Description

해수 분사장치를 갖춘 해양 구조물 {MARINE STRUCTURE HAVING SEA WATER NOZZZLES}[0001] MARINE STRUCTURE HAVING SEA WATER NOZZZLES WITH SEAWATER INJECTION DEVICE [0002]

본 발명은 해수 분사장치를 갖춘 해양 구조물에 관한 것으로서, 더욱 상세하게는 해양 구조물에 설치된 LNG 재기화 장치용 해수의 흡입구와 배출구 사이에 배치되어 흡입되는 해수와 배출되는 해수를 서로 섞이지 않도록 하기 위한 해수 분사장치를 갖춘 해양 구조물에 관한 것이다.The present invention relates to an offshore structure having a seawater injection device. More particularly, the present invention relates to an offshore structure having a seawater injection device, And an offshore structure having an injection device.

천연가스는, 육상 또는 해상의 가스배관을 통해 가스 상태로 운반되거나, 또는 액화된 액화천연가스(LNG)의 상태로 LNG 수송선에 저장된 채 원거리의 소비처로 운반된다. LNG는 천연가스를 극저온으로 냉각하여 얻어지는 것으로 가스 상태의 천연가스일 때보다 그 부피가 대략 1/600로 줄어들므로 해상을 통한 원거리 운반에 매우 적합하다.Natural gas is transported in a gaseous state through land or sea gas pipelines, or is transported to a remote location where it is stored in an LNG carrier in the form of liquefied natural gas (LNG). LNG is obtained by cooling the natural gas at a cryogenic temperature, and its volume is reduced to about 1/600 of that of natural gas, which makes it very suitable for long distance transportation through the sea.

LNG 운반선에 의해 목적지까지 원거리에 걸쳐서 수송되어 온 LNG는, LNG 부유식 저장 및 재기화 장치(Floating Storage and Regasification Unit, FSRU) 또는 육상의 하역 터미널을 거치면서 재기화되어 소비처로 공급된다.LNG transported over a long distance to the destination by the LNG carrier is regenerated through the LNG floating storage and regasification unit (FSRU) or the offshore terminal and supplied to the consumer.

LNG FSRU는 육상으로부터 멀리 떨어진 해상에서 LNG 운반선으로부터 하역되는 LNG를 저장탱크에 저장한 후 필요에 따라 저장탱크 내의 LNG를 기화시켜 육상 수요처에 공급하는 해양 구조물이다. 최근에는 LNG의 운반과 재기화를 함께 수행할 수 있도록 LNG 운반선에 재기화 장치를 탑재한 LNG RV(Regasification Vessel)가 개발되어 있기도 하다.LNG FSRU is an offshore structure that stores LNG unloaded from an LNG carrier in offshore offshore and stores it in a storage tank, and then supplies LNG in the storage tank to the customer. In recent years, LNG RV (Regasification Vessel) has been developed, which is equipped with a regeneration device in an LNG carrier so that the LNG carrier can be transported and regasified together.

이와 같은 LNG FSRU, LNG RV 등의 해양 구조물에는 LNG를 재기화시키는 장치가 설치되어 있는데, 일반적으로 LNG 재기화 장치는 해수를 이용하여 LNG를 재기화시킨다.The LNG FSRU, LNG RV, and other offshore structures are equipped with a device for regeneration of LNG. In general, the LNG regasification system reuses the LNG using seawater.

이를 위해 해양 구조물의 선체에는, 재기화용 해수를 선체 내로 흡입하기 위한 흡입구와, LNG를 가열하여 재기화시키면서 열을 빼앗겨 냉각된 해수를 선체 외부로 배출하기 위한 배출구가 형성되어 있다. 배출된 해수는 온도가 낮으므로 배출된 해수가 재유입될 경우 재기화 효율이 떨어지게 된다. 종래에는, 배출구를 통해 배출된 해수가 흡입구를 통해 다시 흡입되는 것을 방지하기 위해, 배출구에서 배출되는 해수의 흐름이 흡입구의 반대쪽을 향하도록 하였지만, 배출된 해수의 재유입을 완전히 막지 못하는 문제가 있었다.To this end, the hull of the offshore structure is provided with an intake port for sucking the seawater for regasification into the hull, and an exhaust port for discharging the cooled seawater to the outside of the hull by absorbing heat while regenerating the LNG. Since the discharged seawater has a low temperature, the re-circulation efficiency becomes low when the discharged seawater is re-introduced. Conventionally, although the flow of the seawater discharged from the discharge port is directed toward the opposite side of the suction port in order to prevent the seawater discharged through the discharge port from being sucked again through the suction port, there is a problem that the re-inflow of the discharged seawater can not be completely prevented .

