Prediction tools are very helpful and already in use on ships for a long time, beginning with trail modes in ARPA radars up to curved headline overlay in ECDIS. However, the simplification of these predictions allows restricted use only based either on estimated future courses & tracks or on the simple integration of the current ship motion not including the immediate response on changes of rudder and engine commands. New concepts for on board displays and simulation tools were developed in two research projects, funded by the German Federal Ministry of Education and Research and the Federal Ministry of Economics AND Technology together with partners from manufacturers like SAM Electronics Hamburg and INTERSCHALT/AVECS. A prediction tool was developed to simulate the ships motion with complex dynamic models in fast time and to display the ships track immediately for the intended or actual rudder or engine manoeuvre. These simulations are based on input from the ships actual sensors via the Voyage Data Recorder or integrated bridges systems. Furthermore the information from diagnosis tools will be taken into account by analysing the status of the manoeuvring facilities and providing information in case of failures e.g. reduced engine power or larger rudder response time due to malfunctions of the equipment. The parameters of the equation of motion can be estimated by a fast time simulation program and data analyser used for tuning of ship models in the ship handling simulator. In the paper and presentations the methods will be described and examples will be given for results from test trails in the full mission ship handling simulator of the Maritime Simulation Centre Warnemuende upgraded in 2007/2008.
