Royal Boskalis Westminster N.V. (Boskalis) has been awarded the Offshore Balance of Plant contract by Vattenfall for the construction of Aberdeen Offshore Wind Farm, also known as the European Offshore Wind Deployment Centre. Following the announcement on 29 June stating that Boskalis was the preferred contractor, the contract has now been formally awarded. The project will consist of eleven wind turbines with a capacity of 92.4 MW. The contract includes all offshore elements of the wind farm, with the exception of the wind turbine supply. The contract carries a value for Boskalis of well in excess of EUR 100 million.
Aberdeen Offshore Windfarm is located approximately 3 kilometers off the coast of Aberdeen, United Kingdom. The scope of the activities for Boskalis includes the design, procurement, fabrication, supply, transportation and installation of eleven suction bucket jacket foundations and scour protection, the procurement, supply, transportation and installation of 66kV inter-array and export cables by Boskalis subsidiary VBMS and the provision of the wind turbine transportation and installation vessel.
The use of suction bucket jacket foundations in conjunction with the large wind turbines and the use of high capacity 66kV power cables makes this project unique.
The offshore project execution is scheduled to commence in September 2017. The foundations and cables will be transported and installed with own assets including a fallpipe vessel, transport barges, a large floating sheerleg crane and a cable laying vessel. The installation of the wind turbines will be carried out with an installation vessel supplied by Boskalis. Completion of the project is expected in the second quarter of 2018.
