1 General Overview

Operation of the machinery automation control and monitoring system (MCS) provided by Robichaux Automation and Control, Inc. (RAACI) for FRV-40 hulls 3 and 4 is described throughout this document. The MCS is a computer based system consisting of 5 workstations connected together over a redundant Ethernet network. The workstations provide the operators and crew with a man machine interface (MMI). The two workstations physically located in the engineer’s operating station (EOS) are labeled Primary and Secondary. These workstations are responsible for gathering I/O data from the data acquisition units (DAU’s) and for performing control algorithms. Only one of the two workstations is in control at any given time. The two workstations negotiate control location via heartbeats between them. The MCS includes several Data Acquisition Units (DAU’s) strategically located throughout the vessel so as to minimize cabling to field transducers. The DAU’s are networked back to the EOS using Modbus Serial communications over fiber links.

The following page illustrates the MCS system provided by RAACI. This diagram will be referenced throughout the description of operation.

Figure 1 System Diagram

2 Description of Operation

Refer to Figure 1 – System Diagram throughout description below.

2.1 Workstations

The MCS consists of five workstations –

• Main Control Console (MCC) Primary Workstation

• MCC Secondary Workstation

• Bridge Workstation

• Chief Engineer’s Workstation #1

• Chief Engineer’s Workstation #2

The MCC and bridge workstations are ABS approved 2.4 GHz Pentium IV computers with 6 PCI slots on the motherboard. Each includes 512 MB DDR Ram, a 1.44MB floppy drive, 80 GB hard drive, CD-RW 52x32x52, 6 GB flash drive, 2 Network Cards and Windows XP Professional.

In addition, the MCC workstations include two 8 port serial expansion cards. The serial cards are used to interface with the various serial equipment, including the RAACI DAU’s, the RAACI Engineer Alarm Panels/Stateroom Alarm Panels (EAP/SAP’s), and the Caterpillar Customer Control Modules (CCM’s). The MCC workstations are the only workstations on the MCS network that connect to I/O equipment and therefore they are the only workstations requiring the serial expansion cards.

The MCC and bridge workstations each include an ABS approved Innova 21” LCD. The bridge display is dimmable to complete darkness. These workstations also include panel-mount sealed keyboard and mouse.

The two chief engineer’s workstations are the latest Desktop DELL Pentium computers and include table top keyboard, mouse, and 19” LCD displays. These computers include 2 network cards, identical to those in the MCC and Bridge workstations.

All five workstations are the man machine interface (MMI) to the MCS. The workstations include graphical screens for monitoring and controlling the various MCS equipment. The MCS MMI includes a main menu page for navigating through the screens. Each screen includes a mini alarm summary window for alerting the operator to the most recent alarms. The MMI was developed by RAACI using Intouch software made by Wonderware, Inc.

The MCC, bridge and Chief Engineer’s workstations each run the MCS MMI software developed by RAACI. The MCS data represented on the MMI is retrieved from the MCC workstations over the Ethernet network. In addition, any control actions initiated on the bridge and/or Chief Engineer’s workstations is propagated over the Ethernet network to the MCC workstation in control at the time of the control action.

In addition to running the MCS MMI software, the MCC workstations also run other software. The MCC workstations run the Modbus Communication Driver for communicating with the RAACI DAU’s and RAACI EAP/SAP’s and the Cat CCM Communication Driver for communicating with the Cat Customer Communication Modules (CCM’s). Both communication drivers are modules in the Omniserver software running on the MCC workstations.

In addition, the MCC workstations also run software for communicating with the Allen Bradley Drive PLC’s. The PLC driver is called RSLinx.

Finally, the MCC workstations run the MCS control algorithms developed by RAACI with the Incontrol software by Wonderware, Inc.

The various software packages running on the MCC workstations share data via a standard open protocol interface.

At any given time either the MCC primary or MCC secondary workstation is in control of the MCS plant including polling the DAU’s and CCM’s for data or commanding control actions or running control algorithms. The primary and secondary workstations negotiate control based on heartbeats existing between the two computers. The MCS MMI software will alert the operator of which computer is in control at all times. An alarm will sound notifying the operator that a computer has taken control away from the other computer.

