Engine-performance monitoring systems produced by A.S. Maritek, of Norway, offer considerable savings in machinery operating costs, with payback periods of six months or less. After mentioning some well-known ships equipped with these computerised systems, the article describes the systems and their operation. Each system, whether for Diesel or steam propulsion, is based on a meter that simultaneously measures propeller-shaft torque, thrust and rpm. Developed for motor ships, the Maritek Combustion Analyzer has an engine-room data-logger; information printout includes: cylinder and fuel-injection pressures; m.i.p. and i.h.p.; ignition timing and lag; indications of possible wear and damage; and a bar graph comparing the m.i.p. of the different cylinders. The Maritek Diesel Performance System includes this combustion analyser and also provides data on: turbocharger, boiler and turbogenerator performance; various heat-transfer and heat-balance data; and fuel consumption and air/fuel ratio. For steam ships, the Maritek performance monitor gives continuous reports on power, rpm, torque, thrust, fuel consumption and ship speed; accumulated values can be given for time, distance sailed, and energy consumed. Graphical displays show speed/power or speed/fuel-flow deviations; hull and propeller condition can be found by checking data against reference curves obtained under comparable weather and other conditions.
