Abstract
Description
본 발명은 원유 생산용 해양 구조물을 육상 건조 후 운송용 배로 싣는 푸싱 및 풀링 그립퍼 잭 시스템을 이용한 로드 아웃 방법에 관한 것이다.The present invention relates to a load out method using a pushing and pulling gripper jack system for loading a marine structure for crude oil production into a ship for transportation after land drying.
기존에는 대형 중량물의 경우에는 푸싱 그립퍼 잭 시스템(Pushing Gripper Jack System)과 풀링 시스템(Pulling System)인 윈치(Winch)를 이용하여 로드 아웃을 수행하였으나, 푸싱 그립퍼 잭 시스템의 용량 부족으로 인하여 작업에 어려움이 있었다.Conventionally, heavy loads were loaded out using the Pushing Gripper Jack System and the Winch, the Pulling System. However, due to the lack of capacity of the Pushing Gripper Jack System, it is difficult to work. There was this.
도1 및 도2에는 종래의 해양 구조물을 운송용 배에 싣는 로드 아웃 방법이 정면도와 평면도로 도시되고 있다.1 and 2 show a load out method for loading a conventional marine structure on a ship for transportation in a front view and a plan view.
운송용 배(1)는 수면 위에 띄워 있고 해양 구조물(2)은 육상의 스키드 비임(3)과 바아지(4)의 스키드 비임(5)위로 이동하게 된다.The transport vessel 1 floats on the water surface and the marine structure 2 is moved over the skid beams 3 of the land and the skid beams 5 of the bars 4.
해양 구조물(2)은 후방에 위치한 푸싱 그립퍼 잭 시스템(6)에 의해서 밀쳐지고 전방에 위치한 풀링 윈치 시스템(7)에 의해서 당겨지며 배(1)위로 이동된다.The offshore structure 2 is pushed by the pushing gripper jack system 6 located at the rear and pulled by the pulling winch system 7 located at the front and moved onto the ship 1.
푸싱 그립퍼 잭 시스템(6)은 커넥션 헤드 블록을 해양 구조물(2)의 스키드 슈우(9)에 연결한 후 푸싱작업을 행한다.The pushing gripper jack system 6 connects the connection head block to the skid shoe 9 of the offshore structure 2 and then pushes it.
풀링 윈치 시스템(7)은 도1에 확대되어 도시되듯이 스키드 슈우(9)에 설치된 러그(10)와 바아지(4)의 끝단에 고정된 시브 블록(Sheave Block)(11)사이에 윈치와이어(12)를 8차로 연결하여 도2에 도시된 안벽부에 설치된 윈치(13)로 풀링작업을 행한다.The pulling winch system 7 is a winch wire between the lug 10 installed on the skid shoe 9 and a sheave block 11 fixed to the end of the bar 4, as shown enlarged in FIG. (12) is connected in eighth order, and the pulling operation is performed by the winch 13 provided in the inner wall part shown in FIG.
로드 아웃 작업은 윈치(13)에 텐션을 가하고 푸싱 그립퍼 잭에 동일한 압력을 가하여 해상 구조물(1)을 원 스트로크 푸싱한다.The load out operation tensions the winch 13 and applies the same pressure to the pushing gripper jack to one stroke push the offshore structure 1.
해상 구조물(1)의 전진 거리 만큼 푸싱 그립퍼 잭을 전진시키고 윈치는 안벽부의 드럼을 회전시켜 일정한 텐션을 유지하고 상기 작업을 반복 실행한다.The pushing gripper jack is advanced by the forward distance of the offshore structure 1 and the winch rotates the drum of the inner wall to maintain a constant tension and repeats the above operation.
상기와 같은 기존의 로드 아웃 방법은 윈치 시스템의 와이어 작업 시간, 시브 블록과 새클(Shackles)의 체결 시간 과다 및 치구 물량 과다로 인해 임대 사용에 따른 비용이 소요된다.Existing load out methods as described above are expensive due to lease use due to the wire working time of the winch system, the excessive time for fastening the sieve block and the shackles, and the excessive amount of jig.
본 발명의 목적은 상기와 같은 문제점을 해결하기 위하여 푸싱 및 풀링 그립퍼 잭 시스템을 이용한 로드 아웃 방법을 제공하고자 하는 것이다.An object of the present invention is to provide a load out method using a pushing and pulling gripper jack system in order to solve the above problems.
본 발명의 로드 아웃 방법은 풀링 그립퍼 잭에 80% 정도의 텐션을 가하고, 다음에 푸싱 그립퍼 잭에 압력을 가하여 동일하게 대형 구조물을 원 스트로크 푸싱하며, 대형 구조물의 전진 거리 만큼 양쪽 그리퍼 잭을 전진시켜 다시 그립핑하고 상기 작업을 반복 실행하여 이루어진다.The load-out method of the present invention applies a tension of about 80% to the pulling gripper jack, and then applies pressure to the pushing gripper jack to one-stroke pushing the large structure in the same way, and advances both gripper jacks by the forward distance of the large structure. This is done by gripping again and repeating the operation.
