Description

두 대의 해상크레인을 이용한 대형 선체 블록의 런칭 및 탑재방법{Big body block launching and loading method using two sea cranes} Big body block launching and loading method using two sea cranes}

본 발명은 두 대의 해상크레인을 이용한 대형 선체 블록의 런칭 및 탑재방법에 관한 것이다. 더욱 상세하게는 2대의 3600톤 해상크레인으로 대형 선체 블록을 리프팅 하여 해상에 런칭한 다음 해상 터그 보트로 이동하여 탑재하는 건조방법에 관한 것이다.The present invention relates to a method of launching and mounting a large hull block using two offshore cranes. More specifically, it relates to a drying method of lifting a large hull block with two 3600 ton offshore cranes, launching it on the sea, and then moving and loading the offshore tug boat.

일반적으로, 선박의 주문으로 시작하여 설계, 건조, 인도로 이루어지는 조선공업은 그 과정에서 나타나는 영업상의 채산성에 의해 그 산업의 생존 및 성공이 판가름 지어진다.In general, the shipbuilding industry, which begins with the ordering of ships, is designed, built, and delivered, determines the survival and success of the industry by the profitability of the business.

이와 같은 채산성을 결정짓는 중요한 요소 중 한가지는 선박의 건조 방식에서 나타나는 생산성이며, 모든 조선공업은 선박 건조의 생산성 향상을 위하여 노력하고 있다. 이러한 이유로 블록건조법이 등장하게 되었다.One of the important factors that determine profitability is the productivity of shipbuilding methods, and all shipbuilding industries are striving to improve the productivity of shipbuilding. For this reason, block drying has emerged.

상기의 블록 건조법은 우선 선체를 수십 개 혹은 수백 개의 블록으로 분할하 여 개개의 블록들을 지상에서 조립 제작하고, 그 제작된 블록들을 순차적으로 선대 위에 탑재하여 하나의 선체로 조립해 내는 방법이다.The block drying method is a method of firstly dividing the hull into dozens or hundreds of blocks and assembling and manufacturing individual blocks on the ground, and assembling them into one hull by sequentially mounting the manufactured blocks on the ship's fleet.

특히, 블록의 형상에 따라 가장 적합한 공장에서 가장 효율적인 공법으로 만들어 완성된 블록들은 도장이 이루어진다.In particular, according to the shape of the block is made of the most efficient process in the factory is completed, the finished blocks are painted.

이후, 도장까지 마친 블록들은 탑재기간을 줄이기 위하여 크레인이 들어올릴 수 있는 중량범위까지 몇 개의 블록씩 결합 되게 되는데, 이와 같이 복수 개의 블록을 하나로 결합시키는 작업을 PE(Pre-Erection)라 한다.After that, the blocks are finished until the painting is combined by a few blocks up to the weight range that the crane can lift in order to reduce the mounting period, this operation of combining a plurality of blocks into one is called PE (Pre-Erection).

이러한 PE 작업은 여러 개의 소형 블록들을 하나의 큰 블록으로 뭉쳐서 한번에 탑재시킬 수 있어 작업시간을 단축시킬 수 있는 장점이 있으며, 이로 인하여 선박의 생산 능률을 증대시킬 수 있게 된다.This PE work can combine several small blocks into one big block and mount them at once, which reduces the working time, thereby increasing the production efficiency of the ship.

그러나 상기와 같은 PE 작업이 원활히 이루어지기 위해서는 대형 선체 블록을 운반 및 탑재할 수 있는 크레인의 작업 용량이 커야 한다.However, in order for the PE work to be performed smoothly, the working capacity of the crane that can carry and mount the large hull block must be large.

한편, 종래의 대형 선체 블록의 이동 및 탑재는 일반적으로 해상 크레인 1대를 사용한 공법이 많이 적용되었으나, 선체 블록이 대형화되고 제작 공기를 단축하기 위해서는 최근 해상 크레인 2대를 사용하여 탑재하는 방법은 해상크레인을 먼 곳으로 이동하지 않고, 정 위치에서 리프팅하여 전진이나 후진으로 탑재하는 공법이 사용되기도 한다.On the other hand, the conventional large hull block movement and mounting was generally applied to a large number of methods using a single offshore crane, but in order to increase the size of the hull block and shorten the manufacturing air, the method of mounting using two offshore cranes recently Instead of moving the crane far away, a method of lifting it in place and mounting it forward or backward is sometimes used.

이와 같이 2대의 해상 크레인으로 구성된 종래의 선체 블록 리프팅 탑재 공법은 먼 곳으로 리프팅하여 해상이동 후 탑재를 하지 못하는 문제점이 발생하였다.Thus, the conventional hull block lifting mounting method consisting of two offshore cranes has a problem that can not be mounted after moving by lifting to a distant place.

