Abstract

The Nairobi International Convention on the Removal of Wrecks(The Nairobi Convection, 2007) consequently will enter into force on April 2015, 1 year after Denmark became the 10th country to ratify it on April 2014. As wrecks are major risks for safety and pollution, the Nairobi Convection will be greater harmonisation of the laws on wreck removal internationally to remove wrecks quickly and effectively and to provide protection against such risks.
As of September 2014, over 2,000 sunken vessels are found on the territorial sea of Korea. Sunken vessels should be had harmful impacts on marine environment because of oils and chemicals in the sunken vessels. Moreover, temporary or continuous spill of remaining harmful substances such as crude oil and chemicals occur a secondary pollution in the ocean and are likely to become factors causing marine accidents in major port or sea route.
The government have been promoting sunken vessels management business to grasp the current situation of sunken vessels. Furthermore, they developed risk assessment which can evaluate potential risk quantitatively for sunken vessels in order to establish national management system for sunken vessels.
In this study, analyzed marine accidents in Korea and overlooked sunken vessel management system with database program and sunken vessels distribution chart. In addition, as comparison sunken vessel management database and risk assessment factor, draw the limitation of the present risk assessment. Marks of present risk assessment changed greatly depending on quantity of remaining fuel oils, and the list of remaining fuel oils omitted in status report of sunken vessels. Therefore, the aim of the study is to estimate and develop model for quantity of remaining fuel oils and verify the estimation remaining fuel throughout operating vessels at present.
To accomplish the purpose of study, applied this verified estimation model to current risk assessment and recommend guideline for an accurate sunken vessels risk assessment and various improvement method of sunken vessels management system.