The five workstations are networked over a redundant 10/100Mbps Ethernet network.

The workstations automatically switch between networks in the event of a failure. Each network is monitored for status and alarmed in the event of a failure.

The Ethernet network is a 10-Base2 coaxial network. The workstations are daisy chained with a “T” connector. The two workstations at the ends of the daisy chain have 50 ohm terminators installed on the open end of the “T” connector.

The MCC primary and secondary workstations include serial expander cards. The serial expander cards connect to a RAACI printed circuit board which converts RS-232 serial communications to both RS-485 serial communications and fiber serial communications.

The RS-485 serial communications is used to communicate with RAACI remote terminal units (RTU’s) physically located in the MCC console, with the remote EAP/SAP’s and with the RAACI CCM concentrator physically located in the MCC console. The fiber serial communications is used to communicate with remote DAU’s.

2.2 Data Acquisition Units (DAU)

There are a total of 8 DAU’s strategically placed throughout the vessel for interfacing with the various MCS I/O.

• DAU 1 – Main Machinery Room Lower Level Port

• DAU 2 - Main Machinery Room Lower Level Stbd

• DAU 3 – Auxiliary Machinery Room

• DAU 4 – Transducer Room

• DAU 5 – Winch Room

• DAU 6 – Ship Service Switchboard

• DAU 7 – Main Machinery Room 2nd Deck

• DAU 8 – Emergency Generator Room

The DAU’s are located so as to minimize transducer cabling. The DAU’s are each connected in a redundant home-run fashion back to the MCC using two fiber pairs. The fiber connections within the DAU are converted to RS-485. The RS-485 redundant channels (Channel A and Channel B) are distributed throughout the DAU to each remote terminal unit. Fiber is used as the interconnect medium between the MCC and DAU’s in order to minimize EMI effects on communications. In addition, because each DAU is connected in a home-run, any type of failure will only affect the one DAU. However, since there are two separate fiber optic runs to each DAU, a single failure will not disable a DAU.

Each DAU is powered by 120Vac and includes a 24Vdc power supply, with battery backup, for powering the internal remote terminal units and I/O frames.

The DAU’s include a variety of remote terminal units and I/O frames for interfacing with different transducers including digital inputs, digital outputs, relay outputs, RTD inputs, 4-20mA inputs, and voltage inputs. The digital inputs are wired in fail safe mode – closed is normal and open is alarm. The analog inputs are calibrated prior to delivery and do not need to be re-calibrated periodically or field calibrated. Refer to the RAACI schematics for transducer hook-up information.

Several I/O frames within the DAU’s can be configured using shunt jumpers. The required jumper configuration for each application is included in the system schematics on the sheet with the applicable I/O frame.

In addition to the DAU’s, the consoles also have monitoring and control parameters as listed below:

• 2002-02S1000: Ship Control Console (Drop-ins) o Control Transfer o EOT o Throttle Lever o UPS o DPS Interface o Attendance Monitor o Aft Console Controls/Indications o Bridge Wing Consoles Controls/Indications

2.3 Engineer Alarm Panels and Stateroom Alarm Panels

There are a total of two engineer alarm panels:

• Mess Room Alarm Panel

• Lounge Alarm Panel

There are a total of three stateroom alarm panels:

• Chief Engineer Alarm Panel

• First Engineer Alarm Panel

• Second Engineer Alarm Panel

The EAP and SAP’s alert the crew to Vital Alarms, Non-Vital Alarms and also inform if the EOS is attended. The vital alarms flash in red and sound with a pulsing tone. The non-vital alarms flash in yellow and sound with a constant tone. The EOS attended/un-attended status indicates in green and has no audible tone. The Fire alarm indicates in flashing red, similar to a vital alarm, but sounds a unique warble tone.

