From a safety point of view, the probability of a vessel colliding during an avoidance maneuver by another vessel or drifting due to a propulsion failure can be considered to be significant. The consequences can be significant: loss of human life, perforation of the ship’s tanks causing pollution or even an explosion in the case of an LNG carrier, damage to the impacted wind turbines, rupture of the anchor lines leading to the drift of the platform and a collision of this one against other wind turbines in the park.

The objective of the ColFOWT project is to develop and validate a fast and reliable collision analysis tool, specific for floating offshore wind turbines, based on analytical formulations (super elements derived from plastic limit analysis) coupled with a large rotational floating structure movement solver.

The ColFOWT project was carried out within the framework of the WEAMEC, with funding from the Pays de la Loire Region.
