Observations:
ME PMI
Engines poorly balanced, often outside recommended deviation limits
Observations:
Engines operated with low Pmax level
Result:Increased fuel oil consumption & CO2 emissions
1 bar increase in average Pmax => 0.20 - 0.30 g/kWh decrease in fuel oil consumption
Result:
g g p
Action:Action:Adjust engine continuously to best operating conditions

CoCoS-EDS
Two versions available: CoCoS-EDS ME Basic: Mandatory for all ME, ME-C and ME-B engines CoCoS-EDS Full version: Optional for all MAN Diesel 2-stroke engines
Both versions shares the same system software that makes monitoring, adjustment and trouble shooting of the engine much more efficient.
The main difference is the configuration of the software and the interface towards other systems (e.g. Alarm and monitoring system AMS etc)
up to 80 080 kW
