offshore wellThe Norwegian oil and gas operator, DNO ASA, has reported that the wellhead platform production facilities have been removed from the Schooner field offshore the UK, signifying the last major offshore operation under DNO’s multi-year North Sea decommissioning campaign.

DNO’s Chief Operating Officer, Chris Spencer, said, “We have conducted these operations in a safe, cost-efficient and environmentally responsible manner, coordinating five tier-one contractors and displaying our capabilities as a full life-cycle offshore operator.”

The heavy lift was conducted using the Heerema Marine Contractors’ Thialf semi-submersible crane vessel. The 1,200 tonne platform deck was lifted aboard the vessel on 17 May, while the jacket was removed on 23 May after the piles had been cut three metres below the seabed. The deck and jacket have been transported to the Hoondert Yard in the Netherlands for dismantlement and recycling.
