Due to the tight project timelines, various construction locations and several facility delivery dates, the construction was broken down into multiple construction contracts. Because the new facilities are being integrated into existing facilities, elements of the electrical, instrumentation and controls detailed design and engineering were undertaken in-house by APA.
Procurement included tendering and award of procurement orders, and construction and supply contracts.
Engineering and construction considerations
The significant engineering challenge associated with the SWQP reconfiguration has been to ensure that the facilities provide functional and safe operation under the multiple flow regimes possible with the complex arrangement of pipeline systems, multiple flow directions and flow rates required across the SWQP network. Besides the design of the new facilities involved, the engineering also required review and analysis of the existing facilities for functional and safe operation.
The project underwent a significant number of hazard and operability assessments, which were implemented to identify and evaluate risks to personnel or equipment and to ensure efficient operations. Numerous hazard identification assessments and safety integrity level assessments were also employed.
The construction of the new facilities at three sites involved construction activities within existing operating facilities.
