Description
본 발명은, 동일 드라이도크 내에서 동종 또는 이종의 선박 건조시에, 진수선박과 부분진수선박을 동시에 건조하면서 진수선박의 반출시에 부분진수선박을 균형을 유지한 상태에서 안정적으로 미부양시킬 수 있고, 부분진수선박의 건조단계에 상응하여 상이하게 강제주수하여 진수선박의 진수에 영향을 주지 않을 수 있는, 드라이도크 미부양 탠덤 공법을 적용한 선박건조공법에 관한 것이다.The present invention is capable of stably unsustaining the partial launching ship while maintaining a balance when the launching ship and the partial launching ship are simultaneously built while building the same or different ships within the same dry dock. In addition, it relates to a ship construction method applying the dry dock unsuspended tandem method, which can do not affect the launching of the launching ship by compulsory injection differently corresponding to the construction stage of the partial launching ship.
주지하는 바와 같이, 효율적인 대형선박건조를 위해 드라이도크방식(건조도크방식)에 의해 선박을 건조하는데, 드라이도크에서 선박블록을 건조하고 드라이도크에 해수를 유입시켜 선박을 부양시켜 안벽으로 인양하여 반출한다.As is well known, ships are built by the dry dock method (dry dock method) for efficient large ship construction.The ship blocks are built on the dry dock and seawater is introduced into the dry dock to lift the ship to the quay and take it out. do.
한편, 드라이도크내의 여유공간을 활용하여 진수선박과 부분진수선박을 동시에 건조하도록 하는 탠덤공법이 적용되고 있다.On the other hand, a tandem method is applied in which a launching ship and a partial launching ship are simultaneously built by utilizing the free space in the dry dock.
예를 들어, 초대형 컨테이너선의 진수선박과 VLCC의 부분진수선박의 탠덤공법 적용시에, 드라이도크 내로의 해수 유입시 부분진수선박의 격벽이 형성된 화물탱크구역의 부력으로 인해 선미끝단쪽으로 불균형하게 기울어져 부양되어서, 터그선박에 의한 진수선박의 인양시에 터그선박의 스크류회전에 의해 부분진수선박을 지지하는 반목이 쓰려져 부분진수선박이 전도될 가능성이 있어서, 초대형 컨테이너선의 진수선박과 부분진수선박을 동시에 건조할 수 없는 한계가 있다.For example, when applying the tandem method of launching ships of super-large container ships and partial launching ships of VLCC, when seawater flows into the dry dock, the bulkhead of the partial launching ship is disproportionately inclined toward the stern end due to the buoyancy of the cargo tank area. When the launching ship is lifted by the tug ship, the antagonist supporting the partial launching ship is used by the screw rotation of the tug ship, and the partial launching ship is likely to overturn. At the same time, there is a limit that cannot be dried.
이와 같은 한계를 해소하기 위한 선행기술로서, 한국 등록특허공보 제10-0796410호가 개시되어 있는데, 종래의 탠덤 건조공법에 적용되는 침수공법은, 도크내에서 탠덤건조공법에 의해 선박블록을 건조하는 단계와, 침수 대상선박에 주엔진, 꼬리 및 중간 축, 선미블록, 래싱 브리지 또는 해치커버의 주요탑재물을 설치하는 단계와, 진수선박 부양시 침수 대상선박의 카고/홀드 발라스트 및 일부 이중 바닥 탱크에 물을 자연 유입하여 선박을 동일위치에 침수시키는 단계와, 진수선박의 예인후 침수된 선박건조를 진행하는 단계로 구성되어, 탑재물량을 모두 탑재 후 선체를 침수시켜 선체이동없이 동일 위치에서 건조를 완료하도록 한다.As a prior art for solving this limitation, Korean Patent Publication No. 10-0796410 is disclosed. The submersion method applied to the conventional tandem construction method is a step of building a ship block by a tandem construction method in a dock. Wow, installing the main engine, tail and intermediate shaft, stern block, lashing bridge or hatch cover on the vessel to be submerged, and on the cargo/hold ballast and some double bottom tanks of the submerged vessel when floating a launching vessel. It consists of the step of submerging the ship at the same location by naturally inflowing water, and the step of proceeding to build the submerged ship after towing the launching ship.After loading all the loads, the ship is submerged and the ship is built at the same location without moving. Let it be done.
