• Execute commissioning of Air compressors, dryers, and pneumatic systems.

• Validate performance of Fuel oil, lube oil, cooling water, and freshwater systems.

• Lead testing and commissioning of Cranes, winches, and deck machinery.

• Verify mechanical integrity of emergency and safety systems 3. Interface Management & Coordination

• Act as the key interface between construction, engineering, electrical, instrumentation, marine, and drilling disciplines.

• Coordinate activities with OEM vendor representatives during installation, testing, and troubleshooting.

• Participate in commissioning meetings, progress reporting, and HSE briefings.

• Support integration testing between marine, drilling, and jacking systems.

4. Safety, Regulatory & Class Compliance

• Implement offshore safety standards (PTW, JSA, SIMOPS, LOTO).

• Ensure all commissioning activities follow class rules (ABS, DNV) and international standards (API, IMO, SOLAS).

• Lead punch list creation, categorization, and closure for mechanical systems.

• Participate in HAZOP, HAZID, and system readiness reviews. Ensure documentation aligns with project turnover requirements and offshore audit expectations.

5. Troubleshooting & Technical Support

• Resolve mechanical, hydraulic, and rotating equipment issues during commissioning.

• Identify design or installation deviations and propose corrective actions.

• Support performance testing and initial rig startup offshore or at shipyard.

• Provide technical guidance to junior engineers and commissioning technicians.

6. Handover & Completion

• Ensure all MC and commissioning documentation is complete and accurate.

• Prepare turnover dossiers for mechanical systems (ITRs, test reports, redlines).  

• Support final acceptance tests and assist the rig crew during start-up and first well operations.  

• Deliver a fully commissioned jack-up rig ready for offshore deployment.