If the EOS is attended the EAP and SAP alarms are disabled with the exception of the Fire alarm, power failure alarm, bilge alarm and assistance needed alarm which is always active at all panels. If the EOS is un-attended, both EAP’s indicate all alarms and the one stateroom alarm panel, selected for duty, indicates all alarms. In the machinery space un-attended mode, the active SAP is selected from any of the workstation MMI’s using the Duty Selector Switch.

If an alarm at the EOS remains unacknowledged for 5 minutes, then the Assistance Needed Alarm will indicate and sound at all EAP’s and SAP’s.

The alarms at the EAP’s and SAP’s are acknowledged at the MCC. The alarms can not be acknowledged from the EAP or SAP directly.

The EAP’s and SAP’s each include a Power On indicator and a System Failure indicator.

The system failure indication alerts the operator that the EAP or SAP has not had communications with the MCC for 5 consecutive seconds. Consequently, without communications with the MCC the alarm panel cannot indicate the current status of any alarms.

Each panel also includes a lamp test button, which illuminates all lamps steady, and several horn test buttons, which test the three different tones – vital, non-vital, and fire.

These buttons should be exercised periodically to ensure continued operation of the panel.

Regarding communications, all panels are connected in a daisy-chained fashion back to the MCC. The communication scheme is redundant Modbus over RS-485 serial communications. Each panel includes two serial links – channel A and channel B, identical to that provided in the DAU’s.

The panels are powered with 24Vdc derived at the MCC.

The stateroom alarm panels include dimmer buttons for setting the illumination intensity of the indicators. The intensity setting is for indications that are on steady. Flashing indicators (new alarms) always indicate at maximum brightness.

In addition, the stateroom alarm panels include a watch call feature. The operator in the EOS can use the MMI to call either the chief engineer, first engineer, or second engineer.

The operator selects the desired engineer and the EAP watch call indicator will illuminate in green and the non-vital horn will sound. The engineer can acknowledge the watch call at the EAP by pressing the Watch Call Ack pushbutton.

2.4 Serial Networks

The MCS uses the Channel A serial network for normal communications. The MCS will periodically send a status message across the Channel B serial network to test the integrity of Channel B, the backup serial channel. The MCS will alarm on the MMI a failure of either serial channels.

In the event of a communication failure on Channel A, the MCS will automatically switch communications over to channel B. The operator will receive an alarm describing the failure of the communications Channel.

The operator should correct the problem on Channel A and then use the MCS MMI to switch communications back over to Channel A, the primary communications channel.

The switchback is not automatic.

2.5 Main Control Console

The Main Control Console (MCC) is located in the EOS. The MCC includes two workstations – the primary workstation on the left side of the console and the secondary workstation on the right side of the console. The workstations provide the man machine interface to the MCS. In addition, the following controls and indications are included on the MCC:

2.5.1 Console Operations

The Console Operations section of the MCC includes pushbuttons for periodically testing the horn and lamps. The horn test pushbutton will audibly sound the horn in a constant tone. The lamp test pushbutton will illuminate all console indicators. The operator should periodically use the test buttons to confirm the functionality of the horn and that all indicators illuminate properly.

The Console Operations section also includes an Acknowledge pushbutton. The acknowledge pushbutton can be used to acknowledge alarms on the MCS MMI. The MCS MMI also includes a soft pushbutton on each screen for acknowledging alarms.

2.5.2 Attendance Monitor

The Attendance Monitor section of the MCC is used to indicate the status of the EOS – attended or un-attended. The operator should put the Attendance Monitor in the Attended mode while manning the EOS and/or machinery room. The operator sets attended mode by pressing the Attended Illuminated Push Button (IPB). The Attended IPB should illuminate steady and the Un-Attended IPB should be extinguished. Likewise, the operator sets the unattended mode by pressing the Un-Attended IPB. Then the Un- Attended IPB should illuminate steady and the Attended IPB should be extinguished.

While in attended mode, the operator is required to periodically “check-in” by pressing the Engineer Report IPB every 30 minutes. If the operator has not pressed the Engineer Report IPB within the past 25 minutes, the Engineer Report IPB will flash and the non-vital horn will sound. If the operator has not pressed the Engineer Report IPB within the past 30 minutes, an additional 5 minutes from the time that the Engineer Report IPB began flashing, the Failed To Report indicator will flash and the horn will continue to sound. In the event of a Failed To Report condition, the assistance needed horns will also sound and the assistance needed indicators on the EAP/SAP’s will alarm.

