Electronic Chart Display and Information System (ECDIS)

ECDIS IS AN ANTI-GROUNDING TOOL

• ECDIS can be used 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 Radar Overlay and PI function can assist the navigator in continuous cross-verification of vessel position by alternate means (GNSS / RADAR) 
• On ENC's alarms can be generated well before the vessel would run into any danger.
•  In narrow and congested waters the picture provided by the ECDIS can effectively influence the action taken onboard by the navigator difference between a vessel aground (or) afloat.
• Positive identification of landmarks / Buoys / Navigational Aids / Vessel targets 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 heavy weather /tidal conditions where vessels are experiencing severe set.

NAUTICAL TERMS

I hereby posted some of the nautical terms for the convinence of seafares ..

CRANES AND DERRICKS

                                                               CRANES

Both overhead travelling cranes and gantry cranes are types of crane which lift objects by a hoist which is fitted in a trolley and can move horizontally on a rail or pair of rails fitted under a beam. An overhead travelling crane, also known as an overhead crane or as a suspended crane, has the ends of the supporting beam resting on wheels running on rails at high level, usually on the parallel side walls of a factory or similar large industrial building, so that the whole crane can move the length of the building while the hoist can be moved to and fro across the width of the building. A gantry crane or portal crane has a similar mechanism supported by uprights, usually with wheels at the foot of the uprights allowing the whole crane to traverse. Some portal cranes may have only a fixed gantry, particularly when they are lifting loads such as railway cargoes that are already easily moved beneath them.
