This paper presents a brief history of RB211 operation from initial use in 1974 to present day tracing progressive uprating of original units from 22,000 horsepower to today’s 35,000 horsepower installations.

Problems associated with continuous operation are identified and the solutions discussed.

The maintenance philosophy that has evolved at TransCanada PipeLines to meet specific operational requirements is described, as well as maintenance techniques jointly developed to carry out the program. The merits of an Operator staffed repair base are described. TCPL’s RB211 operating costs per fired hour on a historical basis are summarized.

RB211 performance retention on the TCPL system is described, along with methods and modifications used to minimize or recover performance deterioration.

Finally, future trends in condition monitoring, modular maintenance, and future upgrade possibilities of older standards of the RB211 are discussed.
