Ship collision
General information
Driven by market needs ships and offshore structures vary in form, size, speed and operational area. Consequently most of recent structures are one-offs without any experience record. Therefore, assurance of sufficient ultimate strength of these structures forms a challenge for designers and a concern for operators.

Services & Activities
MARIN can help designers and operators to improve the safety at sea and in harbours. Our Hydro-Structural Services (HSS) , part of the Trials & Monitoring department can advice on structural strength including collision and grounding. The Seakeeping department can assist using dedicated model test, whereas the Nautical Training Center (MSCN) can perform safety studies.
With respect to ultimate limit states we can:

With respect to ultimate limit states we can:
- Determine extreme hydro-dynamic loading which is needed in the design stage. This includes extreme sectional forces, motion induced accelerations and wave pressures
- Estimate ultimate strength of structures and their components
- Advice on safety factors
- Control extreme loading during operation by monitoring systems
- Provide decision support towards avoidance of extreme conditions
- Carry out safety studies involving Ultimate Limit States (ULS), like collision or grounding of ships
Facilities & Tools
Our service is facilitated by:
Our service is facilitated by:
- Model testing in the Seakeeping & Manoeuvring Basin using segmented models that allow, among others, for measurement of extreme sectional forces
- Numerical calculations of ultimate strength using hydro-structural software., e.g. Marcol
- Numerical tools such as Samson to perform safety studies
- Monitoring systems to control extreme conditions
- On board advisory systems
