New Slug Catcher at Underground Gas Storage Facility

New Slug Catcher at Underground Gas Storage Facility

Orbital provided engineering and design services for the installation of a new four vessel slug catcher system, associated 5 tank liquid storages, TEG tank and piping at a gas processing facility with underground storage. The design also included modification of the existing pig launcher/receiver and integration into the existing Plant Control System. The slug catcher system has a total 75,000-gallon slug capacity, equating to approximately 1,785 barrels (bbl), with the five-tank farm having a 125,000-gallon liquid storage capacity. Orbital provided full multi-discipline engineering services including conceptual design, process, mechanical, 3D piping, civil, structural, electrical, I&C, procurement support, construction support and commissioning/startup.  Orbital’s services started with a study phase to consider different equipment locations, slug catcher types and vendors. With the preferred option selected Orbital proceeded with the demolition and relocation design, as a separate package was compiled for of an outage to allow for the main phase of construction to take place. The next phase was Detailed Design, which included the necessary drawings, 3D model, specifications, datasheets, calculations and other documents to support installation of the new equipment. To complete the project, Orbital provided start-up support services, as-built drawings and close-out/turnover documentation.
