“Minimum entrance width for inland ports”| Professor of graduation: Prof. Ir. T. Vellinga , supervisors: Ir. H.J. Verheij (TU Delft), Ir. D.J. Peters (TU Delft), Ir. D. ten Hove (MARIN)

Currently, guidelines are missing for the design of inland port entrances along flowing waters with flow velocities larger than 0.5 m/s. In the near future, Rijkswaterstaat wants to provide design rules for inland port entrances along these flowing waters in the Netherlands. A more generic insight in the most efficient entrance can reduce the design costs and time. The objective of this research was to determine the minimal required nautical safe entrance width of inland ports for generic situations along flowing waters in non-tidal areas. To find this minimal entrance width, the most efficient entrance layout should be determined. With ship manoeuvring simulation systems, the nautical safety of different scenarios can be analysed. The fast-time simulation model SHIPMA was used to study the influence of multiple design aspects. It resulted that an entrance angle of 120 degrees at the downstream corner is most efficient. Note: an entrance mouth orientation to downstream direction. This was found for allowing ships to manoeuvre backward into the port, for arrival scenarios sailing downstream. Moreover, a linear relation was observed between the flow velocity and the required entrance width. This research provides a first insight in the most efficient inland port entrance. Not all the design aspects that can possibly influence the required entrance width were included. Recommendations were done for further research.
