Sweden Arrests Crewmember After Boarding Stateless Cargo Ship ‘Caffa’ in Baltic Waters
Swedish authorities have arrested a crewmember from the stateless cargo ship Caffa after boarding and detaining the vessel in Swedish territorial waters near Trelleborg. The action, carried out by the Swedish Coast Guard in coordination with the Swedish Police Special Intervention Unit, is part of an ongoing investigation into alleged violations of maritime law, including the use of a false flag and unsafe vessel operations.
The Coast Guard, which had been tracking the ship for “some time,” implemented Operation Black Coffee, using a helicopter and a high-speed boat to board the vessel from the stern on 6 March 2026. Authorities detained the ship and took one crewmember ashore on suspicion of committing a serious maritime crime, while the rest of the 11-member crew, primarily Russian nationals, remain under investigation.
According to Daniel Stenling, “It is serious that ships sailing in Swedish waters have deficiencies that pose a threat to maritime safety, shipping lanes, ports, and the environment.” Authorities are examining the ship’s seaworthiness, crew qualifications, and insurance compliance under international maritime regulations.
Built in 1997, the Caffa vessel was previously registered in Russia until 2025 and later claimed registration in Guinea via a Seychelles-based company. Its classification was withdrawn by the Russian Maritime Register of Ships in June 2025. Prior inspections, including a Port State control in Turkey, identified 11 deficiencies ranging from crew working conditions to propulsion and navigation safety.
The Swedish Transport Agency has launched a new Port State inspection to determine whether the vessel should remain detained offshore, which is currently around 5.5 kilometers from Trelleborg. The outcome may lead to fines, legal prosecution, or detention orders, depending on the severity of the maritime safety violations.
The vessel’s suspected involvement in transporting grain from occupied Crimea has also drawn scrutiny from Ukraine, which considers the cargo stolen and seeks to prosecute captains and operators involved. The case highlights ongoing maritime security challenges, enforcement of international shipping law, and the risks posed by stateless vessels in European waters.

Swedish authorities noted that this is the second recent detention of a vessel with regulatory and safety violations, following a December 2025 incident involving a ship linked to the Russian arms industry.
