크레인 진수를 이용한 탠덤 건조공법{Tandem ship-building method by crane-launching}Tandem ship-building method by crane-launching}

본 발명은 크레인 진수를 이용한 탠덤 건조공법에 관한 것으로, 보다 상세하게는 탠덤 건조공법에 따라 도크 내 탠덤 선박의 건조 시 기존 미탑재물을 추가 탑재한 후 크레인의 견인력과 도크 내 유입되는 해수에 의한 부력을 사용하여 탠덤 건조선박을 부양시켜 탠덤 건조선박의 부양 후 탑재 물량을 감소시킬 수 있도록 하는 크레인 진수를 이용한 탠덤 건조공법에 관한 것이다.The present invention relates to a tandem drying method using the launching of the crane, and more specifically, to mounting the existing unloaded when the tandem ship in the dock according to the tandem drying method additional load of the crane and buoyancy due to the seawater flowing into the dock It relates to a tandem drying method using a crane launching to support the tandem dry ship to reduce the amount of loading after the support of the tandem dry ship using.

이하, 도면을 참조하여 배경기술과 그 문제점에 대하여 설명하면 다음과 같다.Hereinafter, a background art and a problem thereof will be described with reference to the accompanying drawings.

일반적으로 전통적인 조선소는 경사진 땅 위에 레일을 설치하고 그 위에서 배를 건조해서 건조가 완료되면 레일로 배를 경사진 방향으로 미끄러뜨려 진수하는 방법을 사용한다.Traditionally, shipyards install rails on sloping ground, dry the ships on them, and when they are finished, slide the ships on the rails in a sloping direction to launch them.

이런 방식을 경사선대 방식이라고 하는데, 아직도 중소 조선소나 일부 대형 조선소에서 경사선대 방식을 이용한다.This method is called the inclined fleet method, and still used inclined fleet method in small and medium shipyards and some large shipyards.

하지만, 최근에는 보다 안전하고, 큰 선박건조 및 건조시의 효율성을 위해 건조도크에서 선박을 건조하는 것이 일반적인 추세이다.However, in recent years, it is a general trend to build a ship in a dry dock for safety and large shipbuilding efficiency.

건조도크 방식은 도크에서 선박을 건조하고 배를 진수할 때는 도크에 물을 채운 후 도크 게이트를 개방하여 건조된 선박을 도크 밖으로 내보내 나머지 선박 건조과정을 진행하는 방식이다.The dry dock method is a method of constructing a ship in a dock and launching a ship, filling the dock with water, opening the dock gate, and sending the dried ship out of the dock to proceed with the rest of the ship construction process.

하지만 이와 같이 도크의 제원에 비하여 선박 하나를 건조하고 도크 게이트를 열고 물을 유입시킨 후, 선박을 부양시켜 진수된 선박을 도크 밖으로 터그보트(Tug-boat)를 이용하여 이동시켜 후반 선박 건조작업을 진행하는 것은 도크 내 여유 공간 활용 차원에서 선박을 대량으로 생산하는데 매우 비효율적이라는 문제점이 있었다.However, as compared to the specifications of the dock, one ship is built, the dock gate is opened, water is introduced, and the ship is floated and the launched ship is moved out of the dock by using a tug-boat. There was a problem that proceeding was very inefficient for mass production of ship in terms of free space in the dock.

이와 같은 문제점을 해결한 것이 탠덤 부상건조공법인데, 도크의 여유공간을 이용하면 하나의 도크에서 2척 ~ 4척의 선박을 동시에 건조할 수 있다.Solving this problem is a tandem floating drying method, using the free space of the dock can be built at the same time two to four ships in one dock.

따라서 탠덤 부상공법은 완성된 선박을 부양시켜 도크 밖으로 내보낼 때 필히 부분 완성된 선박 역시 부양되도록 선 작업을 한 후, 진수 선박과 함께 부양 후, 진수 선박이 도크 밖으로 나가면, 도크 게이트를 닫고 다시 자리를 위치시킨 후 다시 물이 빠지면 이동된 위치 또는 제자리 위치에서 나머지 선박 건조작업을 진행하게 된다.Therefore, tandem flotation method requires the ship to be partially completed when the ship is lifted and released out of the dock, and after the ship is floated together with the launch ship, when the launch ship goes out of the dock, the dock gate is closed and relocated. When the water is drained again after positioning, the remaining ship construction work is carried out in the moved position or in place.

