As part of sustaining current oil production & achieving 70 MBOPD in ADCO’S shah Field, Located 180 KM South- West of Abu Dhabi city, 8 No’s New ESP Wells will be drilled over the period 2015 – 2016. Electrical Power Supply has to be provided near the Well head to run Electrical Submersible Pumps (ESPs), Container mounted Substations (called Power Skids) will be provided by other contractors. And for this purpose these wells shall be Powered from the Existing 33KV Overhead line network. Through this, a New Spur lines to be constructed under this project

3. Scope
Date: - 13/7/2015
The construction of Eight new tap-off 33 KV overhead lines in Shah Field to provide power supply for new 8 nos. ESP (Electrical submersible pump) wells to be drilled out of the following wells & 1 No 33KV overhead line Link between (Sy-80 & Sy-15) also mentioned below:
Sy-85, Sy-86, Sy-87, Sy-88, Sy-89, Sy-90, Sy-91, Sy-92,
OHL Link (Sy-80 & Sy-15).

4. Scope of work
Carry out all necessary modifications for tapping-off from the existing overhead lines through the most practical shortest route.
Date: - 13/7/2015
The Scope of work under this project shall be implemented based on specifications, technical schedules, existing Overhead Line field layout & typical (sample) drawings. Cobra scope of work shall include but not limited to the following.
8
Provision of Topographical (as minimum for every angle pole structure) Survey for routing the main 33 KV overhead line, including line profile & pole spotting.
Extension of overhead line to Power Skid location including supply, installation of overhead line materials such as Wooden poles, Switches, Arrestors, 33KV ACSR Conductors, OPGW, FOC, Cross arms, Stay wires etc. Including all necessary materials for erection, testing & pre-commissioning, completion & warranty of the 33 KV overhead line (Single Circuit). The extended line shall be started at the Tap-off Point & shall end with terminal Pole (G1 Type). 100 Meter away form the Power Skid location ( to be co-ordinated with ADCO). The oil well will be approximately 50-100 Meter away from the Power Skid.
The line route shall be subject to ADCO approval. Each extended line will be started with an Line Isolator Switch with
Earth Switch & Ends with Fused Switch with Earth Switch.
