The four destroyers of the Canadian Armed Forces DDH 280 Class have, since commissioning, accumulated a diverse spectrum of operational experience in widely varied geographical theatres ranging from the Tropics to the Arctic and from the Western Atlantic to the Mediterranean. A technical narrative is presented that confirms the original decision to opt for gas turbine propulsion and discusses some of the more significant problems encountered. Areas are highlighted where further system and component development is necessary in the DDH 280 Class in order to maximize the advantages of the aero-derivative gas turbines as a prime mover in our Naval Ships.

Most gas turbine generators rely on an automatic-engaging, free-wheel clutch to connect a starting motor to accelerate the gas turbine generator from zero to some intermediate speed to enable ignition and then provide torque assistance to a higher speed until the gas turbine is self-sustaining. The U.S. Navy has used various designs of starter motors and clutches for its gas turbine fleet. In addition, there has been a requirement to periodically borescope each gas turbine, which has necessitated removal of the starting system and clutch assembly in each instance. This paper examines the U.S. Navy experience with starting clutches and provides details of the development and testing of a synchronous-self-shifting clutch with an additional, stationary, manual turning feature to provide very slow and precise gas turbine rotor rotation for borescope purposes. This paper also gives details of the installation of the first two prototype clutches on the USS Ramage, DDG 61, operating experience for approximately four years, and possible future installations of this type of clutch in U.S. Navy gas turbine generator sets.

The Spruance (DD-963) Class destroyers are the first all-gas turbine powered combatant ships in the US Navy. The first of the 30-ship class entered Navy operational service in September 1975. This paper presents the operational experience of the LM2500 Gas Turbines and the propulsion system from that time to the present. It includes experience obtained from all Spruance class destroyers now and soon-to-be commissioned.

Topping cycle cogeneration plants, consisting of a relatively small gas turbine generator (3–5 MW) and a supplementary fired heat recovery steam generator designed to maximize steam production, are becoming a very attractive system design. Special burners designed to fire into water wall furnaces can add substantial steam production capability to the system in a very efficient manner, utilizing the oxygen available in the turbine exhaust. This paper examines recent operating experience at two U.S. installations, using gas turbines rated at 3.3 MW (Iso) and 4. 8 MW (Iso). Gas fired burner designs are presented. Performance parameters such as response to load, maximum steam production, burner rangeability, and emissions of NOx and CO are discussed.

This article discusses the importance of gas turbines, centrifugal compressors and pumps, and other turbomachines in processes that bring natural gas to the end users. To be useful, the natural gas coming from a large number of small wells has to be gathered. This process requires compression of the gas in several stages, before it is processed in a gas plant, where contaminants and heavier hydrocarbons are stripped from the gas. From the gas plant, the gas is recompressed and fed into a pipeline. In all these compression processes, centrifugal gas compressors driven by industrial gas turbines or electric motors play an important role. Turbomachines are used in a variety of applications for the production of oil and associated gas. For example, gas turbine generator sets often provide electrical power for offshore platforms or remote oil and gas fields. Offshore platforms have a large electrical demand, often requiring multiple large gas turbine generator sets. Similarly, centrifugal gas compressors, driven by gas turbines or by electric motors are the benchmark products to pump gas through pipelines, anywhere in the world.

The two year operating results of the open cycle-gas turbine propulsion plant in the John Sergeant are given with reference to the actual performance, economy, and durability of the components of this marine drive. The operational records show that this type engine can compete favorably with conventional propulsion systems. Similarly, the operating results of the free piston gas-turbine propulsion plant in the William Patterson are given with limited operational experience at this time. The free-piston-installation operating record is submitted as preliminary.
