Enjaz Al Qimma Oil Services

Design and consulting work with current engineering software, to ASME and API standards.

• FEED and detailed engineering: station layouts and specifications for fixed and mechanical equipment
• Piping stress analysis: loads, pressure and thermal expansion across piping networks, to protect structural integrity
• Shop drawings: detailed drawings for the fabrication workshops and the site teams

Electrical works and plant automation and control systems.

• Installation of flow, pressure, temperature and level instruments, each calibrated in our own workshops
• Laying and termination of high and medium voltage power cables and of control and signal lines, in control panels and junction boxes

The step between finished installation and live operation.

• Loop checking: testing digital and analogue signals between field instruments and the control room
• Pre-commissioning: checking system sequences, testing control valves and verifying automatic alarms before hydrocarbons are introduced

Mechanical and infrastructure work for oil and gas facilities.

• Stations and depots: oil pumping stations, gas compression facilities and produced-water treatment plants
• Steel structures: steel platforms, pipe racks and supports for heavy equipment
• Tie-ins: connecting new wells to existing facilities, planned around ongoing production

Long-distance lines for oil, gas and water across open and desert terrain.

• Right of way: trenching, grading and clearing obstacles along the route
• In-field pipe bending with hydraulic bending machines, so the line follows the ground
• Welding by certified welders, with each joint tested straight away, before backfilling

Cleaning and checking a pipeline after construction or maintenance, before it goes into service.

• Construction pigging: removing construction debris from inside the line
• Caliper pigging: measuring the internal diameter and finding dents or deformation in the pipe wall
• Commissioning: nitrogen purging and drying, so the line is free of moisture

Protection of buried and submerged pipelines against corrosion.

• Field joint coating: epoxy coating of welded joints on site, matched to the factory coating of the pipe
• Cathodic protection: design and installation of impressed-current systems and sacrificial anodes

Large welded steel tanks above ground, for crude oil, light and heavy petroleum products and low-pressure gases.

• Design and fabrication to API 650 and API 620
• Fixed roofs, and floating roofs with double seals that reduce evaporation and emissions

Treatment and protection of welded and exposed steel.

• Post weld heat treatment (PWHT): controlled heating cycles that relieve stress in welded joints
• Sandblasting and industrial coating systems for desert and marine conditions
• Thermal and acoustic insulation: rock wool and cladding on hot and cold piping, to save energy and protect staff from burns

Keeping existing storage tanks sound and preventing leaks.

• Inspection to API 653: non-destructive testing of walls and bottoms to measure plate thickness and find corrosion
• Bottom and annular plate replacement, with the tank raised by synchronised hydraulic lifting

Planned shutdowns and major overhauls of refineries and processing plants.

• Static equipment maintenance: opening, inspecting, cleaning and closing distillation columns, pressure vessels and heat exchangers, then testing them
• Mechanical upgrades and revamping: replacing worn piping components, overhauling main valves and returning production units to design capacity

Planning that keeps a turnaround on schedule and within budget.

• Hour-by-hour schedules built with the critical path method (CPM), matching materials to crews
• Logistics and risk management: heavy equipment and cranes mobilised in advance, with contingency plans for technical risks

Documented tests of systems, vessels and pipelines before they go live.

• Hydrostatic testing with treated water, at pressures above operating limits, to prove welds and tightness
• Pneumatic testing with dry air or nitrogen, for systems that must stay dry
• Certified test packs: pressure readings and inspection charts recorded for every system and handed to the client

Checks that extend the life of equipment and prevent mechanical failure.

• Pressure relief valve (PRV) testing and calibration on test rigs, with certified records
• Inspection of cranes, gantry hoists and lifting tackle such as slings and shackles, with safety certificates

Two specialised packages that extend the asset integrity work.

• OCTG inspection and maintenance: non-destructive testing of drilling, production and casing pipes before they go downhole
• Heat-exchanger retubing: replacing corroded tube bundles, followed by re-facing and hydrostatic testing

Site services that keep a project working.

• Scaffolding designed, erected, inspected and dismantled following OSHA practice
• Hot tapping: connecting to live pipelines under pressure without stopping the flow

Mobilisation, asset care and specialist skills for field operations.

• Mobilisation of engineers, certified welders and automation specialists to remote sites, with heavy machinery and mobile workshops
• Asset management: periodic inspections, structural assessments and preventive maintenance programmes
• Early production facilities (EPF), so clients can produce from new wells and assess reserves before permanent facilities are complete
• Maintenance, calibration and rehabilitation of gas and steam turbines in power generation and compression plants
• QA/QC at every stage from FEED to final performance testing, to ASME and API codes, with every inspection documented
