슈퍼 블록 스키딩에 의한 선박건조 공법 및 사용되는 스키딩 시스템{A procedure of constructing ship by skidding super block and its skidding system}A procedure of constructing ship by skidding super block and its skidding system}

본 발명은 드라이 도크 내에서 선박 건조 공법에 관한 것으로서, 상세하게는 선수나 선미중 한 부분을 기존의 방식으로 건조하고, 나머지 부분은 기존에 만드는 블록의 3배 정도의 무게를 가진 더 큰 블록으로 미리 만들어 도크로 이동시켜 선수와 선미를 동시에 조립하여 완성시키는 슈퍼 블록 스키딩에 의한 선박건조 공법 및 사용되는 스키딩 시스템에 관한 것이다.The present invention relates to a ship construction method in a dry dock, and in particular, one part of the bow or stern is dried in a conventional manner, and the other part is a larger block having a weight about three times the existing block The present invention relates to a shipbuilding construction method and a skidding system used by a super block skiding, which is prefabricated and moved to a dock to assemble and complete a bow and a stern simultaneously.

기존의 선박 건조 방법은 도 1과 도 2에 도시되어 있듯이, 바다(8)와 인접한 드라이 도크(1)의 측면으로 전작업장(2)을 두어 미리 탑재블럭(6)을 조립한 다음, 골리앗 크레인(4)을 사용하여 도크(1)로 이동하여 용접이나 조인트 작업으로 상기 탑재블럭(6)을 조립한다. 이렇게 완성된 조립블럭(3) 들은 지지대(7) 위에 놓여져 조립되어 완성된다.The conventional ship construction method is as shown in Figures 1 and 2, the pre-installation block (6) is assembled in advance by placing the pre-working site (2) to the side of the dry dock (1) adjacent to the sea (8), and then goliath crane (4) is used to move to the dock (1) to assemble the mounting block (6) by welding or joint work. The completed assembly blocks 3 are placed on the support 7 to be assembled and completed.

이때 탑재 위치에 탑재블럭(6)을 이동시키는 골리앗 크레인(4)은 최대 450톤을 들 수 있으나 최대 용량보다 작은 350톤 정도의 무게로 탑재 블럭(6)을 전 작업장(2)에서 만든다.At this time, the goliath crane 4 for moving the mounting block 6 to the mounting position may be up to 450 tons, but the mounting block 6 is made in the entire workshop 2 with a weight of about 350 tons smaller than the maximum capacity.

이와 같이 전작업장(2)에서 만든 300에서 350톤 정도의 무게를 가지도록 탑재블럭(6)을 제작하고, 제작된 탑재블럭(6)을 도크(1)로 골리앗 크레인(4)을 이용하여 이동시켜 탑재위치에 내려놓고 조립한다.As described above, the mounting block 6 is manufactured to have a weight of about 300 to 350 tons made at the previous work site 2, and the manufactured mounting block 6 is moved to the dock 1 using the goliath crane 4. Put it on the mounting position and assemble it.
