Example 2:
Special running conditions. Engine coupled to xed pitch propeller (FPP) and without shaft generator
M Specied MCR of engine
S Continuous service rating of engine
O Matching point of engine
A Reference point of load diagram
MP Specied MCR for propulsion
SP Continuous service rating of propulsion
Point A of load diagram is found:
Line Propeller curve through matching point (O)
is equal to line 2
Line 7 Constant power line through specied MCR (M)
Point A Intersection between line and 7
Example 2, Layout diagram for special running
conditions, engine with FPP, without shaft generator

In this case, the matching point O has been se-
lected more to the left than in example , provid-
ing an extra engine margin for heavy running op-
eration in heavy weather conditions. In principle,
the light running margin has been increased for
this case.
