DNO, a Norway-based oil and gas operator focused on the Middle East and the North Sea, has announced the removal of wellhead platform production facilities from the Schooner field, offshore UK.
Schooner is the last major offshore operation under the company’s multi-year North Sea decommissioning programme.
The decommissioning was carried out by the Netherlands-based Heerema Marine Contractors, using the Thialf semi-submersible crane vessel.
DNO said that the platform deck, which weighs 1,200 tonnes, has already been lifted aboard the vessel, and the jacket was removed after the piles had been cut three meters below the seabed.
The deck and jacket have been transported to the Hoondert Yard in the Netherlands, for dismantlement and recycling, said the oil and gas operator.
DNO 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.”
