Various troubles occurring in the vessels during service may cause material or monetary loss for operations side and credibility loss for cargo owners. As an issue of ship design, countermeasures to prevent troubles and to reduce those trouble and losses can lead to value creation for customers' satisfaction. Also, in consideration of the current circumstances of risks of exchange rate fluctuations and soaring ship's material, preventing on-board trouble is one of important issues for shipping industry of Japan to maintain international competitiveness.
In this study, we first create the trouble database using about 200 on-board trouble data from 15 vessels owned by a shipping company in Japan from 2007 till the first half of 2011. Following practicable examples are analyzed and presented: analytical results of on-board troubles caused by human factors through the trend analysis and factor analysis, and machine trouble analysis based on the FMEA (Failure Mode Effects Analysis) and 4M5E analysis for severe accidents.
