부산항은 "한진 해운 파산"과 같은 불확실한 해운 상황에도 불구하고 2017년도 2,000만 TEU 이상 물동량을 처리하였다. 선박 생산성 또한 높은 수준으로 세계에서 가장 바쁜 터미널 6위를 달성하였다. 우리는 이러한 높은 수준을 유지하기 위하여 고객에게 생산성뿐만 아니라 고품질의 안전성 또한 제공하여야한다. 부산항 'A' 터미널에서 발생한 지난 3년간의 사고 데이터를 분석하여 어떤 장비가 가장 많이 사고를 발생하였고 어떤 위험점이 가장 높은지를 위험성 평가기법으로 알아보고, 이러한 사고를 미연에 방지하기 위한 방안을 보우타이 기법을 활용하여 제시하고자 한다. 실증자료를 분석한 결과 터미널 내의 이동장비 중 야드 트랙터의 충돌사고가 가장 높은 것으로 나타났다. 안전한 부산항을 만들기 위하여 우리는 가장 먼저 야드 트랙터의 충돌사고 예방법 (Control measure)과 사고 발생 시 대처방안 (Recovery measure)을 철저히 준비하여 사고를 미연에 방지하여야 할 것이다. 본 연구의 결과는 관련 실무에 다양한 시사점을 제공하였다.

It is time to study safety improvement on container terminals to maintain a high-quality service to customers' productivity and safety. The data analyzed was of the past 3 years accidents data from a container terminal in the Busan port. I especially tried to found out the equipment that had the highest number of accidents and what the main causes were. This study suggests the top hazards identified in the container terminal using risk assessment, Moreover, it seeks control measurements to prevent hazards by bowtie methodology.

A HAZID is a brainstorming workshop to identify hazards in an early phase of a project. It should be flexible to capture all probable accidents allowing experienced participants to exploit their expertise and experiences. A bowtie analysis is a graphical representation of major accident hazards elaborating safety measures i.e. barriers. The result of these workshops should be documented in an organized manner to share as good as possible details of the discussion through the lifetime of the project. Currently results are documented using a three-step representation of an accident; causes, top event and consequences, which cannot capture correctly sequence of events leading to various accidents and roles of barrier between two events. Another problem is that barriers would be shown repeatedly leading to a misunderstanding that there are an enough number of safety measures. A new bowtie analysis method is proposed to describe an accident in multiple steps showing relations among causes or consequences. With causes and consequences shown in a format of a tree, the frequencies of having the top event (Fault tree analysis) and various consequences (Event tree analysis) are evaluated automatically based on the frequency of initiating causes and the probabilities of failure of barriers. It will provide a good description of the accident scenario and help the risk to be assessed transparently.
