Key Responsibilities Areas (KRAs) and Initiatives

Mechanical Equipment Design and Specification

• Develop, detailed specifications and datasheets for complex mechanical equipment (e.g., pumps, compressors, pressure vessels, heat exchangers) using industry codes (e.g., ASME, API) to ensure accurate procurement, reliable performance, and safe operation of assets.
• Perform detailed engineering calculations—including stress analysis, vibration analysis, and material selection studies—to ensure mechanical equipment and piping systems can safely withstand operational loads and environmental conditions, helping to prevent failures, equipment damage, and unplanned downtime.
• Support the technical evaluation of vendor proposals by reviewing equipment specifications, checking compliance with project requirements, handling technical clarification queries, and helping confirm that selected machinery is fit‑for‑purpose, reliable, and meets all safety and design standards.
• Assist in developing and updating standard engineering specifications and design philosophies by applying industry best practices (such as API standards) and incorporating lessons learned, helping ensure consistent, high‑quality design work that supports asset integrity and reduces operational risk
• Review mechanical engineering deliverables—including technical reports, calculation sheets, and vendor drawings—by performing detailed quality checks to verify design accuracy, compliance with engineering standards, and alignment with other disciplines, helping to minimize rework during construction.

Asset Integrity, Reliability, and Operational Support

• Support asset integrity programs by performing condition assessments (such as API 579 Fitness‑for‑Service evaluations), reviewing maintenance strategies, and assisting in the coordination of repair scopes to help ensure the long‑term safety, reliability, and performance of mechanical equipment.
• Provide expert technical support for production equipment and processes by troubleshooting complex mechanical issues, conducting detailed root cause analysis (RCAs) for failures, and recommending timely solutions to minimize unplanned downtime, restore production quickly, and ensure sustained facility availability.
• Support the engineering activities during Turnarounds (TAR) and major maintenance events by helping define mechanical work scopes, coordinating repair and replacement plans, and participating in quality control (QC) inspections to ensure equipment is safely restored and returned to service efficiently.
• Assist in the selection of materials and corrosion control strategies by applying knowledge of metallurgy, corrosion mechanisms, and protective coatings to ensure compatibility with process fluids, minimize equipment degradation, and help maintain the mechanical integrity and lifespan of facility infrastructure.
• Support condition monitoring programs by helping define monitoring requirements and interpreting equipment performance trends to identify early signs of degradation, enabling timely preventive maintenance and improving overall asset availability.

Piping Design and Engineering Excellence

• Develop and verify detailed piping designs—including layouts, routing, isometrics, and material specifications—using CAD/3D modelling tools and applying relevant international standards (such as ASME B31.3) to ensure efficient space utilization, safe access for operations and maintenance, and reliable system performance.
• Perform piping stress analysis using specialized software (such as CAESAR II) to evaluate the effects of operational loads, temperature variations, and environmental factors (e.g., wind or seismic activity), ensuring piping systems operate safely without excessive stress on connected equipment and helping prevent failures, equipment damage, and unplanned downtime.
• Support the specification and material selection for piping components—including valves, fittings, gaskets, and insulation—by working closely with process engineers to ensure compatibility with process fluids, corrosion resistance, and compliance with company standards, helping to maintain asset integrity and extend equipment lifespan.
• Develop and maintain accurate piping deliverables—including P&IDs, isometric drawings, and Bills of Materials (BOMs)—by performing thorough quality checks and coordinating with relevant disciplines to ensure fabrication accuracy and reliable construction, helping to minimize rework and prevent project delays.
• Support project scoping during Front-End Engineering Design (FEED) by providing accurate estimates for bulk materials—such as piping, fittings, and structural steel—to help ensure reliable cost forecasts and proper planning for downstream design and construction activities.

Plant Layout and Spatial Integration

• Support the development and coordination of plot plans and 3D facility models by integrating inputs from process, civil, and E&I disciplines to ensure efficient equipment layout, safe maintenance access, and proper routing and integration of piping systems.
• Participate in interdisciplinary review meetings (such as 3D model reviews) by assisting with clash detection and helping resolve spatial integration issues to ensure a coordinated design that prevents interference between piping, structural, electrical, and other components during construction.
• Contribute to equipment layout and pipe rack design by applying sound engineering judgment on operability, maintainability, and safety considerations, helping ensure efficient workflows, safe personnel access, and effective use of space within the facility footprint.
• Incorporate ergonomic considerations into facility layouts by designing and reviewing access platforms, ladders, walkways, and operating areas to support safe working conditions, improve operator accessibility, and enhance the efficiency of maintenance and routine operations.
• Assist in integrating utility and non‑process piping systems—such as firewater, sewage, and drainage—into the overall facility layout by coordinating with discipline specialists to ensure comprehensive, compliant designs that meet operational support and safety requirements.

Process Safety Management (PSM) and Compliance

• Support the mechanical engineering review within the Management of Change (MOC) process by evaluating scope changes, identifying potential mechanical risks, and checking proposed mitigation actions to help ensure that all modifications are technically sound, safe, and aligned with integrity requirements before implementation.
• Support mechanical design and operations compliance by conducting formal checks and reviews against applicable safety regulations and international codes (such as ASME and API), helping to verify that equipment designs meet required standards, reduce integrity risks, and maintain alignment with regulatory expectations.
• Participate in formal hazard analysis reviews—such as HAZOP (Hazard and Operability Study) and PSSR (Pre‑Startup Safety Review)—by providing mechanical insights on equipment limitations, potential failure modes, and existing safeguards to help ensure that mechanical risks are fully identified, evaluated, and addressed in the design
• Support the engineering and validation of pressure equipment integrity by assisting with inspection planning, reviewing inspection and integrity assessment reports, and checking compliance with applicable pressure vessel regulations to help prevent failures and ensure the safety of personnel and the protection of the environment.
• Support incident investigation teams by providing detailed mechanical analysis and engineering insights to determine root causes of equipment failures and recommend effective corrective actions that drive continuous safety improvement and prevent recurrence of incidents.
