South Annajma Export Pipeline System

Project Description

Star Oil Operating company is a newly formed petroleum company to carry out the development of block 17, which covers an area of 22,185 m² in south Kordofan. The development’s objective was to transport 60,000 BOPD of crude oil, that is coming from the early production facility “EPF” at Annajma area to the Central Processing Facility “CPF” at Fula area. To meet this target, 43km – 12’’ underground pipeline was constructed to transfer 10,000 Barrels of Petrol per Day (BOPD), in its first stage to be increased gradually to 60,000 BOPD.

Star Oil awarded the EPCC project to “Petroneeds Services International”, which entrusted ECG with the services of design, detailed engineering and procurement documentation. The project comprised head pump station at Annajma area; two metering skids, one on each end of the pipeline; pigging facilities at both ends of the pipeline; emergency power generation; all related facilities for safe operation and control of the pipeline; service road of approximately 4.8 km including a seasonal river crossing, in addition to tie-in with Petro- Energy CPF at Fula.

Project design services included process and pipeline dynamic simulation, Piping and Instrumentation Diagram (P & ID), Piping Flow Diagram (PFD), Utility Flow Diagram (UFD), safeguarding philosophy; pump station design (plot plan, equipment layout, pipe supports and general arrangements); pipeline design (alignment sheets, crossing details, etc), Instrumentation & Control (I & C); stress analysis; cathodic protection; electrical (power, lighting, earthing); and HAZOP study.

Also, a fibre optic cable was designed to be routed along the side of the pipeline for the transfer of control data.
