\nIt is an alternator which is driven by main propulsion propeller shaft through clutch and gearing, especially those sailing for long period at constant ship speed.
\nIt can be used at sea when M\/E is running on full speed. It is capable for load<\/p>\n
\n1) Lloyd\u2019s register would regard a shaft generator as a service main generator, if ME is intended to operate at constant speed (CPP)
\n2) If ME does not operate at constant speed, shaft generator would be disregarded as a service main generator, and at last 2 other independent generators would be required<\/p>\n
\n1) Full generator capacity is available within 60 ~ 100 % of normal speed
\n2) More suitable for shaft with CPP, (constant shaft sped and variable blade pitch)<\/p>\n
\n01) Saving in fuel cost is main advantage
\n02) Saving in LO consumption, repair and maintenance cost due to reduced main generator\u2019s running hours
\n03) Reduction in noise, space and weight, capital saving by reduction of numbers and ratings of main generators<\/p>\n
\n01) Reduction in ship speed
\n02) Problems can rise to maintain electrical supply, during emergency manoeuvring astern
\n03) Increase in capital cost<\/p>\n
\n01) Fuel consumption is saved
\n02) Lower running and maintenance cost
\n03) Lower noise level in ER
\n04) Simple and most compact installation
\nVarying speed of ME, driving a fixed pitch propeller, can be converted by variable gear ratio, to provide constant Generator speed.<\/p>\n","protected":false},"excerpt":{"rendered":"
