ABERDEEN  Plexus Holdings Plc, an oil and gas engineering services provider, has completed its work for the plug and abandonment P&A equipment and services campaign for Oceaneering International Services Ltd. 

The P&A order from Oceaneering included tieback and subsea well control equipment together with hydraulic controls and services in a configuration designed for vessel-based deployment and work. Plexus provided its multi-release connector, together with an annular BOP and hydraulic control system in a package called the Mud Containment System.

The equipment was deployed from a vessel in the North Sea and guided by a ROV to attach to well conductors to facilitate P&A work on the well and closed-loop circulation of well fluids. The system was used on four different wells over a two-month offshore deployment.

This order generated revenues of £850,000 ($1 million) for Plexus in the 2023 financial year, which is a 70% increase on the initial estimates.
