When Woodside Energy needed to safely plug and abandon 15 subsea wells in the Enfield field on Western Australia’s Northwest Shelf, soft seabed conditions ruled out conventional clump-weight foundations. ICON Engineering’s proprietary Wellhead Load Relief (WLR) system restricted BOP stack motion to extend wellhead fatigue life, while custom-designed suction cans and shared tethering arrangements reduced foundation numbers and campaign costs. Delivered with zero incidents across a complex, evolving abandonment sequence.
