Seajacks is the main installation contractor for the construction of Meerwind, a 288MW wind farm development located in the Exclusive Economic Zone region of the German North Sea. When fully operational, the eighty turbine project will produce enough energy to power 400,000 households every year.
Employee Seajacks: “In the second phase of installing a wind turbine, each foundation pile is fitted with a ready-made transition piece. Each transition piece weighs 270 tons. A crane lifts the transition piece and slides it over the foundation pile, overlapping it 7 metres. We place the transition piece perfectly vertical, and correct any error in the foundation pile, which may be a maximum of 0.3 degrees out of perpendicular. We do this using special custom-made Holmatro cylinders. In the hollow space formed, we pour almost 10 m³ of grout (concrete), in order to finally anchor the transition piece to the foundation pile. During the hardening process, we keep the elements exactly in the right position, regardless of the weather conditions.”
