해저케이블 건설공사에 종사하는 산업잠수사 안전작업에 관한 연구

Abstract

현재 우리나라 도서간 설치된 케이블의 길이는 약 1,011Km 이며, 해저케이블건설공사는 수심 0~3,000m까지 설치하며 나날이 기술이 발전하고 있다. 하지만 천해부 구간(0~30m)은 산업잠수사들이 해저케이블 설치 및 보호공을 실시하고 있다. 산업잠수사들은 수중작업이라는 특수성이 있어 사소한 부주의에도 대형사고로 이어질 수 있다.국내 해저케이블건설공사에 종사하는 산업잠수사들은 프리랜서 잠수사들이 대부분이며, 회사에 소속되어 있는 잠수업체들도 대부분이 영세 업체이다. 해저케이블건설공사만 종사하는 산업잠수사의 인원은 정확한 인원을 산출하기는 어려우며, 해저케이블건설공사를 반복적으로 수행한 잠수사는 약 50명 정도가 현장에서 일한 것으로 추정된다.해저케이블 건설공사는 간간히 나오는 공사로써 대부분의 산업잠수사들은 해저케이블건설공사가 없을 때는 항만건설, 수중용접 등 타 공사에 투입되어 일하고 있는 실정이다. 수중에서 일하는 것은 타 공사현장과 동일하지만 해저케이블건설공사의 특수성을 감안하여 산업잠수사의 위험요인 발굴, 교육 등이 없는 것인 현실이다.또한, 해저케이블건설공사는 육지에서 먼 바다로 케이블을 설치하는 공사로써 타 공사와 다르게 연안에서 점점 먼 바다로 나가는, 즉 작업의 범위가 길어지는 특수성이 있다.이 특수성을 감안하여 해저케이블건설공사에 종사하는 산업잠수사들의 재해를 예방하고 안전작업을 위한 목적으로 연구를 실시하여 산업잠수사들이 특수성을 이해하고 안전한 작업을 할 수 있는 방안을 제시하고자 한다.

The submarine cable construction works at 0 ~ 3,000m (water depth) and the technology are developing from day to day. Industrial engineer dives are installing submarine cable and carrying out protection works in the coastal section (0 ~ 30m). Industrial engineer dives have a special feature of underwater work, which can lead to major accidents even with minor carelessness. Industrial engineer dives engaged in domestic submarine cable construction are mostly freelancer divers. It is difficult to calculate the exact number of Industrial engineer dives personnel engaged only in submarine cable construction. It is estimated that about 50 divers have repeatedly carried out submarine cable construction work on site. The submarine cable construction is a temporary construction. Most Industrial engineer dives are engaged in other construction projects such as harbor construction and underwater welding when there is no submarine cable construction work. Working underwater is the same as other constructions; however, considering the special characteristics of submarine cable construction, it is a reality that industrial diver has no risk factors and education. In order to prevent the disasters of Industrial engineer dives engaged in submarine cable construction and to carry out research for the purpose of safety work in consideration of specificity, it is proposed that Industrial engineer dives understand the specificity and work safely. For this purpose, data were collected through previous studies of related papers and literature survey of domestic standards. It was also found through interviews with the supervisors that the special characteristics of underwater cable construction were wind speed, tidal current, and visibility, digging and working method. Based on this, I interviewed industrial surveys and questionnaires to find out the current status of the work and to draw up problems in the work environment. In the actual field of industrial submersibles engaged in submarine cable construction, the environment was a very important factor, but there was no precise standard and there were not many devices to measure. Most of the environmental factors are based on the surveillance warning or the experience of the field supervisor is an important factor. However, the situation prior to the storm surge may well be a dangerous environmental factor for Industrial engineer dives engaged in submarine cable construction, and various environmental hurdles can be combined. Based on the analysis results, a checklist was prepared before the diving operation. Industrial engineer dives engaged in the submarine cable construction project will use the pre-work checklist to contribute to the prevention of safety accidents.
