説明

A container ship with much larger structure above sea than the hull volume under water is strongly affected from wind at sea. It is important to estimate wind effect exactly for assessing navigational performance of the ship. Ordinary, specification of a ship external form does not change without considering the main hull's thickness that means the height from sea level to main hull deck top. On the other hand, the container ships have many kinds of on-deck forms depended on the number of containers. Under these situation, it is difficult to reflect individual shape influence on the deck of a container ship in the estimation method, since the method is basically proposed using fully loaded or ballast ships' experimental results and only uses the simple ship external form parameter, that is total projected area, center potion of the projected area for lateral area above sea etc. In the present, there is no estimation method to calculate the wind effect easily by the external ship form specification including the lack influence of the containers at some parts on deck. Then, the authors carried out the wind tunnel experiments of a container ship for the many kinds of stowage of containers on deck in order to grasp the aerodynamics specifications of them. Using the experimental results, authors propose a new estimation method for wind forces on no fully loaded container ships. This new method is able to estimate the longitudinal and lateral forces and yaw moment on wind load for several kinds of container ship forms more exactly rather than the previous estimation method.
