Description

선박 밸러스트 시스템Ship ballast system
본 발명은 선박 밸러스트 시스템에 관한 것으로서, 더욱 상세하게는 선박의 흘수와 트림을 조정하기 위한 선박 밸러스트 시스템에 관한 것이다.The present invention relates to a ship ballast system, and more particularly to a ship ballast system for adjusting the draft and trim of the ship.
일반적으로, 화물선에 선적된 화물이 많지 않을 경우 추진기 및 방향타의 효율적인 작동과 균형 유지 및 안정성을 위해 밸러스트 탱크(Ballast Tank)에 해수를 담은 상태로 운항을 한다. 이때 밸러스트 탱크 내에 적재되는 물을 밸러스트 수(Ballast Water)라 부른다.In general, when there are not a lot of cargo loaded on the cargo ship, the ballast tank is operated with seawater for efficient operation, balance and stability of propeller and rudder. At this time, the water loaded in the ballast tank is called ballast water.
이러한 밸러스트 수는 선박의 흘수(吃水)와 트림(Trim: 배의 앞뒤 경사)을 조정하기 위하여 적재하는 중량물로서 선박의 균형유지와 안정성을 높이는 기능을 하게 되며, 화물을 충분히 적재하지 않은 경우에 추진기와 방향타가 물속에서 효과적으로 작동되게 하는 보조기능을 수행하게 된다.This ballast water is a heavy load to adjust the ship's draft and trim, and it functions to maintain the balance and stability of the ship. And the rudder serve as an aid to effectively operate in water.
상술한 밸러스트 수는 선박이 철재로 건조되기 시작한 1870년대 후반부터 사용되고 있으며, 선박에 따라 밸러스트 수를 적재하지 않고, 광석이나 모래 등을 밸러스트로 사용하는 경우도 있으나, 오늘날에는 해수나 담수를 밸러스트로 사용하는 것이 보편화되어 있다.The ballast water described above has been used since the late 1870s when ships began to be built of steel, and some ships use ore or sand as ballasts without loading ballast water, but today seawater or fresh water is used as ballasts. Use is commonplace.
그러나, 이러한 밸러스트 수는 특정 해역의 생물 또는 병원균 등을 다른 해역으로 전파시키는 매체가 되는 문제점이 있다. 즉, 밸러스트 탱크에 채워지는 밸러스트 수로 대부분 해수가 사용되는데, 밸러스트 수에는 각종 해양 생물 및 병원균 등이 포함될 수 있으며, 이러한 밸러스트 수의 유입과 유출이 서로 다른 지역에서 이루어지게 되므로, 밸러스트 수의 유입시 함께 유입된 특정 해역의 해양 생물 또는 병원균이 다른 해역으로 유출됨에 따라 환경과 생태계를 교란시키는 부작용을 유발하게 되는 문제점이 있다.However, such ballast water has a problem of being a medium for propagating organisms or pathogens in a specific sea area to other sea areas. That is, most of the seawater is used as the ballast water filled in the ballast tank, and the ballast water may include various marine organisms and pathogens, and since the inflow and outflow of the ballast water are made in different regions, the inflow of the ballast water As marine organisms or pathogens in a specific seawater flow in to other seawater, there is a problem that causes side effects that disturb the environment and the ecosystem.
이에 미국에서는 1996년 국가 침입종 법률을 제정하여 외래종을 침입자로 규정, 밸러스트 수에 대한 관리와 통제를 의무화하였으며, 호주에서는 검역법을 개정하여 밸러스트 수를 검역 대상이 되는 수입화물로 규정하고 직접검역을 실시하고 있다.In 1996, the United States enacted the National Invasive Species Act in 1996, mandating alien species as intruders and mandating the management and control of ballast water. We carry out.
또한, 국제해사기구(International Maritime Organization)에서는 2004년 2월 국제협약을 체결하여 2009년부터 순차적으로 밸러스트 수 살균처리장치를 선박에 탑재하도록 하여 위반시 해당 선박의 입항을 전면 금지하도록 하고 있다. 즉, IMO(국제해양기구)에서 밸러스트 수의 유출시 밸러스트 수를 소독하거나 필터링(filtering)하여 밸러스트 수에 포함된 해양 생물이나 병원균을 처리하는 과정을 거치도록 했다.In addition, the International Maritime Organization signed an international agreement in February 2004, and since 2009, the ballast water disinfection treatment device should be installed on a ship in order to prohibit entry of the ship in case of violation. In other words, the IMO (International Maritime Organization) disinfects or filters the ballast water when the ballast water is leaked to process marine organisms or pathogens contained in the ballast water.
그러나, 상술한 바와 같이 밸러스트 수를 처리하는 밸러스트 수 처리 설비는 상당히 고가이고, 선박 내에 설치 시 상당히 넓은 설치 공간을 필요로 하므로, 경제적인 선박 설계를 행함에 있어 장애 요소가 되는 문제점이 있다.However, as described above, the ballast water treatment facility for treating the ballast water is quite expensive, and requires a large installation space when installed in the ship, there is a problem that becomes an obstacle in performing an economic ship design.
