Real time data and ECDIS in a web-based port management package

摘要

The web-based port management package recently developed for Port of San Diego by InterOcean and SevenCs companies offers harbour authorities new possibilities through real-time navigational and environmental data inputs and access to the land-based data bases for ECDIS presentation through the Internet. The data are presented on top of the Electronic Navigational Chart (ENC) in form of thematic overlays using ECDIS technology. The real-time information transmitted from the environmental sensors includes weather, currents and tidal heights. Tidal data are used also to provide the real-time, dynamic under-keel clearance information in the ship manoeuvring areas. The data are supported by the web-camera images with zooming and panning capability and, in near future, by the radar overlay and AIS information. Updated ship arrival and departure information is included together with static data showing relevant regulatory information, emergency response information, lists of facilities, fees, and marine events, etc. for the general public. The information can be accessed from any computer equipped with a Web browser, e.g. by Pilots navigating an approaching vessel, from the Port Authority offices, Coast Guard marine safety office, and by general public. The access is controlled by a multiple level password structure. Unlike the navigational applications, there are no regulatory restrictions on the port or coastal information systems and variables can be dynamically presented. They can include meteorological and oceanographic data and depth adjusted for tides and surges. In addition to port management, practical applications can include presentation of coastal flooding predictions. ECDIS-type software may become a tool not only for port or coastal zone managers but also for insurance offices. Basing such systems on the web provides the general public with access to important information. This paper describes the system and discusses the advantages it offers to port authorities not only in traffic management, but also in pollution control, safety, and public information. Future developments and enhancements are also proposed. Current trends indicate that this system, similar to PORTS and other CO-OPS initiatives of NOAA, will provide the basis for even more seamlessly-integrated and cost-effective real-time information systems for other ports. Ports and harbors similar to San Diego can be ideal candidates to benefit in many ways from the implementation and operation of the system described herein.
