JRC JAN-9201 & 7201 ECDIS


The JRC JAN-9201 & 7201 ECDIS (Electronic Chart Display and Information System) is a geographic information system for voyage planning and route monitoring to support the safety navigation of ships at sea.

The ECDIS onboard a ship uses images obtained from the automatic identification system (AIS), radar system, and collision avoidance target tracking (TT) system and superposes the images with navigational chart information, thus accurately displaying dynamic information on other ships around. Also the ECDIS plays central roles in the safe navigation of the ship and provides safety functions, including the generation of warnings when the ship approaches dangerous areas. The ECDIS is useful for marine accident avoidance and serves as equipment indispensable to the safe navigation of ships.

n response to the latest revision of the International Convention for the Safety of Life at Sea (SOLAS), the International Maritime Organization (IMO) enforced the mandatory installation of the ECDIS on oceangoing passenger ships with 500 gross tons or more and tankers and cargo ships with 3,000 gross tons or more in a stepwise manner in and after July 2012. This mandatory decision requires conventional paper charts or an additional ECDIS as a backup to the primary ECDIS if a ship uses the primary ECDIS as main navigational equipment. (Requirements for the equipment and operation qualification are subject to approval from the country with which the ship is registered and recommendations from the classification society of the ship.)
The new JRC JAN-9201 & 7201 ECDIS has integrated route editing, which was conventionally divided into two segments, i.e., graphics input and numeric table input areas, into one. Waypoints, if specified, on a navigational chart are immediately quantified and added to the numeric editing table, and the numeric data on the waypoints that is input into the editing table is immediately reflected on the navigational chart. Up to four routes can be edited at the same time, and a portion cut out of any route can be combined and the routes can be all or partly replaced or edited.
Furthermore, a safety check on edited route data is possible with a click of a button. Detected error information items, if any, are listed and displayed, and the corresponding route portions are highlighted in the chart and table, which can be confirmed at a glance to take remedial measures.
