Abstract
As part of Define stage study of new oil producing facilities, it was recommended by Asset owners to reduce CAPEX (Capital Expenditure) and OPEX (Operating Expenditure) by
Designing new facilities to have maximum synergy with existing oil trains.
Utilize the spare capacity of existing oil and gas processing trains.
Achieve ZERO / minimize shutdown of the existing facilities.
Adequacy study for existing facilities was carried out and it was concluded that spare capacity of Oil processing trains are adequate however existing LP (Low Pressure) /MP (Medium Pressure) Compressor trains (3 × 50%, 2 operating + 1 standby) had bottlenecks. Therefore, it was recommended to add the new LP / MP (2 × 100%, 1 operating + 1 standby) train parallel to the existing LP/MP Compressor trains.
Further Define stage Adequacy Report also recommends addressing existing issues during Execute stage:
Issues related to load sharing controller of existing compressors along with new load sharing required for new compressors.
For major modification required in piping network, Tie-ins, and pipe routing.
Address design, safety & constructability constraints.
All the above are triggers for escalation of shutdown durations, project cost and major loss of revenue for Asset owners.
