Abstract

To secure a safe anchor riding under stormy weather, the captain judges to use both bower anchors for reinforce the holding power or judges to use a single anchor with dropping another bower as a short-scope anchor. If the swing control of a ship can be done, the power of wind pressure can be reduced. Then, the ship will maintain a safe anchor riding. Training ship Fukae-maru, the faculty of maritime sciences Kobe University, adopts CPP (Controllable Pitch Propeller) as a propulsion system. So, she can control the propeller thrust, ahead and astern, easily. Various experiments about the swing control of a ship were done by using astern thrust of it. As a result of the analysis, the suitable astern thrust was effective on the swing control of a ship because of the reduction of swing room and wind pressure. The authors are expecting that this analytical result will be useful as one example concerning swing control of a CPP ship under stormy weather.
