Oceanteam Power & Umbilical (OPU) carried out subsea cable installation at Rhyl Flats from July 2008, using the 100 m cable-lay barge AMT Explorer. Scope covered 33 kV inter-array cables connecting the 25 turbines and the 3 × 132 kV export cables running ~8 km to the Towyn landfall (no offshore substation — direct MVAC to onshore distribution network). CCL Group provided cable monitoring and testing during the lay (subcontract scope).
