3.1 Integrated Management System
3.1.1. System Overview
Maker: Lyngso Marine
Main System Components
The machinery monitoring, alarm and control system can be divided into four groups:
DPS 2100 Main engine remote control and safety system DMS 2100 Bridge manoeuvring system
UCS 2100 Universal alarm, monitoring and control system PMS 2100 Power management system
The DPS and DMS 2100 systems are described in detail in section 2.1.2, Main Engine Manoeuvring Control.
The UCS and PMS systems are grouped by the manufacturer under the system title: ‘UMS/UCS2100 Universal Alarm, Monitoring and Control System’ The UMS system is basically the alarm system and the UCS system is the control and monitoring system.
The systems are all interconnected using an RS485 data bus, any alarms on a system group will sound common alarms according to the mode selected (UMS etc) at the designated control position.
UMS 2100 System Overview
The system is formed by a number of standard hardware units as shown in Illustration 3.1.1a.
Outstations with Local Operator Panels Basic Alarm Panels
Accommodation Alarm Panels Extended Alarm Display Alarm / Log printer
The outstation is equipped with a Gamma computer which handles the functions of the alarm detection, and additionally one of the outstations controls the alarm panels (Basic Alarm Panels and Accommodation Alarm Panels). The outstation is supplied with Local Operator Panels, which provide the operator with alarm information directly on the front of the outstation. The basic alarm panel is normally installed on the bridge and in the engine control room. It provides the operator with all the necessary facilities for use of the alarm system including alarm acknowledge, duty engineer selection, control of printer etc.
The Accommodation Alarm Panel is normally installed in the cabins of the duty engineers/officers and in the public rooms. The accommodation alarm panel is used for alarm signaling and duty call of crew members etc. in the accommodation areas.
The Extended Alarm Display is used together with the Basic Alarm Panel to extend the amount of information to be displayed simultaneously. (In the Universal Control System UCS 2100, the function of the Extended Alarm Display is an integrated part of the Graphics Operator Station GOS).
The Alarm/Log Printers are used for printing the different logs and reports. This system contains Alarm Panels which allow remote alarm annunciation at the bridge, at the engineers cabins and in the public rooms. A printer which logs all the alarms and events is connected to the system.
As the system is selected for ‘unmanned machinery space’ it will sound an audible alarm in the cabin of the engineer who has been selected on duty, as well as in the public rooms, enabling the duty engineer to move freely between any of these locations and still be sure to receive the alarm. To acknowledge the alarm, the Duty Engineer must go to the Engine Control Room. The system contains extended alarm displays which present more information, giving the operator an improved overview.
UCS 2100 Control System
This system offers an overview of alarm, control and monitoring information. The information is presented in graphic form at the Graphic Operator Stations (GOS) See 3.1.1a for system layout and location of GOS.
The UCS 2100 Control System provides the operator with an enhanced overview and operator facilities. It has facilities for displaying logged data and can be used to generate reports based upon this data. Reports, trend, and screen pictures can be printed on request. The system controls automatic and sequential restart of pumps and fans, control of temperature controllers and power management of the diesel generators.
Integrated with the UMS 2100 Alarm System, the UCS 2100 Control System will offer the standard facility to display alarm information together with the control and monitoring information. The two systems are allocated the same Gamma computer hardware modules reducing the overall costs and minimising the use of I/O channels and cabling costs.
The System Configuration is as follows:
A Graphic Operator Station on the bridge, general office, main switchboard room, and ECR (x2).
A basic alarm panel on the bridge, main switchboard room and ECR.
An accommodation alarm panel fitted in all the engineers’ cabins and public rooms.
An alarm printer and log printer in the ECR. Two Gamma outstations in the ECR.
The controlled machinery components are operated from control pictures, all with graphic representations of the controlled machinery components.
An interactive interface with pull-down menus and clear indications of the actual state of the machinery component is used. Alarms related to the controlled machinery components are visualised just beside the graphic symbol for the machinery component. The actual state of the alarm is clearly indicated (normal/cut-out/alarm).
The Graphic Operator Stations log all commands to, and condition changes from, the machinery. It also logs the change of set-points to the temperature controllers. The events are stored in a cyclic event log containing all events occurred during the last 24 hours. The event log is readable on the screen of the Graphic Operator Stations and can be printed on request.
