Abstract

Side launching is a hectic and dynamic process. Once the procedure has begun, there is no stopping it and one can just hope the best. Unfortunately there is a serious risk of the ship getting damaged in the course of action. In shallow water the ship can capsize if the heeling angle is too large. If the ship is launched to slow it will fall back risking its chine hitting the slip way with damage to the bottom of the vessel. Therefore the management until the actual launch is crucial to get a successful launch. For ages now (uniform) ships have been produced and side launched in the Netherlands. It didn’t matter if the ships were made of wood or metal or the slope was rather flat or a bit more steep. By centuries of experience the management was good and the side launch well prepared. The side launch often proved to be successful. Indeed it was a weekly returning event and the many experiences were passed on from one worker to the other. However, nowadays the production of uniform ships is moving to cheap labor countries for obvious reasons. This movement threatens the continuation of Dutch shipyards. A number of shipyards have chosen to change their production to custom made ships, but this leads to other problems. These days the side launch has become a rare occurrence in the Netherlands and workers with experience are often retired. The changed parameters are becoming a risk and management is getting more difficult. Shipyards are in need for a methodology that can predict the outcome of a side launch, such that ship builders can in advance alter the parameters of the launch if needed and again minimize the risk of a failed side launch.
