MAINTENANCE MECHANICAL ENGINEER

Job Purpose

Support the safe, reliable, and efficient operation of an Oil & Gas storage terminal by providing technical

engineering expertise, maintenance supervision, troubleshooting, equipment reliability improvement, and

maintenance execution support.

The Maintenance Mechanical Engineer is responsible for ensuring that assigned maintenance activities are

properly engineered, planned, executed, inspected, and documented in accordance with applicable engineering

standards, manufacturer recommendations, approved procedures, and HSSE requirements.

The position plays a key role in improving asset performance, developing maintenance strategies, supervising

technical execution, and strengthening the competence of Maintenance Technicians and Technical Assistants.

Key Responsibilities

Maintenance Engineering & Execution

• Provide technical engineering support for preventive, predictive, corrective, and breakdown maintenance

of mechanical equipment and terminal infrastructure.

• Supervise and coordinate maintenance activities involving centrifugal pumps, mechanical seals, valves,

piping, loading arms, firefighting systems, and other rotating and static mechanical equipment.

• Review maintenance work orders, technical scopes, work instructions, spare parts requirements,

manpower, tools, and execution methodologies.

• Coordinate with Maintenance Planning and Operations to establish maintenance priorities, schedules,

equipment availability, and resource requirements.

• Ensure maintenance activities are executed in accordance with approved engineering specifications,

drawings, manufacturer recommendations, and quality requirements.

• Review maintenance findings, inspection results, equipment testing, and reinstatement requirements

before recommending equipment return to service.

Equipment Reliability & Asset Integrity

• Investigate equipment failures, recurring defects, and abnormal operating conditions, identifying root

causes and recommending corrective and preventive actions.

• Support development and optimization of preventive and condition-based maintenance strategies.
• Review equipment maintenance history, failures, performance trends, and work order data to identify

reliability improvement opportunities.

• Support equipment criticality assessments, Failure Mode and Effects Analysis (FMEA), and ReliabilityCentered Maintenance (RCM) initiatives.
• Coordinate equipment inspections, condition monitoring, and integrity assessments with relevant

specialists.

• Identify and escalate asset integrity concerns, overdue inspections, and safety-critical equipment

deficiencies.

• Support reliability improvement initiatives to reduce equipment failures, maintenance backlog, and

unplanned downtime.

Engineering & Technical Documentation

• Develop, review, and improve mechanical maintenance procedures, work instructions, inspection

checklists, and technical specifications.

• Review mechanical drawings, P&IDs, equipment manuals, and technical documentation required for

maintenance execution.

• Prepare technical scopes of work, material specifications, and engineering justifications for maintenancerelated modifications and repairs.
• Provide engineering support for equipment modifications, replacement, upgrades, and minor

improvement projects.

• Ensure maintenance records, inspection findings, equipment histories, and technical documentation are

accurate and traceable.

• Support Management of Change (MoC) processes, technical risk assessments, and engineering reviews

within delegated authority.

HSSE, Process Safety & Quality

• Ensure assigned maintenance activities comply with terminal HSSE requirements, Permit to Work (PTW),

isolation procedures, Life Saving Rules, and applicable engineering standards.

• Participate in Job Safety Analyses (JSA), risk assessments, incident investigations, and technical safety

reviews.

• Verify that maintenance activities have appropriate technical controls, work instructions, inspection

requirements, and acceptance criteria.

• Identify unsafe conditions, technical deviations, quality deficiencies, and potential equipment integrity

risks.

• Exercise stop-work authority when activities are unsafe or required controls are not established.
• Support inspection, testing, and quality verification of contractor maintenance activities.
• Ensure corrective and preventive actions arising from maintenance failures, audits, inspections, and

incidents are properly followed up.

Team Coordination & Competence Development

• Provide technical guidance and supervision to Maintenance Technicians, Junior Maintenance

Technicians, and contractors.

• Support structured training, practical competency assessments, and development of junior maintenance

personnel.

• Coordinate technical activities with Operations, Maintenance Planning, Procurement, Warehouse, HSSE,

and Projects.

• Review work execution performance, identify technical capability gaps, and recommend training or

improvement actions.

• Promote safe working practices, technical discipline, accountability, and continuous improvement within

the Maintenance team.

Maintenance Performance & Resource Management

• Monitor maintenance performance indicators, including preventive maintenance compliance, corrective

maintenance backlog, equipment reliability, and work order quality.

• Support maintenance budget preparation, cost estimates, material requirements, and resource

optimization.

• Review spare parts requirements, technical specifications, material suitability, and stock criticality.
• Evaluate contractor technical performance, work quality, productivity, and compliance with approved

scopes.

• Prepare maintenance engineering reports, technical recommendations, failure analyses, and

improvement proposals for management review.

• Support shutdown planning, major equipment overhauls, commissioning, and maintenance readiness

activities.

Qualifications and Experience

• Bachelor's degree in Mechanical Engineering or a related engineering discipline.
• Minimum 10 years of relevant experience in mechanical maintenance engineering within Oil & Gas,

petrochemical, refinery, bulk liquid storage terminals, or similar process industries.

• Practical experience with centrifugal pumps, mechanical seals, valves, piping systems, rotating

equipment, and mechanical maintenance activities.

• Good understanding of preventive, predictive, corrective, and condition-based maintenance strategies.
• Experience in equipment failure investigation, troubleshooting, root cause analysis (RCA), and reliability

improvement.

• Knowledge of relevant engineering standards and industry practices, including applicable API, ASME,

and ISO standards.

• Familiarity with Process Safety Management, PTW, isolation procedures, Management of Change, and

industrial HSSE requirements.

• Ability to interpret P&IDs, mechanical drawings, technical specifications, and equipment documentation.
• Experience with maintenance management systems such as HxGN, SAP, INFOR EAM, or equivalent.
• Experience in technical contractor coordination, maintenance planning, and equipment inspection is

advantageous.

• Good written and verbal communication skills in English.

Required Skills and Competencies
