The Mega-Guard Tunnel Thruster Control System (TCS)fully automates from bridge the control of the tunnelthruster. The tunnel thruster can be equipped with CPP orFPP and can be driven by electric or diesel motor.

The Tunnel Thruster Control System fulfills the rules of theclassification societies and includes remote control, safety,RPM/pitch indication and a back-up control system.The Tunnel Thruster Control System is often used incombination with a Mega-Guard Dynamic PositioningSystem.

Operator Panels can be supplied for bridge fore, bridgeaft and bridge wings. Operator panels are equipped witha pitch and/or RPM setting lever and a control display toselect various operator modes and to indicate pitch,RPM and motor load or amperage.

Customer can easily execute commissioning as allparameters are selectable on the Operator Panels in auser friendly way.

Features

Main components on each control position are:

TCS Operator Panels on bridge

Pitch or RPM setting lever including clutch control in case of FPP driven by diesel motor5.7” TFT colour display equipped with pitch, RPM and load indicators.In addition, the 5.7” TFT is equipped with 6 control pushbuttons and various otherindicators including alarms.Back-up control of pitch or RPM and clutch in case of FPP driven by diesel motorOption: Emergency Stop pushbutton

Two or more bridge panels are supplied in case of bridge fore and bridge aft or in caseof bridge wings. Bumpless take over control is realized with line-up indication lamps onthe 5.7” TFT colour display or an electrical shaft (synchronization) between bridge leverscan be supplied as an option.

TCS Operator Panel control functions

Pushbuttons are integrated on the Operator Panel with function indication on the5.7" TFT colour display. The following typical functions can be selected:

Start motor and stop motor DP/Joystick modeLoad trim setting (%)Emergency mode selectionTake over control from bridge fore to bridge aft and/or to bridge wings and vice versaDimming mode selection Parameter mode selection

Option: Electric motor drive

Either a soft starter cabinet will be provided(in case of CPP) or a variable frequency drivecabinet will be provided (in case of FPP).Electric motors are supported from 250KWup to 3400KW with voltages up to 690VAC.

Back-up control of pitch or RPM

The non follow up back-up control is used as a back-up in case the remotecontrol system fails. Typically the back-up control contains 3 pushbuttons oneach control location:

Non follow-up control; in order to select this modeIncrease pitch to starboardDecrease pitch to portside

Alternatively: RPM setting can be equipped with a potentiometer insteadof pushbuttons. In case of FPP driven by diesel motor: back-up clutchcontrol 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 indicationsystem (pitch, RPM, load etc), a back-up control system and a no breakpower supply with power distribution. The remote control system is built-upwith a Control Processor and two I/O Modules:

230VAC main supply 24VDC back-up battery supply

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 casethe motor or drive provides a serial interface or in case a serial interfaceis required with AMS. Two power supplies need to be connected to theTunnel Thruster Control System:

I/O Module with 18 digital inputs and 18 relay outputsI/O Module with 4 analog outputs and up to 20 free configurableI/O points (AI,AO,DI and DO)

The TCS Control Cabinet is equipped withlocal indicators and pushbuttons in the frontof the cabinet:

All other components from the Tunnel ThrusterControl System are fed from the power distributionlogic in the TCS Control Cabinet. The OperatorPanels on bridge are connected to the TCS ControlCabinet via redundant Ethernet connection.

Dual indicator for pitch and shaft RPM orload indicator implemented on 5,7" TFTBack-up control pushbuttons for pitch or RPMOption: Emergency Stop pushbutton
