What we know about the North Sea tanker collision

A cargo ship reportedly carrying sodium cyanide collided with a tanker chartered by the US military off the British coast, resulting in jet fuel catching fire and leaking into the North Sea. More than 30 people were injured, but all crew members from the tanker have been rescued.

Collision Details

The incident involved the tanker 'Stena Immaculate', which was anchored about 10 miles (16 kilometers) off the port of Hull when it was struck by the container vessel 'Solong', according to Crowley Maritime, the US shipping firm managing the tanker. The alarm was raised at 09:48 GMT. The 'Solong' was reported to be carrying 15 containers of sodium cyanide, a flammable substance.

The collision caused a massive fire that engulfed both vessels. Crowley Maritime confirmed that the tanker was transporting jet-A1 fuel and that it had been chartered by the US Defense Department. The crew of the 'Stena Immaculate' abandoned the vessel following multiple explosions.

Approximately 32 people were rescued and brought ashore on three vessels, as noted by Grimsby port director Martyn Boyers. Stena Bulk, the Swedish company that owns the tanker, reported that all crew members were safe.

The 'Solong', a 140-meter (460 feet) Portuguese-flagged vessel owned by German company Reederei Koepping, was en route from Grangemouth in Scotland to Rotterdam, Netherlands.

Rescue and Environmental Response

Images from the scene revealed flames and thick black smoke rising from the wreckage of both ships. The UK Coastguard coordinated a rescue and emergency pollution operation after Crowley Maritime reported that the impact had ruptured the tanker. The Royal National Lifeboat Institution (RNLI) also responded, confirming reports of fires aboard both vessels.

A team from the Marine Accident Investigation Branch was already on-site "gathering evidence" and assessing the situation. Rescue efforts involved planes, lifeboats from coastal stations, and nearby vessels.

Traffic Suspension

Associated British Ports (ABP), which operates the ports in Hull and Immingham, announced a halt to all vessel movements in the Humber estuary leading to the North Sea.

Historical Context

While the North Sea features busy shipping lanes, accidents are relatively uncommon. In October 2023, a collision between two cargo ships near Germany's Heligoland islands resulted in three fatalities. Additionally, a major oil spill occurred in January 1993 when the Liberian tanker 'Braer' ran aground near Scotland, releasing 84,500 tonnes of crude oil.

Investigative Insights

David McFarlane from Maritime Risk and Safety consultancy noted that there are between 200 to 300 ship collisions worldwide each year, with most being minor incidents. He emphasized the importance of maintaining a proper lookout, suggesting that the collision could have been prevented. Investigators will examine the video data recorders—akin to an aircraft's black box—on both vessels, which will provide information on radar data and bridge communications.
