The project PROTIDE

PROTIDE is developed in cooperation between DVS and Charta Software with the intention of implementing a state-of-the-art tidal window calculation route. The initial idea was to make a method based on the research of Ruud Bouw ('Admittance policy tidal bound ships'), which was a study to find a truly probabilistic methodology as an improvement on the currently used HARAP model. The objectives:

1. Introduce a model that can be used real-time
2. Use actual forecast data instead of schematizations for water levels, swell and current
3. Use a continuous/actual data for the channel layout, channel depth reductions and ship dimensions
4. Use state-of-the art ship motion analysis
5. Analyse and use a safety criterion for each individual ship entrance

These objectives where analyzed in an initial feasibility study (phase 1 - 2007) with interested parties and end users. Later the feasibility of the designed calculation method was investigated (phase 2 - 2008) and finally the work started to transform the developed prototypes into a application suitable for production (phase 3 - 2009). The milestones are listed in the News section on this website.
