Boabat Alnoor Company (BN) delivered the turnkey Engineering, Procurement, and Construction (EPC) contract for the RATAWI AGUP Phase 1 transmission line project in Basra, Iraq, for TotalEnergies EP Ratawi Hub (TEEPRH)[cite: 8]. The infrastructure development establishes a direct, high-capacity electrical link from the Iraqi National Grid to Central Processing Facility 1 (CPF1), securing stable and reliable utility power for critical upstream facilities within the Ratawi Oil Field[cite: 8].
Scope
The contract delivered a full EPC transmission and substation package across challenging desert oilfield terrain[cite: 8]:
- Route alignment, detailed engineering, and foundation design accommodating multiple oilfield pipeline, road, and utility crossing corridors[cite: 8].
- Turnkey procurement and delivery of high-capacity ACCC conductors, galvanized steel lattice structures, composite insulators, and high-voltage line hardware[cite: 8].
- Civil foundation construction, reinforced concrete works, and soil stabilization across soft desert right-of-way sections[cite: 8].
- Assembly and erection of heavy-duty suspension, angle, and tension steel lattice towers[cite: 8].
- Specialized tension stringing, sagging, and termination of advanced composite-core ACCC Casablanca conductors[cite: 8].
- Site installation, connection, and tie-in works for a high-capacity 31.5 MVA, 132/33 kV mobile substation[cite: 8].
- Execution of the critical 132 kV T-Tap transmission connection to interface directly with the national transmission grid[cite: 8].
- Comprehensive testing, pre-commissioning, high-voltage insulation checks, and energized network handover[cite: 8].
Key Deliverables & Advanced Technology
The project highlights the implementation of high-efficiency, advanced conductor technologies in oil and gas infrastructure[cite: 8]:
- Transmission Line: Approximately 6 km of 33 kV overhead transmission line (OHTL)[cite: 8].
- Advanced Conductor: High-performance ACCC® Casablanca Conductors manufactured by EMTA under CTC Global license, delivering high ampacity and minimal thermal sag over pipeline corridors[cite: 8].
- Tower Structures: 26 hot-dip galvanized steel lattice towers, comprising engineered suspension, heavy-angle, and terminal tension configurations[cite: 8].
- Substation & Grid Tie-In: Installation and integration of a 31.5 MVA, 132/33 kV mobile substation and complete 132 kV T-Tap line tap-off connection[cite: 8].
- Hardware & Insulation: Certified transmission line hardware fittings supplied by Sicame and high-spec outdoor composite insulators supplied by SolidCure[cite: 8].
How it is delivered
Constructed in close coordination with TotalEnergies operational teams, works were executed under stringent international oilfield HSE regulations and strict permit-to-work (PTW) protocols[cite: 8]. Tension-stringing operations over active hydrocarbon pipelines and crossing corridors were managed with engineered protection scaffolds to ensure zero risk to surrounding live assets[cite: 8].
Rigorous quality controls—including conductor core verification, torque checks, insulator testing, and substation protection scheme validation—ensured flawless energisation and immediate grid synchronization[cite: 8].