하지만, 상기와 같은 종래의 탠덤 부상공법의 문제점은 도크 제원의 제약으로 인하여 탠덤 지역이 전장대비 55%이하의 경우 부양 시 선박 부상용 흘수(Draft, 최대 7.1m)를 확보코자 탠덤 선박의 탑재물량을 제한하는 방법으로 부양을 실시하 여 부양 후 도크 내 건조 공기부족으로 인한 공정차질 및 돌관 작업에 따른 과다 소요공수가 투입되는 문제점이 발생된다는 것이다.However, the problem of the conventional tandem flotation method is to secure the draft (up to 7.1m) for the ship when the tandem area is less than 55% of the battlefield due to the limitation of dock specifications. After the flotation is carried out in a limiting manner, there is a problem that excessive required air flow due to process disruption and stone work due to lack of dry air in the dock occurs.

여기서 상기 탠덤 부상공법에 따른 부양 전 미 탑재 물량은 주엔진(Main Engine), 꼬리 및 중간 축(Tail & Intermediate Shaft), 래싱 브리지(Lashing Bridge), 해치커버(Hatch Cover) 등이다.Here, the unloaded quantity of the flotation according to the tandem flotation method is a main engine, a tail and intermediate shaft, a lashing bridge, a hatch cover, and the like.

상기와 같은 미 탑재로 인해 부양이 끝난 후 도크에서 건조시의 문제점으로는 부양 후 꼬리 및 중간 축 탑재 및 주 엔진 탑재에 따른 데크 하우스 탑재순연으로 육상수전(Shore power-육상에서 전원을 공급 받는 것)의 순전 차질이 있다는 문제점과, 부양 후 선미 블록탑재로 본견투(Final sighting) 순연에 따른 프로펠러와 러더 설치공기가 부족하다는 문제점이 있었다.The problem of drying in the dock after the flotation due to the non-mounting as above is that the deck house is mounted on the tail and middle shaft after the flotation and the main engine is mounted. There was a problem that there was a net disruption of) and the lack of propellers and rudder installation air due to the stern block mounting followed by the final sighting.

또한, 부상된 선박블록이 고정되지 못하고 움직여서 부양된 선박 블록끼리 부딪히거나, 도크의 벽과 부딪혀 건조 중인 선박블록이 파손 또는 훼손되는 문제점이 있으며, 미완성된 선박블록의 중심을 잡아 부양시키는 것 또한 매우 어렵다는 문제점이 있었다.In addition, there is a problem that the floating ship block is not fixed, the floating ship blocks collide with each other, or the building ship blocks are damaged or damaged due to collision with the walls of the dock, and to hold and support the center of the unfinished ship block. There was a problem that was very difficult.

본 발명은 상기와 같은 목적을 해소하기 위한 것으로, 그 목적은 탠덤 선박의 부양 시 해수에 의한 부력과 더불어 건조 도크에 유휴하고 있는 크레인의 견인력을 더하여 탠덤 선박을 부양시킬 수 있도록 함으로써 기존 미탑재물을 추가 탑재한 후 탠덤 선박을 부양시킬 수 있도록 하여 탠덤 선박의 잔여 탑재물의 도크 건조공기를 단축시킬 수 있도록 하는 크레인 진수를 이용한 탠덤 건조공법을 제공하는 것이다.The present invention is to solve the above object, the purpose is to add the traction force of the crane idle to the dry dock as well as buoyancy by the seawater during the floatation of the tandem ship by supporting the tandem ship It is to provide a tandem drying method using the launching of the crane to be able to support the tandem ship after additional loading to shorten the dock drying air of the remaining payload of the tandem ship.

본 발명의 다른 목적은, 탠덤 선박이 크레인에 의해 고정된 상태로 부양되도록 함으로써 미완성의 탠덤 선박의 중심을 잡아 안전하게 부양시킴과 더불어, 부양된 선박 블록끼리 부딪히거나 도크 벽과 부딪히는 현상을 방지할 수 있는 크레인 진수를 이용한 탠덤 건조공법을 제공하는 것이다.Another object of the present invention is to hold the center of the unfinished tandem ship by allowing the tandem ship to be held in a fixed state by a crane to safely support it, and to prevent the floating ship blocks from colliding with the dock wall. It is to provide a tandem drying method using a crane launching.

