VDR 성능 향상을 위한 항해위험도 평가 기술의 적용에 관한 연구

Abstract

For the purpose of technological analysis in the marine accidents and their prevention, IMO have made it obligatory to load VDR which is similar to the Black Box of aircraft.

However, there were difficulties for judging because of amendment of each record after accidents and changed to statement. In case of stranding and sinking accidents, which are 20% of marine accidents, it is difficult to get the necessary records for marine accidents judgement, what is more, almost impossible to get when they happened on the ocean.

In order to analyse the cause of stranding and sinking accidents, it is necessary to use the seakeeping performance evaluation technology which is used in naval architecture.

Therefore, we are going to evaluate the marine accidents based on VDR recording data using the application of navigation dangerousness evaluation technology for improvement of VDR performance.

We have carried out the analysis of the cause of ship stranding and sinking accident using vertical acceleration data. Besides existing IMO recommended record data, we suggest the vertical acceleration as additional records of VDR.
