MARIN Predicts Dredge Downtime

The maritime research institute MARIN in Wageningen, the Netherlands, has developed a numerical model and computer program, now in prototype stage, for use by dredging contractors to predict downtime due to weather when dredging in the open sea. The weather is simulated by a wind-wave model. The model combines wind and wave patterns with wave proliferation parameters such as bottom features, currents and blockages, to produce an accurate prediction of wave action. Using information on the forces that working cutterhead dredges and trailing suction hopper dredges can withstand, the program predicts the amount of time a dredge will be unable to work because of heavy weather.
