A planned offshore wind farm, located between 13 and 22 kilometres from the coast of Fécamp in Normandy, will feature 18 Potain tower cranes equipped with anti-collision systems.
The tower cranes make up the foundation site for the Fécamp wind farm and will be make use of DCS 61-S anti-collision systems. The wind turbines will be connected to gravity foundations installed on the seabed at depths between 25 and 30 meters.
The design and construction works of the 71 concrete gravity structures for the foundation of the offshore wind farm are carried out on the Bougainville shipyard, at the Grand Port Maritime at Le Havre.

Two MDT 349 cranes will move on 120 metres of rail, with 16 MR 608 machines of the same height spread over four parallel tracks.
Because several cranes move on the same track and are placed at the same height, jibs can easily collide. AMCS Technologies was chosen to supply the anti-collision systems, which will play an essential role in ensuring the safety and productivity of the project.
The DCS 61-S detects in real time the risk of collision of all interfering crane components (for example jib on jib, jib on cable).
The device calculates in real time and in 3D the distances between each element of the cranes as well as the speeds and direction of movement on the rails in order to intervene on the control mechanisms of the crane to ensure a slowing down and then a complete immobilisation of the machine at a preset distance from the other machine.
