Shell Saves $6million on Subsea Tree Repair

Shell Nigeria Exploration and Production Company, SNEPCo, has said it saved about $6 million on every refurbished Subsea Tree in-country, led by Nigerian engineers.
A Subsea Tree is an arrangement of valves and other components installed at the wellhead to control and monitor production/injection flow.

The oil firm embarked on a Tree Refurbishment initiative in 2013 to ensure timely delivery of the equipment at lower cost for the Bonga Phase 2 project, which comprises drilling and hook-up of in-field wells within Bonga.

SNEPCo’s Engineering Manager Subsea and Pipelines, Mr. ‘Debo Oladunjoye, who leads the refurbishment team, stated that the scope of work entails the retrieval of Subsea Trees for disassembly, repair and rebuild following procedures developed by the Original Equipment Manufacturer (OEM) to international standards and codes.

Managing Director of SNEPCo,Mr. Bayo Ojulari,  said beyond cost consideration, his company is also looking to indigenise the know-how so that Nigerian engineers can acquire the necessary skills.

“We are pleased with this success story. The first Subsea Tree under the programme was installed on schedule in May 2015.

This was the first of its kind re-using a Subsea Tree fully stripped down and refurbished locally in Nigeria, with all of its original functionality restored.”
