Present Bridge Clearance

Introduction/Additional information: 

Introduction:

This message shall be sent from shore only, to inform dynamically about the about the actual minimum vertical clearance of a certain bridge opening. The information shall be displayed on an external display such as Inland ECDIS.

Additional Information:

  • This message should only been send by a competent/waterway authority from shore only.

  • The ISRS code indicates the position of the bridge opening and shall allow the match with the IECDIS display. It consists of UN country code, Fairway section number, Object code and fairway hectometre as published in the ISRS code as part of the RIS Index published in the European Reference Data Management System (ERDMS).

  • The bridge clearance value is the actual measured distance from the water surface to the lowest part of the bridge opening according to the width of the fairway given in the RIS Index / IENC.

  • The ”minutes of the day” provide the absolute time of measurement in minutes since UTC midnight and therefore allow an unambiguous transmission of the age of the data up to 24 hours.

  • It is recommended that the values transmitted are not older than 1 hour.

  • If an accuracy information is provided it has to be subtracted from the given actual bridge clearance in worst case. It must by no means seen as indication of additional actual bridge clearance
