Machinery Torsional Issues in Pipeline Stations
By Amin Almasi, Engineer Pipeline compressor trains and pipeline pump trains are the backbone of gas pipelines. The torsional issues and problems reported for pipeline machineries, such as gas compressor trains and pump trains, can sometimes cause operational problems, even damages or failure. Tools such as advanced modeling and modern simulation programs are employed to optimize the machinery trains in pipeline stations. These trains should meet the highest efficiency and the proper flexibility in the operation. The results of various studies should be used to assess and manage the risk of any mechanical, operational, control, and electrical i
