The Port of Hartlepool is to become the hub for the Teesside Offshore Windfarm Project.
Over the next seven months, EDF Energy will use the port as a hub for all the materials and components needed to build the wind farm.
Over 100 people will be involved in the offshore construction programme and the logistics of the supply chain operation is being handled by PD Ports.
Tim Bland, EDF Energy Renewables' project manager for the Teesside Offshore Windfarm, said that building offshore throws up unique challenges.
"[It] requires much closer integration of design, construction and materials supply activities than an onshore wind farm because of the additional challenges of operating at sea and the vagaries of the weather," he said.
The 27-turbine Teesside windfarm will have a capacity of 62 megawatts, providing enough energy to power up to 40,000 households.
Siemens will be supplying and installing the 2.3MW turbines, while Van Oord will provide the balance of plant, including foundations and sub-sea cabling.