2.5.3 Station In Control

The Station in Control section of the MCC is used to transfer control of the motors between the bridge, MCC, and local stations. In addition, the station in control section includes a Throttles Aligned indicator for bumpless transfer. During a transfer, the throttles aligned indicator will illuminate if the command between the two stations is within 5 %. For all cases the throttles must be aligned in order to successfully complete a station in control transfer. The only transfer not requiring the throttles to be aligned is when a lower station takes control from a higher station, for example, if the MCC takes control from the SCC as discussed below.

The station in control will always be illuminated steady. During a transfer, the EOT bell will sound and the transferring station will flash. Transfers occur as follows:

• LOS to MCC LOS must give control to MCC at the local panel. When control is switched to the MCC, the MCC IPB will indicate steady (indicating the active control station), the LOS IPB will flash, and the EOT bell will sound. The operator at the MCC acknowledges the control transfer by pressing the flashing LOS IPB. The LOS IPB will then extinguish and the EOT bell will be silenced.

• MCC to LOS LOS can take control from MCC at the local panel. When control is switched to the LOS, the LOS IPB will indicate steady (indicating the active control station), the MCC IPB will flash, and the EOT bell will sound. The operator at the MCC acknowledges that the LOS has taken control by pressing the flashing MCC IPB. The MCC IPB will then extinguish and the EOT bell will be silenced.

• MCC to SCC

Option1: While in MCC control – the MCC indicator is illuminated steadily and the LOS and SCC indicators are extinguished, the SCC may request control from the MCC by pressing the SCC IPB at the SCC. The SCC IPB will begin to flash and the EOT bell will sound at both the SCC and the MCC Consoles. The MCC IPB will remain illuminated steadily (indicating the controlling station.)

The SCC can cancel the request by pressing the MCC IPB. The MCC gives control to the SCC by pressing the flashing SCC IPB at the MCC Console. Control will be is switched to the SCC if the MCC and SCC throttle levers are sufficiently aligned. When transfer to the SCC occurs, the SCC IPB will indicate steady (indicating the active control station), the MCC IPB will extinguish, and the EOT bell will silence.

Option 2: The MCC may request control be transferred from the MCC to the SCC by pressing the SCC IPB at the MCC. The SCC IPB will begin to flash and the EOT bell will sound at both the SCC and the MCC Consoles. The MCC IPB will remain illuminated steadily (indicating the controlling station.) The MCC can cancel the request by pressing the MCC IPB at the MCC Console. The SCC completes the transfer and takes control by matching its throttle lever with the throttle lever in the MCC and then pressing the flashing SCC IPB at the SCC Console. When control is switched to the SCC, the SCC IPB will indicate steady (indicating the active control station), the MCC IPB will extinguish, and the EOT bell will silence.

• SCC to MCC

Option1: While in SCC control – the SCC indicator is illuminated steadily and the LOS and MCC indicators are extinguished, the MCC may take control from the SCC by pressing the MCC IPB at the MCC. The SCC IPB will begin to flash and the EOT bell will sound at both the SCC and the MCC Consoles. The MCC IPB will illuminate steadily (indicating the new controlling station.) This transfer will occur regardless of throttle positions. The MCC nor the SCC can cancel the action of taking control. The SCC acknowledges the transfer of control by pressing the flashing SCC IPB at the SCC Console. The SCC IPB will extinguish, and the EOT bell will silence.

Option 2: The SCC may request control be transferred from the SCC to the MCC by pressing the MCC IPB at the SCC. The MCC IPB will begin to flash and the EOT bell will sound at both the SCC and the MCC Consoles. The SCC IPB will remain illuminated steadily (indicating the controlling station.) The SCC can cancel the request by pressing the SCC IPB at the SCC Console. The MCC completes the transfer and takes control by aligning its throttle lever with the SCC throttle lever and then pressing the flashing MCC IPB at the MCC Console. When control is switched to the MCC, the MCC IPB will indicate steady (indicating the active control station), the SCC IPB will extinguish, and the EOT bell will silence.

