Petrodec has deployed its jackup unit OBANA for a new decommissioning campaign in the UK Southern North Sea under work for Perenco UK.

The vessel has reached the Pickerill field, where it will carry out jacket removal work on the Pickerill A and Pickerill B platforms. After that scope is completed, OBANA is due to move back to the Amethyst field to remove the Amethyst A1D jacket within the same program.

The campaign is the second major offshore assignment for OBANA since the unit entered service earlier this year. The jackup was developed for heavy-lift and multi-structure removal work, with a 2,000-tonne crane and capacity to manage large modules during a single offshore campaign.

Offshore activities are expected to continue until the end of June. The unit will then return to shore for offloading and dismantling.

OBANA was built using repurposed drilling rigs and a new mid-section. It is designed for decommissioning operations in water depths of up to 65 m, supporting the wider removal of aging offshore infrastructure in the North Sea.
