Incident Details:

  • Time and Location: The collision happened around 9:50 AM local time in the Humber Estuary.
  • Vessels Involved:

- Stena Immaculate: An oil tanker carrying approximately 18,000 tons of jet fuel,
operating under a short-term charter to the US Navy.

- Solong: A cargo ship transporting 15 containers of sodium cyanide, a highly toxic
chemical, and an unspecified quantity of alcohol.

Consequences of the Collision:

  • Fires and Explosions: The impact resulted in both vessels catching fire, with the Stena
    Immaculate experiencing multiple explosions due to ruptured cargo tanks.
  • Crew Evacuation: A total of 37 crew members from both ships were evacuated. One individual
    was hospitalized, and one crew member from the Solong remains missing.
  • Environmental Concerns: There is significant worry about potential environmental damage.
    The Stena Immaculate's jet fuel spill poses a risk to marine life, and the Solong's cargo of sodium
    cyanide could have catastrophic ecological impacts if released into the sea.

  • Environmental Monitoring: The Maritime and Coastguard Agency is assessing the
    environmental impact, focusing on the potential spread of jet fuel and the risk posed by the sodium cyanide cargo.

This incident highlights the challenges faced in maritime safety and environmental protection, especially when hazardous materials are involved. Authorities continue to work diligently to manage the situation and mitigate potential risks.
