heal.abstract	Στην παρούσα διπλωματική γίνεται μια ανάλυση ρίσκου σε ατυχήματα πλοίων που προέρχονται από λάθη επιθεωρητών. Η ανάλυση του ρίσκου έγινε με την μέθοδο bow tie η οποία επιλέχθηκε με βάση την ευχρηστία και την ευκολία αναπαράστασης του ρίσκου και των διαφόρων κινδύνων σε ένα ατύχημα. Έχει παραχθεί μια μεθοδολογία αναπαράστασης των ατυχημάτων αυτών με διαγράμματα bow tie καθώς και έχουν παραχθεί διάφορα σενάρια πιθανών ατυχημάτων που προέρχονται από προβληματικές επιθεωρήσεις.	el
heal.abstract	Inspections are a great part of vessels' lifetime. They define different problems and areas that need to be taken under consideration for orderly functioning of marine operations. It is evident throughout history that many marine accidents occurred because of mistakes done from inspectors and surveyors. Due to their highly demanding duties, inspectors often fall into errors that can lead to major hazards. This problem underlines the necessity of a proper risk analysis of these types of accidents that can clearly show the factors that contribute to accidents and their connection with inspections. Risk analysis has been used for identification of hazards and their risk in many researches for many decades and it is a crucial element in every industrial environment. This research focuses on the aspects of risk management and analysis and tries to present a useful model that can be used for accidents that derived from inspection mistakes. This model has to be generic in order to be able to represent the majority of the accidents this research focuses on. A statistical analysis was held in fifty accidents in order to properly show the diversity of accidents that fall into the category of inspection mistakes and to underline the different type of consequences that these accidents have. Also the differentiation between various types of ships is statistically defined for the purpose of the research. All the results are presented in various graphs that give much information about the accidents. Bow tie analysis is a fairly new concept in risk assessment that can describe the relationships of different parameters, such as causes, hazards and consequences and to underline the occurrence of unwanted incidents. This paper presents how bow tie diagrams can be used for risk analysis in marine accidents derived from inspection errors as well as standing alone as a detailed risk analysis. A large number of bow tie diagrams were generated in order to represent the major type of accidents that are inspection errors in different types of ships such as Container ships, General cargo ships, Passenger ships etc. Also these diagrams were validated and tested in ten real accidents where their importance and accuracy is clearly demonstrated. Finally, twelve generic scenarios were created that show how easily different incidents and scenarios can be displayed and generated using this methodology.	en
