CAPE Holland

CAPE Holland carried out foundation installation work at Eneco’s Princess Amalia offshore wind farm (Prinses Amaliawindpark) in the Netherlands, where it participated in installing a Delft Offshore Turbine (DOT) monopile. The activity was reported as an on-site installation operation at the existing wind farm location, demonstrating monopile installation using a vibro-based method. The installation used Heerema’s Vibro Lifting Tool deployed from the vessel Aegir, with the monopile vibrated into the soil. The method combined vibro-hammer functionality with lifting capability, reducing the need for additional handling tools typically required to pick up, upend, and drive the pile to final penetration. The installation was performed with the vessel operating in floating mode on dynamic positioning (DP), with the monopile free-hanging from the crane hook and without a motion compensation frame. The report stated that verticality was monitored during pile driving so that the vessel and crane could control alignment while operating in DP mode. The result achieved installation within a 0.5 m target box and an inclination of 0.3 degrees, demonstrating the performance of the vibro-installation approach for monopile placement at the Prinses Amaliawindpark site.
