The world’s largest jack-up rig has commenced operations in the Southern North Sea, marking a significant step in Perenco UK’s offshore decommissioning program. The rig, Obana, operated by Petrodec, has started dismantling the Galahad platform, including both topside and jacket structures.

Following this campaign, the rig is scheduled to continue work across additional Perenco UK assets, including jacket removals at the Amethyst field later this year. The company said the project highlights its commitment to carrying out safe and efficient decommissioning of mature offshore infrastructure in UK waters.

Perenco UK noted that the arrival of the Obana represents one of the largest single asset removal efforts in the Southern North Sea, contributing to the broader transition of the basin as older fields are retired.
