The Mega-Guard Tunnel Thruster Control
System (TCS) fully automates from bridge
the control of the tunnel thruster.
The tunnel thruster can be equipped with
CPP or FPP and can be driven by electric
or diesel motor. The Tunnel Thruster Control
System fulfills the rules of the classification
societies and includes remote control,
safety, RPM/Pitch indication and a
back-up control system.
The Tunnel Thruster Control System is often
used in combination with a Mega-Guard
Dynamic Positioning System.
Operator Panels can be supplied for bridge
fore, bridge aft and bridge wings.
Operator panels are equipped with a pitch
and/or RPM setting lever and a control
display to select various operator modes
and to indicate pitch, RPM and motor load
or amperage. Customer can easily execute
commissioning as all parameters are
selectable on the Operator Panels in a user
friendly way.
TCS Operator Panels on bridge
Main components on each control position are:
Pitch or RPM setting lever including clutch control in case of FPP driven by diesel motor
8.4” TFT colour display equipped with pitch, RPM and load indicators.
In addition, the 8.4” TFT is equipped with 12 control pushbuttons and various other
indicators including alarms.

The Operator Panels include a built-in panel buzzer which is activated in case of alarms.
Two or more bridge panels are supplied in case of bridge fore and bridge aft or in case of
bridge wings. Bumpless take over control is realized with line-up indication lamps on the
8.4” TFT colour display or an electrical shaft (synchronization) between bridge levers can be
supplied as an option.

CPP or FPP driven by electric or diesel motor
Back-up control of pitch or RPM
The non follow up back-up control is used as a back-up in case the remote
control system fails. Typically the back-up control contains 3 pushbuttons on
each control location:
Non follow-up control; in order to select this mode
Increase pitch or RPM to starboard
Decrease pitch or RPM to portside
Alternatively: RPM setting can be equipped with a potentiometer instead of
pushbuttons. In case of FPP driven by diesel motor: back-up clutch control
pushbuttons can be integrated as well.
TCS Control Cabinet
The TCS Control Cabinet is bulkhead mounted in thruster room. The TCS Control
Cabinet includes a remote control system, an indication system (pitch, RPM,
load etc), a back-up control system and a no break power supply with power
distribution. The remote control system is built-up with a Control Processor and
two I/O Modules:
I/O Module with 18 digital inputs and 18 relay outputs
I/O Module with 4 analog outputs and up to 20 free configurable I/O points
(AI,AO,DI and DO)
Programming of TCS is in according with IEC61131 standard.
Field cables are connected to the terminal strips on the I/O Modules.
The Control Processor also supports serial interfaces which are supplied in case
the motor or drive provides a serial interface or in case a serial interface
is required with AMS (MODBUS or NMEA0183 protocol).
A no break power supply with power distribution is built-in the TCS Cabinet as well.
Two power supplies need to be connected to the Tunnel Thruster Control System:
230VAC main supply
24VDC back-up battery supply
The TCS Control Cabinet is equipped with
local indicators and pushbuttons in the front
of the cabinet:
Pitch or RPM indicator. Size: 72x72mm
Load indicator. Size: 72x72mm
Pushbutton with indication: Local Control /
Remote Control
Back-up control pushbuttons for pitch or RPM
Option: Emergency Stop pushbutton
All other components from the Tunnel Thruster
Control System are fed from the power distribution
logic in the TCS Control Cabinet. The Operator
Panels on bridge are connected to the TCS Control
Cabinet via redundant Ethernet connection.
Option: Electric motor drive
Either a soft starter cabinet will be provided
(in case of CPP) or a variable frequency drive
cabinet will be provided (in case of FPP).
Electric motors are supported from 250KW
up to 3400KW with voltages up to 690VAC.
