What is being bought
The MAIB conducted market analysis for the assessment of the navigational risk assessment for a defined area of the North Sea region including the location of the collision between the Portugal registered containership Solong and the USA registered oil/chemical tanker Stena Immaculate on 10 March 2025. The research concluded that one supplier could provide the service. The scope of this project is to identify the navigational risk at the accident location and proximate sea areas.
