BOW Terminal has released pictures of the two 850 ton monopiles being lifted onto the dockside.
The monopiles will be used at the project, 85 kilometres off the Netherland's coast, to support the 150 Siemens 4MW turbines.
The delivered foundations were manufactured by the Dutch engineering firm Sif Group, who will build 75 of the project's monopiles. The remaining structures will be built by German contractor EEW.
Gemini is being developed by a consortium of company's, led by Canadian utility Northland Power. Dutch firm Van Oord was handed the EPC contract in May.
