본 발명은 대상물 상에서 자유낙하 구명정이 진수하는 충격을 완화하는 장치에 있어서: 상기 대상물에 상하운동 가능하게 설치되고, 구명정(10)을 분리 가능하게 탑재하는 대빗(20); 상기 대상물과 대빗(20) 사이에 직선형 전동기를 구비하고, 중력과 반대되는 인력을 작용하는 감속수단(30); 및 상기 대빗(20)의 감속도를 설정된 알고리즘으로 제어하는 제어기(40);를 포함하여 이루어지는 것을 특징으로 한다. 이에 따라, 해양 구조물에 설치된 자유낙하식 구명정의 진수 과정에서 낙하 방향의 반대 방향의 힘을 발생시켜 낙하 속도를 줄여줌으로서 입수 시 탈출자에게 전달되는 충격량을 최소화하는 효과가 있다.

    The present invention relates to a launching impact relieving apparatus of a free fall lifeboat which is for relieving an impact created when a free fall lifeboat is launched on an object, comprising: a davit (20) installed on an object so as to be vertically movable, and detachably mounting the lifeboat (10); a deceleration means (30) having a linear motor between the object and the davit (20) and acting as an attraction force opposite to gravity; and a controller (40) controlling the speed of deceleration of the davit (20) by a set algorithm. Accordingly, the free fall lifeboat installed in an offshore structure generates a force in a direction opposite to a falling direction during launching, thereby reducing a falling speed and minimizing the amount of impact transmitted to an escapee when going into water.
