ECDIS

ECDIS as an Anti-Grounding Tool

ECDIS can be used as a very effective Anti- Grounding tool when properly set up and used along with appropriate sensors.

The vessels position can be continuously monitored on screen. This facility combined with 

On ENC’s alarms can be generated well before the vessel would run into any danger.

In narrow and congested waters the picture by the ECDIS can effectively influence the action taken onboard by the ..... Difference between a vessel aground (or) afloat.

Positive identification of landmarks / navigational aids /buoys/vessels in conjunction with RADAR Overlay to ascertain the quality of sensor input (Position / Echo Sounder / etc.)

Use of true vector, RADAR Overlay &  Echo Sounder alarms can effectively help navigate safely under / tidal conditions where vessels are experiencing severe set.

  As per IMO performance standards, an ECDIS should have the min.inputs of

• An Electronic Position Fixing System (EPFS)
• To a gyrocompass (HEADING)
• To a speed and distance measuring device (SPEED)

Advantage of  ECDIS over paper Chart:

—  Position fixing can be done at required interval without manual interference

—  Continuous  monitoring of the ships position

—  When interfaced with ARPA/RADAR,target can be monitored continuously

—  If two position fixing system are available,the discrepancy in two systems can be identified

—  Charts can be corrected with help of CD/online

—  Passage planning can be done on ECDIS without referring to other publications 

—  Various alarm can be set on ECDIS

—  Progress of the passage can be monitored in more disciplined manner ,since other navigational data is available on ECDIS

—  Various alarm can be activated to draw the attention of OOW

—  More accurate ETA can be calculated

—  Anchoring can be planned more precisely
