  customised for each system delivery.

  The intention with this manual is to explain the functionality
  for each mayor component and the total system as its configured for
  each delivery.

  How to operate the system is described in a manner where we
  assume that the system is in operation and that normal operations
  shall be carried out. This manual is not made for advanced
  troubleshooting.

  The manual contains five chapters

  2.1 Remote Control System Functional Description

  The Kongsberg Maritime C20 Marine Automation system consists of,
  among others the AutoChief C20 Propulsion Control System. Modular
  design allows flexibility in configuring the system to individual
  requirements, covering the whole range from standard propulsion
  configurations to highly advanced twin or quadruple engine
  installations with high, medium or low speed engines connected to
  reduction, reversing gear or variable pitch propellers. This system
  may be a part of a total integrated ship control system consisting
  of other sub. Systems such as:

  Alarm and monitoring system. Auxiliary control system. Power
  management system. Ballast automation system. HVAC (air
  conditioning). Management support The system is based on Kongsberg
  Maritime unified automation concept, where each individual ship
  configuration is built up using standard modules communicating on
  CAN- and local area networks. The C20 system is configurable for
  all ship types. The AutoChief C20 Propulsion Control System is
  designed for remote control of the main engine from the combined
  telegraph and manoeuvring lever in the wheelhouse. By moving this
  lever, the system will control the controllable pitch propeller and
  provide forward or reverse thrust as requested

  The ACP LCD display is used for the mayor interface between the
  operator and the system to be monitored. All interaction such as
  monitoring of propeller pitch, main engines RPM and load,
  adjustment of operational parameters and displaying of safety
  related and conventional alarms are carried out with the aids of
  this display.

  The information is selected from menus via soft-keys. When a
  menu is chosen a corresponding mimic picture will appear.

  The mimic pictures may consist of textual information, analogue
  indicators, bar graphs or soft-keys making the operator able to
  navigate into other related mimics.

  However, functions which require direct access, such as,
  emergency stop, cancel functions and alarm acknowledge / sound off
  is accessible via push-buttons on the front of the ACP.

  2.11 Remote control system functions

  2.11.1 Start fail/block As long as any of the below mentioned
  conditions is active the engine is inhibited for starting.

  2.11.1.1 Start failed Starting failure is announced from the MAN
  B&W ECS when one of the following conditions occurs, and is
  indicated on ECR and Bridge ACP.

  3 failed starts Slow turning failure

  2.11.1.2 Start air pressure low

  To secure a safe starting of the main engine a minimum starting
  air pressure is required. The value for minimum starting air
  pressure allowed is preset in parameters in the remote control
  system. If the pressure is below this preset level Start Block is
  activated.

  2.11.1.3 Engine tripped

  Engine has tripped because of a shut down detected and created
  by the safety system.

  Details to be found in the alarm list on the Safety system mimic
  pages.

  2.11.1.4 Start blocked

  If one or more of the following conditions are present the ECS
  will block the start:

  Shut down Main starting valve blocked Starting air distribution
  system blocked Control air vented Turning gear engaged Starting air
  pressure low and bridge control active Auxiliary blowers not
  operational and bridge control active

• Instruction manual AutoChief C20

  34 AA-00391-A

  When the start is blocked the ECS will release an alarm and
  route Start Blocked signal to the RCS via the serial connection.
  The ECS will automatically reset the start blocking when the
  condition has returned to normal and stop command is released.

  2.11.1.5 Engine blocked

  This is a signal from the Electronic Control System to the
  remote control system via serial line informing that the engine is
  blocked for operation. Its active if one or all of the following
  conditions is active:

  Main starting valve blocked Starting air distribution system
  blocked Control air vented

  2.11.2 Engine/CPP Not ready

  2.11.2.1 Start air distributor blocked

  For safety reasons, when the main engine is not in use, the
  start air distributor is blocked. To be able to start the engine
  the start air distributor has to be unblocked.

  2.11.2.2 Main Start air valve blocked

  For safety reasons, when the main engine is not in use, the main
  start air valve is mechanically blocked. To be able to start the
  engine the main start air valve has to be unblocked.