상기 목적을 달성하기 위한 본 발명은, 도크 내에서 일반적인 탠덤 건조공법에 따라 선박 블록을 건조하는 단계; 상기 도크 내 진수 선박의 부양 전에 탠덤 선박에 기존 미탑재물을 추가 설치하여 건조하는 단계; 상기 도크 내에 해수를 유입하여 진수선박의 부양 시, 자연 유입되는 해수에 의한 부력과 더불어, 탠덤 선박의 래싱/러그에 도크에 유휴하고 있는 크레인을 연결하여 크레인의 견인력을 더하여 탠덤 선박을 부양시키는 단계; 및 상기 부양된 진수선박을 도크 밖으로 터그보트에 의해 예인함과 동시에 도크 게이트가 닫히면 탠덤 선박의 자리를 위치시킨 후 해수가 빠지면 이동된 위치 또는 제자리 위치에서 탠덤 선박의 나머지 선박 건조작업을 진행하는 단계;를 포함하는 것을 특징으로 하는 크레인 진수를 이용한 탠덤 건조공법을 제공하는 것이다.The present invention for achieving the above object, drying the ship block in accordance with the general tandem drying method in the dock; Adding and installing an existing unloaded article on a tandem vessel before flotation of the launching vessel in the dock; When the seawater flows into the dock to support the launching vessel, the tandem ship is supported by adding the traction force of the crane by connecting the crane idled to the dock to the lashing / lug of the tandem ship and the buoyancy caused by the naturally introduced seawater. ; And towing the lifted launch ship out of the dock by a tugboat and simultaneously placing the tandem vessel when the dock gate is closed, and then proceeding to build the remaining vessels of the tandem vessel at the moved or in place position when the seawater is removed. It is to provide a tandem drying method using a crane launching, characterized in that it comprises a.

여기서, 상기 탠덤 선박의 부양 시 발생하는 운동으로 인해 크레인의 충격하중을 줄이기 위해 상기 래싱/러그 브리지와 크레인에는 댐핑부재가 더 설치될 수 있다.Here, a damping member may be further installed on the lashing / lug bridge and the crane in order to reduce the impact load of the crane due to the movement generated during the floatation of the tandem vessel.

그리고, 상기 크레인은 래싱/러그에 의해 탠덤 선박의 선미 부분에 연결되는 것이 바람직하다.The crane is preferably connected to the stern portion of the tandem vessel by lashing / lugging.

이와 같이 본 발명은 도크 내에 해수를 유입하여 진수선박의 부양 시, 자연 유입되는 해수에 의한 부력과 더불어 크레인의 견인력이 더해져서 탠덤 선박을 부양시킬 수 있도록 함으로써 종래의 일반적인 탠덤 건조공법과는 다르게 선박을 이루는 각각의 블록에 맞게 기존 미탑재물을 추가 탑재한 후에도 탠덤 선박을 부양시킬 수 있도록 함으로써 도크 내에서 부양 후 탑재 물량을 감소시켜 진수선박의 부양 단계 후, 탠덤 선박의 도크 건조공기를 단축시킬 수 있는 장점이 있다.As described above, the present invention allows the tandem vessel to be supported by the lifting force of the crane along with the buoyancy by the naturally introduced seawater when the launching of the seawater is introduced into the dock to support the tandem vessel, unlike the conventional tandem drying method. It is possible to support the tandem ship even after additional existing unloaded loads are added to each block forming a block, thereby reducing the amount of loading after the float in the dock to shorten the dock drying air of the tandem ship after the flotation step of the launching ship. There is an advantage.