이러한 종래의 문제점들을 해결하기 위한 본 발명은, 해양 구조물에 설치된 LNG 재기화 장치용 해수의 흡입구와 배출구 사이에 배치되어 흡입되는 해수와 배출되는 해수를 서로 섞이지 않도록 하기 위한 해수 분사장치를 갖춘 해양 구조물을 제공하고자 하는 것이다.In order to solve such conventional problems, the present invention provides a marine structure having a seawater injection device disposed between an inlet and an outlet of seawater for an LNG regeneration device installed in an offshore structure, .

본 발명의 일 측면에 따르면, 액화가스를 재기화시키기 위해 액화가스를 가열할 때 열원으로서 해수를 사용하는 재기화 장치를 포함하는 해양 구조물로서, 해수를 선체 내로 흡입하기 위한 흡입구와; 액화가스와의 열교환을 통해 냉각된 해수를 선체 외부로 배출시키기 위한 배출구와; 해수를 분사시켜 상기 흡입구 주위의 해수와 상기 배출구 주위의 해수를 서로 분리시킬 수 있는 분사장치; 를 포함하는 것을 특징으로 하는 해양 구조물이 제공된다.According to an aspect of the present invention, there is provided an offshore structure including a regeneration device that uses seawater as a heat source when heating liquefied gas to regenerate liquefied gas, comprising: an inlet for sucking seawater into the hull; An outlet for discharging the cooled seawater to the outside of the ship by heat exchange with the liquefied gas; An injector capable of spraying seawater to separate seawater around the inlet and seawater around the outlet; The present invention provides an offshore structure comprising:

이하, 본 발명의 바람직한 실시예에 따른 해수 분사장치를 갖춘 해양 구조물을, 도면을 참조하여 상세하게 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a marine structure having a seawater injection device according to a preferred embodiment of the present invention will be described in detail with reference to the drawings.

본 명세서에서 해양 구조물이란, LNG를 재기화시키는 장치가 설치되어 있으며 이 재기화 장치에서 LNG를 가열하여 기화시키는 열원으로서 해수를 사용하는 LNG RV 등과 같은 선박과, LNG FSRU 등과 같은 해상 플랜트를 모두 포함하는 개념이다.In this specification, the term "offshore structure" means an apparatus for re-igniting LNG, including a vessel such as an LNG RV that uses seawater as a heat source for heating and vaporizing LNG in the regasification apparatus and a marine plant such as an LNG FSRU Concept.

도 1 및 도 2에는 본 발명에 따른 해양 구조물의 주요부 측면도 및 저면도가 도시되어 있다.1 and 2 show a side view and a bottom view of a main portion of an offshore structure according to the present invention.

본 발명에 따른 해양 구조물은, 종래와 마찬가지로, LNG의 재기화시 열원으로서 사용하기 위한 해수를 선체 내로 흡입하기 위한 흡입구(3)와, LNG와의 열교환을 통해 냉각된 해수를 선체 외부로 배출시키기 위한 배출구(5)를 포함한다. 다만, 본 발명에 따른 해양 구조물은, 흡입구(3)와 배출구(5) 사이의 선체(1)에 설치되고, 해수를 분사시켜 흡입구(3) 주위의 해수와 배출구(5) 주위의 해수를 서로 분리시킬 수 있는 분사장치(7)를 더 포함한다.The marine structure according to the present invention has an inlet 3 for sucking seawater for use as a heat source at the time of regeneration of the LNG into the hull and a hull 3 for discharging the seawater cooled through heat exchange with the LNG to the outside of the hull And an outlet (5). The marine structure according to the present invention is installed in the hull 1 between the inlet 3 and the outlet 5 and seawater is sprayed so that seawater around the inlet 3 and seawater around the outlet 5 And a spraying device 7 capable of being separated.

