SR233「船舶の高度モニタリングの基礎研究」 要約
Ship Research Panel 233 「Study on Advanced Monitoring of Ship」
How to manage the economical performance and the hull safety on navigation through the ship's service life - this is the recent key interest for shipowners, shipoperators, shipbuilders and other maritime party concerned. The management will need technically the information of the ship's present condition on navigation such as speed, motions and ship strength under the sea environment for judging and predicting the ship's behavior. The monitoring is one of the useful way for that.
This research is the 3-year basic study (1996FY to 1998FY) on the advanced method to monitor ship responses together with the encountered wave conditions.
Differnt from the conventional full scale measurement, the advanced monitoring system may be requested 'simple sensing system, quick data analysis and long-time support' and 'proper communication between onboard and land-control center with digital data basis'
The study was carried out on the following items;
1. Research and development of the sensors such as fiber optic sensor for strain monitoring, sacrificial specimen for fatigue damage monitoring, wave measuring device deduced from ship motions itself for wave monitoring, and so on.
2. Research and development of the onboard data analysis system for the ship's performance and response data obtained at proper intervals (five minutes or one hour) and also the estimation system in land for the analized data.
3. Study and proposition of the concept design on the advanced monitoring system based on 1&2 research and development.
4. Almost one-year field test by a container ship and a bulk carrier with the propsed monitoring system fully or partialy including trial of digital data communication via satellite.
Through the study, this research can give the skeleton of the advanced monitoring system (SR233 AMS) with the necessary technology for sensing and analysis, which will be expected to apply for the shipping fields in near future.
