TABLE OF CONTENTS In endurance and Fuel Consumption trials, the vessel is run at Maximum Continuous Rating (MCR) power for a fixed duration, say 6 24 h. During this period of time, the following information is measured and recorded:
Fuel consumption in kg/kW hour.
Propeller and Engine rpm.
Indies ted power (P I) within the Engine Room.
Feed water used.
Engine oil pressures and temperatures.
Gearbox oil pressures and temperatures.
Engine water temperatures.
Fuel water temperatures.
Auxiliary units, to verify no presence of overheating.
Monitoring of electrical gear units performance to required standards.
The following matters are the responsibility of the Engine Room staff:
On making a group of runs at a given speed, the original engine settings used when first approaching the measured distance should be rigorously maintained throughout the group. No adjustments should be made when turning about for the return runs.
When altering propeller shaft revolutions or propeller pitch for a new group, the new settings should be made as soon as possible after completing the readings and certainly before finally turning to approach the measured mile itself. Again, they should remain unaltered throughout the group.
Engine-control settings: In current practice, automatic speed governors ensure constant rpm during each group of runs. Where governors are not fitted, the following precautions should be taken:
Diesel machinery: The fuel-control setting should be left unaltered throughout the runs of a particular group.
Steam Turbine machinery: It is essential that the manoeuvring valve settings should...
