The paper discusses the development and use of mobile compressor stations to achieve maximum utilization of pipeline facilities by affording protection against outage of base-load compression equipment. The design approach makes use of an aircraft-type turbine as the hot gas generator due to its high power-to-weight ratio and suitability for trailer mounting. Comparative cost data showing the feasibility of the mobile concept are presented, together with details of capital cost and operating, costs. The operating record for two mobile units is outlined, and a program for future operation is presented.
