The technology of marine steam-turbine plant has progressed nearer to "completion"than that of Diesel engines and gas turbines, and, with a few exceptions, there have been no important advances in the technology of the steam-turbine plant over the past ten years. There are now a large number of steamships with NK's MO notation (i.e., engine room unmanned at night), and these automated ships have shown high reliability. However few up-to-date data are available on the reliability of the steam plant in these and other ships, and the Author, of the Ship Research Institute, Tokyo, here presents a recent analysis of the reliability of the plant. The analysis, covering the 12-month period Apr. 1977 to Mar. 1978, embraces 31 ships, 22 of them with the MO notation. Machinery output ranges from 24,000 to 50,000 hp. Ten of the ships have IHI plant, seven have Mitsubishi, twelve have Kawasaki, and two have Stal Laval plant. The ships, of various ages, consist of 29 tankers, a container ship, and an OBO carrier, and the failure information has been obtained from their engine departments. The analysis, which is presented in tabular form, indicates a ship availability figure of above 0.997. The causes of the failures, failure diagnosis, the various factors of influence, and the possibilities of improving reliability are discussed in some detail. Order from BSRA as No. 54,564.
