There are no design rules for cofferdam structures. Research has been carried out to close this gap by developing a design procedure for cofferdam structures in a semi-probabilistic way, close to sheet pile guidelines. During the past few years a complete probabilistic analysis tool has become available as part of an existing FE code. With this code, a full stochastic analysis of a cofferdam structure example may be demonstrated. The paper shows the results of the probabilistic code and compares the results of this stochastic analysis with the results of an analysis based on the design procedure.
