Overview of safety aspect into ports: port tug impact research

Abstract

To ensure safety in a port big role takes port tugs which made major important jobs such as escorting vessels, assist for big vessels to help them maneuvering during entering into port and leaving it, help during mooring and unmooring operations, breaking ice in port channel, works in firefighting and rescue operations. In many case quantities of necessary tugs or tugs power decisions are made from experience and is not optimal. This paper present research of port tugs impact for port navigation safety results, while traying to optimize in exact case necessary number of tugs and tugs power depending on vessels parameters and external conditions to use ship handling mathematical models. Finally, conclusion and recommendations presented in the end of article.