  2.11.2.3 Turning gear engaged

  The turning gear is mechanically engaged to the flywheel. The
  main engine is therefore inhibited from starting.

  2.11.2.4 Control air vented

  The control air valve is closed and the line is pressure
  released with a ventilation valve.

• Instruction manual AutoChief C20

  AA-00391-A 35

  2.11.2.5 Engine not ready/ready

  Engine Not Ready is used for an indication at the bridge, ECR
  and LOP. The purpose of the Engine Not Ready indication is to
  inform the navigator/engine staff that the engine is not fully
  capable of functioning. For example it may not be possible to start
  the engine again if it has been stopped.

  It is allowed to perform a start attempt if the Engine Not Ready
  indication is on. However, the normal procedure is to wait until
  Engine Not Ready deactivates before a start attempt is carried out
  e.g. after black-out.

  The ECS will route Engine Not Ready to the remote control system
  via serial connection. The Engine Not Ready signal is set active if
  the condition for engine ready is not fulfilled Engine Not Ready is
  thus the inverse of the following signals:

  Main starting valve in service position Starting air
  distribution system in service position Turning gear disengaged
  Control air pressure OK Hydraulic supply system OK Auxiliary
  blowers operational ECS OK

  2.11.2.6 CPP Hydraulic Pressure

  This function monitors the actual control oil pressure for the
  controllable pitch propeller. If the CPP pumps is not running (At
  least one) or the pressure is to low this message will appear. It
  means that we have no control of the propeller pith and therefore
  the CPP is not ready.

  2.11.2.7 CPP Not Zero

  Prior to start of the engine the propellers pitch has to be
  neutral (Zero), meaning that no ahead or astern thrust is
  initiated. If the CPP is not in zero CPP is not ready an engine
  cannot be started.

• Instruction manual AutoChief C20

  36 AA-00391-A

  2.11.3 Starting the main engine The engine is started
  automatically in ahead (or astern) direction from bridge (if the
  engine is prepared for start), simply by setting the bridge handle
  from stop to any position in ahead (or astern) direction.

  2.11.3.1 Delayed start

  This function indicates that the Prepare Start sequence has to
  be activated before the engine is Ready for start.

  2.11.3.2 Prepare Start.

  This function is activated from the ACP mimic pages, its
  activated for starting the auxiliary blowers prior to the normal
  start of the engine. As long as this sequence is not performed the
  engine will be in the state Delayed Start. When the sequence is
  ready the engine state will be Ready for Start.

  2.11.3.3 Starting Starting of the main engine is performed by
  selecting the picture ME/CPP main on the ACP. On this picture is
  possible to select a soft-key named ME Start. When the engine is
  ready for start the start signal will be sent to the MAN B&W
  electronic control system.

  2.11.3.4 Repeated start If the engine fails to start (run on
  fuel) after the starting air is switched off, the system will
  automatically try to restart the engine. Indication for «repeated
  starts» will show on bridge and ECR. If the second start also
  fails, the system will try once more. After 3 starting attempts,
  start failed alarm will be activated.

  2.11.3.5 Running The signal Running is transferred to the RCS
  from the ECS when the engine is running on fuel.

• Instruction manual AutoChief C20

  AA-00391-A 37

  2.11.4 RPM limiters For protecting the engine against thermal
  stress and destruction some fixed RPM Limiters are included in the
  ECS.

  2.11.4.1 Load Limitation

  This function is including the operational limiters:

  Chief rpm limit Torque Limiter Scavenging air Limiter

  The limiter functions is adjustable only in the MAN B&W
  ECS.

  2.11.5 QPT, Quick pass through barred speed range function

  The QPT function is an optional feature to help the main engine
  passing through the critical RPM range. In some cases its difficult
  to pull the engine through the critical RPM range as the fuel
  limiters may activate and restricting the engine to increase in
  speed. This problem is avoided as the RPM control system detects
  the critical RPM lower level and sends a zero pitch signal to the
  AC-C20 pitch control system. The AC-C20 will then take the pitch to
  zero and the speed control system will be able to increase the
  pump-index with the effect that the engines RPM will increase and
  reach the critical RPM upper level. When this RPM is reached the
  zero pitch signal is turned of and the AC-C20 take the propellers
  pitch angle up to the level which is matching the manoeuvre lever
  position.

