The objective of the project is two-fold. Firstly, to develop a safety criterion for safe passage in ship-ship encounter in high seas and coastal areas. Secondly, criterion implementation within a Decision Support Tool (DST) for onboard and ashore use. Supporting collision avoidance manoeuvring, from the perspective of ship and shore-based centres, such as Vessel Traffic Services (VTS) and Fleet Operation Centres (FOC). The safety criterion will delineate the required area for a ship to perform safe collision avoidance manoeuvre in the high seas, as well as the time of its execution. Two types of manoeuvers could be distinguished:1) Vessels collision-avoidance at the minimum though safe distance when their hydrodynamics are taken into consideration;2) The evasive manoeuvre that is executed when navigator operates intuitively in his comfort zone. The latter can be defined as a manoeuver that is well known to the crew and frequently practised in a ship-ship encounter. This is essential, since in the course of so-called last-chance manoeuver the performance of a crew that already acts under high pressure may be negatively affected, thus the quality and effectiveness of such manoeuver may be compromised. Additionally ship stability or weather conditions may not allow for this type of manoeuver. Thus the last-chance manoeuver cannot be seen as fully safe either for cargo nor crew. Moreover, this project will research the impact of this criterion for application in shore-based maritime traffic surveillance and management services i.e. VTS, FOC applying e-Navigation infrastructures with enhanced facilities for data exchange. To define the safety criterion, covering all relevant aspects of marine navigation, we will adopt a hybrid approach, combining, first, the computer simulations performed with the use of two advanced tools, and second, experts’ judgment. The former adopts the state-of-the-art six-degree of freedom hydrodynamic model of ship motion for a selecte
