Crowley continues to work closely with U.K. agencies to support response operations resulting from container ship Solong striking the Crowley-managed tanker Stena Immaculate while at anchor on Monday, March 10.
A fire onboard the Stena Immaculate has ceased with no visible signs of smoke or flame after reviews Wednesday. Crowley continues to assist response efforts led by the U.K. Maritime and Coastguard Agency (MCA). The vessel is stable, remains securely anchored and is being monitored via a salvage vessel by Crowley representatives and partners as well as government authorities.
Initial third-party salvage operations for the Stena Immaculate have begun to assess the vessel exterior and indicate no ongoing release of cargo product to the water and no sheen on the water. The MCA also indicated on Wednesday there have been no further reports of pollution to the sea from Stena Immaculate.
Crowley continues to support government agencies monitoring environmental conditions. Salvage activities onboard will begin as soon as safety and weather allow.
Until salvage teams can go aboard the ship, it remains unclear what volume of Jet A1 fuel may have been released as a result of the incident. Of the 16 cargo holds, at least one was impacted.
Our priorities continue to be carrying out the incident response and mitigating environmental threats, while fully supporting the health and wellbeing of our mariners in Grimsby. Authorities also continue to investigate the cause of the incident and its impacts, and we defer to them for any related questions.

Crowley continues to work closely with U.K. agencies to support the incident response, salvage and environmental impact mitigation operations resulting from container ship Solong striking the Crowley-managed tanker Stena Immaculate while at anchor on Monday, March 10.
A fire onboard the Stena Immaculate has greatly diminished with no visible flames. Crowley is continuing to assist response efforts led by the U.K. Maritime and Coastguard Agency (MCA). The vessel is stationary at anchor and being monitored by Crowley representatives, partners and government authorities, and we are working alongside partners during initial salvage activities.
In the meantime, we are prioritizing supporting the health and wellbeing of our mariners in Grimsby and the response effort to mitigate environmental threats.
It remains uncertain at this time what volume of fuel may have been released as a result of the incident, but initial review shows impacts have been limited due to exposure to the fire and evaporation of the Jet A1 fuel. In addition, U.K agencies are closely monitoring air quality and any possible public health impacts resulting onshore. Both are currently measuring low or within normal levels.
Authorities continue to investigate the cause of the incident and its impacts, and we defer to them for any question about the cause. The individual arrested by local police is not a member of the Crowley crew.
Update 2: March 10, 2025; 1700EDT
At approximately 10 a.m. UTC/5 a.m. EDT on March 10, 2025, while stationary and anchored off the North Sea coast near Hull, United Kingdom, the Crowley-managed tanker Stena Immaculate was struck on its port side by the container ship Solong. As a result, at least one cargo tank containing Jet-A1 fuel was ruptured.
Crowley is working closely with response agencies including the HM Coastguard to secure the vessel in a restricted safety area and initiate spill containment response. All 23 Crowley mariners that were on board are safe and accounted for with no reported injuries at this time.
"As with all our operations, Crowley’s priority is to protect the safety of mariners, and the environment. We greatly appreciate the quick actions and support of the U.K. authorities, rescue workers and others to today’s incident and remain committed to working with them on the continued response efforts," said Cal Hayden, vice president, Crowley global ship management.
The Stena Immaculate is managed by Crowley through a joint venture with owner Stena Bulk USA. In 2023, the tanker was selected by the U.S. Maritime Administration (MARAD) to serve in its Tanker Security Program. While under charter on this voyage for the Military Sealift Command, the tanker was anchored while it awaited berth availability at the Port of Killingholme, where it was due to make a standard delivery of fuel as part of a routine service under this program when it was struck.
At this stage, it is unclear what volume of fuel may have been released as a result of the incident. At the time it was struck, the 183-meter (596-foot) Stena Immaculate was carrying 220,000 barrels of jet fuel in 16 segregated cargo tanks. Crowley is supporting the relevant authorities in the UK who are investigating the incident and will defer to them for any further questions on potential cause.
Crowley will also provide further updates on official company social media channels.

At approximately 10 a.m. UTC/ 5 a.m. EST on March 10, 2025, while anchored off the North Sea coast near Hull, United Kingdom, the Crowley-managed tanker Stena Immaculate was struck by the container ship Solong.
The Stena Immaculate sustained a ruptured cargo tank containing Jet-A1 fuel due to the allision. A fire occurred as a result of the allision, and fuel was reported released. The Stena Immaculate crew abandoned the vessel following multiple explosions onboard. All Crowley mariners are safe and fully accounted for.
Crowley immediately initiated its emergency vessel response plan and is actively working with public agencies to contain the fire and secure the vessel.
Our first priority is the safety of the people and environment. We will provide more updates as information becomes available.
