Fugro has completed offshore works undertaken in preparation for full construction of the European ƶijϻ Wind Deployment Centre (EOWDC) at Aberdeen Bay, Scotland.
The geotechnical site investigation took place at 11 turbine locations to assess the seabed, with the data acquired being used to inform the final design and micro-siting of the turbine foundations. Full offshore construction is scheduled to start in late 2017 or early 2018, after an investment decision later this year.
Fugro’s dynamically-positioned 78m geotechnical drilling vessel, the Bucentaur, was mobilized to the EOWDC site, located about 2-5km off the coast of Aberdeen. The site investigation work was on behalf of Aberdeen ƶijϻ Wind Farm Ltd (AOWFL).
“A two phased approach was adopted over a period of 11 days,” said Dennis van den Bulk, Fugro’s senior project manager. “During the first phase we conducted seabed CPTs and seismic CPTs down to refusal at each of the turbine locations, and in the second phase we drilled three boreholes. The offshore phase was completed safely, successfully and without any significant downtime, validating the solution.”
The data and samples acquired during the field phase were transferred to Fugro’s Wallingford laboratory and offices for further analysis and reporting.
Vattenfall and Aberdeen Renewable Energy Group (AREG) are the partners behind AOWFL.
“EOWDC will help establish the northeast of Scotland as a global center of innovation for the offshore wind industry,” said Andy Paine, head of UK offshore wind development for Vattenfall and project director for AOWFL. “It is through test and demonstration of next generation products and services that offshore wind will become a low cost sector.”
