OIS Wins Multiple Well Abandonment Contract In North Sea

May 12:

Offshore Installation Services (OIS), an Acteon company, said it has been awarded a contract to decommission multiple wells in the North Sea by Centrica Energy.
The initial campaign includes six subsea wells in the central North Sea, in categories 2.1 and 2.2, which will be abandoned using a diverless, vessel-based approach.
Planning and engineering are underway, and the offshore scope of the Centrica contract will mobilize in summer 2015. Because of the high degree of flexibility permitted with the rigless operations, OIS continues to engage with other North Sea operators interested in joining the campaign, the company said.
The campaign will be conducted from an anchor-handling tug supply vessel (AHTS), the Island Valiant. During phase one, the Suspended Well Abandonment Tool (SWAT) system from sister Acteon company Claxton Engineering Services will be deployed through the vessel’s moon pool to set cement plugs in the bore and across all the casing annuli.
The second phase will use an abrasive severance system for the cutting of the wells and sequential removal from the seabed. This will conclude the offshore operations.
Since 1996, OIS has successfully completed more than 118 well decommissioning projects without a single lost-time incident, the company said.
OIS, headquartered in the U.K., performs turnkey projects, which include complete offshore and onshore project management, vessel charter, equipment and personnel.
