EPC DGS-N Cable Ladder Installation and 11 kV Power Supply to DGS-N Wells

Project Type

BN PROJECT EXPERIENCE | ELECTRICAL & POWER DISTRIBUTION

Project Overview

BN delivered the complete engineering, supply, installation, testing and commissioning of the galvanized cable ladder system and associated structural supports serving the DGS-N electrical distribution network. The project also included the laying, routing, termination and connection of 11 kV power cables supplying DGS-N wells.

The new cable support infrastructure was engineered not only for the immediate 11 kV well-supply requirements, but also as a durable common route for future MV and HV power circuits originating from DGS-N toward nearby facilities and Hammar Mushrif wells. This future-ready approach provides the field with a robust, accessible and expandable power-routing backbone.

Scope of Work

BN executed the project on a full EPC basis, integrating civil interfaces, structural steelwork, cable management and medium-voltage power installation into one coordinated field solution.

  • Engineering design of cable ladder routes, support spacing, steel structures, elevations, interfaces and road-crossing arrangements.
  • Supply and installation of heavy-duty hot-dip galvanized cable ladders, trays, fittings, bends, vertical risers and accessories.
  • Design, fabrication and installation of special galvanized structural-steel supports engineered to carry the initial cables and additional future MV/HV circuits.
  • Construction of elevated cable-ladder bridges over internal DGS-N roads to maintain vehicle clearance and continuous cable routing.
  • Installation, laying, dressing, identification, testing, termination and connection of 11 kV cables feeding DGS-N wells.
  • Coordination of cable routes with existing plant equipment, roads, fences, electrical facilities and operating-area requirements.
  • Inspection, testing and commissioning of the completed cable support and 11 kV power distribution installation.

Engineered Galvanized Cable Support System

A key feature of the project was BN’s purpose-designed galvanized steel support system. Rather than treating the cable ladder as a temporary or single-service installation, BN engineered the route as permanent field infrastructure with sufficient structural capacity, access and usable ladder space for future expansion.

BN Capability in Cable Trays & Ladders

BN has practical EPC capability for complete cable-management systems in oil and gas facilities, from route development and load assessment through fabrication, installation and final cable pulling. Our teams can deliver customized support arrangements where standard catalogue supports are not suitable for field conditions, plant interfaces or future cable-loading requirements.

  • Heavy-duty hot-dip galvanized cable ladders and trays suitable for outdoor oil & gas environments.
  • Custom galvanized structural frames, portal supports and multi-tier cable support systems.
  • Road-crossing cable bridges and vertical rise/drop structures with engineered clearances.
  • Multi-level arrangements capable of segregating MV, HV, LV, control and communication circuits where required.
  • Integrated design considering cable bending radius, pulling access, support loads, maintenance access and future expansion.
  • Field erection, alignment, bolting, grounding/bonding interfaces and quality inspection by experienced BN teams.

11 kV Power Supply to DGS-N Wells

The installed ladder network provides the physical backbone for the 11 kV circuits feeding DGS-N wells. BN executed the MV cable installation with controlled routing, segregation, support, dressing and connection practices appropriate for an operating oil-field environment.

By consolidating the well feeders on an engineered above-ground ladder system, the project improves cable accessibility, visual inspection, maintenance and future extension while reducing dependence on repeated excavation for new circuits. The overhead bridge sections preserve internal road access while maintaining a continuous and protected cable route.

Technical & Operational Value

  • Reliable 11 kV distribution route for DGS-N well power supply.
  • Expandable infrastructure for future DGS-N outgoing MV/HV feeders and Hammar Mushrif well connections.
  • Improved cable accessibility for inspection, maintenance and fault response.
  • Reduced future civil works and excavation through provision of spare ladder capacity.
  • Robust outdoor galvanized construction designed for long-term field service.
  • Organized routing that improves cable management, plant appearance and maintainability.

Construction, Installation & Quality Execution

The project required close coordination of surveying, foundation interfaces, structural erection, lifting operations, access equipment and cable installation. BN managed the activities in sequence to maintain safe work fronts and accurate alignment across the long cable corridor and road crossings.

Project Outcome

The completed installation provides DGS-N with a permanent, high-capacity cable routing system supporting both current 11 kV well electrification and the future development of the surrounding power network. The project demonstrates BN’s ability to combine electrical EPC execution with specialized cable-management engineering, structural fabrication and field installation in complex oil and gas environments.

BN delivers complete cable-management solutions - from engineering and structural fabrication to installation, cable pulling, testing and commissioning - engineered for reliability, maintainability and future expansion.
