통상적으로, 선박의 후미에는 추진용 프로펠러가 장착되어 있으며, 상기 프로펠러의 정역방향으로 회전하게 됨에 따라 선박이 전진 혹은 후진을 하게 된다. 이와 같이 프로펠러가 회전할 때 그 주위에는 와류가 형성되고 주위의 이물질들이 쉽게 프로펠러 중심으로 흡수되면서 후방으로 이동된다. 이때 수중에 떠있는 이물질은 프로펠러에 감겨 치명적인 영향을 준다. 즉, 바다에 버려진 그물 및 각종 로프(이하 '로프'라 함)가 프로펠러에 유입될 경우에는 상기 이물질은 프로펠러와 샤프트에 감기게 되면서 더 이상 샤프트가 회전하지 못하게 되거나, 선미 베어링을 파손하게 되어 심대한 선박손상을 초래하게 된다. 이와 같이 프로펠러 및 샤프트에 로프가 감기면 종래에는 선원 등이 잠수하여 로프를 해체하고 있으나, 이는 상당히 위험한 작업으로서 인명사고의 위험을 가지고 있다. 또한 잠수할 수 있는 능력을 가진 선원이 없고 원양어업중인 어선의 경우에는 조난사고에서 벗어날 수 없는 결과를 초래한다.Typically, a propeller for propulsion is mounted to the rear of the ship, and the ship moves forward or backward as it rotates in the forward and reverse directions of the propeller. As such, when the propeller rotates, a vortex is formed around it, and foreign matters around it are easily absorbed into the center of the propeller and moved backward. At this time, foreign matter floating in the water is wound on the propeller has a fatal effect. In other words, when the net and various ropes (hereinafter referred to as 'ropes') abandoned in the sea are introduced into the propeller, the foreign matter is wound on the propeller and the shaft, and the shaft no longer rotates, or the stern bearing is damaged. It will cause ship damage. As such, when the rope is wound around the propeller and the shaft, sailors or the like are conventionally dismantled to dismantle the rope. In addition, fishing vessels with no crew capable of diving and ocean-going fishing will not be able to escape the distress accident.
