초록

선박을 통한 세계교역 증가에 따라 침입외래종(Invasive Alien Species, IAS)로 인한 해양생태계파괴 및 사회경제적 피해가 지속적으로 증가하고 있다. 특히 선체표면과 틈새구역(Niche Area)에 부착된 해양생물의 이동은 외래종침입 문제뿐만 아니라 선박의 마찰저항을 증가시켜 운항효율감소 및 온실가스배출 증가를 유발한다. 국제해사기구(IMO)는 최근 선체부착생물 통제 및 관리에 대한 지침 개정작업에 착수하였고 뉴질랜드와 미국 캘리포니아는 이미 자국법으로 선체부착생물 관리를 규제하고 있다. 본 논문에서는 국내에 입항하는 국제운항선 5척을 대상으로 선체부착생물 관리현황과 생물부착현황을 조사하였고, 생물부착종과 피도(Coverage)를 분석하여 생물부착단계 등급(Level of Fouling, LoF rank)을 평가하였다. 모든 선박에서 대형부착생물(Macrofouling)이 관찰되었고 특히 선수 스러스터(Bow thruster), 빌지킬(Bilge keels) 및 해수 흡입구 격자(Sea-chest gratings)와 같은 틈새구역의 대형개체(Macro organisms) 부착이 심각한 수준으로 나타났다. 본 연구에서는 국내 선체부착생물 관리방안을 제시하고, 실선대상 생물부착단계등급 적용 및 검사(Inspection) 방법 개선방안을 제안하고자 하였다.

With the increase in world trade through ships, the destruction of the marine ecosystem and socioeconomic damage due to invasive alien species (IAS) are continuously increasing. In particular, marine organisms attached on the hull surface and niche area increase the friction resistance of ships as well as the invasion of non-indigenous species, and causes a decrease in operational efficiency and an increase in GHG (Green House Gas) emissions. The International Maritime Organization (IMO) has recently begun revising guidelines for the control and management of ship's biofouling, and New Zealand and California in the United States are already regulating biofouling management under their own laws. This study investigated the management status of the submerged surface of ships and marine organisms attachments on five international ships entering South Korea, and analyzed species group and coverage (%) of biofouling communities to evaluate the LoF (Level of Fouling) rank. Macroflouling was observed on all ships surveyed, and specially, the adhesion of macro organisms in niche areas such as bow thruster, bilge keels and sea-chest gratings appeared to be at a serious level. This study proposed the management direction our country should take with regard to ship's biofouling and the improvement measures for evaluation of LoF rank and inspection methods of hull and niche ares.
