However, several aspects regarding ship collisions, i.e. the probability of occurrence of a collision, the magnitude of the collision force and the influence on the safety of the pit, are uncertain. The goal of this research is to develop a method to determine the safety of a temporary construction pit. The Blankenburg Connection, which is being built by BAAK, is used as a case study in this thesis. The construction pit in this project is located in the Scheur and has to deal with a busy navigation channel. The end-wall of the pit is a temporary wall, as it has to be removed in order to to be able to float a tunnel element to the middle of the channel.A Bayesian Network is used as a method to take into account all the different parameters influencing the probability of collision. When comparing the outcome of the model with values based on historical data for the Scheur, it can be concluded that the model predicts the probability quite well. A small difference can be noticed, which is probably explained by the fact of under-reporting. To determine the magnitude of the force, a Monte Carlo simulation is used. In this way a probability density function of the magnitude of the force is generated, giving insight in the occurrence of forces on the structure. The resistance of the structure is determined and mitigation measures to increase the safety of the construction pit are examined.
