ABSTRACT

The International Maritime Organization (IMO) has set some criteria for the maneuverability of ships, in order to ensure safety at sea and keep collusions that may lead to pollution to minimum level. In this part of the two-part paper, maneuverability standarts for ships that IMO has specified and the standard maneuvering tests that have to be done to meet these criteria have been investigated. Some information has been provided about why the maneuvering tests are performed and how their results should be interpreted. It is also theoretically explained how to decide whether a ship has the turning ability and straight line stability. Lastly, the internal and external factors that influence the maneuvering performance estimation of ships were examined and some results given in the literature were interpreted briefly.
