Risk assessment and management was established as a scientific field some 30–40 years ago. Principles and methods were developed for how to conceptualize, assess, and manage risk. These principles and methods still represent largely the foundation of this field today, but many advances have been made, linked to both the theoretical platform and practical models and procedures. The purpose of the thesis is to perform a review of these advances, with a special focus on the fundamental ideas and thinking on which these are based. We have looked for trends in perspectives and approaches, and we reflect on where further development of the risk field is needed and should be encouraged. The present study is written for readers with different types of background, not only for experts on risk. However, there is a conflict between the cost impact and safety aspect. E&P managers as well as government supervisor authorities are constantly faced with decisions to be made regarding of safety. In order to ensure comparability and to set priorities application of QRA is a useful tool to justify choices made with regard to personnel safety, environmental protection, asset damage and business reputation, it is recommended to apply the systematic cause analysis method and develop the risk management models which contains an integral approach toward the health, safety and environmental aspect.

The European Directive 2008/96/CE on Road Infrastructures Safety Management gives great emphasis to road Safety Inspections SI as tool for safety management of existing roads. In this framework, development of surrogate measures of safety derived from data collected during safety inspections can provide a source of information for risk assessment. Furthermore, SIs derived information seems to be promising for road Agencies as a tool to prioritize measures and sections to treat. As a result of a research project funded by the European Union in 2004 and successful application in Italy, a Risk Index RI was developed and available as surrogate measure of safety for local two-lane rural roads. The procedure was adapted to the new Polish guideline for safety inspection and re-calibrated on the local crash type distribution. Experimental application on about 100 km of Polish two lane rural road shows a promising correlation between the RI and the crash frequency.

Dyrektywa Europejska 2008/96/WE w sprawie zarządzania bezpieczeństwem infrastruktury drogowej kładzie duży nacisk na kontrolę stanu bezpieczeństwa ruchu drogowego SI jako narzędzia do zarządzania bezpieczeństwem istniejącej infrastruktury drogowej. W tym kontekście rozwój pośrednich miar bezpieczeństwa ruchu na podstawie danych gromadzonych podczas kontroli bezpieczeństwa może stanowić źródło informacji do oceny ryzyka w ruchu drogowym. Wyniki kontroli bezpieczeństwa mogą również stanowić źródło informacji dla administracji drogowej do optymalizacji wyboru stosowanych środków poprawy bezpieczeństwa ruchu drogowego, a także wskazywania odcinków wymagających interwencji. W tym celu wprowadzony został wskaźnik ryzyka RI, jako pośrednia miara bezpieczeństwa ruchu drogowego dla lokalnych dróg zamiejskich jednojezdniowych dwupasowych, który został opracowany we Włoszech w wyniku projektu badawczego finansowanego przez Unię Europejską w 2004 r. Stworzona metoda została dostosowana do nowych polskich wytycznych dotyczących kontroli bezpieczeństwa, a następnie skalibrowana z uwzględnieniem danych o wypadkach na drogach wojewódzkich, województwa małopolskiego w Polsce. Opisane w artykule badania przeprowadzone na odcinku około 100 km jednojezdniowych dwupasowych dróg zamiejskich w Polsce wskazują na występowanie zależności pomiędzy wskaźnikiem ryzyka RI, a częstością wypadków.

In this paper, two indexes for own ship risk collision assessment in the restricted water are proposed. The first one concerns the collision threats for ships. The second one describes threats that are generated by human error. It is carried out dynamically with accordance to changes in time. To realize the main aim of the paper, the definition of the extended domain of the ship is introduced. Furthermore, the rules to determine the indexes and range of their values are developed. Finally, a comprehensive model and its potential application are presented. There are some important things to take into account during the model development: the interface, the levels and type of the output information, the type and accuracy of the information about the position and movement dynamics of the particular ships. It gives the opportunity to consider the different operation levels. In addition, it also allows us to take into account the different levels of measurement and the collision risk warnings. This approach can be helpful for both the VTS operator and OOW, the ship’s navigator, as the tool to support the safe navigation in restricted water.

Ship collision risk index is the basic and important concept in the domain of ship collision avoidance. In this paper, the advantages and deficiencies of the various calculation methods of ship collision risk index are pointed out. Then the ship collision risk model based on complex plane, which can well make up for the deficiencies of the widely-used evaluation model proposed by Kearon.J and Liu ruru is proposed. On this basis, the calculation method of collision risk index under the encountering situation of multi-ships is constructed, then the three-dimensional image and spatial curve of the risk index are figured out. Finally, single chip microcomputer is used to realize the model. And attaching this single chip microcomputer to ARPA is helpful to the decision-making of the marine navigators.

The paper presents the concept of safety in water distribution systems, which is an important issue connected with its functioning in crisis situations. The research undertaken is directed towards methods of safety assessment relating closely to current world trends, aiming to ensure safety of water supply and use. The paper pays special attention to water consumer safety. Safety levels were assumed on the basis of failure intensity, exposure of water consumers and a number of undesirable event groups. Individual values of the immediate risk index were presented and three categories were distinguished as permissible, tolerable, or unacceptable risk categories, according to presumed action. The risk index can characterize the safety of the functioning of technical systems. The risk index definition is considered as the product of threat ranking. The paper contains the original proposal for a new method of risk analysis and assessment.

Using data on work accidents and annual mining statistics, the paper studies work-related accidents in the Spanish energetic mining sector in 1999–2008. The following 3 parameters are considered: age, experience and size of the mine (in number of workers) where the accident took place. The main objective of this paper is to show the relationship between different accident indicators: risk index (as an expression of the incidence), average duration index for the age and size of the mine variables (as a measure of the seriousness of an accident), and the gravity index for the various sizes of mines (which measures the seriousness of an accident, too). The conclusions of this study could be useful to develop suitable prevention policies that would contribute towards a decrease in work-related accidents in the Spanish energetic mining industry.
