Navdec Decision Support System to Avoid Collision and Distress in Sea Navigation

This paper proposes an advanced navigation decision support system (NAVDEC) mainly to avoid the collision among two or more vessels in sea. More commonly the faults can be occurred by the mistakes of human where it can be avoided by the decision support system. Decision can be taken by the navigator in critical situations with the help of the gathered information from different identification and tracking system. The planning of routes is more important to maintain the proper navigation in sea. The proposed system also uses the Ant Colony Optimization algorithm for planning the routes in collision time. In addition to this GDMSS of very high frequency management system can be used for the safe navigation and the data collection can also be sent to the coastal through the high frequency. Pollution in navigation can also be reduced automatically with the detection and avoidance of collision among the vessels in sea.
