ON THE SERIOUS FAILURES OF THE TURBINE SHIPS LAUNCHED ABOUT 1972, 1973

The Marine Engineering Society in Japan, with the help of the four shipping companies concerned, collected data on propulsion-system failures (involving stopping the machinery or reducing ship-speed) that occurred in 15 steam-turbine ships during a period of about 4 years after their launching in 1972/73. The data were statistically analysed with the main objectives of (i) comparing them with earlier data, and (ii) identifying the causes of unreliability so that appropriate countermeasures could be taken. The Authors describe the methods used in the investigation and present and discuss some of the results obtained. It was found inter alia that mean availability had improved (to 0.9975) as compard with previous analyses of ships launched in the 1966-69 period, that 56% of the failures occurred in boiler systems, that leakages of various sorts accounted for many of the failures, and tht the average man-hours required for rectifying a failure had decreased.
