Example 2, Layout diagram for special running<br />

c<strong>on</strong>diti<strong>on</strong>s, engine with FPP, without shaft generator<br />

In th<str<strong>on</strong>g>is</str<strong>on</strong>g> case, the matching point O has been selected<br />

more to the left than in example , providing<br />

an extra engine margin for heavy running operati<strong>on</strong><br />

in heavy weather c<strong>on</strong>diti<strong>on</strong>s. In principle,<br />

the light running margin has been increased for<br />

th<str<strong>on</strong>g>is</str<strong>on</strong>g> case.<br />