• Instruction manual AutoChief C20

  38 AA-00391-A

  2.11.5.1 Load reduction A slow down is caused by a input signal
  detected by the slow down module. If such a signal is detected, the
  safety system will send a load reduction request to the pitch
  control system. The pitch set-point will after a pre-warning time
  be reduced to the predefined load reduction level.

  2.11.6.2 Economy mode

  This mode is selectable from the ACP mimic. Economy mode is a
  special feature controlled by the MAN B&W Electronic Control
  System. It secures the operation of the main engine with the lowest
  consumption and thereby in the most economic way.

  2.11.6.3 Fixed RPM mode 1

  This mode will be selected automatically after SEPARATE RPM or
  as default after power up. Fixed RPM mode means pitch control from
  bridge, bridge-wing or control room by the AutoChief C20 control
  levers with a fixed engine speed. Fixed RPM 1 mode can be manually
  selected by operating the ACPs mimic mode select section on the
  bridge or in control room (the one in control). The RPM level for
  this mode is adjustable but is normally set to 85% of MCR. Fixed
  RPM can not be selected if the remote control system is not in
  charge of RPM control. (which means that the ACC20system have lost
  control of the engine speed (separate RPM), in such a case, the RPM
  must be set manually to the fixed RPM position by use of the manual
  lever.

  2.11.6.4 Fixed RPM Mode 2

  Fixed RPM mode 2 is selected manually but the functionality is
  the same as for Fixed RPM 1. The fixed RPM 2 rpm level is normally
  set to 100% of MCR but is adjustable from the engine control room
  panel. In the case were the ship has a dynamic positioning control
  system the operation mode in DP-mode is Fixed RPM mode. In this
  case the dynamic positioning system gets information whether Fixed
  Rpm mode 1 or 2 is selected.

  40 AA-00391-A

  2.11.6.5 Separate RPM mode

  Separate RPM mode means pitch control from bridge, bridge-wing
  or the control room by the AutoChief C20 control levers (Local
  control of the CPP is also possible in this mode). RPM are in this
  mode controlled separately, from the speed-setting lever provided
  in the control room or from the control lever provided on the local
  engine side control station. The system will go automatically into
  separate RPM mode if the pneumatic /electric change over
  valve/switch located in the control room (and in the engine side
  control console) are set out of remote (which means that the ACC20
  system have lost control of the engine speed). An alarm Separate
  RPM mode will be announced on bridge and in control room.

  2.11.6.6 Combinator mode

  Combinatory mode means combined control of RPM and pitch from
  bridge, bridge-wing or control room by the AutoChief C20 control
  levers according to a pre-programmed combinatory curves. Combinator
  mode can be manually selected by operating the ACPs mimic mode
  select section on the bridge or in control room (the one in
  control).Combinatory mode can not be selected if the pneumatic
  /electric change over valve/switch is set to manual which means
  that the ACC20 system have lost control of the engine speed
  (separate RPM)). Combinator mode is blocked if DP-panel is in
  control.

  shut down (stop), if any of the shut down sensors is activated. The
  emergency stop solenoid valve will be activated, and the fuel rack
  to zero order is given to the governor. The engine will then stop.
  The following inputs for shut down sensors are provided: Shut down
  1: (Fixed as over speed) Shut down 2-6: (To be project specified
  for the actual

  project) Custom Shut down 1-5 (To be project specified for the
  actual

  project) The input sensors may be of digital (on/off) or
  analogue type. The shut downs may be configured as cancellable or
  non cancellable type. Non cancellable types will stop the engine
  immediately. Shut down is reset (after the sensor is de-activated)
  by setting the manoeuvring lever at the control stand in control to
  stop position. The engine may then be restarted.

