Fugro supports monopile installation with augmented-reality solution

In: Windfarms
Fugro has used its augmented-reality solutions to support Jan De Nul Group’s offshore installation of two monopiles for the first two offshore wind turbine foundations at the Coastal Virginia Offshore Wind project.

Offshore installation company Jan De Nul Group engaged Fugro’s to support the monitoring of the position, verticality and height of the monopiles which was crucial for installation. Fugro’s surveyors supported the installation offshore on Jan De Nul Group’s jack-up installation vessel
Vole au vent and onshore from a nearby temporary real-time kinematics (RTK) base station set up on the shoreline specifically for the project. They deployed several proprietary technologies including monitoring the heading and verticality in near real time, and applying Fugro’s augmented-reality solutions QuickVision and InclinoCam.

Thijs Prins, Fugro’s Director for Positioning and Construction Support, said: “Jan De Nul Group selected Fugro to support the installation phase because our unique technology precisely monitors monopile installation accuracies. Our close collaboration with the Jan De Nul Group survey team was essential for completing the work scope under challenging conditions in the midst of the Covid-19 pandemic. We are delighted that both monopiles were installed speedily, safely and within the strict tolerances.”

CVOW is one of the first offshore wind farms to be approved by the Bureau of Ocean Energy Management (BOEM) and installed in federal waters. It was built by Ørsted, one of the largest offshore wind developers in the world, on behalf of Dominion Energy, an American power and energy company headquartered in Richmond, Virginia. Ørsted served as offshore engineering, procurement and construction lead for the project.

The pilot project was first announced three years ago and received Virginia State Corporation Commission approval in November 2018. It features two
SWT-6.0-154 wind turbines mounted on jacket foundations. Construction kicked off onshore in July 2019 with foundation installation following in May this year. Construction was completed throughout the pandemic.
