Dietsmann Congo Supports CEC Turbine Overhaul Ahead of March Commissioning

Dietsmann Congo Supports CEC Turbine Overhaul Ahead of March Commissioning
Dietsmann Congo has been instrumental in the ongoing maintenance of the 484 MW gas-fired Centrale Électrique du Congo (CEC) power plant, where one of the three turbines is undergoing maintenance and is set to be recommissioned this month.  Energy Capital & Power (ECP) recently interviewed Jean-Baptiste Baray, Managing Director of Dietsmann Congo, to discuss the company’s role in this project and its contributions to the country’s energy sector.

Can you detail the main industrial maintenance projects you are currently managing in Pointe-Noire? How do you ensure their success?

Industrial maintenance remains our core business, representing 70% of our activities in Congo. Our main contract is the general maintenance of all TotalEnergies EP Congo facilities, covering three offshore sites: PNGF-Nord, Moho-Bilondo with the FPU Alima and Moho-Nord with the FPU Likouf and the TLP. Additionally, we manage the Djeno oil terminal and TotalEnergies' operational base, with about 350 employees – 90% nationals and 10% expatriates. We recently began a general maintenance contract with Trident Energy, managing Nkossa’s overall maintenance with approximately 100 employees. We also handle maintenance for EXPRO on the OPT site, which processes gas for LNG production as part of the NILNG Congo projects. Additionally, we conduct wellhead maintenance in collaboration with original equipment manufacturer.

Do you have other operations beyond maintenance?

While maintenance is our primary activity, we also provide technical assistance and staff for various clients. Another expanding sector for us is construction work in electricity, subcontracting and automation. We executed the implementation phase for the construction of the OPT site and regularly work with oil companies like TotalEnergies and Congo’s national oil firms. We have also participated in tenders related to the port extension project and are looking to expand beyond oil and gas.

Regarding the development of gas infrastructure, how does Dietsmann Congo adapt its strategy in Congo to seize the opportunities presented by LNG projects and gas-to-power initiatives?

Dietsmann has operated in the oil and gas sector since 1977, and while production methods differ, maintenance fundamentals remain the same. Whether for oil or gas, we continue offering our expertise, as equipment and maintenance processes are largely similar. Our strength lies in our long-standing presence in Congo, extensive site knowledge and a highly trained workforce.

What training programs do you have in place to enhance local expertise in maintenance and related services?

We have developed workforce training plans since the early 2000s, particularly under contracts with TotalEnergiesand CEC. Our flagship training initiative, the Technical Assessment Campaign Training (TACT), maps staff skills, assesses technical competencies and defines necessary training. Each TACT cycle lasts about three years, and we are currently on our fourth iteration. These programs have significantly increased national staff participation, with national trainers now replacing expatriates. Additionally, we offer both in-person and online training.

How do you ensure operational efficiency at the power plant?

Since 2011, we have managed both operations and maintenance at the power plant. Our efficiency stems from a stable workforce, direct collaboration with technical experts and a streamlined supply chain. Unlike larger corporations, our procurement process is flexible, ensuring a continuous supply of spare parts. We maintain turbine availability at approximately 99%, though power cuts primarily stem from distribution issues rather than production inefficiencies.
