Securing safe maritime transport route and preventing maritime accident through safe and efficient vessel traffic management in the ports and the major vessel passage routes.

Increasing the efficiency of port operation through effective management of port facilities and vessels traffic, with the capability of determining priority of berthing/unberthing of vessels, designating the position for berthing and anchorage, and supporting pilotage, towing, etc.

Identifying the maritime traffic situation for entering and departing vessels and sailing vessels in the water.

Controlling the vessel traffic in order to prevent maritime distress for instance, navigation course deviation, approaching to hazardous area, peril of collision, etc.

Providing maritime traffic information which includes vessels’ sailing status, plans for operating pilotage service and tugboat, and operational information for ports which includes port facilities, anchorage, etc.

Providing security information for navigation like tidal current, tide, meteorological information of the sea for the sake of vessels’ safe sailing.

Aiming to improve productivity of port operation by facilitating maritime logistics via systematic and efficient vessel traffic management and securing international competitiveness of the ports.

Preventing maritime distress and protecting marine environment by maintaining maritime traffic order and securing safety of vessels’ sailing.
VTS sensor server(VSS) collects data from one or more sensors, transforms and multiplexes the data into a format suitable for use in the system. Sensors are controlled by the operator with sensor control program VTS at Operator Console (VOC), then transferred to VSS for sensor control.
VTS

 

VTS sensor server(VSS) collects data from one or more sensors, transforms and multiplexes the data into a format suitable for use in the system. Sensors are controlled by the operator with sensor control program VTS at Operator Console (VOC), then transferred to VSS for sensor control.
Radar Control System
The Radar transceiver and antenna is controlled at remote by PLC(programmable Logic Controller) and is used to monitor and control radar systems and provides for the following:

Collection of radar equipment status

Display of radar system status

Local or remote configuration of the radar system

AIS
The Automatic Identification System (AIS) interface is used for

Collection and integration of transponder targets from the base-station(s).

Integration to the VTS radar tracked targets.

Sending and Receiving of text messages.

For controlling equipment at base-station requires separate application in administration mode.
VHF DF
VHF Direction Finders is used to provide the VTS operators with accurate bearings to vessels communicating on selectable VHF channels from detecting equipment. The VHF/DF interface provides for the following:

displays of DF strobes superimposed on the VOC chart.

Operator control of DF features such as channel selection and channel frequencies

Local and remote monitoring of status of system operation.

Met/Hyd
The Meteorological & Hydrological interface is used to integrate meteorological and hydrological sensors into the operator console.

Collection of meteorological and hydrological data from remote sensors

Display of readings on the client workstations

Logging of applicable data

SCADA
The Supervisory Control and Data Acquisition (SCADA) interface is used to collect the information (intruder alarms, fire alarms, power failures, air condition failures, high or low temperatures on equipment and in equipment rooms, etc) from remote status and transfer to WIS (Warning and Integration Server).
CCTV
The CCTV server employs frame grabber techniques together with advanced image compression to transfer still pictures from the camera over the LAN or WAN. The CCTV server also provides for remote control of the CCTV camera from a client workstation.

 

VET is used to extract digital radar video and target track information from the analogue radar signal.
Radar Echo(Plots) Generation
Digital video is extracted from analogue radar video generated by the Radar MTR( a modulator-transmitter-receiver).
Target Tracks Generation
target track is immediately generated by command either operator or automatically by defined value for creating target information like position, speed and azimuth.
LAN communication
The digital video and target tracks are transmitted to the VTS control centre over a Local Area Network (LAN). If the radar site can be controlled at a remote location.

 

The Warning and Integration Server collects tracking information on targets and surveyed navigational aids (navaids) from all radars and AIS transponders, and distributes the integrated view to each VOC and log server. WIS also monitors the targets and navaids against a set of warning criteria, and issues warnings when specific criteria are violated.
Integrator Service
The WIS collects the geographical position of the targets information from VET and AIS base station and generate an Integrated Target Table (ITT). The ITT data is distributed to the VOC Operator Workstations, VRD, VLR, DEB.
Target Attribute Service
The WIS continuously monitors each integrated target and navaid against a set of criteria, and defines and generates a warning or specific information according to predefined criteria and distributes to subsystem.
System Monitoring Service
The WIS monitors the other VTS system components for irregularities, and reports via the LAN any detected failures or lack of response from VTS components. Present System Warnings are presented on request at the VOC display.

 

TThe VOC displays all the information collected from sensors (radar image, AIS information, Met/Hyd, VHF DF) and integrated warnings on Electronic Navigational Charts (ENC S.57 Edition 3. Format), and gives the VTS operator access for surveillance task together with the ability to control system functions.
ECDIS
Electronic Chart Display and Information System (ENC S.57 Edition 3. Format) that displays on computer monitor
Radar Display
The radar video presented in ECDIS on VOC is digitized radar images, derived from the remote.
Track Display
display of Radar target tracks and AIS target tracks
VHF DF Display
Display of Bearing lines from VHF/DF bearing lines
Met/Hyd display
Display of Met/Hyd Data collected from remote Meteorological/Hydrological sensors
Infolink to Database
Detailed vessel and navigational data via infolink to VTS database or Port-MIS

 

The VRD provides an alternative to the VOC when VTS related information must be available to other personnel or parties (navy, coast guard) on a "read only" basis.

 

VLR logs in real-time VTS related data from sensors and servers and DEB replays the situation what occurred at a specific time with use of log files and support the analysis of operator actions. Following can be recorded and replayed as part of the VLR.
Radar Echo(Plots) Recording
Radar image and information received on real time is saved at a regular interval (normally 20 sec, adjustable) in order to be replayed when necessary
Tracks Attribute Recording
Track attributes (Radar track or AIS track) received on real time are saved in server in order to be replayed when necessary.
VHF DF Recording
Operators VHF communication is saved in server after digitalized and replays on independent replaying facility or its own server.
AIS text messages Recording
AIS text messages received and transmitted through AIS Transponder is recorded.

 

VTS database is a SQL system that stores and provides detailed vessel information (shipmaster, vessel type, cargo type) and navigational information (history, vessel information board). VTS operator can browse, search and change stored data stored in DB via VOC Infolink as well as internet web browser.
