This paper presents research results on the causes and effects of human errors in relation to typical ship design factors, such as noise, vibrations and ship motions. Following a review of the relevant literature, aimed to the identification and quantification of pertinent parameters and effects, a detailed questionnaire has been developed and answered by seafarers. The questionnaire results are presented in the form of quantitative risk models, using Bayesian networks with applications on two safety-critical ships, namely containerships and tankers. Finally, we present the generic collision and grounding causation probabilities for both ship types. The results are found to be in good agreement with current literature. Knowledge of the ship design factor effects on the human performance in quantitative form would be useful in the ship design and the development of new safety rules and regulations.
