Auxiliary Propulsion System/Take Home System
From time to time an Auxiliary Propulsion System/
Take Home System capable of driving the CP pro-
peller by using the shaft generator as an electric
motor is requested.
MAN Diesel can offer a solution where the
CP propeller is driven by the alternator via a
twospeed tunnel gear box. The electric power is
produced by a number of GenSets. The main en-
gine is disengaged by a clutch (RENK KAZ) made
as an integral part of the shafting. The clutch is in-
stalled between the tunnel gear box and the main
engine, and conical bolts are used to connect and
disconnect the main engine and the shafting.
See Figure 4.04.03.
A thrust bearing, which transfers the auxiliary pro-
pulsion propeller thrust to the engine thrust bear-
ing when the clutch is disengaged, is built into the
RENK KAZ clutch. When the clutch is engaged,
the thrust is transferred statically to the engine
thrust bearing through the thrust bearing built into
the clutch.
To obtain high propeller efficiency in the auxiliary
propulsion mode, and thus also to minimise the
auxiliary power required, a twospeed tunnel gear,
which provides lower propeller speed in the auxil-
iary propulsion mode, is used.
The twospeed tunnel gear box is made with a
friction clutch which allows the propeller to be
clutched in at full alternator/motor speed where
the full torque is available. The alternator/motor is
started in the declutched condition with a start
transformer.
The system can quickly establish auxiliary propul-
sion from the engine control room and/or bridge,
even with unmanned engine room.
Reestablishment of normal operation requires
attendance in the engine room and can be done
within a few minutes.
