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 meters below the seabed.

"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," said DNO's Chief Operating OfficerChris Spencer .
