heal.abstract	In this thesis, the feasibility of implementing an alternative dynamic positioning system design into a high-speed rescue vessel with no blades or potential harmful gear, is investigated. The vessel will be ultimately given to the Hellenic Coast Guard for further enhancing their rescuing operations. The work described can be divided into two main parts. The first part is concentrated in building a simulation model, comprised of a vessel model, environmental loads model and a PID controller, which will be simulated using the MatLab Simulink environment, so as to confirm the potential application of the system proposed. The simulation scenarios are defined based on the typical weather conditions that are encountered during dynamic positioning operations in open seas. The second part is devoted to preparing a smaller test boat, which will be used for testing the alternative DP system design before installing it on the final vessel. This part's targets are, firstly, to properly install the DP system on board, and secondly, to build a measuring device, named as data logger, which will include an inertial measurement unit (IMU). The device will be programmed and calibrated, in order to install it on board and measure the position and heading of the vessel during the initial sea experiments. It was decided to omit the use of a GPS unit at this stage, in order to exploit the possibilities of position estimation, only with the aid of small sensors installed on board.	en