The Graphic Operator Stations logs all of the supervised analog values. The values are stored continuously for a period covering the previous eight hours. All changes are detected and stored. Additionally, the values are also stored as one minute mean values for a period covering the last month.
Generator and Power Management System
This is comprised of the power management system and diesel starter control system. The diesel starter control system controls the following functions:

PMS Operation Modes
The ship’s electrical power plant can be operated in several different modes: Local control
Manual control of auxiliary engine Diesel Starter with Blackout Start PMS Semi-Automatic Mode PMS Automatic Mode
Local Control
In local control there is no PMS operation at all. When the auxiliary engine local control is selected for a generator set the engine is operated locally and the main breaker is operated from the MSB. The diesel generator local control is selected by means of the local/remote blocking switch on the auxiliary engine control panel at the engine.
Manual Control
In manual control, manual start/stop of the auxiliary engine from the Graphic Operator Stations is available but closing of the main breaker is limited to an automatic blackout start situation. When the auxiliary engine is in remote control and main breaker manual control is selected for a generator set, the diesel starter can start and stop the auxiliary engine in question, but only start/stop; no synchronising or any other functions are carried out. The main breaker is manually operated from the MSB. The diesel generator manual operation is selected by means of the manual/auto selector switch for each generator on the main switchboard.
Semi-Automatic Mode
The PMS modes, which always include the Diesel Start and Blackout Start functions, can be used for either operator supervised ‘Semi-Automatic’ remote control or for unmanned full ‘Automatic’ control of the ship’s electrical power plant. The PMS is changed between the two PMS modes from the Graphic Operator Stations.
In the Semi-Automatic Mode, the PMS acts as a remote control station, where the automatic controls are those of blackout start, frequency control, load sharing, start/synchronising control and disconnection of a generator when the operator enters a start or stop order from the Graphic Operator Stations. A generator cannot be connected or disconnected by the PMS automatically. If the operator wants to stop an on-line PMS controlled diesel generator, this can be done from the Graphic Operator Stations. Stopping means unloading, switching off-line and stopping the diesel generator.
Heavy consumers will be allowed to start if enough available power is present, otherwise they will be blocked from starting.
PMS Automatic Mode
In Automatic Mode the PMS will perform the functions from the Semi- Automatic Mode extended with load dependent start/stop, start of standby diesel generator at shutdown pre-warning alarm of an on-line diesel generator, and control of heavy consumers etc.
In Automatic Mode, the PMS can connect and disconnect the generators auto- matically to and from the MSB. This may be initiated by load-dependent start/stop, or from a shutdown pre-warning. The load-dependent heavy consumer start facility may involve standby diesel generator start and acceptance or rejection of heavy consumer start request.
Frequency control and load-sharing between all on-line PMS controlled diesel generators are also part of the Automatic Mode. A diesel generator can be removed from the automatic start/stop sequence by switching it to local or manual control mode.
A diesel generator can be stopped without changing its mode, by changing the priority, so that the on-line diesel generator is given a lower priority. The PMS will then automatically start a diesel generator with higher priority and stop the one with the lower priority. In the same way, starting a stopped PMS controlled diesel generator can be done by changing its priority to a higher priority. If the PMS control mode is changed from local, manual, or semi-automatic to automatic mode, the PMS will automatically update the plant, so the diesel generators with the highest priority are on-line to the MSB.
Start of the pre-selected standby diesel generator and connection of the main breaker after blackout is handled by the PMS, independent of the actual mode.
3.1.2. Operator Stations
The Graphic Operator Station is basically a personal computer approved for marine use. The various displays feature a wide range of machinery components made up of standard function blocks. The blocks are a combination of graphical symbols and corresponding control programs and include a process interface and a man/machine interface.
Operation is by using the tracker ball device to control the position of a cursor and pointing at a symbol. The activation push button (left) will then activate a pop up menu of available commands. The right button will acknowledge and open ‘display channel’ dialogue.
They also have facilities for the display of logged data as trend curves and they can be used to generate reports. These reports, trend curves and screen pictures can be printed on request.
Besides operation and graphics indication of the UCS 2100 Control System, the Graphic Operator Stations have the facility to display information such as lists for alarms, cut-outs, analog values, and alarm limits.
