CORE IMPACT:
Served as the commercial and technical lead overseeing the transition of two major power assets from EPC construction to stable operation. Protected project margins during the Defects Liability Period (DLP) by enforcing strict adherence to contract scope.

PROJECT PORTFOLIO:
► Renaissance Project CCPP (190MW): Old Harbour Bay. Combined Cycle Configuration (3x1). Tech Stack: Gas Turbines GE 6B.03 + 3 Vogt HRSGs + Steam Turbine GE Alstom.
► JAMALCO CHP (100MW): Clarendon Combined Heat & Power. Tech Stack: 2 Vogt HRSGs + Balance of Plant (BOP).

KEY ACHIEVEMENTS:
• Claims Resolution: Successfully adjudicated and closed 700+ warranty claims with a 95% resolution rate, preventing potential liquidated damages.
• Asset Handover: Managed the high-friction turnover of the 3x1 Combined Cycle configuration and a Cogeneration Plant, ensuring all punch-list items were cleared.
• Negotiation: Led technical-commercial disputes with Plant Owners, OEMs, Insurance Companies, and local contractors, preventing "scope creep" and ensuring compliance with technical specifications and the EPC contract.

Competencies: Contract Management | Warranty Defense | GE 6B.03 / Alstom | Vogt HRSG | Stakeholder Negotiation.

CORE IMPACT:
Recruited to establish the Maintenance Department from zero for the Shagaya 50MW Concentrated Solar Power (CSP) plant. Built the entire operational infrastructure—team, budget, CMMS, and key operational support services (local contractors)—for a Parabolic Trough facility with Molten Salt Thermal Storage.

PROJECT PORTFOLIO:
► Shagaya Renewable Energy Park (50MW CSP): Parabolic Trough Technology with 9-hour Molten Salt Energy Storage.
► Tech Stack: Siemens Steam Turbine (SST-700RH) + HTF System + Solar Field + Balance of Plant (BOP).

KEY ACHIEVEMENTS:
• 30% Cost Reduction: Executed a rigorous Criticality Analysis on the initial spare parts inventory (MRO), reducing the investment budget by 30% without compromising plant reliability.
• Digital Transformation: Led the full implementation of Avantis Pro (CMMS) from database population to workflow automation, ensuring 100% Preventive Maintenance (PM) coverage at startup.
• EPC to O&M Handover: Achieved successful plant reception within contractual dates, transitioning a team of 25+ multidisciplinary technicians from construction support to full commercial operation.

Competencies: Budget Optimization | Greenfield Plant Setup | CMMS Implementation (Avantis) | Renewable Energy (CSP) | Multicultural Leadership.

Deployed on a strategic mission to optimize maintenance scheduling for the Rabigh IWSPP (Independent Water, Steam and Power Producer). Focused on debottlenecking critical path activities during outages and restructuring the planning logic for a massive multi-utility complex.

PROJECT PORTFOLIO:
► Rabigh IWSPP (600MW Power + 4, 230 t/h Steam + 8, 000 t/h Water): Supplies the Petro Rabigh Petrochemical Complex.
► Tech Stack: 9x Boilers + 5x Steam Turbines + 3x Mitsubishi (MHI) Flue Gas Desulfurization (FGD) Units + 16-Train Reverse Osmosis (RO) Desalination Plant.

KEY ACHIEVEMENTS:
• 16% Downtime Reduction: Redesigned the shutdown logic for the Combustion Gas Desulfurizers (FGD), reducing maintenance downtime from 400 hours to 336 hours (16% improvement).
• Planning Precision: Achieved a 98% completion rate for issued Work Orders by restructuring the "Look-Ahead" planning process and clearing backlog.
• Asset Reliability: Established and maintained 90% Preventive Maintenance (PM) coverage for all equipment, strictly adhering to OEM requirements to prevent premature failures.

Competencies: Shutdown Planning | Reverse Osmosis Desalination | Steam Generation | MHI FGD Systems | CMMS (OCEN).
