Description

해양 구조물의 위치제어장치Position Control System of Offshore Structures
본 발명은 해양 구조물의 위치제어장치에 관한 것으로, 보다 구체적으로 설명하면, 해양 환경 또는 조건에 따라 해수면에 떠 있는 해양 구조물의 위치를 제어할 수 있는 해양 구조물의 위치제어장치에 관한 것이다.The present invention relates to a position control apparatus for an offshore structure, and more specifically, to a position control apparatus for an offshore structure capable of controlling the position of an offshore structure floating on the sea surface according to the marine environment or conditions.
일반적으로, 해양 구조물은 해수면 위에 떠 있는 상태로 계류될 수 있는 것으로, 기능, 구조, 계류방식에 따라 다양한 종류로 분류된다.In general, marine structures can be moored floating above sea level, and are classified into various types according to their function, structure, and mooring method.
예를 들면, 해양 구조물은 SEMI(Semi-Submersible), TLP(Tensioned Leg Platform), SPAR, FPSO(Floating, Production, Storage and Off-loding), FSRU 또는 시추용 리그(Rig) 등으로 칭해지는 많은 종류의 해양 구조물이 있다.For example, offshore structures have many types, including semi-submersible (SEM), tensioned leg platform (TLP), SPAR, floating, production, storage and off-loding (FPSO), FSRU, or drilling rigs. There is a marine structure.
이러한, 해양 구조물은 터릿이나 요크 무어링과 같은 일점 계류에 의해 계류된 채 사용될 수 있다. 이와 같은, 일점 계류 방식은 바람, 조류, 및 파랑과 같은 환경 외력의 방향이 자주 변하는 해역에서 운용되는 부유식 구조물에 적용되는 계류방식이다.These offshore structures can be used while mooring by one point moorings such as turrets or yoke moorings. This one-point mooring method is a mooring method applied to a floating structure operating in a sea area where the direction of environmental external force such as wind, tidal current, and blue wave changes frequently.
해양 구조물에는 외부 환경에 따라 다양한 외력이 가해진다. 외부로부터 가해지는 외력은 예들 들면, 바람, 조류 및 파랑(파도) 등을 들 수 있으며, 계류된 상태의 해양 구조물은 외부로부터 다양한 외력의 크기가 최소가 되는 방향으로 자연스럽게 선수각이 안정화된다.Offshore structures are subject to various external forces, depending on the external environment. Examples of the external force applied from the outside include wind, tidal currents and waves (waves), and the marine structure in the mooring state stabilizes the bow angle naturally in a direction in which various external forces are minimized from the outside.
그러나, 바람 및 조류가 해양 구조물에 작용하는 방향과, 파랑(파도)이 해양 구조물에 작용하는 방향이 서로 다를 경우에는, 선수각이 안정된 상태에서 파랑이 선체의 정면이 아닌 측면에 작용하는 경우가 발생할 수 있다. 이때, 파고가 높다면 선체의 운동, 특히 선체가 좌우로 흔들리는 선수동요(roll motion)가 커지게 된다.However, if the direction of wind and tidal current acting on the marine structure and the direction of wave (wave) acting on the marine structure are different from each other, the wave acts on the side of the hull instead of the front of the hull with the bow angle stabilized. May occur. At this time, if the crest is high, the movement of the hull, in particular, the roll motion of the hull swinging from side to side becomes large.
즉, 선수동요가 지나치게 커지게 되면, 해양 구조물에 설치된 각종 설비들의 가동을 어렵게 만들거나, 저장탱크내에 심각한 슬로싱 현상이 발생될 수 있으므로 상황에 따라 선수각을 인위적으로 제어할 필요가 있다. 여기서, 슬로싱이란, 선박과 같은 부유체가 다양한 해상 상태에서 운동할 때 저장탱크 내에 수용된 액체 상태의 물질이 유동하는 현상을 말하는 것으로, 슬로싱에 의해 저장탱크의 벽면은 심한 충격을 받게된다.That is, if the bow movement is too large, it is difficult to operate the various equipment installed in the offshore structure, or serious sloshing phenomenon may occur in the storage tank, it is necessary to artificially control the bow angle according to the situation. Here, sloshing refers to a phenomenon in which a liquid substance contained in a storage tank flows when a floating body such as a ship moves in various sea conditions, and the wall surface of the storage tank is severely impacted by sloshing.
아울러, 전술한 바와 같은 계류방식은 수심이 깊은 곳에서는 가능하지만, 수심이 낮은 곳에서는 적용할 수 없는 문제점이 있다.In addition, the mooring method as described above is possible in a deep depth, but there is a problem that cannot be applied in a low depth.
따라서, 본 발명은 전술한 문제점을 해결하고자 하는 것으로, 해양 환경 또는 조건에 따라 해양 구조물의 위치를 제어할 수 있는 해양 구조물의 위치제어장치를 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a position control apparatus for an offshore structure capable of controlling the position of the offshore structure according to the offshore environment or conditions.
또한, 수심이 낮은 곳에서도 해양 구조물의 위치를 제어할 수 있는 해양 구조물의 위치제어장치를 제공하는 것을 목적으로 한다.In addition, an object of the present invention is to provide a position control apparatus for an offshore structure that can control the position of an offshore structure even in a low water depth.