Alarm System
Alarms relative to the controlled machinery are displayed on the correspond- ing pictures with an indication of the alarm state and the cut-out state. A steady red square indicates an acknowledged alarm, a flashing red square indicates an unacknowledged alarm and a light blue square indicates a cut-out. By pointing and clicking on the square the actual process state can be read. When an alarm occurs, the label for the relevant system flashes on the overview display In the alarm list, the overview of all the present machinery alarms, cut outs and system failures can be seen.
Operation from the Graphic Operator Stations
To operate a machinery component the operator activates the symbol of that specific component by pointing and clicking. The desired command is chosen from the pop up menu. from the diagrams on illustration 3.1.2a the operation of starting a fuel pump (fuel pump No.1) can be seen.
a) From the overview menu the operator selects FUEL OIL SUPPLY by pointing and clicking.
b) From the fuel oil supply display the operator can assess the current status of pump No.1. The symbol is green for running, magenta for stopped, red for blocked or ‘I’ for interlocked. The alarm status square is also situated here.
c) By clicking on the symbol, the pump I.D. and command options are displayed.
d) By clicking on MASTER START, the pump is started. (For safety reasons only one GOS can operate on one symbol).
e) The pop up menu disappears and the symbol on the display changes to RUNNING.
Alarm Handling from Graphic Operator Stations
Acknowledgment of alarms is carried out at the alarm watch station and must be preceded by silencing the alarm horn by pressing the STOP HORN function key on the keyboard. The oldest unacknowledged alarm is always on display in the header. Acknowledgment is by pressing the ACKNOWLEDGE function key. Alarms from the alarm list can be acknowledged by pointing and clicking using the tracker ball.
Acknowledgment of alarms can also be made from within the corresponding control picture where the alarm indication is displayed by pointing to the flashing red symbol and clicking.

icon.Reports and Data Collection Logging
Daily, monthly and yearly reports are available as standard based on compressed data from the log. To generate a daily report the data is compressed further to provide values for each hour. Detailed reports show the 60 values for each hour plus the total values for a day. Reports can be printed out on request or at specified times. Other reports may be user configured. Data may also be exported in DIF file format for analysis using other PC applications.
Analogue and binary parameters may be logged on the GOS hard drive for later analysis. All condition changes of parameters and values, defined to be logged, covering the previous 24 hours, are stored for 30 days.
Event Log
Main Events such as running feedback signals from motors and engines can be automatically logged on the alarm and event log printer, to give the operator a complete machinery log. All events, such as commands and feedback changes, may also be logged on the Graphic Operator Stations hard-disk. The log is accessible on the Graphic Operator Stations and may be printed on a printer, either on request as a report or continuously.
The commands are only included in the log on the specific Graphic Operator Stations from which the command is actually activated.
Printers and Screen Dumps
Two printers can be connected to each Graphic Operator Station: One Graphics Printer in colour or black and white for:
Hard copy of the total screen including all windows Hard copy of the active window of the screen Hard copy of trend curves
One Text Printer in black and white for: Daily, monthly and yearly reports Trend values in tabulating form Status print-outs for a picture/system (System documentation)
Event log
The Alarms and Main Events are printed on the text printer directly connected to a Gamma computer, which is related to the UMS 2100 alarm handling function of the system.
The Thermometer (relative measuring system)
The thermometer function is a relative measurement system for supervision of, for example, the exhaust gas temperatures of the main engine cylinders with individual alarms for high temperature, high mean value and an alarm for large deviations from the mean value. The display presentation includes an overview diagram for all of the cylinders and two graph-diagrams each presenting up to five cylinder temperatures.
The thermometer picture can be selected either by the key-board function key or from the Diagrams menu.
3.1.3. Screen Displays
The display of the Graphic Operator Stations is divided into two parts: a header window and a selectable working area window which will be a control overview or an alarm list. The menu bar and header with status information are always present. For enhanced safety the header constantly displays the most essential information from the alarm system, independent of the actual control assignment, such as:
Oldest unacknowledged alarm
Number of present and unacknowledged alarms Number of present cut-outs (inhibited alarm channels) Actual watch station, duty officer and backup officer Date and time
