MODEL OF CIRCULAR RISK ASSESSMENT OF SHIP’S MOORING OPERATION USING INFORMATION TECHNOLOGY
Abstract
Introduction. Mooring operations are a critical link in the chain of technological operations of modern vessels, as their efficiency affects their safety, the safety of port workers and the environment. Failure to take into account the risks during mooring can lead to significant emergencies, equipment damage and delays in transportation processes. The proposed model of circular risk assessment allows for a more systematic approach to risk management and helps to solve the problems associated with underestimating certain threats during mooring, which is often the case in traditional approaches. Objective. The main goal is the study of a comprehensive risk assessment model (which takes into account other participants in the operation and was proposed earlier) during the vessel mooring operation. Such a model can have different risk calculation algorithms, in particular, a typical calculation (based on the classical approach) and a calculation using fuzzy sets. The results. A model of round-robin assessment of the risks of a vessel mooring operation using Internet technologies has been developed. A comparative analysis of two possible risk assessment algorithms was carried out, for one of them a program, which uses Excel capabilities was developed, which allows us to calculate automatically the result of such an assessment when input data is changed. Conclusions. The obtained results of the study make it possible to conclude that the algorithm based on fuzzy sets is more accurate compared to the usual calculation method (because the risk parameters are inherently fuzzy), but it narrows the range of possible solutions. Both algorithms are highly dependent on the correct formalization of the original data. In both cases, further research is needed. In any case, the circular risk assessment model will simplify the risk management process, partially relieve crew members and increase shipping safety due to more accurate results and almost complete elimination of the human element from the risk assessment process.
