Description

선저 개구부의 밀폐장치{An equipment to close large opening located in the bottom of shuttle tanker like marine vessel}An equipment to close large opening located in the bottom of shuttle tanker like marine vessel}

본 발명은 선박의 선저하부에 개구부가 있는 셔틀 탱크류에 있어서 선저개구부의 밀폐장치에 관한 것으로, 더욱 상세하게는 선박의 하단에 형성되어 있는 원형의 개구부에 가운데와 외곽에 금속 재질의 링이 장착되고 상기 가운데와 외곽의 링은 텐션을 줄 수 있는 텐셔너로 연결되며 상기 텐셔너들의 사이에는 멤브레인류가 장착되는 스크린장치에 관한 것이다.The present invention relates to a sealing device for the bottom opening of a shuttle tank having an opening at the bottom of the ship, and more particularly, a metal ring is mounted at the center and the outer part of a circular opening formed at the bottom of the ship. The center and the outer ring are connected to a tensioner that can give tension, and the screen device is mounted between the tensioner membranes.

일반적으로 해양제선이라 하면 해양석유의 탐사, 시추, 생산, 처리, 저장 및 운송에 소요되는 선박들과 부대되는 파이프라인 부설선, 케이블부설선, 기중기선, 작업원 거주선, 보급품선, 예인선, 각종 부선 등 일체의 선박류를 총칭한다.In general, marine vessels include pipeline laying vessels, cable laying vessels, crane vessels, worker dwelling vessels, supply vessels, towing vessels, and ships involved in the exploration, drilling, production, processing, storage and transportation of offshore oil. All vessels such as various barges.

시추선이나 시추공에서 석유를 채취하는 선박은 선체로부터 파이프를 해저지하에 꽂아 놓고 있는 상태이기 때문에 위치유지가 가장 중요하다.Maintaining the position is most important because the oil-collecting vessels in drilling vessels or boreholes have pipes inserted from the hull undersea.

여러개의 앵커를 놓고 앵커 케이블에 걸리는 장력간의 형평에 의해 한 자리를 지키거나 또는 전방위 추진기를 여러대 놓아서 파랑이나 바람에 배가 밀리면 바로 추진기들이 자동적으로 작동하여 원위치로 되돌려 놓도록 자동화된 방법이 쓰이고 있다. 상기와 같은 장치를 다이나믹 포지셔닝 시스템(Dynamic Positioning System)이라고 한다. 모든 배들이 작업수행 목적의 특수 기계류를 나름대로 각기 정비하고 있는 점은 다르겠지만 조악한 천후조건, 즉 높은 파도와 빠른 조류, 강한 바람, 추운 기후 조건하에서 작업을 수행 할 수 있어야 한다는 일반조건은 같다. 이는 북해(North Sea) 유전에서 많은 시추와 생산활동이 이루어 지기 때문에 연유한 조건들이다. 배가 너무 많이 움직이지는 않고 한 자리에 있으면서 조류나 바람의 영향을 완충시키기 위해 한점의 회전점을 중심으로 돌아 주기만 하면 되는 FPSO(Floating Production and Storage Off-loading) 같은 배는 터릿 무링(Turret Mooring)장치를 쓴다.Automated methods are used to hold multiple anchors and maintain one position by the equilibrium between the tensions on the anchor cables, or to place multiple propellers in the blue or wind so that the propellers are automatically activated and returned to their original positions. . Such a device is called a dynamic positioning system. Although all ships have their own special machinery for the purpose of their work, the general conditions are that they must be able to work under harsh weather conditions: high waves, fast currents, strong winds and cold weather. This is due to the fact that there are many drilling and production activities in the North Sea oil field. Turret Mooring, such as Floating Production and Storage Off-loading (FPSO), where the ship is not moving too much and only needs to be centered around a single point of rotation to dampen the effects of algae or wind. Write the device.

즉, 선박의 아래 위로 관통하는 구멍을 뚫고 상기 구멍에 터릿(Turret)이라고 하는 돌쩌귀를 꽂은 다음 터릿(Turret)의 밑 부분에 앵커를 여러 개 매달아 설치하는 것이다.In other words, a hole penetrating the up and down of the ship, and inserting a burrow called a turret in the hole and then hanging several anchors in the bottom of the turret (Turret).

한편, 로딩 또는 언 로딩을 끝낸 후 셔틀탱크로 사용시 선저 개구부를 첨부된 도1에 도시된 바와 같이, 현재 밀폐하지 않고 운항하고 있어 저항 증가에 따른 선속 저하가 발생하며, 상기와 같이 선속의 저하에도 불구하고 효과적인 방법이 제시되지 못하고 있는 것이 현실이다.On the other hand, when using the shuttle tank after loading or unloading, as shown in Figure 1 attached to the bottom opening, it is currently operating without sealing, the vessel speed decreases due to the increase in resistance, and even if the vessel speed decrease as described above Nevertheless, no effective method has been suggested.

본 발명은 상술한 문제점을 해결하기 위하여, 선박의 선저하부에 개구부가 있는 셔틀 탱크류에 있어서, 선저개구부의 밀폐장치에 관한 것으로 선저 개구부를 효과적으로 밀폐시켜 선박의 속도저감을 줄이는 것을 목적으로 한다.In order to solve the above-mentioned problems, the present invention relates to a shutoff device having an opening at the bottom of a ship, and more particularly to a sealing device of the bottom opening, and to effectively reduce the speed of the ship by sealing the bottom opening.

