Abstract
The future development of the harbor is influenced by many factors, namely port operational efficiency, port safety, weather condition, national, economic growth rate, and political stability. Although operational efficiency is important; however safety is even more important than operational efficiency. From this point of view, Kaohsiung harbor will soon launch its vessel traffic management system. Piloting service is one of the crucial elements in the development of a port VTS. This article analyzes pilots service behaviour in the Kaohsiung harbor and proposes appropriate pilots management regulations in the future VTS mechanism.