  2.12.1.2 Cancellable Shut Down It will be possible, during the
  time delay, to cancel the shut down by pressing the «Cancel SHD»
  pushbutton on the ACP unit. There will be time delay on the
  cancellable shut downs. The delay time may be adjusted individually
  for each sensor. The cancellable shut-downs may be cancelled
  individually from the ACP in control room, regardless of control
  position, it will additionally be possible to cancel all shut-downs
  from bridge while in bridge control, control room in control room
  control and from engine side while in emergency control. The

  may be activated from all control stands at all time, regardless of
  the control position. Emergency stop is simply deactivated when the
  pushbutton are pressed once more.

  2.12.1.4 Over-speed Shut Down Over speed is detected by the RPM
  detection system, from tacho pick-ups which are mounted towards
  engine fly-wheel, when the engine revolution exceeds the over speed
  level (107% of MCR, adjustable). A hardwired signal from the RPM
  detection system is connected to a shut down input on the ESU for
  direct activation of emergency stop solenoid valve. And the RPM
  detection system will by dual redundant CAN order shut down of
  engine to RCS, Safety System and Governor System. This will cause
  the emergency stop solenoid valve to be activated and the fuel rack
  position moved to zero. The engine will stop and the alarm «over
  speed» will be shown on the ACP. Over speed is reset by setting the
  manoeuvring lever at the control stand to stop position. The engine

  measurement systems. These systems will at all time ensure correct
  reading of the RPM pickups and give alarm in case of
  irregularities.

  There is a hardwired connection for activating overspeed shut
  down from the RPME to the ESU (Safety system). The RPM detector
  system is used to detect over speed, critical RPM, wrong rotation
  as well as driving a variety of RPM indicators located on bridge,
  in control room and engine side.

  2.13.2 RPM detector failure RPM monitoring is critical for
  starting and running of the engine, So if the RPM measuring system

Kongsberg Maritime is delighted to announce Factory Acceptance Test (FAT) number 3000 for its highly regarded propulsion control system, AutoChief C20. The FAT took place March 8th 2011 at Kongsberg Maritime Korea’s facility in Busan, South Korea, with representatives from Hyundai Heavy Industries (HHI) and a Lloyd’s Register surveyor present.

Following the successful FAT, the system will be delivered to Hyundai Heavy Industry Engine Maker Division, for use on a large 2-stroke engine aboard HHI new building no. H2180, for shipowner Seaspan. HHI has been an important part of the AutoChief C20 story, having been the first customer to shop test the system, on a MAN B&W 6S70ME engine for a Sovcomflot vessel in November 2004.

«For the seven years following its launch in 2004, we have produced and delivered 3000 AutoChief C20 systems, which is two times faster than the previous AutoChief generation,» comments Aage Foerrisdal, Vice President Propulsion Control & Power Management, Kongsberg Maritime. «AutoChief C20 number 3000 is a fantastic milestone to reach and we’re positive that this market leading automation system has plenty of deliveries yet to come.»

AutoChief C20 is the fifth generation of Kongsberg Maritime’s propulsion control system which was originally launched in 1967. Since then, the system has undergone several major redevelopments in order to support the advances made by engine manufacturers and automation technology.

AutoChief family timeline:

1967-1988 AutoChief I and II
 — Automatic control of the engine from bridge
 — Based on TTL logic, relay logic and analogue circuits
 — Installed on 335 vessels (54 AC I and 281 AC II)

1979-1994 AutoChief III
 — Complete system with safety system & governor
 — Based on C-Mos logic and analogue circuits
 — Installed onboard 359 vessels

1991- 2006 AutoChief 4 and 7
 — Modular architecture for various applications
 — Microprocessor based propulsion control
 — Delivered to 2987 vessels

2004- AutoChief C20
 — Modular architecture for various applications
 — Micro-controller based
 — First RCS with screen based HMI
 — Fully distributed I/O and SW
 — 3000 projects delivered

The AutoChief C20 system is designed for low to medium speed diesel engines with fixed or controllable pitch propellers. Reliable, straightforward operation and quality of engineering makes the AutoChief C20 an ideal control solution for all the major engine manufacturers. Its striking exterior design also serves the purpose of simplifying operation, making it a popular choice with crew and engineers also.
