User tests with captains and pilots have been done in the full mission bridge simulator at Chalmers University of Technology, Sweden.
|
Tests showed showing positive results and the users gave positive comments. However some commented that intended route negotiations should not be used in COLREG situations.
|
An interesting new behavior was detected during those simulations. Without having been told so, the OOWs started to move waypoints ahead of their position to “negotiate” a clear passage as soon as they realized that they were on a collision course with the other vessel. This new behavior needs to be investigated in depth to find out if it poses any threat to safety.
