Trident Energy have been operating the Pampo and Enchova mature fields in offshore Brazil since July 2020. Since the acquisition, the company has been working hard to revitalise the fields to extend their operational life. Most recently, they launched their first saturation diving campaign in Brazil and the second in Trident´s history.

The campaign was successfully completed by the team and partners. 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 (RTP).

To execute the work, they hired a Diving Support Vessel (DSV), DOF Skandi Achiever, and a Brazilian diving company, SISTAC, that provided the saturation divers. It had been five years since saturation diving was carried out in Brazil, and the HSE department was heavily involved during the planning and offshore execution ensuring the safety of the divers.

Below is a list of some great achievements:

• 20 days campaign completed on time and on budget
• 28 successful saturation dives
• 150 hours of diving time
• 0 LTIs
• 4,000+ barrels of oil per day (bopd) potential production return
• 0 downtime

Considering the complexity of the mobilisation of resources for the saturation diving campaign and to get the most out of the project, the company 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.

Trident Energy is very proud of the excellent results achieved and want to say a huge well done to their teams in Brazil and London who put a lot of effort and collaboration into planning and executing this campaign.
