A group within the STM project, consisting of Fredrik Olindersson (Chalmers), Tina Scheidweiler, Wilko Bruhn (both Fraunhofer CML), and Axel Andersson (SSPA) was formed to develop a real-time Maritime Safety Index. Based on maritime expert judgement, ship traffic is assessed with regards to safe navigation. These experts have been identified as being either active or retired navigators, pilots, lecturers and simulator instructors. In order to capture their assessment of what is considered to be “safe”, multiple various traffic situations in both open and constrained waters are graphically presented in an on-line survey. The respondents are to judge each traffic situation from the perspective of their identified “own ship” on a scale from 1 to 10.

With the feedback from the survey, the index is then developed using fuzzy logic modelling and further validated in different ship handling simulator scenarios by maritime traffic experts. Numerical data from the simulator is used as an input to assess the present traffic situation from the perspective of a specific ship and outputs a comprehensive index.

In the STM project, simulations within the European Maritime Simulator Network (EMSN) are scheduled to start during autumn 2017 with exercise scenarios consisting of 25-30 manned ships navigating in a ship handling simulation environment. Exercises will include scenarios such as complex traffic situations with and without the use of the envisaged STM tools. The numerical model based on the expert judgement in combination with human factors analysis will then be used in the evaluation of the simulations from an operational safety perspective.
