Comprehensive Pipeline Construction Services

Onshore Pipelines

Cross-country pipeline projects for oil and gas transmission are handled across the UAE. Trenching, welding, coating, and backfilling operations are managed by project teams. Environmental protection and minimal disruption to local communities are prioritized throughout construction.

Offshore Pipelines

Specialized marine construction crews and equipment support offshore energy operations. Lay barges and experienced divers perform subsea pipeline installations. Safety remains the priority during every offshore operation, with strict adherence to marine safety protocols.

Pipeline Repair & Rehabilitation

Aging pipeline infrastructure requires regular expert care and maintenance. Inspection, cleaning, and repair of existing pipeline networks extend operational life and prevent costly leaks. Production operations continue with minimal disruption during rehabilitation work.

Tie-in & Connection Works

New pipelines must be connected to existing infrastructure. Hot taps, tie-ins, and final connections are executed with precision. Isolation procedures ensure safety during connection to live lines.

Integrated EPC Capabilities for Pipeline Projects

Turnkey solutions for pipeline projects are delivered through an integrated approach. A multidisciplinary team manages every phase of the project lifecycle, ensuring consistent quality from concept to commissioning.

Engineering & Design

Detailed pipeline designs are created based on soil conditions, operating pressure, flow requirements, and product characteristics. Engineering tools for route optimization, stress analysis, and hydraulic modeling ensure efficient, code-compliant designs. Right-of-way (ROW) planning addresses land access, environmental constraints, and construction logistics.

Material Procurement & Traceability

Steel pipes, fittings, valves, and coatings are sourced from certified mills and suppliers. Material quality is verified against project specifications. Mill test certificates are logged, and full traceability is maintained from procurement through installation.

Pipeline Construction & Field Installation

Certified welders perform pipeline construction using approved welding procedure specifications (WPS). Stringent quality control governs all field activities:
● Trenching & Backfilling: Excavation to specified depth, bedding placement, and controlled backfill with compaction testing.
● Welding: API 1104 standards govern all field welds. Welders are qualified for pipe grades and wall thicknesses.
● Coating & Field Joint Protection: Field joints are coated to match the parent pipe specification. Holiday testing verifies coating integrity.
● NDT & Inspection: 100% of welds are inspected using radiography (RT) or ultrasonic testing (UT). Additional NDT methods, including magnetic particle (MT) and dye penetrant (PT), are applied where specified.

Testing & Pre-Commissioning

Full system integrity is verified before handover:
● Hydrostatic Testing: Pipelines are filled with water, pressurized to test pressure (typically 1.25-1.5× design pressure), and held for the required duration. Pressure and temperature are monitored continuously.
● Pigging: Cleaning pigs remove debris, and swabbing pigs verify internal condition. Gauging plates confirm the internal diameter is clear.
● Drying & Nitrogen Purging: After hydrotest, lines are dried and nitrogen-purged for preservation and safe handover.
● Commissioning & Handover: Final system operation is demonstrated. As-built drawings, test records, NDT reports, and O&M manuals are compiled for client handover.

Standards & Compliance

All pipeline work complies with international codes and UAE regulatory requirements.
● API 1104: Standard for welding pipelines and related facilities
● ASME B31.3 / B31.4 / B31.8: Process piping, liquid transportation, and gas transmission codes
● ISO 9001 & ISO 45001: Certified quality and safety management systems
● ADNOC Specifications: Experience working with ADNOC Onshore and Offshore standards
● UAE Regulatory Requirements: Compliance with local environmental and safety regulations

Safety-Driven Pipeline Construction

Safety Culture

Every workday begins with safety briefings and hazard identification. Structured safety procedures govern all pipeline construction activities. Permit-to-work systems control access and high-risk tasks.

HSE Training

All personnel hold valid HSE certifications, including basic safety induction, permit-to-work authorization, confined space entry, working at heights, and emergency response procedures.

Environmental Protection

Waste control and spill prevention are implemented across every construction site. Clean, protected project areas are maintained from start to completion. Trenching and excavation plans include measures to prevent soil erosion and protect groundwater.

FAQs

What welding standards apply to oil and gas pipelines?

API 1104 is the primary standard for welding pipelines and related facilities. Welders must be qualified to this standard for the specific pipe grades and wall thicknesses being welded.

What is pipeline pigging and why is it important?

Pigging involves inserting devices into the pipeline for cleaning, inspection, or internal diameter verification. Smart pigs (intelligent pigs) carry sensors to detect corrosion, cracks, or other defects before they cause failures.

How long does pipeline construction typically take?

Project duration depends on length, terrain, and complexity. A 10-20 km onshore pipeline may take 6-12 months from mobilization to commissioning. Detailed schedules are provided during bidding.

What is the cost range for pipeline construction in the UAE?

Costs vary significantly based on pipe diameter, length, terrain, and specifications. Typical ranges are AED 500,000-1,500,000 per km for onshore pipelines. Detailed quotation provided after route assessment.

Is hydrotesting mandatory before pipeline handover?

Yes. Hydrostatic testing is mandatory to verify pipeline integrity. Pipelines are filled with water and pressurized to 1.25-1.5 times design pressure for the required duration to confirm no leaks or failures.

Is hydrotesting mandatory before pipeline handover?

Yes. Hydrostatic testing is mandatory to verify pipeline integrity. Pipelines are filled with water and pressurized to 1.25-1.5 times design pressure for the required duration to confirm no leaks or failures.
