Wartsila Generator Manual
MONITORING AND CONTROL When the plant is in operation, personnel is either present at site, or, if the plant is remotely controlled, on-call personnel should be stationed close enough to reach the plant at short notice when needed. The control system records alarms and events in the workstation. The operators make daily checks around the plant to check local meters, drain points, vibrations, etc. Abnormal conditions requiring prompt operator efforts are noted by alarms, which are indicated by sound and light signals. Engine alarms may also be indicated by status and alarm annunciator lights in the engine hall. Replacement of parts (examples) Piston rings, main gas admission valves, ignition coils, pre-chamber tips, pre-chamber valves, spark plugs Spark plugs, gas filter cartridges, oil mist detector filters, expansion bellows, flexible pipe connections Piston rings small end bearing big end bearing, valves, turbocharger bearings, charge air coolers, ignition coils, spark plugs Turbocharger rotor, charge air bellow, spark plugs, gas filter cartridges, oil mist detector filters, expansion bellows, control system modules, drive electronics.
Wartsila Engines
Figure 2.3 Maximum load increase rates for variable speed engines Loading of Wartsila 38 engines variable speed If minimum smoke during load increase is a major priority, slower loading rate than in the diagram can be necessary below 50% load. In normal operation the load should not be reduced from 100% to 0% in less than 15 seconds. When ab- solutely necessary, the load can be reduced as fast as the pitch setting system can react (overspeed due to windmilling must be considered for high speed ships).
