All cables (Infield and Export) was manufacturered and installed by ABB on time and budget. Export cable installation was subcontracted to Selöy Undervannsservices (not Baltic Offshore). The export cable installation (offshore part) started in November 2006, the worst possible season. Extreme WOW was encountered but the delivery milestone was still met.
