K-Nav Radar

The radar display unit is a type-approved radar /

ARPA on which approved nautical charts can be

displayed as an underlay to the radar video.

Raw data from the antenna is processed in the display

unit, which means that filtering is applied locally

according to the operator’s requirements. The display

unit tracks its own targets and also displays AIS

targets. If radar and AIS targets duplicate each other,

they are ”associated”: the system replaces them with

a single new target (and identifier). This ensures that

the operator cannot mistake a single ship detected by

both radar and AIS for two vessels.

To enhance radar performance and avoid blind

sectors, video from up to four radars can be displayed

simultaneously in a composite radar picture. The

system automatically tracks targets across boundaries

between the sectors covered by each radar.

Technical description

4 – 20 mA

CAN/RS-485 Modbus

Power 24 VD

Low energy, high frequency radar pulses are generated by

the Signal Processing Unit (SPU) and transmitted via coaxial

cables to the Stationary Antennas installed inside each cylin

der compartment.

The antenna transmits the signal further into the open space

of the crankcase. When the sensor passes the antenna,

the radar pulse is picked up. The SAW element at the tip of

the sensor then reflects the signal which is picked up by the

stationary antenna and sent back to the processing unit for

interrogation.

The shape and characteristics of the reflected pulse deter

mine the temperature of the sensor, i.e. the bearing temper

ature. The processing unit software calculates the tempera

ture and transmits this to the engine control and monitoring

system.

The SPU uses a multiplexer to monitor up to 16 channels in

sequence. Calculation time for each channel is appr. 25 ms.

Installed on a 10 cylinder engine running at 600 rpm all 10

channels are up-dated in less than one second.

The multiplexing and low signal strength reduces noise and re

moves any danger of overhearing from one cylinder to another.

All sensors and antennas can therefore be similar. This reduces

number of variants and represents a huge benefit in terms of

keeping spares.

Mechanical design and installation

KONGSBERG US thruster family has set the industry standards for decades

being one of our all-time most selling propulsion product. US thrusters have

been the obvious choice for ship applications where reliability and performance

really matters, which is proven by thousands of vessels equipped with US

thrusters in the past. US thrusters are constantly evolving to satisfy the

customer needs with tailored solutions and services.

KEY ADVANTAGES ON USING KONGSBERG US THRUSTER

• Flexible modular design, options to choose from

• Superior thrust performance

• Future proof digital features

• Value adding services

Thrusters developed together with our customers

Towing industry is one the main market segments for US thrusters. Many

tug owners today are more and more interested in the product life cycle

costs than the lowest purchase price. Effective shipyards are searching

ways to cut both time and costs from boat building processes. The shipping

industry sets new standards for performance to be able to tow larger

vessels. We have been listening to our customers from each side and

created new features accordingly, many of them being a win-win solution

for all parties.

Purpose

• Transport chain from cable lifter

AHT winch to chain lockers at

main deck.

Principle

• The chain handling unit is self

sufficient with the exception of

main electric supply.

• The unit is designed to be mounted

on rails fixed to ship deck.

• Operation and control of the

chain handling unit is by radio

control.

Advantages

• Back tension for cable lifters.

• Increase storage capacity in

chain lockers.

• Having a chain handling unit

available, makes it possible to

install more chain lockers in

the vessel

• Main data

• Capacity:  2 x hydraulic driven

adjustable chain wheels

operating at max capacity

simultaneously.

• Skidding system: capacity to skid

both directions at full working

load. Carriage motor skidding

drive with parking brake.

Chain pull winch capacities

• Tension pulling: 2 to 10 T at 1 m dia.

• Speed pulling: 0 to 30 m/min.

at 1 m dia.

• Back tensioning: Same as

pulling, but tension or speed

must be adjusted according to

cooling capacity.

165 mm.

Carriage machinery

capacities

• Pulling capacity: 40 T at 0 to 6

m/min.

• Speed: 0 to 6 m/min.

The K-Bridge 26” Multi-functional Display combines the capabilities

of individual Radar, ECDIS and Conning stations in a single unit.

The 26” MFD is designed to be deployed in multiple locations

around the bridge. In each location it operates as a fully

standards-compliant Radar, ECDIS or Conning system; and at

any time its role can be instantly switched.

This gives the bridge crew maximum flexibility to adapt the

navigation operator stations to their immediate operating

requirements.

The facility for instantly shifting command of the autopilot

between operator stations contributes further to this flexibility.

FEATURES

• 26” (1920 x 1200 pixel) flat panel colour display (TFT)

• Manual and automatic radar target acquisition and tracking

• Vector charts displayed as underlay to the radar video (in the

Radar application)

• Radar video displayed as chart overlay (in the ECDIS

application)

• Conning information adapted to the current mode of operation

(track steering, docking, dynamic positioning)

• Three colour palettes (Day, Dusk, Night) for easy adaptation

of the display to ambient light conditions

• Remote control of the autopilot in Heading, Course and Track

modes by means of a dedicated operator panel

• Planning and monitoring of sailing routes

• Operator panel with analogue adjustment for gain and clutter

settings (in the Radar application)

• Sharing of charts, sailing routes and AIS targets with other

K-Bridge operator stations across a local area network

• ENC: S-63 and S-57 Edition 3 (official charts)

• Vector charts: AVCS (UKHO), Navtor, Primar, Jeppesen/C

Components

The basic EM 2040P has three units: A sonar head, a

processing unit and a workstation.

The sonar head has bumpers in the corners of the face of the

transducer to protect the it if it is placed on deck, and it has

carrying handles on the sides.

The EM 2040P can be delivered with the standard processing

unit or with a splash proof (24 VDC) portable processing unit.

For completeness, data input from a motion sensor and a

positioning system is required. As is the sound speed profile

of the water column between the transducer and the bottom.

Sound speed at the transducer depth is an optional input.

Optionally, the sonar head can be delivered with mounts for

motion sensor and sound speed sensor, factory aligned for ease

of mounting.

All electronics are contained in the sonar head which is

interfaced to the processing unit via GBit Ethernet. The

processing unit also supplies 48 V power via the same cable.

Operator control, data quality inspection and data storage is

handled by the hydrographic workstation running SIS software

or by 3rd party software.