• LOS to SCC

Cannot directly transfer from LOS to SCC.

• SCC requests from LOS Cannot directly transfer from LOS to SCC.

2.5.4 Throttle Level and EOT

Also included on the MCC console are the throttle lever and engine order telegraph (EOT). The throttle lever controls the speed of the on-line motors – forward and reverse.

Distributed amongst the throttle lever scale are EOT positions. The EOT positions are illuminated when the MCC has control of the throttles. As the throttle is moved to a new command, the corresponding EOT position is indicated as a flashing indicator. The position of the MCC throttle lever is indicated on the EOT as a steady indicator. When the SCC and MCC throttles are in the same EOT position, the indicator illuminates steadily.

When in MCC control, if the MCC and SCC throttles are at different EOT commands, then the MCC EOT position is illuminated steady, the SCC EOT position is illuminated flashing, and the EOT bell sounds audibly, and the EOT Standard Order Mismatch indicator illuminates flashing.

When at the Stop EOT position, the operator can select the Standby mode or the Finished with Motors mode by pressing the corresponding IPB. The indicator will then illuminate steady. The MCC must match that command in order to silence the EOT bell by pressing the same indicator at the MCC.

When in SCC control, the EOT indicators are extinguished.

2.5.5 Emergency Shutdowns

The MCC console includes several emergency shutdown mushroom knobs.

• Motor 1

• Motor 2

• Engine Room Ventilation

• Ship Ventilation

• Fuel Oil System

• Generator #1

• Generator #2

• Generator #3

• Generator #4

The knobs are normally extinguished and in the pushed down position. The operator activates the shutdown by lifting the mushroom knob. When lifted the knob illuminates steady.

2.5.6 Assistance Needed

The MCC console includes an Assistance Needed mushroom knob. The knob is normally extinguished and in the pushed down position. The operator activates the Assistance Needed alarm by lifting the mushroom knob. When lifted the knob illuminates steady. The assistance needed knob activates the assistance needed and the assistance needed alarms at the EAP and SAP’s. The assistance needed mushroom knob is monitored by the MCS and will alarm on all workstations in the event that it is activated.

2.5.7 Pump and Valve Controls

The MCC console includes several pump and valve controls.

• Independent Bilge Pump Valve – Open Command, Closed Command

• Bilge Pump – Fast Command, Slow Command, Stop Command

• Fire Pump – Start Command, Stop Command

• EGG Sampling Pump – Start Command, Stop Command, Run Indication

• SCI Seawater Pump #1 – Start Command, Stop Command, Run Indication

• SCI Seawater Pump #2 – Start Command, Stop Command, Run Indication

These controls and indications are hardwired to the respective equipment.

2.5.8 Console Power

The MCC console indicates whether power is available from the normal power source or the emergency power source. These indicators are normally both illuminated. The MCC console automatically switches to the emergency power source upon loss of the normal power source.

2.5.9 Shaft RPM

The MCC console indicates the current shaft RPM on the Shaft RPM Meter. The shaft RPM meter is driven directly by a shaft RPM repeater board located in the MCC console.

The actual shaft RPM is obtained from a shaft tachometer monitored by the MCS.

2.6 Drop – In Panels at SCC, Bridge, Wings, and Aft Stations

The Drop-in panels are controls and indications that are similar to those explained in the MCC Console section above. In addition, the drop-in panels include a dimmer knob for controlling the intensity of the panel indications. The drop-in panels also include additional control station options for transferring throttle control. When the SCC is the station in control, then control can be transferred to either bridge wing, the aft station or the DPS system. Control is transferred to the DPS by pressing the DPS IPB. Control is transferred to either bridge wing or the aft station by pressing the desired location’s IPB.

