"DATA PROCESSING, PLANNING AND ANALYSIS OF VESSEL TRAFFIC IN THE BULGARIAN VTS ZONES" INFORMATION SYSTEM

The "Data processing, planning and analysis of vessel traffic in the Bulgarian VTS zones" information system (VTS database) was developed for the "Ports Infrastructure" Company. The system is a key module of the national Vessel Traffic Management and Information System (VTMIS). The main role of the system is to provide information services to external users - state authorities (Border Police, Navy, Customs) and private transport companies.

The system consists of two main modules:

  • The "VTS operator" module - interfaces and forms for entering and editing of vessel traffic related information
  • The "External user" module - query forms, report and analysis generators

VTS Database

The main features of the system are:

  • Maintenance of database with information on ships that have visited the ports of Varna and Bourgas
  • Database with information on the maneuvers executed between the open sea, the berths and the anchorage areas
  • Meteorological database
  • "Events log" (operating hours of the ports, problems with the navigation equipment, accidents, etc.)
  • Report generators (access via a corporate network and the Internet)
The system includes a geographically distributed database (local database servers in Varna and Bourgas) and a main database server, which replicates the information from the local servers in real time and supports the database backups.

The project was developed by use of open-source products (Linux OS and MySQL database). All user interfaces are web based and platform independent.
