Project Description
In 2016, Sargent & Lundy was awarded a contract for the engineering and design of a new compressor station. This gas compressor station is a natural gas pipeline transmission station within the company’s pipeline network that receives gas from four pipelines, two belonging to the client and two belonging to an interstate transportation pipeline company, and returns gas to these same pipelines in addition to feeding a local distribution network.
The gas compressor station is a manned, two-plant natural gas compressor transmission station consisting of eight 1,000-horsepower (hp) gas compressor units, four 1,000-hp compressor units, and one 3,000-hp compressor unit in two separate buildings, Plant 1 and Plant 2.
The project replaced two existing compression plants with a third new plant, Plant 3. The overall project is in two phases. Phase 1 added two new compression units installed in a temporary location and connected to the existing facility. These two compression units became operational in fall 2017.
Phase 2 is a completely new standalone gas compression station. The new station has five reciprocating compression units, and is capable of being operated completely unmanned.
The engine compressor package consists of a natural-gas-fired industrial engine (GE Waukesha 12V275GL+) driving five Neuman & Esser industrial high-speed separable reciprocating compressor units rated at 3,750-hp each.
Project Scope
Sargent & Lundy performed the detailed design engineering and support startup/commissioning. The design supported Phase 2 construction in two stages. In Stage 1, the first three compressors were installed and commissioned. The two units from the Phase 1 temporary installation were relocated to the new Plant 3 during Stage 2. The design allows for safe, isolated operation of the first three units during construction of the last two units.