The desired locations’s IPB will flash at all locations and the SCC IPB will remain illuminated steady and the EOT bell will sound. The transfer is completed by the new station moving its throttle lever until the Throttle Aligned Indicator illuminates, indicating that the new station’s throttle lever is aligned with that of the SCC. The SCC then presses the desired locations IPB. The new station IPB then illuminates steady and the SCC IPB extinguishes and the EOT bell silences. The throttles must be aligned for a successful transfer.

2.7 Tank Level Indicators

The RAACI MCS includes two tank level indication panels.

• Fuel Tank Level Indication Panel

• Ballast Tank Level Indication Panel

The RAACI MCS monitors the various tank levels through DAU’s throughout the vessel.

The tank level is then linearized in the MCC Primary and Secondary workstation’s Incontrol software. The linearized tank level values are then serially communicated to the tank level indicators for remote viewing.

2.8 Software – MMI

A number of mimics are included to reflect the actual plant and the corresponding location of monitoring points. Mimics are included in detail for each system as well as overview mimics for ease of use.

The individual alarm displays are typically gray while in a normal state. The alarm displays flash red and sound an audible horn when an alarm is active. The alarm continues to flash and sound until acknowledged by the operator. If the alarm condition persists, after it is acknowledged by the operator, the indicator displays steady in red and the horn is silenced. A normal condition returns the indicator to gray. Each new alarm reactivates the audible horn and flashes red the respective alarm window.

The Main Control Console includes a soft duty selector switch, on the MMI, which is used to select the active stateroom alarm panel when the machinery space is unmanned.

At least one stateroom alarm panel is active at all times.

All control functions available on the MMI are password protected. There are several levels of password protection with the administrator password and chief engineer password having full system access and control.

Each screen includes a mini alarm summary window in the bottom right hand corner.

The mini alarm summary window alerts the operator to the most recent 6 alarms. Those 6 alarms appear on the screen simultaneously in a tabular format. In addition, the operator has the ability to scroll, with the up and down arrows, throughout all active alarms.

Active, unacknowledged alarms appear in red. Active, acknowledged alarms appear in black. Alarms that have not been acknowledged, but have returned to their normal state appear in blue. Each alarm includes the alarm name, the time of occurrence, the operator logged in at the time of the alarm, and the setpoint value exceeded. Alarms activate independently of one another, meaning one alarm will not prevent or inhibit another from occurring. The system is not limited as to how many alarms can occur or be active simultaneously. All alarms include visual indication, as well as audible. The machinery space includes beacons and horns to alert the operator in the machinery room to an active unacknowledged alarm at the MCC.

Miscellaneous screens are included with the MCS system for trending, viewing historical logs, viewing alarm logs, system status/communication status, operator rights and logging into the system, modifying setpoints and time delays.

The various screens allow the operator to monitor all parameters coming into the MCS including pressures, temperatures, tank levels, and status indications. In addition, the screens give the operator the ability to control the various MCS equipment. Controls may include pumps, valves, generators, and motors.

2.9 Software – Control Algorithms

The MCC workstations run the MCS control algorithms developed by RAACI with the Incontrol software by Wonderware, Inc. Only one workstation is running the algorithms at any given time. Typically the primary workstation runs the algorithms while the secondary workstation monitors the primary workstation and takes over in the event of a failure. In the event of a failure the primary workstation should be repaired and restored to its normal operating state and the control functions should be switched back to the primary. The algorithms are switched back to the primary station using the MMI on the secondary workstation. The switchback is not automatic.

The control algorithms will automatically start and stop standby generators based on current vessel loads. In addition, the control algorithms will monitor the throttle position and add standby generators as required to meet the throttle command.

When in DPS control, the control algorithms will use the DPS commands as received through RTU’s to control the plant. In DPS control, the standby generators will be added and removed as necessary to support the DPS commands.

In the event that the control algorithms require more generator capacity but the operator does not have any generators setup in standby. The control algorithm will alarm and limit the throttle command so as not to overload the on-line generators.

2.10 Miscellaneous

The RAACI MCS includes two machinery space horns and beacons. Alarms at the MCS will sound the console horns as well as the machinery space horns and illuminate the machinery space beacons.
