The review summarises developments since the early 1960s in a table giving the main particulars of 17 designs from IHI, General Electric, (GE's MST)21) to 80,000 hp (Kawasaki's advanced steam power plant of 1974). Since the revival of reheat in 1966, 23 ships with reheat have been built, 19 of them in Japan; most owners, however, have opted for non-reheat plant. Trends in steam-turbine plant since the 1973 oil crisis are then considered. Some typical developments discussed include GE's MST-23 and Stal Laval's VAP plant (two high-performance plants) and Mitsubishi's T-MAP and GE's MST-21 (both with a relatively small output and featuring easy operation). High-performance plant and easy-operation plant, in which the respective fuel rates sought seem to be about 170 and 190 g/hp-hr, should show some increase in demand in the future. Modern turbine design is considered with particular reference to reheat, and different configurations of reheat turbine plant developed by the various manufacturers, and including some still under development, are described and discussed. Boiler design is similarly considered, and current and future developments are discussed under the headings: (i) High-Temperature and High-Pressure Reheat Boiler. Developments in the drives for feed-water pumps and turbo-generators are also discussed. The reliability of steam plant is considered on the basis of an analysis conducted by Nippon Kaiji Kyokai on the sources of troubles and failures in the installation, and there is a brief discussion on shipboard fuel-treatment to meet the demands of future high-viscosity fuels.