도 1 내지 도 6을 참조하면, 본 발명의 일실시예에 따른 해양 구조물의 위치제어장치(10)는 해양에서 계류될 수 있는 해양 구조물(1)에 설치되며, 지지프레임(12), 탄성체(14), 포일(16)을 포함하여 구성된다.1 to 6, the position control apparatus 10 of the marine structure according to an embodiment of the present invention is installed in the marine structure (1) that can be moored in the ocean, the support frame 12, the elastic body ( 14), comprising a foil (16).
지지프레임(12)은 다수개의 프레임을 결합하여 사각형상으로 이루어지며, 해양 구조물(1)의 둘레방향을 따라 일정간격 이격하여 복수개가 설치된다. Support frame 12 is formed in a rectangular shape by combining a plurality of frames, a plurality of spaced apart a predetermined interval along the circumferential direction of the marine structure (1) is installed.
여기서, 지지프레임(12)의 일측면 길이방향 소정 위치에는 전력생성수단(20)이 마련되고, 타측면 길이방향 소정 위치에는 구동수단(30)이 마련되며, 구동수단(30)은 전력생성수단(20)으로부터 생성된 전력을 공급받아 후술하는 포일(16)을 구동시킨다.Here, the power generating means 20 is provided at one side longitudinally predetermined position of the support frame 12, the drive means 30 is provided at the other predetermined position in the longitudinal direction of the other side, the driving means 30 is the power generating means The foil generated from 20 is supplied to drive the foil 16 to be described later.
전력생성수단(20)은 일측면이 후술하는 탄성체(14)에 구비된 연결바(14a)의 일단과 결합되는 기어박스(22)와, 기어박스(22)에 구비된 회전축(22a)에 결합되어 회전축(22a)의 회전력을 이용하여 전력을 생산하는 발전기(24)로 구성된다.The power generating means 20 is coupled to the gearbox 22 coupled to one end of the connection bar 14a provided in the elastic body 14, one side of which will be described later, and the rotating shaft 22a provided in the gearbox 22. It is composed of a generator 24 for producing electric power by using the rotational force of the rotary shaft (22a).
여기서, 기어박스(22)는 후술하는 포일(16)이 파도에 의해 상하운동을 회전운동으로 변환시킬 수 있는 구조로 이루어지는 것이 바람직하다.Here, the gear box 22 is preferably made of a structure in which the foil 16, which will be described later, can convert the vertical motion into the rotary motion by the waves.
즉, 기어박스(22)의 내부에는 회전축(22a)에 일단이 결합되며 타단에 플라이휠(26a)이 구비된 크랭크축(26)과, 일단이 플라이휠(26a)에 결합되고 타단이 탄성체(14)에 구비된 연결바(14a)에 결합된 링크부재(28)가 구비된다.That is, one end of the gearbox 22 is coupled to the rotating shaft 22a and the other end of the crankshaft 26 having the flywheel 26a, and one end of the flywheel 26a and the other end of the elastic body 14.

