Risk of an accident is an ever-present component in the maritime transportation process, especially in congested waters such as port areas. Since safety is of crucial importance in the maritime industry, different models of risk assessments were developed to ensure minimal navigational danger. The aim of this paper is the development of modular, dynamic sets of parameters, applicable for future risk assessment models on port approaches by introducing top-down expert appraisal structure methodology organised in three steps. Firstly, approaches and criteria from relevant international recommendations and scientific studies on maritime risk assessment models were analysed and compared, in order to obtain general categories of navigational safety parameters. Secondly, existing risk assessment parameters were structured and combined into new dynamic sets. In the third step, these dynamic sets of parameters were selected, and numerical values were assigned to them according to the specific context of the port. Finally, this top-down methodology aims to provide relevant dynamic sets of criteria for navigational safety risk assessment development that are flexible and widely applicable for the needs and characteristics of different ports.

The growing demand for transportation has brought even larger quantities of traffic in spatially limited port areas. Considering a diverse traffic mix, infrastructural overcapacity and busy schedule, port communities have started to face possible degradation of safety and environmental standards. To mitigate these problems, a number of different monitoring solutions of marine environment were deployed. Since conventional environmental and traffic data gathering by physical monitoring and sampling was logistically complicated and inefficient in time and resources, different approaches had to be considered. With the rise of accessible Internet of Things (IoT) technology some ports already installed smart monitoring devices such as smart buoys. The goal of this paper is to examine the concept and benefits of an automated smart buoy as a cost effective, easy to install device capable of real-time remote information sharing. Furthermore, the design and operational processes of existing automated smart buoy will be presented, along with solutions for tackling navigational safety and environmental problems.
