The Japanese classification society NK published a 42 page booklet titled “Guidelines for the Prevention of Human Error Aboard Ships”, with the sub heading “Through the Ergonomic Design of Marine Machinery Systems.” According to the guidelines, man-made causes are said to account for 80 per cent of all marine accidents. The guidelines stress the importance of standardization in operating, control, methods, indicators, labeling and color coding to reduce confusion, avoiding the situation when crews familiar with a procedure on one ship are faced with opposites in procedure on another ship. To this end ergonomic design plays an important part so that operation of equipment is easy to understand and logical (even though logic differs by culture). A chapter covers design considerations and recommendations and there is an interesting section titled countermeasures giving advice on risk assessment and the best course of action to prevent (re-) occurrence. The publication includes a number of detailed reports of marine accidents and how to prevent their recurrence.
