Experience: 18–20 Years
Plant Type: Combined Cycle Power Plant (~230 MW)
Location: Project Site

The Mechanical Lead shall be responsible for complete execution, supervision, and management of erection, pre-commissioning, testing, and commissioning of all mechanical systems of a Combined Cycle Power Plant.

The role requires deep expertise in Gas Turbine, Steam Turbine, HRSG, Diverter Damper/Bypass Stack systems, rotating equipment, valves, and Balance of Plant (BOP), along with strong site leadership and cross-functional coordination.

The incumbent will also support overall site management in the absence of the Project Head, ensuring smooth execution and adherence to project timelines.

Owendo, being a relocation project site, the posting will be initially at the GVK site for a period of 6 months max, till completion of dismantling and transportation of Plant & later on the candidate has to relocate to the final location Gabon during construction of Plant , Installation, Erection & Commissioning.

However, the other two Projects, Port Gentil & Lambrane, being Simple cycle Plants, with bare minimum BOP equipment & less challenges during Erection & Commissioning phase, we will have the similar JD but with lesser experience , which I shall also share with HR.