이에, 본 발명은 상기한 문제점을 해결하기 위한 것으로서 본 발명의 목적은 2대의 3600톤 해상크레인으로 대형 선체 블록을 리프팅 하여 해상에 런칭한 다음 해상 터그 보트로 이동하여 탑재함으로써 선박건조 비용을 대폭 절감하고 공기단축과 2대의 해상크레인을 사용하여 대형 선체 블록을 먼 곳으로 이동 후 탑재할 수 없는 한계를 극복하는 데 있다. Accordingly, the present invention is to solve the above problems, the object of the present invention is to lift the large hull block with two 3600 tons offshore cranes launched on the sea and then moved to the offshore tug boat to significantly reduce the ship construction cost It is to overcome the limitation that the large hull block cannot be mounted after moving to the far place by using air shortening and two marine cranes.

상기한 본 발명의 목적을 달성하기 위한 기술적 사상으로서 본 발명에 의하면, 육상의 안벽 작업장에서 선체 블록(11)을 대형화로 조립한 후 해상크레인 2대(10)(20)를 사용하여 대형 선체 블록(11)을 1차로 리프팅 하는 단계; 상기 선체 블록(11)을 해상에 런칭시키는 단계; 해상 터그 보트를 이용하여 탑재 위치까지 상기 선체 블록(11)과 해상크레인(10)(20) 2대를 동시에 이동시키는 단계; 및 다시 해상크레인(10)(20) 2대를 사용하여 상기 선체 블록(11)을 2차로 리프팅한 후, 탑재시키는 단계;를 포함하는 것을 특징으로 하는 대형 선체 블록의 런칭 및 탑재 방법을 제시한다.According to the present invention as a technical idea for achieving the above object of the present invention, the large hull block using two marine cranes (10, 20) after assembling the hull block (11) in a large scale in the coastal wall of the land First lifting (11); Launching the hull block (11) at sea; Simultaneously moving the hull block (11) and two marine cranes (10) (20) to a loading position using an offshore tug boat; And again lifting and then mounting the hull block 11 using two offshore cranes 10 and 20, thereby launching and mounting a large hull block. .

본 발명에 의하면, 종래의 대형 선체 블록을 해상 크레인 1대 혹은 2대를 사 용하여 리프팅 후 정 위치에서 탑재하는 공법과는 달리 안벽의 작업장을 최대한 활용하고 대형화 되어가는 선체 블록들을 해상 크레인 2대를 사용하여 먼 곳으로 이동하여 탑재하는 방법을 사용함으로써 선박건조 비용을 대폭 절감하고 공기단축과 2대의 해상크레인을 사용하여 대형 블록을 먼 곳으로 이동 후 탑재할 수 없는 한계를 극복할 수 있다. 또한, 도크의 회전율을 높이고 쉽고 안전하게 대형 블록을 탑재할 수 있다. According to the present invention, unlike the conventional method of lifting a large hull block using one or two offshore cranes and mounting it in a fixed position, it makes full use of the workshop of the inner wall and uses two offshore cranes for the enlarged hull blocks. By using the method of moving and mounting far away, the shipbuilding cost can be greatly reduced, and the limitation of the inability to mount large blocks after moving far away using air shortening and two offshore cranes can be overcome. In addition, the turnover of the dock can be increased, and large blocks can be mounted easily and safely.

이하, 본 발명의 실시 예에 대한 구성 및 그 작용을 첨부한 도면을 참조하면서 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

본 발명의 기술적 특징은 일반적으로 해상크레인 1대를 사용하여 해상크레인 용량에 맞는 하나의 선체 블록을 탑재 위치까지 리프팅 하여 해상 이동 후 드라이 도크(Dry Dock)나 플로팅 도크 및 먼저 런칭된 해상 구조물 위에 탑재하는 공법을 사용하였으나, 육상에서 선체 블록을 대형화로 조립 후 3600톤 해상크레인 2대를 사용하여 대형 선체 블록을 리프팅한 후, 바다에 그 대형 블록을 런칭시킨 다음 해상 터그 보트로 탑재 위치까지 대형 선체 블록과 3600톤 해상 크레인 2대를 동시에 이동한 다음 다시 3600톤 해상 크레인 2대를 사용하여 대형 선체블록을 리프팅 하여 탑재하는 것이다.Technical features of the present invention are generally mounted on a dry dock or floating dock and the first launched offshore structure after lifting by lifting one hull block suitable for offshore crane capacity to a mounting position using a single offshore crane. However, after assembling the hull block on a large scale on the land, after lifting the large hull block using two 3600 ton offshore cranes, launching the large block into the sea, then the large hull to the loading position by the offshore tug boat The block and two 3600 ton offshore cranes are moved at the same time, and then the large hull block is lifted and mounted using two 3600 ton offshore cranes.
