| Abstract |
The transformation of inland shipping towards an automated mode of transport with clean propulsion concepts is initiated. While the path of automation with its intermediate steps is largely defined and first solutions for partial automation and remote control are available on the market, the race for technologies to decarbonise the drivetrain is completely open. However, it is evident that the operating costs of the drives and the investment costs for the drive power will increase significantly. As a result, the expected decline in the availability of power reserves for critical situations links the topics of automation and decarbonisation. Both fields of research require an improved knowledge of the manoeuvring behaviour of existing and future inland vessels. Free‐running manoeuvring tests in model scale are of great importance in this development process, offering direct insight into manoeuvring characteristics. For example, evasive manoeuvres according to the European Standard laying down Technical Requirements for Inland Navigation vessels (ES‐TRIN) are mandatory for ship’s a pproval. In order to meet this increasing demand, a novel concept for this type of test has been developed at DST. Manoeuvres with a wooden model, equipped with remote‐controlled propulsion and steering systems, are performed in front of the towing carriage. An optical motion tracking system tracks the model’s movement, which is converted in real‐time to full‐scale GPS coordinates, enabling the use of real‐world navigation t echnology. The technology integrates a rate‐of‐turn controller, a track‐control system, and other automated functions for precise rudder control during predefined manoeuvres. Special attention is given to improving the reliability and repeatability of these tests, achieved through partial automation of the manoeuvres. A special focus of this paper is the investigation of the manoeuvring performance of ship models in shallow water condition and different water depths. Based on ongoing and completed research projects, examples of the system application and the results obtained are presented and discussed. In addition to evaluating the results in relation to ES‐TRIN requirements, the findings also serve as a valuable basis for refining mathematical manoeuvring mo dels. By ensuring repeatable and reliable model‐scale manoeuvres, the accuracy of full‐scale manoeuvre predictions can be enhanced, along with a deeper understanding of potential measurement uncertainties. |
