KEY COMPONENT SUPPLIERS

Sofia has signed contracts with suppliers for each of the key components of the wind farm. Most of the supply chain opportunities for the wind farm's construction will be through these Tier 1 (and their Tier 2) suppliers:

Turbines

Siemens Gamesa Renewable Energy will supply 100 of its new state-of the-art 14MW machines to the project. It will be the first offshore wind farm in the world to use these turbines.

HVDC transmission system

A consortium of GE's Grid Solutions and Sembcorp Marine has carried out early works and will supply the two HVDC converter stations - one onshore and one offshore - and the offshore converter platform.  

Submarine and land export cables

Prysmian Group will 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 will be responsible 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.
