Description

선박의 문풀 개폐장치{Apparatus for opening and closing Moon-Pool of ship}Apparatus for opening and closing Moon-Pool of ship}

본 고안은, 선박의 문풀 개폐장치에 관한 것으로서, 보다 상세하게는, 문풀로 인한 선체의 저항 증가, 속도저하, 소요 마력 증가, 연료소모증가, 선체의 손상 등을 최소화하기 위해 일정한 작업위치로 선박을 이동시킬 때까지는 문풀의 개구를 차폐하고, 선박이 일정한 위치로 도달될 경우에는 문풀의 개구를 용이하게 개방시킬 수 있도록 한 선박의 문풀 개폐장치에 관한 것이다.The present invention relates to a door pool opening and closing device of a ship, and more particularly, to increase the resistance of the hull due to the door pool, decrease in speed, increase horsepower, increase fuel consumption, damage to the hull, etc. The door pool opening and closing device of the ship to shield the opening of the door pool until moving the door, and to easily open the opening of the door pool when the ship reaches a fixed position.

국제적으로 급격하게 산업 및 공업이 발전함에 따라 석유와 같은 지구 자원의 사용량은 점차 증가하고 있으며, 이에 따라 원유의 안정적인 생산과 공급이 전지구적인 차원에서 대단히 중요한 문제로 떠오르고 있다.With the rapid development of industries and industries internationally, the use of global resources such as petroleum is gradually increasing, so that stable production and supply of crude oil is becoming a very important problem at the global level.

이와 같은 이유로, 최근에는 지금까지 경제성이 없어 무시되어 왔던 군소의 한계 유전(marginal field)이나 심해 유전의 개발이 경제성을 가지게 되었으며, 따라서 해저 채굴 기술의 발달과 더불어 이런 유전의 개발에 적합한 시추설비를 구비한 시추선이 개발되어 있다.For this reason, the development of marginal or deep sea oil fields, which have been neglected in recent years due to lack of economic efficiency, has become economical, and thus, along with the development of seabed mining technology, drilling facilities suitable for the development of such oil fields have been developed. Drilling ships have been developed.

즉, 종래의 해저 시추에는, 다른 예인선에 의해서만 항해가 가능하고 계류 장치를 이용하여 해상의 일점에 정박한 상태에서 해저 시추 작업을 하는 해저 시추 전용의 리그선(rig ship)이나 고정식 플랫홈이 주로 사용되었으나, 최근에는 첨단의 시추 장비를 탑재하고 자체의 동력으로 항해를 할 수 있도록 일반 선박과 동일한 형태로 제작된 소위, 시추선(FPSO, Floating Production Storage Offloading Vessels)이 개발되어 해저 시추에 사용되고 있다.That is, a conventional rig ship or a fixed platform exclusively used for subsea drilling, which can be sailed only by another tugboat and is anchored to one point of the sea using a mooring device, is used for conventional subsea drilling. However, recently, so-called drilling vessels (FPSO, Floating Production Storage Offloading Vessels), which are manufactured in the same form as general ships so that they can be sailed by their own power and equipped with advanced drilling equipment, have been developed and used for subsea drilling.

군소 유전 개발을 위해서는 그 위치를 자주 옮겨야 하는 작업 조건에 따라, 이런 시추선은 예인선 없이 자체의 동력으로 항해를 할 수 있도록 제작되어 있으며, 따라서 이와 같이 자체의 동력으로 항해하도록 설계된 시추선에 있어서는 최적의 항해 성능을 가지도록 건조되어야 한다.Depending on the working conditions that require frequent shifts in the development of small oil fields, these drilling vessels are designed to sail on their own power without tugboats, and thus are optimal for drilling vessels designed to sail on their own power. It must be dried to have performance.

시추선의 선체 중앙에는 시추 파이프를 해저 바닥으로 내려보내기 위한 대규모의 개구{소위, "문풀(Moon-Pool)"이라 함}가 형성되어 있다. 문풀은 시추선의용도 측면에서는 필수 불가결한 구조이지만, 정박, 항해 안정성이나 항해 성능의 측면에서는 매우 불리한 구조이다.In the center of the hull of the drilling vessel is a large opening (so-called "Moon-Pool") for sending the drilling pipe down to the sea floor. Moonpool is an indispensable structure for the purpose of drilling ships, but it is very disadvantageous in terms of anchoring, navigational stability and navigational performance.

