Opposed Piston (OP) The Fairbanks Morse Opposed Piston (OP) engine has been designed and developed for a wide array of electrical power generation and heavy industrial applications. You will find OP engines propelling ships, driving locomotives, powering natural gas compressors, running chillers and pump drives, and producing electricity in a variety of marine and stationary applications. OP engines have even provided standby power for the country's most critical applications, including take-home power for nuclear submarines, emergency reactor cooling in nuclear power facilities, and emergency power for vital life support and telecommunications networks. This high efficiency and low emission engine results in economic power generation. When equipped with Enviro-Design®, dual-fuel technology, the OP engine is ideally suited for low-cost electric power production and is one of the most efficient low-emission natural gas engines available in the industry.
