Applications for SIL and HIL testing in design, verification, and validation of marine systems are expected to increase. With this in view the concept for a mobile simulation system is presented, which aims at enhancing factory and on board simulation based testing. A modular network-based system architecture is proposed providing: real-time process simulation, hardware interfaces, test tools, a mobile bridge console, and 3D-visualization. For the purpose of flexible solutions a modular and scalable approach to simulating ship motion in six degrees of freedom is incorporated. Finally preliminary modelling and simulation results from the current design stage are presented.

New Controllers for ships developed for their modern steering devices need new human interaction within the controller interface to make these controllers applicable. To increase their acceptance and usability especially for high precise operations like berthing, a modified path planning approach shall be introduced which originally bases on the established path planning strategy in electronic sea charts. The represented planning procedure dispense on parameter based modelling due to their obscurity while developing electronic tools and their strong variance of cargo ships. Furthermore, this paper describes the underlying data and the transfer of results from the nautical path planning to a modern controller device on the example of the MIMO controller system AdaNav, which is applicable for the complete speed range. The AdaNav controller enables DP equivalent functions for ships being able to traverse. With that approach the authors want to guarantee full responsibility of the nautical staff, the support of mates mental model connected to path planning and manoeuvring behaviour and feasibility to the executing controller.

Modern steering devices for ships lead to an improved control capability and allow independent actions without tugs by mates in use with modern electronics. Within the project AdaNav developed MIMO controller enables DP equivalent functions for ships being able to traverse. The following contribution shows the inclusion of such modern maneuvering quality as computer based assistance system into electronic ship guidance systems like ECDIS. To guarantee fully responsibility of mates the concept bases on introduced planning practice implementing additional waypoints and attributes.

Gegenwärtig in der Schifffahrt eingesetzte Bahnführungssysteme sind nicht in der Lage, Schiffe mit Querschubeinrichtungen effektiv unter verschiedenen Umwelteinflüssen in Revieren zu steuern. Eine Ausnahme stellen sogenannte DP-Systeme (Dynamic Positioning) dar, weil diese für überwiegend meeresbergbauliche Zwecke das zu steuernde Fahrzeug/Plattform ohne Einsatz von Anker- und Mooring- Anlagen auf seiner vorgegebenen Position halten. Mit einer solchen Zielstellung sind die Anlagen daher nicht zum Navigieren/Manövrieren in begrenzten Revieren für Handelsschiffe geeignet. Ihnen fehlt die Integration in eine zur Navigation geeigneten Geo-Datenbasis. Das weiterführende Ziel dieses Projektes besteht daher in der Integration von DP-ähnlichen Regelsystemen am Beispiel des an der Universität Rostock unter Mitwirkung des Projektleiters entwickelten ADANAV-Reglers in die integrierende User-Schnittstelle ECDIS (Electronic Chart Display and Information System), für die seitens der IMO eine Ausrüstungspflicht für neue Schiffe besteht, um die Vorzüge der komplexen Regelung mit denen der modernen Navigation/Schiffsführung zu verknüpfen.

Currently vessels are often equipped with modern steering devices e.g. tunnel thrusters, podded drives, z-propulsion units. A modern steering concepts increase the manoeuvrability of the vehicle substantially. Special manoeuvres for berthing or casting off can be performed by controlling all available aggregates without additional assistance by tug boats, mooring lines or anchors. Furthermore, the reliability of the position information especially in ports and other safety critical areas has been improved by GNS systems and ECDIS. Today warranted position data are available, so that control tasks with high safety requirements can be realised automatically, especially in case of decreased visibility. A deficit of commercial track control systems consists in the path planning method to generate the input values of the specific track control systems by the navigating officer, especially in low speed modes. In order to face this lack, new manoeuvre planning algorithms have been developed and embedded in a simulation and test environment. The feasibility of the developed manoeuvre planning methods is demonstrated with one of the most challenging nautical tasks-the berthing manoeuvre.
