Heerema Marine Contractors (HMC) is using Fugro’s innovative QuickVision® camera technology to support its wind turbine installation work in Parkwind’s 257 MW Arcadis Ost 1 wind farm. HMC is installing 27 wind turbines in this wind farm, located in the Baltic Sea off the German coast.
Using a novel floating Rotor-Nacelle Assembly (RNA) installation method, Heerema is installing wind turbines with the blades already pre-assembled on deck, onto the tower fixed on the foundation. Fugro’s QuickVision® technology allows Heerema to position the RNA remotely and efficiently within strict tolerances, whilst reducing personnel risks traditionally associated with offshore installation operations.
“The QuickVision® system 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,” says Sándor Hötte, Senior Installation Engineer at Heerema.
The largest technical challenge for Heerema 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 fixed foundation tower. Fugro’s QuickVision® technology provides real-time information from the camera system ensuring precise monitoring of the lifting, positioning, and lowering phases of the installation process, allowing Heerema to position the RNA with an accuracy of less than 2 cm.
“With this project for Heerema, we have taken the next step in offshore wind installation support, adding RNA installations to our survey capabilities and expanding the applications for QuickVision®,” says Sjoerd Butter, Product Owner Vision Technologies at Fugro.