하지만, 부분진수선박에 주요탑재물이 탑재된 상태에서, 진수선박 부양을 위해 유입되는 물에 의해 카고/홀드 발라스트 및 일부 이중 바닥 탱크로 자연 유입시켜 부분진수선박을 침수시키는데, 도 1에 도시된 바와 같이, 진수선박을 진수하기 전에 부분진수선박에 주요탑재물 탑재를 모두 완료한 후에만 가능하여, 진수선박의 건조가 완료된 상태에서 부분진수선박의 건조단계에 따라 진수선박의 인양시기가 지연되는 문제점이 있고, 도크 내로 자연 유입된 물, 즉 해수에 의해 부분진수선박을 침수시켜 염분 및 염소에 의한 선체 부식 가능성이 있고, 선체부식방지를 위한 선행공정 또는 후행공정을 수반하여 공기가 지연되는 문제점이 있다.However, in the state where the main loads are mounted on the partial launching ship, the partial launching ship is flooded by naturally entering the cargo/hold ballast and some double-bottom tanks by the water flowing in to support the launching ship. As described above, it is possible only after completing the loading of the main loads on the partial launching vessel before launching the launching vessel, and the salvage timing of the launching vessel is delayed depending on the construction stage of the partial launching vessel in the state that the launching vessel is completed. There is a problem, and there is a possibility of corrosion of the hull due to salt and chlorine by submerging the partially launched ship by the water naturally introduced into the dock, that is, seawater, and the air is delayed due to the preceding or following processes to prevent corrosion of the hull There is this.
이에, 부분진수선박의 건조단계와 무관하게 진수선박을 인양하도록 하여 공기지연을 최소화하고, 부분진수선박의 침수를 대비한 선체부식을 최소화할 수 있는 개선된 탠덤공법이 요구된다.Accordingly, there is a need for an improved tandem method capable of minimizing air delay by lifting the launching ship regardless of the construction stage of the partial launching ship, and minimizing hull corrosion in preparation for inundation of the partial launching ship.
본 발명의 사상이 이루고자 하는 기술적 과제는, 부분진수선박의 건조단계와 무관하게 진수선박을 인양하도록 하여 공기지연을 최소화하고, 부분진수선박의 침수를 대비한 선체부식을 최소화할 수 있는, 드라이도크 미부양 탠덤 공법을 적용한 선박건조공법을 제공하는 데 있다.The technical problem to be achieved by the idea of the present invention is that the launching ship is lifted irrespective of the construction stage of the partial launching ship, thereby minimizing air delay and minimizing hull corrosion in preparation for inundation of the partial launching ship. It is to provide a shipbuilding method using the unsuspended tandem method.

이하, 첨부한 도면을 참고로 하여 본 발명의 실시예에 대하여 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 용이하게 실시할 수 있도록 상세히 설명한다. 본 발명은 여러 가지 상이한 형태로 구현될 수 있으며 여기에서 설명하는 실시예에 한정되지 않는다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art may easily implement the present invention. The present invention may be implemented in various different forms, and is not limited to the embodiments described herein.
도 2를 참조하면, 본 발명의 실시예에 의한 드라이도크 미부양 탠덤 공법을 적용한 선박건조공법은, 전체적으로, 선각공사 및 선각부분공사 수행 단계(S110)와, 강제주수 단계(S120)와, 해수 유입 단계(S130)와, 진수선박 반출 단계(S140)와, 해수 배수 단계(S150)와, 잔여 선각부분공사 수행 단계(S160)와, 후속선박 선각부분공사 수행 단계(S170)로 구성되어서, 선박을 연속적으로 탠덤 건조가 가능하도록 하는 것을 요지로 한다.Referring to Figure 2, the ship construction method to which the dry dock unsuspended tandem method according to an embodiment of the present invention is applied is, as a whole, a hull construction and a hull partial construction performing step (S110), a forced watering step (S120), Consisting of a seawater inflow step (S130), a launch ship carrying step (S140), a seawater drainage step (S150), a remaining hull portion construction performing step (S160), and a subsequent ship hull portion construction performing step (S170), The point is to enable the ship to be continuously built in tandem.
구체적으로, 도 2 내지 도 5를 참조하여, 본 발명의 실시예에 의한 드라이도크 미부양 탠덤 공법을 적용한 선박건조공법을 상술하면 다음과 같다.Specifically, referring to FIGS. 2 to 5, a ship building method using a dry dock non-floating tandem method according to an embodiment of the present invention will be described in detail as follows.
