Industrial Equipment Maintenance Services

Rotating Equipment Service

Pumps, compressors, turbines, and motors are maintained to OEM specifications. Inspections, laser alignment, vibration analysis, and component replacement ensure reliable operation between turnarounds. Bearing condition monitoring and lubrication management extend equipment life.

Piping & Valve Maintenance

Process piping and valve systems require regular servicing to maintain safe operations. Leak detection, fitting repairs, and valve replacement prevent fugitive emissions and maintain system integrity. Pressure relief valve testing and recalibration are performed to code requirements.

Heat Exchanger Servicing

Heat exchangers and coolers are cleaned, inspected, and pressure-tested. Tube bundle inspection, plugging, and retubing services are available. Fouling removal restores thermal performance and reduces energy consumption.

Instrumentation & Control Support

Sensors, transmitters, analyzers, and control systems are inspected, calibrated, and maintained. Loop checks and function testing verify system reliability for safe plant operations.

Electrical & Power Systems

Motors, switchgear, MCCs, and distribution systems are inspected and tested. Thermal imaging identifies hot spots before failure. Insulation resistance testing and circuit breaker maintenance ensure electrical reliability.

Comprehensive Preventive & Predictive Maintenance

The best repair is the one never needed. Potential issues are identified before they cause costly failures through structured maintenance programs.

Preventive Maintenance (PM)

Scheduled inspections and servicing follow equipment manufacturer recommendations and operating hours. Tasks include rotating equipment, lubrication and alignment checks, filter changes and fluid analysis, valve stroke testing and packing adjustment, heat exchanger cleaning and pressure testing, electrical thermography and megger testing, and corrosion monitoring with ultrasonic thickness testing.

Predictive Maintenance (PdM)

Advanced techniques identify developing issues before they become critical:
● Vibration Analysis: Bearing defects, misalignment, and imbalance detected in rotating equipment.
● Oil Analysis: Wear metals, contamination, and fluid degradation monitored.
● Thermography: Electrical hot spots, insulation failures, and refractory issues identified.
● Ultrasonic Testing: Wall thickness measurements track corrosion rates.

Mechanical Integrity Programs

Risk-based inspection (RBI) and fitness-for-service assessments support long-term asset integrity. Inspection frequencies are optimized based on damage mechanisms and operating conditions per API RP 580/581.

Shutdown & Turnaround Management

Plant shutdowns are complex operations requiring months of planning and flawless execution. Shutdown and turnaround projects for oil and gas facilities across the UAE are managed with around-the-clock work to restore operations within tight windows.

Phase 1: Shutdown Planning (12-24 Months Out)

Planning begins long before the outage window: work scope definition based on inspection findings and operating history, critical path scheduling and resource loading, long-lead material procurement and vendor coordination, contractor manpower forecasting and mobilization planning, permit-to-work system development and safety planning, and pre-shutdown site visits with logistics planning.

Phase 2: Turnaround Execution

During the shutdown, multiple work crews are coordinated for maximum productivity: scaffolding erection and insulation removal, equipment access and component disassembly, inspection execution (NDT, visual, dimensional), repairs, modifications, and equipment replacements, simultaneous operations management, and 24/7 supervision with daily progress tracking.

Phase 3: Restart & Commissioning Support

Support continues after maintenance work finishes: plant restart procedures and system verification, startup witnessing and issue resolution, post-turnaround documentation and as-built updates, and warranty tracking with follow-up inspections.

Phase 4: Demobilization & Reporting

Site cleanup, scaffold removal, and equipment demobilization are completed. Comprehensive turnaround reports document all work performed, inspection findings, and recommendations for future outages.

Standards, Certifications & Compliance

ADNOC & International Standards

Maintenance work follows ADNOC specifications and international standards:
● API RP 580 / 581: Risk-based inspection
● ASME PCC: Post-construction and maintenance codes
● API 510 / 570 / 653: Pressure vessel, piping, and tank inspection codes
● ISO 9001 & ISO 45001: Certified quality and safety management

Safety Management

Structured safety systems are implemented on every project: project-specific HSE plans, permit-to-work systems (PTW), job safety analysis (JSA) before each task, daily toolbox talks and safety briefings, and regular safety audits. All personnel hold valid certifications, including basic safety, confined space entry, working at heights, and H2S awareness.

Quality Documentation

Detailed records are maintained for every maintenance task. Work is verified against the required specifications. Clients receive comprehensive reports documenting completed work, inspection results, and recommendations.

Maintenance Projects Delivered Across the UAE

Refinery Turnaround, Dubai

Complete turnaround support for a major refinery unit. The scope included inspection and repair of 12 heat exchangers, 45 pressure vessels, and 8 km of piping. The shutdown workforce peaked at 85 personnel. All work completed within the 28-day window with zero LTI.

Gas Plant Preventive Maintenance, Abu Dhabi

Annual preventive maintenance contract for a gas processing plant. Scope covered rotating equipment (compressors, pumps), valve maintenance, and instrument calibration. Predictive techniques, including vibration analysis and thermography, identified three potential failures before they occurred.

Compressor Overhaul, ADNOC Facility

Major overhaul of two gas compressors completed during a scheduled outage. Scope included rotor removal, bearing replacement, seal upgrades, and alignment. Compressors returned to service with improved efficiency and vibration levels within specification.

FAQs

What is the difference between preventive and predictive maintenance?

Preventive maintenance is scheduled at fixed intervals (time-based or run-hour-based). Predictive maintenance uses condition monitoring (vibration, thermography, oil analysis) to perform maintenance only when needed based on actual equipment condition.

What is a plant turnaround, and how long does it take?

A turnaround is a scheduled shutdown of a plant or unit to perform major inspection, repair, and maintenance activities that cannot be done during operation. Turnarounds are planned 12-24 months in advance and typically executed within 2-8 weeks, depending on scope.

What NDT capabilities are available for maintenance work?

Ultrasonic testing (UT), radiographic testing (RT), magnetic particle (MT), dye penetrant (PT), and visual inspection are available. Certified NDT Level II and III technicians perform examinations.

What certifications do maintenance technicians hold?

All personnel hold valid certifications, including basic safety (OSHAD/ADNOC), confined space entry, working at heights, H2S awareness, and job-specific qualifications (welding, NDT, rigging, and equipment-specific OEM training).

What is the cost range for plant maintenance contracts?

Costs vary based on facility size, equipment complexity, and maintenance scope. Typical annual maintenance contracts range from AED 500,000 to 5,000,000 for mid-sized facilities. Detailed quotation provided after site assessment.

What is a mechanical completion dossier, and why is it important?

A mechanical completion dossier is the comprehensive documentation package confirming all maintenance work is completed, tested, and verified before plant restart. It includes test reports, NDT results, and as-built documentation essential for safety and compliance.
