Description

The DGU is a diesel engine speed

controller. It is used on the ship’s

main engine to control the engine

RPM.

The desired engine set-point speed is

provided by either the AC600 ACP

or by a manual control lever. Once

the set point is established, the DGU

maintains the engine RPM at all

times.

The DGU includes all essential

signals related to the main governor

functions. It works as an independent

unit and will operate even if both

CAN networks should fail.

The DGU contains four CAN-buses

and two RS485 serial lines. Each port

is galvanically isolated.

The input supply voltage of 24 VDC

should not be below +18 V or above

+32 V. It is galvanically isolated.

Emergency telegraph

Process controller and IO

AutoChief®use processing controllers and IO modules

specifically designed for maritime use. These are installed

on the engine og in the Engine Control Room (ECR).

All  signals  to  and  from  the  units are  transmitted on dual

redundant CAN lines.

All nonessential sensors can be shared with the  K-Chief

alarm  and  monitoring system,  requiring  only  one

interface  to  the main engine. This principle drastically

reduces the installation and cabling cost.

Main features:

• Redundant field bus (CAN)

• Signal interfacing to sensors and actuators

• Alarm detection and process control

• Time stamping of alarms and events

Operator stations

The Operator Stations are used to receive alarms and to

allow monitoring and control of the system. They display

status pages and interactive process diagrams. They also

give access to the I/O Units for inspection of variables,

operation of equipment and adjustment of parameters.

Changing limits or parameters in one Operator Station will

automatically update all other stations. All operator actions

such as the starting or stopping of pumps or changing

alarm limits, are logged and time tagged. Process views

contain easy‐to‐read information about the engine and

surrounding equipment. Control of different process plants

and machinery is done directly from any Operator Station.

Full monitoring and alarm facilities are provided in both

the machinery space and in the control rooms. All changes

in alarm and measuring points from the I/Os are logged and

time stamped.

Data are stored in all Operator Stations for 28 days. They can

be displayed in the Event and Trend history view. Extended

logging of data is included in our information management

system.

Energy Control System

The K-Chief Automation System is tightly integrated with Kongsberg’s K-Pow

er solutions for AC and DC electric grids. Direct access to generator protection

units, drives and converters ensure smooth and optimal control of the vessels

electric plant.

Common technology

The use of common technology in the Kongsberg portfolio

has allowed us to develop modular products. The benefits

of modularity are passed on to our customers through:

• Identical basic software platform in the K-Line systems

• Free flow of information between the K-Line systems

(K-Chief, K-Safe, K-Power, K-Pos, K-Thrust, K-Bridge &

K-Gauge)

• Well-proven solutions that focus on the complete vessel

operation

• Operational consistency

• Reduced spare part and training requirements

The information management system may be integrated to

K-Chief via the administrative network, allowing the user to

define trend displays and create tailored reports.

System architecture

The K-Chief system architecture has a modular design,

and builds on Operator Stations and I/O modules

interconnected by local data networks. This allows us to

meet individual ship owner’s requirements using standard

modules. Different selections of these units are used to

configure each individual system.

The K-Chief is decentralized with redundant controllers for

each segment for availability, but operation is centralized

using the Operator Stations. Each I/O module has a

specific role and is configured to match the operational

requirements of the specific process area. Due to this

flexible architecture, the K-Chief system can connect

more I/O modules in the network later on. This may be

done to control additional process areas, or to extend the

functionality. Vendor’s equipment,  such as valve control

systems, fire alarm systems and level gauging, can be

interfaced on communication lines connected directly to

the process network.

Key features

K-Chief offers cost effective standard solutions with the

possibility of tailoring to individual requirements. Modular

design allows flexibility in configuring the system, covering

Sensitivity

Kongsberg Discovery has been developing satellite based AIS

receivers since 2010 and this space-based AIS technology

has strong focus on receiver sensitivity. The high sensitivity

performance has been incorporated in the AIS BS600. The

increased sensitivity exceeds the requirements in international

standards and regulations, and is an incredible enhancement

in terms of signal reception, greatly increasing the offered base

station range.

Efficient deployment

An integrated display and keyboard enables easy configuration

of essential parameters. Detailed setup can be carried out via the

web interface.

DGNSS correction distribution

The AIS BS600 is capable of broadcasting DGNSS corrections

through the standardized AIS message type 17. Hence, differential

corrections can be transmitted to all vessels which carries an AIS

mobile station if the vessel is located within the coverage area of

the base station. The AIS BS600 also supports RTCM via serial and

LAN interface.

Remote configuration and operation

The AIS BS600 has several serial interfaces and multiple Ethernet/

LAN interfaces, making it easy to connect the base station to other

equipment or data networks. From the AIS Service Management

Application Suite a single AIS BS600. or a network of base stations,

can be remotely operated and maintained. The AIS BS600

supports configuration and firmware upgrade via a web interface.

All base station functions can be configured and effectuated via

this interface.

Hot standby

In order to obtain a very high level of service and availability, a

redundant base station configuration can be established. Two AIS

BS600 units will operate autonomously in such a configuration

without any additional hardware. In case of an automatic change

in the redundancy configuration, the control centre will be notified.
