This study is to calculate the Real-Time Overlapped Area of ellipses with weight by Ship's Bumper Theory. In this paper, The Real-Time Overlapped Area of ellipses with weight can be used the important tool to feel the perceived risk evaluation by navigator. In this paper, through how to feel the risk of collision between the vessels in advance, We will study the technique to certify the perceived risk of collision from several different angles.

This study is to calculate the Real-Time contact point of ellipses between the vessels ships by Ship's Bumper Theory. The Real-Time contact point of ship's bumper ellipses can be used the important tool to feel the perceived risk evaluation of ship's collision risk by VTS operator. In this paper, The warning information to feel the risk of collision between the vessels in advance is able to help them for VTS operation, We will study the technique to certify the perceived risk of collision from several different angles by programming.
