Holland Engineering, Inc. (HEI) provided engineering design services to Great Lakes Gas Transmission Company’s two separator addition projects. A new 9 foot, 4 inch diameter vertical gas separator with by-pass piping will be installed in series with an existing gas separator at the Deward Meter Station located in Crawford County, Michigan. In addition, a new 5 foot, 8 inch diameter horizontal gas filter separator will be installed at the Farwell Compressor Station located in Clare County, Michigan.
The design entailed modifications to existing compressor station piping to accommodate the addition of the separators, as well as the design of the foundations for the two separators. Holland Engineering’s design also included hookup of all the necessary instrumentation for the vessels and routing of piping for the separator dump lines. Due to space limitations, an existing liquid storage tank at Farwell had to be relocated and a new foundation design incorporated at this site.
All required instrumentation was wired and routed back to the existing RTU at the instrumentation/control buildings. Since instrument air was not available at Deward, a new gas conditioner system was designed to provide instrument gas for the separator’s level controller and over pressure protection devices.
Holland Engineering provided the bid and construction drawings and the contractor’s scope of work for both projects. Construction began on October 13th with Deward scheduled to be completed by the end of December 2011 and Farwell by the end of January 2012. HEI was pleased for the opportunity to be involved with both of these projects.