또한, 탠덤 선박이 크레인에 의해 고정된 상태로 부양됨으로써 미완성된 탠덤 선박의 중심을 잡아 안전하게 부양시킬 수 있을 뿐만 아니라, 부양된 선박 블록끼리 부딪히거나 도크의 벽과 부딪혀 건조 중인 선박 블록이 파손되거나 훼손되는 등의 문제점을 해소할 수 있도록 하여 산업상 그 이용이 크게 기대되는 발명인 것이다.In addition, the tandem ship is held in a fixed state by a crane to secure the center of the unfinished tandem ship and to lift it safely, and the ship blocks that are being built are damaged by colliding with each other or by hitting the walls of the dock. It is an invention that is expected to use greatly in the industry by being able to solve the problems such as being damaged.

다시, 도 1 및 도 2를 참조하면, 종래의 일반적인 탠덤 건조공법에서는 부양 시 선박 부상용 흘수(Draft)를 확보코자 주요탑재물의 탑재물량이 제한됨으로써 주요탑재물인 주엔진(12), 꼬리 및 중간 축(13), 선미블록(14), 래싱 브리지(15), 해치커버(16)가 미 탑재되었음을 알 수 있는 반면에, 본 발명에 따른 크레인 진수를 이용한 탠덤 건조 공법에서는 진수선박의 부양 시, 자연 유입되는 해수에 의한 부 력과 더불어 크레인의 견인력이 더해져서 탠덤 선박을 부양시킴으로써 주엔진(12)은 엔진룸(110)에 설치되어 있으며, 꼬리 및 중간 축(13)은 탠덤 선박(11)의 하부에 설치되어 있고, 선미블록(14)은 방향타(111) 상부에 탑재되어 있으며, 래싱 브리지(15)와 해치커버(16)는 탠덤 선박(11)의 상부에 탑재되어 있음을 알 수 있다.Referring back to Figures 1 and 2, in the conventional tandem drying method, the main engine 12, the tail and the middle of the main load by limiting the payload of the main load in order to secure the draft for the ship floating during flotation It can be seen that the shaft 13, the stern block 14, the lashing bridge 15, the hatch cover 16 is not mounted, while in the tandem drying method using the crane launching according to the present invention, The main engine 12 is installed in the engine room 110 by supporting the tandem ship by adding the traction force of the crane with the buoyancy caused by the naturally introduced sea water, and the tail and the intermediate shaft 13 are the tandem ship 11. It is installed at the bottom of the stern block 14 is mounted on the rudder 111, it can be seen that the lashing bridge 15 and the hatch cover 16 is mounted on the top of the tandem vessel (11). .

즉, 본 발명에서는 도크(10) 내에 해수를 유입하여 진수선박의 부양 시, 자연 유입되는 해수에 의한 부력과 더불어 크레인(17)의 견인력이 더해져서 탠덤 선박(11)을 부양시킬 수 있도록 함으로써 종래의 일반적인 탠덤 건조공법과는 다르게 선박을 이루는 각각의 블록에 맞게 기존 미탑재물을 추가 탑재한 후에도 탠덤 선박(11)을 부양시킬 수 있도록 함으로써 도크(10) 내에서 부양 후 탑재 물량을 감소시켜 진수선박의 부양 단계 후, 탠덤 선박(11)의 도크 건조공기를 단축시킬 수 있도록 한다.That is, in the present invention, when the seawater is introduced into the dock 10 to lift the launching vessel, the tandem vessel 11 can be supported by adding the traction force of the crane 17 together with the buoyancy caused by the naturally introduced seawater. Unlike the general tandem drying method, the tandem ship 11 can be supported even after the existing unloaded items are additionally mounted for each block constituting the ship, thereby reducing the amount of loading after flotation in the dock 10 to launch the ship. After the levitation step, to shorten the dock dry air of the tandem vessel (11).

또한, 탠덤 선박(11)이 크레인(17)에 의해 고정된 상태로 부양됨으로써 미완성된 탠덤 선박(11)의 중심을 잡아 안전하게 부양시킬 수 있을 뿐만 아니라, 부양된 선박 블록끼리 부딪히거나 도크(10)의 벽과 부딪혀 건조 중인 선박 블록이 파손되거나 훼손되는 등의 문제점을 해소할 수 있도록 한다.In addition, the tandem ship 11 is held in a fixed state by the crane 17, so as to grasp the center of the unfinished tandem ship 11 to support it safely, and the lifted ship blocks collide with each other or dock 10 It is possible to solve problems such as damage to or damage to the ship block under construction by hitting the wall.
