgarian authorities report no visible contamination from the ship’s cargo of lithium‑ion batteries and light fuel oil, but plan further seawater sampling along the Black Sea coast to confirm water quality.
On Wednesday, October 28, 2026, a Greek‑managed container vessel named Contship Jet was struck by three maritime drones approximately 21 nautical miles southeast of Shabla, near Cape Kaliakra. The hit caused a catastrophic flood that led the ship to sink around midnight in Bulgarian territorial waters. All 18 crew members – 14 Filipinos and four Ukrainians – were rescued by local authorities and transported to Varna before the vessel fully submerged.
The ship was carrying a cargo of 421 containers, including lithium‑ion batteries and 421 t of light fuel oil classified as gas oil. According to the Defense Ministry, the fuel evaporates relatively quickly if released into the sea and is not expected to reach the Bulgarian shoreline. Maritime Administration teams inspected the wreck and reported that no significant adverse effects on the marine environment or coastline were anticipated at the time of the assessment.
The Maritime Administration Executive Agency and the Varna Regional Administration confirmed that the ship’s sinking was the fifth drone attack on foreign vessels within Bulgaria’s exclusive economic zone since the beginning of October. Despite the lack of immediate visual pollution, the authorities are taking a cautious approach to environmental monitoring.
Defence Minister Dimitar Stoyanov told reporters at a regional security meeting, “A container ship was hit…with three naval drones, approximately 21 miles southeast of Shabla.” The statement underscored the severity of the incident and the need for continued vigilance against drone attacks in the area.
In response to the incident, teams from the Defence Ministry collected seawater samples from two sites in Bulgarian territorial waters. They found no obvious signs of pollution. However, additional sampling is planned by the Black Sea Basin Directorate and the Executive Environment Agency for Thursday.
Jury of five coastal locations – Durankulak, Shabla, Cape Kaliakra, Byala and Sozopol – will receive seawater samples planned for the next day. The samples will be tested for petroleum products, polychlorinated biphenyls, metals and other physicochemical indicators of water quality. The Executive Environment Agency has set up regional laboratories in Varna and Burgas to analyze the results.
The Environment and Water Ministry has announced that the sampling will also cover the area surrounding the sunken vessel. Officials say the aim is to detect any changes in seawater quality that are not evident through visual inspection alone, ensuring a thorough protection of the Black Sea ecosystem.
The Maritime Administration’s preliminary analysis concluded that the gas oil was not expected to reach the coast, and that the observers noted “no visible signs of pollution.” They emphasized that ocean monitoring will continue, and that the responsible institutions are ready to act should any risk or change arise.
The two assessments – one by Maritime Administration and one by the Defence Ministry – both point to a minimal immediate environmental impact. Nevertheless, the planned extensive seawater sampling underscores Bulgaria’s commitment to monitoring potential delayed effects from the sunk ship’s cargo.
Results from the seawater tests will be made public once the analyses are complete. The authorities have reiterated that they remain alert to any developments and will coordinate closely with all competent state institutions to safeguard marine and coastal environments against any future risks.