상기 기술한 목적을 달성하기 위하여, 서브머지드 터릿 언로딩(Submerged Turret Unloading)을 쓰는 셔틀 탱크류(Shuttle Tanker)에 있어, 외각에 선체와 스크린장치를 체결하는 패스닝이 장착되어 있는 제1링이 형성되어 있고, 중심에는 접힘구조로 인장과 압축작용을 하는 텐셔너로 상기 제1링과 연결된 제2링이 형성되고, 상기 제1링 및 제2링의 사이에는 주름식의 멤브레인으로 구성되어 있는 것을특징으로 하는 선저개구부의 밀폐장치를 제공한다.In order to achieve the above object, in a Shuttle Tanker using Submerged Turret Unloading, a first ring is provided with a fastening for fastening hull and screen device to the outer shell. The second ring is connected to the first ring by a tensioner for tensioning and compressing with a folded structure at the center thereof, and a corrugated membrane is formed between the first ring and the second ring. Provided is a sealing device for the bottom opening, characterized in that.

본 발명은 선박의 선저하부에 개구부가 있는 셔틀 탱크류에 있어서 선저개구부의 밀폐방법에 관한 것으로, 더욱 상세하게는 선박의 하단에 형성되어 있는 원형의 개구부에 가운데와 외곽에 스틸재질의 링이 장착되고 상기 가운데와 외곽의 링은 텐션을 줄 수 있는 텐셔너로 연결되며 상기 텐셔너들의 사이에는 멤브레인류가 장착되는 스크린장치에 관한 것이다.The present invention relates to a method for sealing a bottom opening of a shuttle tank having an opening at the bottom of a ship, and more particularly, a ring made of steel at the center and the outside of a circular opening formed at the bottom of the ship. The center and the outer ring are connected to a tensioner that can give tension, and the screen device is mounted between the tensioner membranes.

이하 첨부된 도면을 참조하여 본 발명의 구성과 바람직한 일 실시예를 구체적으로 설명하면 다음과 같다.Hereinafter, a configuration and a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

본 발명인 스크린 장치의 평면도를 도시한 도2에서 알 수 있듯이, 외각에 선체(10)와 스크린장치(90)를 체결하는 패스닝(40)이 장착되어 있는 제1링(50)이 형성되어 있고, 중심에는 접힘구조로 인장과 압축작용을 하는 텐셔너(70)로 상기 제1링(50)과 연결된 제2링(60)이 형성되고, 상기 제1링(50) 및 제2링(60)의 사이에는 주름식의 멤브레인(80)으로 구성되어 있는 구조이다.As shown in Fig. 2 showing a plan view of the screen device of the present invention, a first ring 50 having a fastening 40 for fastening the hull 10 and the screen device 90 to the outer shell is formed. In the center, a second ring 60 connected to the first ring 50 is formed by a tensioner 70 having a tensioning and compression action in a folded structure, and the first ring 50 and the second ring 60 are formed. In between, the structure is composed of a corrugated membrane (80).

그리고 본 발명인 스크린장치가 장착된 선박의 선저개구부의 측단면도는 도3에 도시된 바와 같으며, 텐셔너(70)에 의해 멤브레인(80)이 평평하게 펴지게 되어 이것이 선저개구부(20)를 부분적으로 밀폐하는 작용을 하게 된다.And the side cross-sectional view of the bottom opening of the ship equipped with the screen device of the present invention as shown in Figure 3, the membrane 80 is flattened by the tensioner 70, which partially opens the bottom opening 20 It will act as a seal.

또한 본 발명의 작동방법으로 로딩중의 단면을 도시한 도4와 로딩후의 단면을 도시한 도5에서 알 수 있듯이, 선박의 데크위에 위치한 윈치에 의해 끌어올려지는 터릿(30)의 상단부(35)가 스크린장치(90)의 중심부에 형성되어 있는 제2링(60)을 걸고 상방향으로 올라가는 작동을 하게 되며, 상기 스크린장치(90)의 멤브레인(80)은 접힘구조로 신축성이 있고 부피가 적으므로 최종적으로 선박의 선체(10)와 터릿(30)사이에 위치하게 된다.In addition, as can be seen in Figure 4 showing the cross section during loading and Figure 5 showing the cross section after loading in the operating method of the present invention, the upper end 35 of the turret 30 is pulled by the winch located on the deck of the ship The second ring 60 formed in the center of the screen device 90 to the upward operation is performed, the membrane 80 of the screen device 90 is folded and has a flexible structure and a small volume Therefore, it is finally located between the hull 10 and the turret 30 of the ship.

상술한 바와 같이 서브머지드 터릿 언로딩(Submerged Turret Unloading)을 쓰는 셔틀 탱커류(Shuttle Tanker)의 경우 선저에 대형 개구부가 있으며, 적재 또는 하역이 끝난후 다시 운항할 경우에도 선저 개구부를 밀폐시킬 수 있기 때문에 이로 인한 선박의 속도 저감을 줄일 수 있게 되었고 결과적으로 연료손실 및 소요되는 파워의 증가를 막을 수 있게 되어 경제적으로 운항할 수 있는 효과가 있다.As described above, the Shuttle Tanker using Submerged Turret Unloading has a large opening at the bottom, and the bottom opening can be closed even when the ship is operated again after loading or unloading. As a result, it is possible to reduce the speed reduction of the vessel, and as a result, it is possible to prevent the increase of fuel loss and the required power, and thus it is possible to operate economically.