즉, 문풀 내에 유입되어 있는 해수와 선체 외부의 해수의 상대적인 유동에 의해 발생되는 슬로싱(sloshing) 현상으로 인하여 시추선의 항해시에 저항 증가, 속도저하, 소요 마력 증가, 연료소모증가, 및 선체의 손상 등을 야기할 수 있다.In other words, due to the sloshing phenomenon caused by the relative flow of seawater entering the moon pool and the seawater outside the hull, the resistance increase, the speed decrease, the required horsepower increase, the fuel consumption increase, and the hull It may cause damage.

이에, 이러한 시추선은 조선소에서 건조된 후, 선주에게 전해지고 그 선주가 시추의 용도로 바다의 일정한 위치까지 시추선을 이동시킬 때까지는 상기의 문제를 일으키지 않도록 문풀의 개구를 일시적으로 차폐해야 할 필요가 있으며, 바다의 일정한 위치로 시추선을 이동시킨 후에는 별 어려움 없이 문풀의 개구를 다시 오픈시킬 필요가 있을 것이다.Therefore, it is necessary to temporarily shield the opening of the door pool so that the above-mentioned drilling ships are constructed at the shipyard and are conveyed to the ship owners and the ships are not caused the above problems until the ships are moved to a certain position in the sea for the purpose of drilling. After the drilling ship has been moved to a fixed position in the sea, it may be necessary to reopen the door pool without any difficulty.

본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 본 고안의 목적은, 문풀로 인한 선체의 저항 증가, 속도저하, 소요 마력 증가, 연료소모증가, 선체의 손상 등을 최소화하기 위해 일정한 작업위치로 선박을 이동시킬 때까지는 문풀의 개구를 차폐하고, 선박이 일정한 위치로 도달될 경우에는 문풀의 개구를 용이하게 개방시킬 수 있도록 한 선박의 문풀 개폐장치를 제공하는 것이다.The present invention has been devised to solve the above problems, the object of the present invention is to increase the resistance of the hull due to the door pool, speed reduction, increase the required horsepower, increase fuel consumption, damage to the hull, etc. The door pool opening and closing device is provided to shield the opening of the door pool until the ship is moved to a position, and to easily open the opening of the door pool when the ship is reached at a constant position.

이하에서는 첨부도면을 참조하여 본 고안의 바람직한 실시예에 대해서 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도 1에 도시된 바와 같이, 시추선이 될 수 있는 선박은, 그 위치에 따라 선박본체(10)의 앞쪽에 배치된 선수부(10a)와 뒤쪽에 배치된 선미부(10b), 그리고, 선수부(10a)와 선미부(10b) 사이에 형성된 문풀(12, Moon-Pool)을 갖는다.As shown in Figure 1, the ship that can be a drilling ship, according to the position of the bow portion 10a disposed in front of the ship body 10 and the stern portion 10b disposed behind, and the bow portion 10a ) And a moon-pool formed between the stern portion 10b.

문풀(12)은 선상(10c, Upper Deck)으로부터 선저(10d, Bottom)에 이르도록 높이방향을 따라 관통되어 예를 들어, 시추 파이프 등을 해저 바닥으로 내려보내는 통로로 이용된다.The door pool 12 penetrates along the height direction from the upper deck 10c to the bottom 10d and the bottom, and is used as a passage through which a drilling pipe or the like is lowered to the bottom of the sea floor.

전술한 바와 같이, 문풀(12)은 시추 파이프 등을 해저로 내려보내기 위해 필수불가결하게 마련해야 하지만, 조선소에서 선박이 건조된 후, 선주에게 전해지고 그 선주가 시추의 용도로 바다의 일정한 작업위치까지 선박을 이동시킬 때까지는 문풀(12)이라는 존재로 인해 선체의 저항 증가, 속도저하, 소요 마력 증가, 연료소모증가, 선체의 손상 등이 야기될 수 있다.As described above, the door pool 12 is indispensable to send drilling pipes and the like to the sea floor, but after the ship is built at the shipyard, it is conveyed to the ship owner and the ship ships to a certain working position in the sea for drilling purposes. Until the door is moved, the presence of the door pool 12 may cause an increase in resistance of the hull, a decrease in speed, an increase in horsepower required, an increase in fuel consumption, and damage to the hull.

