- Tasks Included:
- The design required civil, architecture, structural, electrical, instrumentation, control, P&ID development, and piping tie-ins for process facilities to accommodate an eventual build-out to 250 MMSCFD at 1440 psig using electric driven compressor units.
- Process Simulation and Design
- Construction Documents - Civil, Structural, Mechanical, Piping, Electrical, Instrumentation and Automation
- Equipment Specification
- Design Criteria
- 230 kV Substation Layout
- Design of a New Power Control Building to House the 4.16 kV Switchgear
- Medium Voltage (MV) Motor Starters, Duct Bank Routing, Grounding Design, Equipment Layout & Piperack Desig, Cable Trays and Conductor Selection
- The station was designed to accept 100 psig gas at the pig receiver, dehydrate it to 5 pounds water per MMSCF, compress it to 1440 psig using gas-fired compressors, and discharge it through a meter at a rate of 50 MMSCFD to the sales gas pipeline.
- The initial design phase included ancillary slug catchers, the fuel gas system and a condensate tank farm.
- The electrical engineering design included transformer sizing to operate up to five (5) 7500 hp induction motors (to drive reciprocating compressors) and two (2) 1250 hp induction motors (to drive reciprocating compressors). Substation layout allowance for future expansion of the facility was a requirement.
- Motor starting analysis was conducted using the Electrical Analyzer Transient Program (ETAP) to evaluate across the line and soft start options for the 7500 hp motors.
