Precision and Reliability

The MRU 5+ provides documented roll and pitch accuracy of 0.008°

and angle noise less than 0.002°. Every unit is delivered with an

individual calibration certificate documenting this accuracy. This is

made possible by use of accurate inertial sensors including three

rate gyros and linear accelerometers of excellent tactical navigation

grade performance. Very high reliability is achieved by using solid-state

sensors with no moving parts and the proven MRU electrical and

mechanical construction.

Advanced Motion Sensing Technology

The PFreeHeave algorithm uses past measurements to output a correct

and phase-free heave from MRU 5+. It has an advantage in long swell

conditions and for applications that can utilize a heave signal that is

delayed some minutes, typical for seabed mapping applications.

Additionally, a new MEMS based gyro is developed by Kongsberg Seatex

AS called MRG5 (Mru Rate Gyro) model 5. The MRG5 is optimized for use

in high-end applications. The MRU rate gyro combines very low noise,

excellent bias stability and outstanding gain accuracy and is the best

MEMS rate gyro available for maritime applications.

Ease of Integration and Application Flexibility

Interfacing the MRU 5+ to various sonar systems is made easy by including

data protocols for the most commonly used multibeam echo sounder systems

in the software. Using the configuration cable and the Windows version of the

configuration software, MRC+, a series of simple menu prompts allow the user

to choose the optimum configuration for his application. The MRU 5+ and the

MRC+ software are flexible and can accommodate a wide variety of application

types.

The MRU 5+ product is upgraded with the best MEMS based gyro

technology available. With exceptional low angle noise and bias

stability, the product is ideal for integrated INS/GNSS systems and

demanding survey applications.

The HiPAP 352P is a portable system designed for tracking

ROVs, tow fish, divers, and other subsea objects at several

thousand metres range. Operating in SSBL mode, it measures

the distance and direction to subsea transponders and computes

a 3D position in either local or geographical coordinates.

Featuring buit -in motion sensors, the HiPAP 352P compensates

for the vessel’s roll and pitch movements, enhancingpositioning

accuracy. Models such as HiPAP 352P-H and HiPAP 352P-5

incorporate MRU-H and MRU-5 motion sensors, respectively. 

These models require no calibration for roll and pitch alignments

but do need to be calibrated in alignmentwith the vessel’s gyro compass.

Meanwhile, the HiPAP 352P-MGC combines a motion sensor and a gyro

compass,completely eliminating the need for roll, pitch, and heading

alignments calibration.

Easy to install

With the EA 600. you only need a standard data cable

between the transceiver unit(s) and the combined

display and processor. The transceiver(s) can either

be located close to the transducers, or in the vincinity

of the display. The powerful processing tasks required

does not take up any physical space any longer, as the

former Processor Unit has been fully integrated with

the LCD unit.

System software

The EA600 has a USB port in  front where a read/write

CD-ROM or DVD can be connected. Systen software

is supplied on a CD ready for installation, as are sub

sequent software releases. Data storage may also be

performed via this interface.

depth sounding profiles can easilybe retrieved at any time for

display and verification purposes.

in the EA 600 with just a click on the screen. These

functions include comprehensive context sensitive on

line  help. Save your favourite settings and call them

back when you need them.

Need multiple channels?

Up to four high-power transceivers can operate simul

taneously from the EA 600. For improved perform

ance, they are installed close to the transducers and

linked to the combined display and processor with a

single data cable. Available frequencies span from 12

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.

Features

• Scaled in technical units

• Limit check

• Alarm and monitoring for all

channels

• Trend

• Time stamp of alarms and events

(0.001 seconds)

• Built In Self Test (BIST)

• CAN net status, error handling

Main functions

• Automatic regulation of the main

engine RPM

• Automatic limiting functions such

as scavenging air and torque.

• Manual limiting functions such

as RPM and fuel limiters

• Programmed to avoid running

in barred speed range (critical

RPM)

• Automatic reduction of RPM

(slow down) function

AutoChief® Control Panel

The AutoChief® Control Panel and Engine Telegraph is

designed for easy operation and can be installed into

any standard console. An advanced, yet simple to use

touch screen computer offer easy access to all system

functions, providing the information you need only

when you need it. Main variables such as RPM, pitch,

start air and scavenging air pressure, engine state etc.

are shown. Coloring standards and dimming function

adapt the user interface to changing ambient lighting

conditions. Several levels of control are available to

distinguish between user groups.

The system can operate stand-alone, and/or integra

ted with our K-Chief automation system or K-Thrust. In

systems with shaft generators the Power Management

System can communicate with the AutoChief® system

for smooth operation. Open architecture allow seamless

integration

Bridge Wing Unit

The Bridge Wing Panel BWU21 is designed for outdoor

use with AutoChief® remote control.

The screen gives good visibility in night and daylight.

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.
