A review of the year which saw: increased popularity of small bore low speed engine designs, particularly the latest long-stroke models; the new three-cylinder Doxford in service; constant pressure turbocharging adopted by B & W for its low speed range and Mitsubishi's development of a new engine with a single-stage c.p. turbocharing system; details of a 600 mm bore short-stroke project at GMT; still a market in big ro-ros and container ships for the large bore low speed engines; and steam-to-diesel conversions giving a boost to third-generation medium speed engines. At the time of writing it is not possible to define the exact degree of diesel dominance in 1978 but it will be surprising if the 1977 figure is not topped: in that year diesel engines accounted for 83.6 percent of the total horsepower installed in ships of 2,000 tonne d.w. and above (63.7 percent being low speed engines and 19.9 percent medium and high speed designs). Steam turbines accounted for just over 15 percent of the remaining horsepower and gas turbines about 1.5 percent.
