“…All (seagoing) ships which call the port need to travel through the Western Scheldt access channel (figure 4). This 80 km long fairway is considered shallow (h/T < 4, ITTC), and in some stretches, ships will sail at a minimum allowed UKC of 12.5% [8]. This shallowness, in combination with the tidal influence (water level), makes that ships with drafts above 13.1 m are limited in their allowed tidal window.…”

The paper describes the definition and usage of autonomous ship control systems in shallow and confined water. The application of such control system is shown in a case study : a systematic analysis of ship transits in the approach channel to the Port of Antwerp (Western Scheldt) .The control algorithm not only is capable of correctly navigating the ship through the fairway, it also delivers insight in rudder and propeller usage in function of the tidal conditions. Such control systems are validated based on model tests carried out in towing tanks. Flanders Hydraulics Research (FHR) has recently inaugurated their second towing tank, the Towing Tank for Manoeuvres in Shallow Water. One of the functionalities of this facility is the role it can play as test basin for autonomous shipping. Next to the further validation and expansion of existing control scenarios, it will be used to model interaction events between multiple ships. A numerical effort to model interaction events is presented, which will be validated in the model test basin.
