Upgrading & Tie-in New Wells into the Existing Cathodic Protection System
Reference: MTC-19/2020 7/19/2020, Location: Africa
Category: Offshore Construction
Scope of Work
The company announces its need for Upgrading and Tie-in new wells into the existing cathodic protection system (Nafoora) Turnkey project Project no P-22.
Description:
- reinstating the Cathodic Protection (C.P.) to a number of wells to the northeast of main areas of exploratory wells, namely “K pool”, “L pool” & “O pool”, (V & Y). It is proposed now that the individual well casings, flow lines, satellites, trunk lines, and GOSP (as applicable) be protected by transformer rectifiers instead of the existing vandalized Solar Energy Units (SEUs). Where feasible, four (4) wells shall be protected by one (TR).
- reinstating Cathodic Protection for Fajr Field (GOSP-8) facilities. Drill & case new DGBs and install new “MMO” anodes firmly secured to dual jacketed cables with a double compression crimp. All (9) TRs be refurbish, all AJBs be replaced. Checking I/Fs & Spark gaps if required.
- Drill & case twelve (11) new DGB around various GOSPs.
- replace sixty (59) lost or defective magnetite anode strings around various GOSPs.
- incorporating (25) newly-drilled Wells around the various GOSPs and previously unprotected structures. It will be necessary to connect these wells to C.P system and install new Insulating Flanges (I/Fs) in the wellheads and flow lines where it is possible or new C. P stations are required.
These improvements will: -
- provide Cathodic Protection to the north east of Nafoora Exploratory wells (Existing SEUs system broken).
- provide Cathodic Protection to all facilities in Fajr Field.
- Return back full operation of eleven (11) depleted DGBs.
- Return back full operation of 21 CP stations due to (59) defective anodes.
- provide Cathodic Protection to (25) previously unprotected Wells.
