During 2020 Sofia will select its preferred Tier 1 suppliers for each of the key components of the wind farm. In 2021, when the project achieves final investment decision, the contracts will be confirmed. Most of the supply chain opportunities for the wind farm's construction will be through the Tier 1 suppliers. To date Sofia has selected the following:
Siemens Gamesa Renewable Energy is set to supply 100 of its new state-of the-art 14MW machines to the project.
HVDC transmission system
A consortium of GE's Grid Solutions and Sembcorp Marine have been chosen to carry out early works and are lined up to supply the two HVDC converter stations - one onshore and one offshore - and the offshore converter platform.
Submarine and land export cables
Prysmian Group is set to provide a turn-key high voltage submarine and land export cable connection, including use of brand-new cable installation vessel Leonardo da Vinci and innovative cable technology.
Foundations and array cables
Van Oord has been named as the preferred supplier for the engineering, procurement, construction and installation of both the monopile foundations and array cables for the project. Through its UK branch MPI Offshore, Van Oord will create a logistics hub on the North East to deliver the comprehensive scope of work.
