Perenco UK (PUK) has started decommissioning work in the Southern North Sea (SNS).

The work is being performed by Petrodec’s Obana heavy lift jack-up vessel, the largest self-elevating vessel of its type, the company said. Obana is initially being deployed on Block 48/12a to remove the Galahad platform topside and jacket, Perenco said in a release Sept. 8.

After Galahad, Obana will move to Amethyst field for the removal of the C1D, A2D, and B1D jackets, expected to be completed and offloaded in The Netherlands later this year.

Obana was built to perform complex and heavy decommissioning offshore work in water depths up to 65 m. It is equipped with a 2,000-tonne crane and has 3,800 sq m and up to 12,000 tonnes of deck capacity equipped with roller systems capable of rearranging components on deck to remove multiple modules in a single campaign.