우선, 선각공사 및 선각부분공사 수행 단계(S110)에서는, 도 3 및 도 5의 (a)에 도시된 바와 같이, 동일 드라이도크 내에서 1열 또는 2열로 복수의 동종 선박 또는 이종 선박의 선박블록을 각각 건조하되, 도크헤드(dock head) 인접영역에서 부분진수선박의 선각공사를 수행하고, 도크게이트(dock gate) 인접영역에서 진수선박의 선각부분공사를 수행한다.First, in the hull construction and hull partial construction performing step (S110), as shown in Figs. 3 and 5 (a), a ship block of a plurality of similar ships or different ships in one or two rows within the same dry dock Each of them is constructed, but the ship's hull construction is performed in the area adjacent to the dock head, and the ship's hull construction is performed in the area adjacent to the dock gate.
여기서, 진수선박 또는 부분진수선박은 특별히 제한되지는 않으나, 초대형 원유운반석(VLCC;Very Large Crude oil Carrier), 초대형 컨테이너선, LNG운반선, LNG추진선 또는 화학제품운반선의 대형건조선박 등일 수 있고, 500m 이상의 길이를 갖는 동일 드라이도크 내에서 1열로 또는 2열로 400m 전후의 전장(LOA; Length Of Overall)을 갖는 진수선박과 120m 전후의 전장을 갖는 부분진수선박을 동시에 건조할 수 있다.Here, the launching ship or the partial launching ship is not particularly limited, but may be a very large crude oil carrier (VLCC), a very large container ship, an LNG carrier, an LNG propulsion ship, or a large-scale construction ship of a chemical product carrier. , In the same dry dock having a length of 500m or more, it is possible to simultaneously build a launching ship with a length of around 400m (LOA) and a partial launching ship with a total length of around 120m in one or two rows.
참고로, 도크헤드와 부분진수선박간의 간격 및 도크게이트와 진수선박간의 거리는 5m 전후의 간격을 필요로 하고, 부분진수선박과 진수선박간의 거리는 10m 전후의 간격을 필요로 한다.For reference, the distance between the dock head and the partial launching vessel and the distance between the dock gate and the launching vessel requires a distance of around 5m, and the distance between the partial launching vessel and the launching vessel requires an interval of around 10m.
후속하여, 강제주수 단계(S120)에서는, 도 3에 도시된 바와 같이, 부분진수선박 내부로 펌프(P)를 통해 강제적으로 주수하여 도크 내로의 해수 유입시에 부분진수선박, 즉 부분진수선박의 선수부가 자체부력에 의해 부양되지 않도록 한다.Subsequently, in the forced watering step (S120), as shown in FIG. 3, a partial launching vessel, that is, a partial launching vessel, when seawater flows into the dock by forcibly pumping water into the partial launching vessel through the pump P. Make sure that the fore part of is not supported by its own buoyancy.
즉, 수온과 염분과 수압에 따라 가변되는 해수 밀도에 의한 부분진수선박의 부력을 상쇄하고 COG와 균형을 유지하도록, 부분진수선박의 격벽이 형성된 카고탱크(cargo tank) 내부에 펌프(P)를 통해 청수 또는 해수를 강제주수하여서 부분진수선박이 제위치에서 블록전도방지를 위한 반목(support)으로부터 부양되지 않도록 한다.In other words, to offset the buoyancy of the partial launching vessel due to the seawater density that varies depending on the water temperature, salinity and water pressure, and to maintain the balance with COG, a pump (P) is installed inside the cargo tank where the bulkhead of the partial launching vessel is formed. Clear water or seawater is forcibly poured through to prevent partial launching ships from being supported from support to prevent block fall in place.