이에, 본 고안에서는 문풀(12)을 갖는 선박이 일정한 작업위치로 이동될 때까지는 문풀(12)의 개구를 차폐하고 작업위치로 이동된 후에는 용이하게 문풀(12)의 개구를 개방시킬 수 있도록 한 문풀 개폐장치를 고안하고 있는 것이다.Accordingly, in the present invention, the vessel having the door pool 12 is shielded until the ship is moved to a constant work position, and after being moved to the work position, the opening of the door pool 12 can be easily opened. It is devising a door pull opening.

본 고안에 따른 문풀 개폐장치는, 도 2에 도시된 바와 같이, 적어도 일부분이 문풀(12) 내에 배치되어 문풀(12)의 개구를 차폐하는 차폐부재(21)와, 차폐부재(21)를 선박본체(10)에 착탈가능하게 결합 및 결합해제하는 결합부재(22)를 갖는다.In the door pool opening and closing device according to the present invention, as shown in FIG. 2, at least a portion of the door pool opening and closing device is disposed in the door pool 12 to shield the opening of the door pool 12, and the shielding member 21 is shipped. The coupling member 22 detachably engages and decouples the main body 10.

차폐부재(21)는 그 중량을 고려하여 철재질로 된 내부가 빈 프레임 등으로 제조할 수 있다. 그러나, 이 외에도 차폐부재(21)는 내부식성을 가져야함은 물론, 소정의 선박조건에 부합하는 조건을 가질 수 있는 구조물로 채용해야 할 것이다.The shielding member 21 may be manufactured as an empty frame made of steel in consideration of its weight. However, in addition to this, the shielding member 21 should not only have corrosion resistance, but also employ a structure that can have a condition that meets a predetermined ship condition.

결합부재(22)는, 통상적으로 볼트와 같은 것을 채용함으로써 차폐부재(21)의 결합 및 결합해제 작업을 용이하게 수행할 수 있도록 한다. 문풀(12)의 개구 연부면에는 반경방향 내측을 향해 연장된 플랜지부(24)가 형성되어 있다.Coupling member 22, it is possible to easily perform the engagement and disengagement operation of the shield member 21 by employing a bolt or the like. The flange portion 24 extending toward the radially inner side is formed on the opening edge surface of the door pool 12.

이에, 볼트와 같은 결합부재(22)를 차폐부재(21)의 일측으로 통과시켜 문풀(12)에 형성된 플랜지부(24)에 고정시킴으로써 차폐부재(21)를 용이하게 결합시킬 수 있다. 플랜지부(24)와 차폐부재(21) 사이에는 가스켓(25)이 마련되어 결합력을 높이는 한편, 결합 영역이 들뜨는 것을 저지하는 것이 유리하다.Accordingly, the shielding member 21 can be easily coupled by passing the coupling member 22 such as a bolt to one side of the shielding member 21 and fixing it to the flange portion 24 formed in the door pool 12. It is advantageous that a gasket 25 is provided between the flange portion 24 and the shielding member 21 to increase the bonding force, while preventing the joining region from lifting.

이처럼 결합부재(22)를 이용하여 문풀(12)에 차폐부재(21)를 결합시키더라도 문풀(12)과 차폐부재(21) 사이의 공간으로는 물이 침입할 수 있다. 물론, 물이 침입하더라도 선박을 운항하는 데에는 무리가 없으나, 물이 침입하는 만큼 선체의 저항 증가, 속도저하, 소요 마력 증가, 연료소모증가, 선체의 손상 등이 야기될 수 있는 바, 본 고안에서는 문풀(12)과 차폐부재(21) 사이의 공간으로 물이 침입하는 것을 저지하도록 워터실(26)을 장착하고 있다.As described above, even when the shield member 21 is coupled to the door pool 12 using the coupling member 22, water may enter the space between the door pool 12 and the shield member 21. Of course, even if water invades, there is no problem in operating the ship, but as the water invades, the resistance of the hull, the speed decrease, the required horsepower, the increase of fuel consumption, the damage of the hull can be caused. A water chamber 26 is mounted to prevent water from entering the space between the door pool 12 and the shield member 21.

워터실(26)은 선미부(10b)측에서 선수부(10a)측을 향해 문풀(12)의 외측부분 원주방향을 따라 연속적으로 설치되어 있다. 그러나, 워터실(26)이 마련되지 못한 문풀(12)과 차폐부재(21)의 내측부분은 물이 침입하는 공간이 발생할 수 있다.The water chamber 26 is continuously provided in the circumferential direction of the outer portion of the door pool 12 from the stern portion 10b side toward the bow portion 10a side. However, the inner space of the door pool 12 and the shield member 21 in which the water chamber 26 is not provided may generate a space where water enters.

