LONDON — Trident Energy has been operating the Pampo and Enchova mature fields offshore Brazil since July 2020. Since the acquisition, the company has been working to revitalize the fields to extend their operational life.
Trident recently launched its first saturation diving campaign in Brazil (the second in Trident´s history), and the campaign was successfully completed. The main objective was to remove two valves, allowing additional integrity tasks to be carried out, and bringing a greater overall result in terms of subsea integrity and potential return to production, the company said.
To execute the work, Trident hired the DOF Skandi Achiever diving support vessel and Brazilian diving company SISTAC to provide the saturation divers.
It had been five years since saturation diving was carried out in Brazil, and Trident said its HSE department was heavily involved during the planning and offshore execution ensuring the safety of the divers.
The company was able to achieve a 20-day campaign completed on time and on budget; 28 successful saturation dives; 150 hours of diving time; 0 LTIs; 4,000-plus bbl/d of oil potential production return; and zero downtime.
Considering the complexity of the mobilization of resources for the saturation diving campaign and to get the most out of the project, we took the opportunity to also carry out other repair tasks on the gas line, control lines, christmas tree and manifold valves, as part of the DOF Skandi Achiever contract.
