일반적으로 횡동요 저감장치라 함은 선박의 횡동요를 줄여 선박이 안정된 자세를 유지할 수 있도록 하는 장치로써, 대표적인 횡동요 저감장치로는 빌지킬(Bilge Keel), 핀안정기(Fing Stabilizer), 횡요 감요 수조(Anti-Rolling Tank) 등이 있다.In general, the lateral attenuation reduction device is a device that reduces the lateral agitation of a ship to maintain a stable posture. Representative lateral attenuation devices are a bilge keel, a fin stabilizer, and a lateral yoke reduction. Anti-Rolling Tank, etc.

최근에는 질량체를 선박의 횡방향으로 이동시켜 선박의 횡동요를 저감시키는 기술에 대한 연구가 이루어지고 있다.In recent years, research has been made on a technique for reducing the lateral fluctuation of the ship by moving the mass in the transverse direction of the ship.

예컨대, 한국공개특허 제2005-0109809호에는 곡선레일 혹은 스프링을 이용한 이동질량과 감쇠력제어기를 사용하여 해상에서 작업을 하거나 항해하는 부유식 해양구조물과 선박의 횡동요를 효과적으로 감쇠할 수 있도록 한 질량이동형 횡동요 감쇠장치가 개시되어 있고, 한국공개특허 제2006-0014191호에는 선박의 일 영역에 횡방향으로 배치되는 적어도 하나의 지지가이드와, 상기 선박의 횡동요에 대해 역위상으로 상기 지지가이드를 따라 왕복 이동하는 적어도 하나의 가동질량체와, 상기가동질량체의 양측에서 상기 가동질량체를 상기 이동방향으로 탄성 가압하는 적어도 한 쌍의 스프링을 갖는 저감장치본체를 갖는 선박용 횡동요 저감장치가 개시되어 있다.For example, Korean Patent Laid-Open Publication No. 2005-0109809 uses a mass of a moving rail and a damping force controller using a curved rail or a spring to effectively attenuate the lateral fluctuations of floating marine structures and vessels that work or sail at sea.

본 발명에 따른 질량이동형 횡동요 저감장치는 횡동요 저감유닛(120)이 다수 개로 구성되고, 다수 개의 횡동요 저감유닛(120)이 선박의 길이방향으로 나란하게 배치되어 대형선박의 횡동요를 저감시키도록 구성될 수 있다.In the mass transfer type lateral attenuation reduction device according to the present invention, a plurality of lateral attenuation reduction units 120 are provided, and a plurality of lateral attenuation reduction units 120 are arranged side by side in the longitudinal direction of the ship to reduce lateral agitation of a large vessel. It can be configured to.

이때 각각의 횡동요 저감유닛(120)은 제어부(130)에 의해 개별적으로 제어되며, 제어부(130)는 해당 선박의 운항 시의 배수량을 계측해서 운항 시 횡동요 저감을 위해 요구되는 이동질량을 결정하고, 결정된 값에 상응하는 수개의 횡동요 저감유닛(120)들을 선택하여 제어하게 된다.At this time, each lateral shake reduction unit 120 is individually controlled by the control unit 130, the control unit 130 measures the amount of displacement during the operation of the vessel to determine the moving mass required for reducing lateral fluctuations during operation Then, several lateral fluctuation reduction units 120 corresponding to the determined value are selected and controlled.

한편 상기 횡동요 저감유닛(120)을 도 1에 도시된 바와 같이, 선박의 이중저(double botttom)에 설치하게 되면, 횡동요 저감유닛(120)의 설치로 인해 화물 적재 공간이 손실되는 것을 방지할 수 있게 된다.
Meanwhile, as shown in FIG. 1, when the lateral fluctuation reduction unit 120 is installed in a double botttom of a vessel, the load loading space is prevented from being lost due to the installation of the lateral fluctuation reduction unit 120. You can do it.

상기와 같이 구성된 질량이동형 횡동요 감소장치의 작용효과에 대해 설명하면 다음과 같다.Referring to the effect of the mass transfer type lateral fluctuation reduction device configured as described above are as follows.

선박의 정박 시 또는 운항 시 선체가 어느 한쪽 측방으로 기울어지게 되면, 횡동요 감지센서(110)를 선체가 기울어진 방향과 크기를 감지하게 되고, 횡동요 감지센서(110)에 의해 감지되는 횡동요 정보는 제어부(130)로 전달된다.When the hull is inclined to either side at the time of anchoring or operation of the vessel, the horizontal shaking sensor 110 detects the direction and size of the hull tilted, the horizontal shaking detected by the horizontal shaking sensor 110 The information is transferred to the controller 130.

한편 제어부(130)는 화물 적재량에 따른 해당 선박의 선수 선미에 부착된 수위계를 이용해서 배수량 정보를 계산하고 해당 선박의 배수량을 고려하여 적절한 개수의 횡동요 저감유닛(120)을 선택하게 된다. 이때 상호 인접한 수개의 횡동요 저감유닛들이 선택될 수도 있고, 소정 간격을 두고 이격된 수개의 횡동요 저감유닛들이 선택될 수도 있으며, 선박의 배수량이 클수록 보다 많은 수의 횡동요 저감유닛들이 선택된다.On the other hand, the control unit 130 calculates the drainage information by using the water gauge attached to the stern of the vessel according to the cargo load, and selects the appropriate number of lateral fluctuation reduction unit 120 in consideration of the drainage of the vessel. At this time, several adjacent roll-attenuation reduction units may be selected, or several roll-attenuation reduction units spaced apart from each other by a predetermined interval may be selected, and a larger number of roll-attenuation reduction units are selected as the displacement of the ship is larger.

해당 선박의 배수량에 따른 횡동요 저감유닛(120)들이 선택되고, 횡동요 감지센서(110)로부터 횡동요 정보가 전달되면, 제어부(130)는 각각의 횡동요 저감유닛(120)에 구비된 대차(122)가 횡동요 저감을 위해 요구되는 방향(선체가 기울어지는 방향과 반대되는 방향)으로 대차(122)가 이동하도록 구동유닛(124)을 제어하게 된다. 이때 대차(122)의 이동거리와 속도는 횡동요의 크기와 주기를 고려하여 결정된다.When the roll shaking reduction unit 120 is selected according to the discharge amount of the vessel, and the roll shaking information is transmitted from the roll shaking sensor 110, the controller 130 is provided with the rolls of each roll shaking reducing unit 120. The driving unit 124 is controlled so that the cart 122 moves in the direction required to reduce the lateral fluctuation (the direction opposite to the direction in which the hull is inclined). At this time, the moving distance and the speed of the trolley 122 are determined in consideration of the magnitude and the period of the transverse shaking.

한편 상기 각각의 대차(122)에는 구동유닛(124)이 설치되어 각각의 대차(122)는 자체 구동을 통해 신속한 이동이 가능하게 되므로, 횡동요의 저감을 위해 요구되는 위치로 질량체(122a)를 빠르고 정확하게 이동시킬 수 있으며, 이로 인해 횡동요에 대해서 보다 신속하고 정확한 대응이 가능하게 된다.
On the other hand, each of the trolley 122, the drive unit 124 is installed so that each of the trolley 122 can be moved quickly through its own drive, the mass body 122a to the position required for reducing the lateral fluctuations It can be moved quickly and accurately, which allows for a faster and more accurate response to lateral fluctuations.