구동수단(30)은 해양의 환경 또는 조건이 악화되어 바람 또는 파도(파랑)이 심할 경우에 후술하는 포일(16)에서 발생되는 운동 에너지로는 해양 구조물(1)의 위치가 제어되지 않을 경우 포일(16)을 강제 구동시키는 역할을 한다.The driving means 30 is a foil when the position of the marine structure 1 is not controlled by the kinetic energy generated from the foil 16 to be described later, when the marine environment or conditions are deteriorated and the wind or the wave (blue) is severe. It serves to force (16).
여기서, 해상 구조물(1)의 위치는 해상 구조물(1)에 구비된 GPS(미도시)로부터 위치를 제공받아 위치를 제어하게 된다.Here, the position of the marine structure 1 is controlled by receiving a position from a GPS (not shown) provided in the marine structure (1).
이러한, 구동수단(30)은 일측면이 후술하는 탄성체(14)에 구비된 연결바(14a)의 타단과 결합되는 기어박스(32)와, 기어박스(32)에 구비된 회전축(32a)에 결합된 감속기어박스(34)와, 감속기어박스(34)와 연결된 구동모터(39)로 구성된다.The driving means 30 has a gear box 32 coupled to the other end of the connecting bar 14a provided at the elastic body 14, which is described later, and a rotation shaft 32a provided at the gear box 32. Combination of the reduction gear box 34, and the drive motor 39 is connected to the reduction gear box (34).
여기서, 기어박스(32)의 구성은 전술한 전력생성수단(20)의 기어박스(22)와 동일한 구성으로 이루어지므로 상세한 설명은 생략하기로 한다.Here, since the configuration of the gearbox 32 is made of the same configuration as the gearbox 22 of the power generation means 20 described above, a detailed description thereof will be omitted.
아울러, 회전축(32a)의 소정 위치에는 선택적으로 동력의 전달을 차단할 수 있는 클러치수단(33)이 마련되는 것이 바람직하다.In addition, it is preferable that the clutch means 33 is provided at a predetermined position of the rotation shaft 32a to selectively block the transmission of power.
전술한 바와 같은 구성으로 이루어진 구동수단(30)의 작동은 구동모터(39)가 전력생성수단(20)으로부터 전력을 공급받아 구동하게 되면, 기어박스(32)에 구비된 회전축(32a)이 회전을 하게 되고, 회전축(32a)이 회전하면 회전축(32a)에 일단이 결합되고 타단에 플라이휠(36a)이 구비된 크랭크축(36)이 회전을 하게 됨으로써 일단이 플라이휠(36a)에 결합되고 타단이 탄성체(14)에 구비된 연결바(14a)에 결합된 링크부재(38)가 작동하게 된다.Operation of the driving means 30 having the configuration as described above is driven when the driving motor 39 is supplied with power from the power generating means 20, the rotation shaft 32a provided in the gear box 32 is rotated When the rotation shaft 32a rotates, one end is coupled to the rotation shaft 32a, and the other end thereof is coupled to the flywheel 36a so that the crank shaft 36 with the flywheel 36a provided on the other end rotates. The link member 38 coupled to the connecting bar 14a provided in the elastic body 14 is operated.

Subsequently, when the link member 38 is operated, the connecting bar 14a moves up and down along the guide groove 32b formed on one side of the gear box 32 in association with the operation of the link member 38. As the connecting bar 14a is vertically rotated, the elastic body 14 and the foil 16 coupled to the elastic body 14 are also vertically rotated together.
탄성체(14)는 지지프레임(12)의 내부 일측에 일단이 결합되며, 이러한, 탄성체(14)의 폭 방향 소정 위치에는 탄성체(14)의 길이방향을 따라 연결바(14a)가 구비된다.One end of the elastic body 14 is coupled to an inner side of the support frame 12, and a connection bar 14a is provided along a length direction of the elastic body 14 at a predetermined position in the width direction of the elastic body 14.

The foil 16 generates the kinetic energy in a direction opposite to the direction in which the wave kinetic energy acts.
즉, 포일(16)이 파도의 영향을 받아 회동운동을 함으로써 운동 에너지를 생성하기 때문에 해상 구조물(1)의 위치가 파도의 영향을 받아 위치가 변경되지 않도록 한다.That is, since the foil 16 generates the kinetic energy by the rotational movement under the influence of the wave, the position of the offshore structure 1 is not changed by the wave.
여기서, 포일(16)의 상부면과 하부면에는 복수개의 돌출부(16a)가 포일(16)의 길이방향을 따라 형성될 수 있는데, 이 복수개의 돌출부(16a)는 포일(16)의 표면에 난류를 발생시켜 추진력과 양력을 얻을 수 있도록 한다. 즉, 포일(16)이 파도의 영향을 받아 회동운동할 때 발생되는 운동 에너지를 증가시킨다.Here, a plurality of protrusions 16a may be formed along the longitudinal direction of the foil 16 on the upper and lower surfaces of the foil 16, which are turbulent on the surface of the foil 16. To generate propulsion and lift. That is, the kinetic energy generated when the foil 16 rotates under the influence of the wave increases.
아울러, 포일(16)의 상부면과 하부면의 가장자리에는 즉, 전술한 복수개의 돌출부(16a)와 인접한 위치에는 포일(16)의 길이방향을 따라 복수개의 딤플(16b) 또는 돌기(미도시)를 형성하는 것도 가능하다.In addition, a plurality of dimples 16b or protrusions (not shown) are formed at edges of the upper and lower surfaces of the foil 16, that is, at positions adjacent to the plurality of protrusions 16a described above along the longitudinal direction of the foil 16. It is also possible to form a.
또한, 도면에 도시하진 않았지만, 포일(16)의 상부면과 하부면에 형성된 복수개의 돌출부(16a) 대신에 포일(16)의 상부면과 하부면 전체면에 걸쳐 딤플(16b) 또는 돌기(미도시)를 형성하는 것도 가능하다.In addition, although not shown in the drawings, instead of the plurality of protrusions 16a formed on the upper and lower surfaces of the foil 16, the dimples 16b or projections (not shown) are applied over the entire upper and lower surfaces of the foil 16. It is also possible to form a).
