해양사고의 대부분은 해상교통량이 많은 연안해역과 해수욕장, 방파제 등 많은 사람들이 찾는 연안지역에서 발생한다. 최근 해양레포츠의 활성화로 연안에서의 안전사고위험은 더욱 증가하고 있다. 그러나 연안의 안전사고에 대한 대책이 안전사고 증가속도에 적절하게 대응하지 못하고 육지와 바다를 연계한 안전관리가 체계적이지 못하다. 최근 5년 동안 발생했던 안전사고를 분석하여 사고발생을 최소화할 수 있는 안전관리 대책방안에 대하여 연구하였다. 연안의 안전사고는 육지와 바다가 접촉되는 연안지역에서 발생하기 때문에 종합적인 안전대책이 필요하며, 종합적인 안전망 구축을 위해서 제도상 법률상으로 주무기관이 일원화되어야 한다. 또한 사고발생시 신속하게 인명과 재산을 구조할 수 있는 사고대응 체제가 체계적이고 효율적으로 작동되도록 구축되어야 한다.
One of the most important missons that are imposed on merchant ship at sea is to accomplish the safe transportation of cargo loaded. Recently, a study on the seakeeping performance has been carried out on the development of evaluation system related to the synthetic safety of a ship at sea. The seakeeping performance is the ship's ability sailing at, and executing its misson against adverse environmental factors successfully and safely. Until now, however, there has not been any method of quantitative evaluation on the dynamic safety of the ship's cargo loaded. In this regards, this paper has introduced the evaluation method of dynamic safety of the ship's cargo. In order to evaluate the dynamic safety of cargo, the vertical and lateral acceleration which causes the collapse, racking and local structure failure of cargo was adopted as the evaluation factors in the ship's motions. The response amplitude of ship's motions in regular waves is manipulated by NSM (New Strip Method) on a given 2,700 TEU full container vessel under the wind forces of 7, 8 and 9 Beaufort scale. Each response of ship's motions induced by NSM was applied to short-crested irregular waves for stochastic process on evaluation factors and then vertical and lateral acceleration of each cargo was compared with significant amplitude of each acceleration. A representative dangerous factor was determined by comparing permissible values of stacking and racking forces occurred typically to the vertical and transverse directions with the container strength required on ISO 1496 at the positions of forecastle, poop and ship's midship respectively. Through the occurrence probability of the determined factor by Rayleigh's probability density function, the dangerousness which limits loads on container's side wall as an evaluation was applied in judging of the danger of the ship's cargo loaded.