따라서, 이 부분{소위, "버트라인(Butt Line)"이라 함}은 워터실(26)을 마련하기 전, 우선적으로 용접을 할 필요가 있는데, 차폐부재(21)를 문풀(12)에 부분적으로 용접하게 되면, 추후, 문풀(12)로부터 차폐부재(21)를 결합해제시키기가 곤란하다.Therefore, this part (so-called "Butt Line") needs to be welded first before the water chamber 26 is provided, and the shield member 21 is partially attached to the door pool 12. If it is welded with a metal, it is difficult to disengage the shield member 21 from the door pool 12 later.

이에, 본 고안에서는 버트라인을 직접 용접하지 않고 더블플레이트(27, Double Plate)로 취부용접함으로써 나중에 차폐부재(21)의 결합해제 작업을 용이하게 행할 수 있도록 하였다.Thus, in the present invention, by mounting welding with a double plate (27, Double Plate) without directly welding the butt line to facilitate the later release of the shield member (21).

이러한 구성에 의해, 차폐부재(21)의 일부분을 문풀(12)의 개구에 배치한 후, 결합부재(22)를 차폐부재(21)의 일측으로 통과시켜 문풀(12)에 형성된 플랜지부(24)에 고정시킨다.With this configuration, after a part of the shielding member 21 is disposed in the opening of the door pool 12, the flange portion 24 formed in the door pool 12 by passing the coupling member 22 to one side of the shielding member 21. ).

그런 다음, 버트라인을 더블플레이트(27, Double Plate)를 이용하여 취부용접하고, 선미부(10b)측에서 선수부(10a)측을 향해 문풀(12)의 외측부분 원주방향을 따라 연속적으로 워터실(26)을 설치함으로써 문풀(12)의 개구를 차폐한다.Then, the butt line is mounted and welded using a double plate (27, Double Plate), and the water seal continuously along the circumferential direction of the outer portion of the door pool 12 from the stern portion 10b side to the bow portion 10a side. By providing 26, the opening of the door pool 12 is shielded.

이러한 상태에서 선박을 바다의 일정한 작업위치로 이동시킨 다음에는, 전술한 반대로 문풀(12)의 개구를 개방하고, 문풀(12)을 통해 시추 파이프 등을 해저 바닥으로 내려보내는 작업을 행하면 된다.In this state, after moving the ship to a certain working position of the sea, the above-mentioned operation of opening the door of the door pool 12, and through the door pool 12 to send the drilling pipe or the like to the bottom of the sea floor.

이와 같이, 본 고안의 선박의 문풀 개폐장치에 의하면, 문풀(12)로 인한 선체의 저항 증가, 속도저하, 소요 마력 증가, 연료소모증가, 선체의 손상 등을 최소화하기 위해 일정한 작업위치로 선박을 이동시킬 때까지는 문풀(12)의 개구를 차폐하고, 선박이 일정한 위치로 도달될 경우에는 문풀(12)의 개구를 용이하게 개방시킬 수 있다.As described above, according to the door pool opening and closing device of the ship of the present invention, the ship is moved to a constant working position in order to minimize the increase of the hull resistance, the speed decrease, the required horsepower, the increase of fuel consumption, the damage of the hull, etc. due to the door pool 12. The opening of the door pool 12 can be shielded until it is moved, and the opening of the door pool 12 can be easily opened when the ship reaches a fixed position.

이상 설명한 바와 같이, 본 고안에 따르면, 문풀로 인한 선체의 저항 증가, 속도저하, 소요 마력 증가, 연료소모증가, 선체의 손상 등을 최소화하기 위해 일정한 작업위치로 선박을 이동시킬 때까지는 문풀의 개구를 차폐하고, 선박이 일정한 위치로 도달될 경우에는 문풀의 개구를 용이하게 개방시킬 수 있는 효과가 있다.As described above, according to the present invention, the opening of the door pool until the ship is moved to a certain working position in order to minimize the increase in the hull resistance, the speed decrease, the required horsepower, the fuel consumption, the damage of the hull, etc. due to the door pool When shielding the ship, when the ship reaches a fixed position there is an effect that can easily open the opening of the door pool.
