Local Operating Panel
In normal operating the engine can be controlled
from either the bridge or from the engine control
room.
Alternatively, the local operating panel (LOP) can
be activated. This redundant control is to be con-
sidered as a substitute for the previous Engine
Side Control console mounted directly onto the
MC engine.
The LOP is as standard placed on the engine.
From the LOP, the basic functions are available,
such as starting, engine speed control, stopping,
reversing, and the most important engine data are
displayed.
Hydraulic Power Supply
The purpose of the hydraulic power supply (HPS)
unit is to deliver the necessary high pressure
hydraulic oil flow to the Hydraulic Cylinder Units
(HCU) on the engine at the required pressure (ap-
prox. 300 bar) during startup as well as in normal
service.
In case of the STANDARD mechanically driven
HPS unit, at start, one of the two electrically
driven start-up pumps is activated. The start¬up
pump is stopped 25 seconds after the engine
reaches 15% speed.
The multiple pump configuration with standby
pumps ensures redundancy with regard to the
hydraulic power supply. The control of the engine
driven pumps and electrical pumps are divided
between the three ACUs.
The high pressure pipes between the HPS unit
and the HCU are of the double-walled type, hav-
ing a leak detector (210 bar system only). Emer-
gency running is possible using the outer pipe as
pressure containment for the high pressure oil
supply.
The sizes and capacities of the HPS unit depend
on the engine type. Further details about the HPS
and the lubricating oil/hydraulic oil system can be
found in Chapter 8.
