Case Study of Large Medium Speed Reciprocating Horsepower in Pipeline Applications
This paper is a report to the North American natural gas pipeline market on one companys experience with the GCM34 engine in mainline transmission. These are the first GCM34 engines commissioned in pipeline service representing a trend in North America for the next generation of reciprocating HP in this application. Discussed are reasons a unique skid mounted design was chosen. Energy Transfer will discuss the factors that influenced their decision to replace centrifugal HP with reciprocating HP on existing pipelines. Key drivers for compression decisions include low emissions, high fuel efficiency, availability and durability. This paper presents a case study of a midstream and interstate pipeline companys experience showing actual engine and compressor performance.
