Carried out a screening study for a significant gas gathering facility in the UKCS. Located in the Central North Sea the system would be designed to gather gas from a number existing fields through a gathering system comprised of two platforms. Platform configuration would comprise a gathering and compression platforms designed to maintain production from the area for an extended period. A key element of the study was to optimize gathering and export pipe lines configurations along with production throughput; production rate of 900 through 1,300 million standard cubic feet per day were considered. Development and operating cost estimates were generated using our NETCO$TER Cost Evaluation Software.
