Automatic procedure of side ship launching calculation

The side launching method has become a solution of transporting ship into water in restricted water/canal. Unfortunately, this method brings higher possibility of capsizing mainly occurring when the ship interacts with the water surface. Shipyards need detailed calculations and procedures to predict...

description The side launching method has become a solution of transporting ship into water in restricted water/canal. Unfortunately, this method brings higher possibility of capsizing mainly occurring when the ship interacts with the water surface. Shipyards need detailed calculations and procedures to predict the outcome of ship in water, yet they are not able to perform due to its complexity of computation and its being time-consuming. Thus, this thesis proposes the automatic procedure of the side ship launching. Using the gravitational side launching theory, a code has been developed to solve the 3D launching case. Computation of ship motions, velocity and acceleration are conducted to predict the actual ship simulation. To simplify things, three phases of analysis are introduced corresponds to the kinematics behaviour of the object when interacts with water. From this study, the result shows a good agreement in comparison to shipyard calculation results with less than 5% differences. However, to be applied in shipyard, this simulation should be done further for the dynamic motion to capture all aspects.