흡입구(3)는, 예컨대, 선수에 가까운 선체(1) 하부에서 좌현측 및 우현측에 각각 하나씩 형성될 수 있다. 흡입구(3)의 방향은 선체(1)의 폭방향을 따라 각각 좌측 및 우측을 향하도록 형성될 수 있다.The intake port 3 may be formed, for example, one on each of the port side and the starboard side in the lower portion of the hull 1 close to the bow. The direction of the inlet 3 may be formed so as to face the left and right sides along the width direction of the hull 1, respectively.

배출구(5)는, 예컨대, 상기 흡입구(3)로부터 선미쪽의 선체(1) 하부에서 좌현측 및 우현측에 각각 하나씩 형성될 수 있다. 배출구(5)의 방향은 선체(1)의 길이방향을 따라 선미측을 향하도록 형성될 수 있다.The outlet 5 may be formed, for example, one at the bottom of the hull 1 on the stern side from the inlet 3, and one on the port side and one on the starboard side. The direction of the discharge port 5 may be formed so as to be directed to the stern side along the longitudinal direction of the hull 1.

분사장치(7)는 선체(1) 하부에서 흡입구(3)와 배출구(5) 사이에 설치되며, 도 1에 도시된 바와 같이, 분사장치(7)로부터 분사되는 해수가 선체의 바닥으로부터 수직방향 아래를 향하도록 형성되는 것이 바람직하다.The jetting device 7 is installed between the suction port 3 and the discharge port 5 at the lower part of the hull 1 and the seawater jetted from the jetting device 7 is directed vertically As shown in Fig.

도 2에는 4개의 분사장치(7)가 선체(1)의 저면에 설치되는 것으로 도시되어 있지만, 분사장치(7)의 설치개수는 선체(1)의 크기, 흡입구(3)와 배출구(5) 사이의 거리 등을 감안하여 변경될 수 있다.The number of the injectors 7 is determined by the size of the hull 1 and the size of the inlet 3 and the outlet 5 of the hull 1, And the like.

분사장치(7)에 의해 해수가 선체의 수직방향 아래쪽으로 분사됨에 따라, 흡입구(3) 부근의 해수와 배출구(5) 부근의 해수가 서로 섞이는 것을 방지할 수 있다. 배출구(5) 부근의 해수가 해류 등의 외력을 받아 흡입구(3) 쪽으로 유동하더라도, 도중에 분사장치(7)에서 분사되는 해수의 압력에 의해 흡입구(3) 쪽으로 유동하지 못하고 분사장치(7)에서 분사되는 해수와 함께 아래쪽으로 유동하게 되므로, 상대적으로 온도가 낮은 배출구(5) 부근의 해수가 흡입구(3)를 통해 흡입되는 것을 막을 수 있다.The seawater in the vicinity of the suction port 3 and the seawater in the vicinity of the discharge port 5 can be prevented from being mixed with each other as the seawater is injected downward in the vertical direction of the hull by the injector 7. The seawater in the vicinity of the discharge port 5 receives an external force such as a current and flows to the suction port 3 but does not flow toward the suction port 3 due to the pressure of the seawater sprayed by the spray device 7 in the middle, The seawater in the vicinity of the discharge port 5 having a relatively low temperature can be prevented from being sucked through the inlet 3.

이상과 같이 첨부된 도면을 참조하여 본 발명을 설명하였으나, 본 발명은 이상에서 설명된 실시예와 도면에 의해 한정되지 않으며, 특허청구범위 내에서 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자들에 의해 다양한 수정 및 변형이 이루어질 수 있음은 물론이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Various modifications and changes may be made by those skilled in the art.
