Abstract
C-Power’s wind farm is located on the Thornton Bank, approximately 30 km off the coast of Zeebrugge. The project was constructed in three phases.
Phase 1 (2007-2009), the pilot phase, consisted of six 5M (5 MW) wind turbine generators (WTG) on gravity base foundations (GBF). The 30 MW installed capacity is fully operational since end of June 2009.
Phase 2 (2011-2012) consisted of:
- the construction of 49 jacket foundations (JF);
- the installation of 30 WTGs of 6,15MW: 24 WTGs in sub area B and 6 WTGs in sub area A, mutually connected with 33/36 kV infield cables;
- the laying and connection of infield cables;
- the crossing of the 33/36kV infield cables with the Interconnector gas pipeline and the Concerto South telecom cable;
- the construction and installation of the offshore transformer station (OTS);
- disconnection works of 150/170kV cable A from D1 and connection to transformer station and the connection of a 33kV infield cable between OTS and D1;
- the installation of 2 subsoil 150kV onshore connections between the 150 kV offshore cables and the high voltage station “Sas Slijkens”;
- the laying of the second 150kV offshore export cable B.
Phase 3 (2012-2013) consisted of:
- the installation of 18 WTGs (6,15MW) and the necessary connections with the offshore transformer station
The complete project comprises 54 WTGs with a total rated power of 325 MW plus the supporting infrastructure. Full operation was accomplished by end of September 2013.
In 2022, C-Power continued the “in house” organisation of its turbine maintenance activities, meaning without reliance on an “all in” service contract, to the satisfaction of its shareholders and financing institutions. The C-Power subsidiary Thornton Bank Maintenance Services and the Belgian maintenance company John Cockerill (formerly CMI) continued to perform the major maintenance works on the wind farm (refer to the Annual reports of previous years). For specific maintenance activities, requiring specialized knowledge, long-term agreements were concluded with a range of contractors, both from Belgium as abroad. C-Power took over the full responsibility for logistics, warehousing, and sourcing of spare parts.
These changes had no impact on the safety and environmental policy and management of C-Power.
