The first two of five SPAR-type floating foundations built by Spain's Navantia-Windar consortium for Statoil's 30 MW Hywind Scotland floating wind farm has been loaded onto OHT's semi-submersible vessel Albatross.

The pair were loaded at Fene shipyard, northern Spain, which was the first load-out operation of its type carried out at the shipyard, according to the Spanish consortium.

Each structure is 91 m in length, has a diameter of 14.8 m and weighs 3,450 tonnes.

The remaining three foundations will be shipped out at the end of May and at the beginning of June. 

Statoil has already started assembling the five Siemens 6 MW turbines and towers in Stord, Norway, where they will be mounted onto the floating foundations, towed to the installation site some 25 km off the coast of Peterhead, Scotland and anchored in water depths exceeding 100 m.

The wind farm, owned by Statoil (75 percent) and Masdar (25 percent), is expected to be commissioned in late 2017.
