A major maritime emergency is unfolding in the North Sea after a dramatic collision between two commercial vessels led to a firestorm and environmental threat just off the East Yorkshire coast.
On 10 March 2025, the Portuguese-registered cargo ship Solong collided with the US-flagged oil tanker Stena Immaculate, setting the container vessel ablaze and causing widespread concern over the escalating situation at sea.
The RNLI safely evacuated 36 crew members—23 from the Stena Immaculate and 13 from the Solong. However, one Solong crew member remains missing, and search operations were suspended late on 10 March due to worsening conditions.
Toxic Cargo Raises Stakes
Ship owner Ernst Russ confirmed that the Solong was carrying 15 empty containers that previously held sodium cyanide—a highly toxic chemical compound. Although empty, the containers’ presence has alarmed environmental groups.

Officials emphasize that there’s no immediate chemical risk, but the containers’ proximity to open flames and turbulent waters adds to the growing list of concerns.
Environmental Threat Escalates
With jet fuel leaking into the sea and the Solong drifting toward the ecologically sensitive Humber Estuary and Flamborough Cliffs, conservationists are on high alert. These waters are home to puffins, gannets, seals, and other protected species.
Greenpeace UK called for immediate containment measures, warning that while jet fuel evaporates faster than crude oil, it still poses a significant threat to marine ecosystems. Booms and dispersants are being prepared, but deployment is complicated by the fire and adverse sea conditions.
Investigation Launched
The Marine Accident Investigation Branch (MAIB) has opened a formal inquiry from its base in Grimsby, probing how the Solong struck a stationary tanker despite modern navigation systems and AIS warnings. Heavy fog was reported in the area, but investigators say this alone may not explain the catastrophic failure.

Authorities from the UK, US, and Portugal are jointly involved, while Ernst Russ continues working to stop the Solong’s drift and douse the fire.
Shipping Disruption and Strategic Implications
The Humber Estuary has been temporarily closed to commercial traffic, halting operations at nearby ports as crisis teams work to stabilise the situation.
The incident also underscores broader concerns. The Stena Immaculate is linked to the US Navy’s Military Sealift Command, raising questions about security in strategic maritime lanes. The US Navy has reported no operational disruption, but observers warn that the event highlights growing risks in crowded waters.
Local Impact and Industry Repercussions
Communities from Grimsby to Hull are monitoring developments closely, as the burning Solong drifts perilously closer to the coastline. Residents reported hearing the initial blast, described by Port of Grimsby East’s Martyn Boyers as “overwhelming.”
Maritime insurers, including Skuld, are bracing for multi-million-pound claims, as assessments of structural damage, fuel spillage, and cargo loss continue.
What Happens Next
Efforts to contain the fire and halt the Solong’s drift are ongoing. The UK government has activated emergency maritime protocols, and further updates are expected as recovery crews attempt to regain control of the vessel.
