Local Operating Panel (LOP)<br />
In normal operating the engine can be c<strong>on</strong>trolled<br />
from either the bridge or from the engine c<strong>on</strong>trol<br />
room.<br />
Alternatively, the LOP can be activated. <str<strong>on</strong>g>Th<str<strong>on</strong>g>is</str<strong>on</strong>g></str<strong>on</strong>g> redundant<br />
c<strong>on</strong>trol <str<strong>on</strong>g>is</str<strong>on</strong>g> to be c<strong>on</strong>sidered as a substitute<br />
for the previous Engine Side C<strong>on</strong>trol c<strong>on</strong>sole<br />
mounted directly <strong>on</strong>to the MC engine.<br />
The LOP <str<strong>on</strong>g>is</str<strong>on</strong>g> as standard placed <strong>on</strong> the engine.<br />
From the LOP, the basic functi<strong>on</strong>s are <str<strong>on</strong>g>available</str<strong>on</strong>g>,<br />
such as starting, engine speed c<strong>on</strong>trol, stopping,<br />
reversing, and the most important engine data are<br />
d<str<strong>on</strong>g>is</str<strong>on</strong>g>played.<br />
C<strong>on</strong>trol Network<br />
The MOP, the backup MOP and the MPCs are<br />
interc<strong>on</strong>nected by means of the doubled C<strong>on</strong>trol<br />
Network, A and B respectively.<br />
The maximum length of C<strong>on</strong>trol Network cabling<br />
between the furthermost units <strong>on</strong> the engine and<br />
in the Engine C<strong>on</strong>trol Room (an EICU or a MOP) <str<strong>on</strong>g>is</str<strong>on</strong>g><br />
60 meter.<br />
Should the layout of the ship make l<strong>on</strong>ger C<strong>on</strong>trol<br />
Network cabling necessary, a C<strong>on</strong>trol Network<br />
Repeater must be inserted to amplify the signals<br />
and divide the cable into segments no l<strong>on</strong>ger than<br />
60 meter. For instance, where the Engine C<strong>on</strong>trol<br />
Room and the engine room are located far apart.<br />

Hydraulic Power Supply (HPS)<br />
The purpose of the HPS unit <str<strong>on</strong>g>is</str<strong>on</strong>g> to deliver the<br />
necessary high pressure hydraulic oil flow to the<br />
hydraulic cylinder units (HCU) <strong>on</strong> the engine at<br />
the required pressure (approx. 200 bar) during<br />
start�up as well as in normal service.<br />
As hydraulic medium, normal lubricating oil <str<strong>on</strong>g>is</str<strong>on</strong>g><br />
used, and it <str<strong>on</strong>g>is</str<strong>on</strong>g> in the standard executi<strong>on</strong> taken<br />
from the main lubricating oil system of the engine.<br />
The HPS unit can be driven either mechanically<br />
from the engine crankshaft, see Fig. 6.0 .02.<br />
The HPS unit c<strong>on</strong>s<str<strong>on</strong>g>is</str<strong>on</strong>g>ts, if mechanically driven, of:<br />
• A crankshaft driven step�up gear<br />
• Three or four engine driven pumps<br />
• Two electrically driven pumps<br />
• An automatic filter with a redundancy filter<br />
• A safety and accumulator unit.<br />
The multiple pump c<strong>on</strong>figurati<strong>on</strong> with standby<br />
pumps ensures redundancy with regard to the<br />
hydraulic power supply. The c<strong>on</strong>trol of the engine<br />
driven pumps and electrical pumps are divided<br />
between the three ACUs.<br />
The high pressure pipes between the HPS unit<br />
and the HCU are of the double walled type, having<br />
a leak detector. Emergency running <str<strong>on</strong>g>is</str<strong>on</strong>g> possible<br />
using the outer pipe as pressure c<strong>on</strong>tainment for<br />
the high pressure oil supply.<br />
The sizes and capacities of the HPS unit depend<br />
<strong>on</strong> the engine type. Further details about the lubricating<br />
oil/hydraulic oil system can be found in<br />