한편, 도 4를 참조하면, 강제주수시에, 부분진수선박의 데크하우스(D/H;Deck House)(A) 및 엔진케이싱(engine casing)(B)의 탑재시에는, 부분진수선박의 선수부 즉, 엔진케이싱(B) 인접 좌우 한쌍의 SCO탱크(SCO TK(P),(S))에 각각 강제주수하되, VLCC기준으로, 각각 8000톤 전후해서 주수하여 부분진수선박의 선수부가 부양되지 않도록 하면서 선미의 후단으로 치우친 COG와 균형을 이루도록하여 선미의 전후가 불균형하게 기울어져 부분부양되지 않도록 한다. 예컨대, No.5 SCO TK(P)에는 8000톤을 주수하고, No.5 SCO TK(S)에는 7,950톤을 주수하여 총 15,950톤을 주수할 수 있다.On the other hand, referring to FIG. 4, when the deck house (D/H) and the engine casing (B) of a partial launching ship are mounted during forced injection, the bow part of the partial launching ship In other words, it is forcibly injected into a pair of left and right SCO tanks (SCO TK(P), (S)) adjacent to the engine casing (B), but based on VLCC, it is injected around 8000 tons each, so that the bow part of the partial launching ship is not supported. While avoiding it, balance the COG that is biased toward the rear end of the stern, so that the front and rear of the stern are not inclined unbalanced and partially lifted. For example, 8000 tons can be injected into No.5 SCO TK(P) and 7,950 tons can be injected into No.5 SCO TK(S), giving a total of 15,950 tons.
또는, 부분진수선박의 데크하우스(A) 및 엔진케이싱(B)의 미탑재시에는, 탑재시에 비해 COG가 선미 후단으로 덜 치우쳐, 엔진케이싱(B) 인접 좌우 한쌍의 SCO탱크에 각각 대부분 강제주수하고, 좌우 한쌍의 슬롭탱크(SLOP TK(P),(S))에 각각 나머지 강제주수하되, VLCC기준으로, 좌우 한쌍의 SCO탱크에 각각 7000톤 전후해서 주수하고 좌우 한쌍의 슬롭탱크에 각각 800톤 전후해서 주수하여 선미가 부양되지 않도록 하면서 선미의 후단으로 상대적으로 덜 치우친 COG와 균형을 이루도록하여 선미의 전후가 불균형하게 기울어져 부분부양되지 않도록 한다. 예컨대, No.5 SCO TK(P,S)에 각각 7100톤을 주수하고, SLOP TK(P)에는 860톤을 주수하고 SLOP TK(S)에는 750톤을 주수하여 총 15810톤을 주수할 수 있다.Alternatively, when the deckhouse (A) and engine casing (B) of a partial launch ship are not installed, the COG is less skewed to the rear end of the stern than when mounted, and most of them are forced into the left and right pair of SCO tanks adjacent to the engine casing (B). Water, and the remaining forced injection into the left and right pair of slop tanks (SLOP TK(P), (S)), but based on VLCC, the left and right pair of SCO tanks each with around 7000 tons of water, and the left and right pair of slop tanks. The water is injected around 800 tons each so that the stern is not lifted, and it is balanced with the COG that is relatively less skewed toward the rear end of the stern, so that the front and rear of the stern are inclined unbalanced to prevent partial lift. For example, 7100 tons each can be injected into No.5 SCO TK(P,S), 860 tons are injected into SLOP TK(P), 750 tons can be injected into SLOP TK(S), and a total of 15810 tons can be injected. .
여기서, SCO탱크 및 슬롭탱크에 펌프(P)를 통해서 청수 또는 해수를 강제주수할 수 있는데, 해수의 강제주수시에는, 염분 및 염소에 의한 선체의 부식을 최소화하기 위해 해수담수화장치를 통해 염분 및 염소를 제거한 후 주수할 수도 있다.Here, fresh water or seawater can be forcibly poured into the SCO tank and the slop tank through the pump (P). In the case of forced injection of seawater, salt through a seawater desalination device is used to minimize corrosion of the hull due to salt and chlorine. And after removing chlorine, it may be watered.
이에, 부분진수선박의 건조단계에 상응하여, 상이한 방식으로 청수 또는 해수를 강제주수하여 부분진수선박의 균형을 유지한 상태에서 안정적으로 미부양시키고, 진수선박의 진수에 영향을 주지 않아 공기지연을 최소화할 수 있다.Accordingly, in accordance with the construction stage of the partial launching vessel, fresh water or seawater is forcibly injected in a different manner to stably unsuspend while maintaining the balance of the partial launching vessel, and the air delay does not affect the launching of the launching vessel. Can be minimized.
