Effective Ship Domains Considering Ship Encounter Situations and Speeds
Abstract Ship domain is an important concept in assessing navigation situation and planning collision avoidance manoeuvres of a ship. For purpose of improving the precision and adaptability of the ship domains, effective ship domains are proposed for ships with different speeds in a variety of encounter situations in this work.

A statistical study of ship domains [PDF]
The thesis is an attempt to establish the water area required by any one ship for safe and efficient navigation. The concept of a ship domain has been considered, which may be defined as the effective area around a ship which a navigator would like to keep free with respect to other ships and stationary objects.
