Over the last decades, COWI has gathered broad experience in analysing a wide range of navigational risks. Marine accidents may affect investments and the environment as well as human safety.
Based on AIS ship movement data, we are able to provide a precise analysis of ship-ship collisions, groundings and collisions against fixed structures. Possible risk-control options are identified and assessed with regard to their risk-reducing effect and cost-effectiveness.
A navigational risk analysis provides a sound decision basis for:
- preparing oil spill contingency plans
- establishing design criteria (e.g. for bridges)
- selecting and implementing navigational risk-reducing measures
- planning sea rescue capacities
- assessing future risks, etc.
Optionally, we prepare navigational risk analyses according to IMO’s guidelines for formal safety assessment (FSA).
Spill of oil and chemicals at sea
Oil and chemical spills are among the most severe consequences of accidents at sea. Our analyses includes:
- the probability of accidents
- the probability, type and size of a spill in case of an accident
- the spreading and fate of the spilt substances
- the environmental and socio-economic consequences of the spill
COWI’s environmentalists, biologists and economists are involved in the last two steps of the analysis.
Ship collisions against fixed structures
Ship impacts may pose serious threats to fixed structures in the sea. The frequency, force and energy of colliding ships are a key design parameter for many structures:
- Bridges
- Offshore wind turbines
- Oil platforms and rigs.
Based on ship impact analyses, COWI’s structural engineers assess the potential damage and design the structures accordingly.
