캐미컬 선박 사고처리시의 주요 차이점

- 케미컬 화물에 대한 무지와 당국과 지역주민의 막연한 불안

언론의 침소봉대(針小棒大) 보도- 언론의 침소봉대(針小棒大) 보도

- 당국의 입항거부와 과도한 요구/제한과 작업지연

- 유류오염에 비해 사실상 피해가 미미함에도 불구하고 어민을

포함한 지역주민의 막연한 클레임 제기 문제점

- 동일한 사고 사례가 적어 구조비/잔해 제거비 산정의 어려움

Problem of Delay(延期的理由)

Basically, adverse weather condition including several typhoons.(天气问题有很多台风来)

1. Due to the heavy damage, found air refloating infeasible.(因为损伤严重不可以空气浮船)(因为损伤严重不可以空气浮船)

2. Initially to make underwater cutting to 3 pieces - but take approx. 2 months. (水中切断, 但是长期工作)

3. In order to shorten the duration, arrange demolishing Vessel - but High possibility of oil pollution result of the unintentional additional crack damage to the bunker tanks and also remarkable deterioration of the casualty after trial of air refloating. (用抓斗船可以但是考虑污染问题的可能性)

4. Change of method to underwater cutting by divers and lifting up the cut-off 3 pieces of the casualty by mobilizing floating cranes. (为了污染防止改计划-用潜水员和起重船)

캐미컬 선박사고 특성 요약

1. 타 선박에 비하여 비교적 사고 사례가 적다.

2. 주로 소형선이지만, 사고 시에 거대 클레임으로 발전가능성 높다.

3 소형선이고 단기 항해의 바쁜 일정 – 해기사의 비호감 경향3. 소형선이고, 단기 항해의 바쁜 일정 해기사의 비호감 경향.

4. 일반적으로 캐미컬 선박을 원자 폭탄으로 초 과대비교 경향이 있어, 안전

항구로 진입의 장벽이 매우 높다 – 언론사의 과대 광고.

5. 비중 1.8인 황산과 같은 화물의 경우에는 비중이 벽돌과 유사하여, 항해 중

에 유동수 영향으로 선체에 상당한 충격을 줄 수 있어 선체에 육안식별이

어려운 미세 크랙 발생 – 수소가스에 폭발/침몰 초래한다.어려운 미세 크랙 발생 수소가스에 폭발/침몰 초래한다.

6. 캐미컬 선박사고 처리에 대한 실질적인 전문가 사실상 없다. 정부 및 항만

담당의 설득이 쉽지 않고, 전문가의 의견수렴 할 결정권자 부재.

7. 구조업자나 잔해 처리 관련하여 구조비/처리비 산정이 어렵고, 제한된 업

체와 계약체결로 인해 가격이 상대적으로 매우 높다.

캐미컬 선박의 추가적인 위험관리 방안

황산과 같은 화물을 주로 선적하는 선박인 경우, 주기적인 화물창의

미세크랙 증후 사전 확인 및 SYSTEM 필요.

사고예방

- 선급과의 협력관계 요망

사고 시에 즉시 대응 가능한 이론과 실무를 겸비한 전문가 필요

- 선박,

보험/보상처리

사고처리

- 보험/보상처리,

- 캐미컬 화물특성,

- 구조/제거작업,

- 당국/어민 설득/협상 등

다양한 전문인력 활용방안과 결정권자 필요.