참고로, 펌프(P)는 드라이도크에 배치되는 것으로 도시되어 있으나, 부분진수선박에 탑재되어 강제주수하도록 할 수 있고, 슬롭탱크는 각종 탱크 클리닝 후에 형성되는 기름과 해수의 혼합물 또는 기관실에서 흘러나오는 폐유의 유성혼합물을 저장하여 보관하는 탱크로서, 기름에 의한 해양오염을 방지하고 화물류 손실분을 감소시키는 목적으로 배치된다.For reference, the pump (P) is shown to be disposed on a dry dock, but it can be mounted on a partial launching vessel to force injection, and the slop tank is a mixture of oil and seawater formed after various tank cleaning or flows from the engine room. As a tank to store and store the oily mixture of waste oil that comes out, it is arranged for the purpose of preventing marine pollution by oil and reducing the loss of cargo.
후속하여, 해수 유입 단계(S130)에서는, 도 5의 (b)에 도시된 바와 같이, 드라이도크의 도크게이트를 개방하여 해수를 유입시켜 진수선박을 부양시키고, 부분진수선박을 제위치에서 미부양시킨다.Subsequently, in the seawater inflow step (S130), as shown in (b) of FIG. 5, the dock gate of the dry dock is opened to induce seawater to float the launching ship, and the partial launching ship is unsuspended in place. Let it.
후속하여, 진수선박 반출 단계(S140)에서는, 도 3 및 도 5의 (c)에 도시된 바와 같이, 부양된 진수선박을 터그선박에 의해 도크게이트 외부 안벽으로 인양하여 반출한다.Subsequently, in the launching ship unloading step (S140), as shown in FIGS. 3 and 5C, the suspended launching ship is lifted to the outer quay wall of the dock gate by the tug ship and carried out.
후속하여, 해수 배수 단계(S150)에서는, 도크게이트를 폐쇄하여 드라이도크로부터 해수를 배수한다.Subsequently, in the seawater drainage step (S150), seawater is drained from the dry dock by closing the dock gate.
후속하여, 잔여 선각부분공사 수행 단계(S160)에서는, 도 5의 (d)에 도시된 바와 같이, 부분진수선박으로 강제주수된 청수 또는 해수를 배수하고, 침수된 동일위치에서 부분진수선박에 대한 나머지 잔여 선각부분공사를 수행하여 진수선박을 건조한다.Subsequently, in the remaining hull partial construction performing step (S160), as shown in Fig. 5(d), the fresh water or seawater forcibly injected into the partial launching vessel is drained, and the partial launching vessel at the same location where it is flooded. Construction of the remaining hull parts for the rest of the ship is performed to build the launching ship.
후속하여, 후속선박 선각부분공사 수행 단계(S170)에서는, 도 5의 (d)에 도시된 바와 같이, 진수선박 반출위치에 후속선박의 선각부분공사를 수행한다.Subsequently, in the subsequent ship hull portion construction performing step (S170), as shown in FIG. 5 (d), the hull portion construction of the subsequent ship is performed at the launching ship carrying location.
따라서, 전수한 바와 같은 드라이도크 미부양 탠덤 공법을 적용한 선박건조공법의 구성에 의해서, 종래기술의 침수공법에 의한 진수선박 부양을 위해 자연유입된 해수에 의해 주요 탑재물이 탑재된 부분진수선박을 침수시키는 것과 대비하여, 별도로 청수 또는 해수를 강제주수하여 선체부식을 최소화하면서 부분진수선박을 미부양시키며, 동일 드라이도크 내에서 동종 또는 이종의 선박 건조시에, 진수선박과 부분진수선박을 동시에 건조하면서 진수선박의 반출시에 부분진수선박을 균형을 유지한 상태에서 안정적으로 미부양시킬 수 있으며, 부분진수선박의 건조단계에 상응하여 상이하게 강제주수하여 진수선박의 진수에 영향을 주지 않을 수 있고, 탠덤공법에 의해 공기를 단축하면서 대형건조선박을 연속적으로 건조가능하도록 할 수 있다.Therefore, by the construction of the shipbuilding method that applies the dry dock unsuspended tandem method as previously described, the partial launching vessel with the main payload is submerged by the seawater naturally flowing in to support the launching vessel by the inundation method of the prior art. In contrast, fresh water or seawater is separately forcibly poured to minimize corrosion of the hull, while partially floating ships are not lifted, and when the same or different ships are built within the same dry dock, both the launching ships and the partial launching ships are built at the same time. While carrying out the launching ship, the partial launching ship can be stably unsuspended while maintaining a balance, and it may not affect the launching of the launching ship by compulsory injection differently according to the construction stage of the partial launching ship. In addition, it is possible to continuously dry large-sized ships while shortening the air by the tandem method.
