LEIDSCHENDAM, the Netherlands — Heerema Marine Contractors is using Fugro’s camera system to support installation of 27 wind turbines for Parkwind’s Arcadis Ost 1 wind farm offshore northern Germany.
It is located in the Baltic Sea off the German coast.
The Rotor-Nacelle Assembly (RNA) installation method deployed for this project involves placing the turbines, with the blades pre-assembled on deck, onto the tower fixed on the foundation.
QuickVision assists remote positioning of the assembly within the necessary tolerances.
Sándor Hötte, senior installation engineer at Heerema, said the camera technology “gives us that extra certainty required to install the RNA on the tower whilst removing the need to have engineers visually observing under the load.”
According to Heerema, the main challenge when using a floating installation vessel is managing the relative motion between the suspended load in the vessel’s heavy-lift crane and the top of the foundation tower.
QuickVision provides real-time information to assist monitoring of the lifting, positioning and lowering phases of the installation, allowing the RNA to be set down with an accuracy of less than 2 cm, Fugro said.
Arcadis Ost 1 is a 257-MW development in the Baltic Sea. Installation started last October and commissioning should finish later this year.
