Abstract
Seafarers' knowledge and skill have been passed down from people to people on board ships. But recently, it is becoming more and more difficult to pass down the skills and experiments of seafarer to the next generation. Especially, it is very difficult to pass down what we call intuition or tacit knowledge, which is one of the seafarers' knowledge that is acquired only through various experiences on board ship. In order to pass down and maintain those skills and knowledge as much as possible to the younger generations, we propose here the system to collect, sort out and compile database where the skilled seafarers can add and accumulate their own tacit knowledge while working on board. Thereby younger seafarers can have opportunities to learn those skills with their predecessor's actual experiences, the further engineering backgrounds and other applications. In this research, we focus on engine part as our subject.
