터릿을 가지는 부유식 해양 구조물{FLOATING MARINE STRUCTURE HAVING TURRET}FLOATING MARINE STRUCTURE HAVING TURRET}

본 고안은 터릿을 가지는 부유식 해양 구조물에 관한 것으로서, 터릿의 해수 흡입라인을 통해 흡입되는 해수가 해수펌프에 도달하도록 하는 배관 구조를 단순화할 수 있고, 터릿의 설치 공간 하부가 해수로 인해 부식되거나 접근성이 저하되는 것을 방지하도록 구성된 터릿을 가지는 부유식 해양 구조물에 관한 것이다.The present invention relates to a floating offshore structure having a turret, which can simplify the piping structure for the seawater drawn through the seawater suction line of the turret to reach the seawater pump, and the lower portion of the turret's installation space is corroded by seawater or A floating offshore structure with a turret configured to prevent degradation of accessibility.

일반적으로, 선박을 비롯한 부유식 해상 구조물은 온도가 낮은 해수(Seawater)를 내부로 끌어올려서 청수나 냉매 등과의 열교환을 통해서 엔진이나 발전기 등의 발열 장치를 냉각시키는데 사용하거나, 액화천연가스(이하, 'LNG'라 함)를 저장하는 경우 냉매와의 열교환을 통해서 천연가스를 액화시키는데 사용되고 있으며, 그 외에도 다양한 용도로 사용되고 있다.In general, a floating offshore structure including a vessel is used to cool a heat generating device such as an engine or a generator through heat exchange with fresh water or a coolant by raising seawater having a low temperature to the inside, or liquefied natural gas (hereinafter, 'LNG') is used to liquefy natural gas through heat exchange with the refrigerant, and is used for various purposes.

한편, 부유식 해상 구조물로는 해저 유전에서 채굴한 원유를 저장함과 아울러 저장된 원유를 셔틀 탱커(shuttle tanker)로 이송하는 설비를 갖춘 FPSO(Floating Production, Storage, and Offloading Unit), LNG를 싣고 바다를 운항하여 육상 소요처에 도착한 후 저장된 LNG를 재기화하여 천연가스 상태로 하역하는 LNG RV(Regasification Vessel), 생산된 천연가스를 해상에서 직접 액화시켜서 저장탱크 내에 저장하고 저장탱크 내에 저장된 LNG를 LNG 수송선으로 옮겨싣기 위해 사용되는 FLNG(LNG FPSO)와, 육상으로부터 멀리 떨어진 해상에서 LNG 수송선으로부터 하역되는 LNG를 저장탱크에 저장한 후 필요에 따라 LNG를 기화시켜 육상 수요처에 공급하는 LNG FSRU(Floating Storage and Regasification Unit) 등이 있으며, 이러한 부유식 해상 구조물에 대한 수요가 점차 증가하고 있다.Floating offshore structures, on the other hand, contain FPSOs (Floating Production, Storage, and Offloading Units), LNG, which are equipped with the facilities for storing crude oil mined from subsea oil fields and transferring the stored crude oil to shuttle tankers. LNG RV (Regasification Vessel) which re-gass the stored LNG after it arrives at the land requirements and unloads it to natural gas state, and liquefies the produced natural gas directly at sea to store it in the storage tank and LNG stored in the storage tank. FLNG (LNG FPSO), which is used for transporting to the sea, and LNG FSRU (Floating Storage and Regasification Units), and the demand for these floating offshore structures is increasing.

이와 같은 원유나 LNG 등과 같은 액체 화물을 해상에서 수송하거나 보관하는 부유식 해상 구조물은 터릿(Turret)과 같은 일점 계류계에 의해 계류된 채 사용되는데, 이러한 일점 계류 방식은 바람, 조류 및 파랑과 같은 환경에 의해 가해지는 외력의 방향이 자주 변하는 해역에서 터릿을 중심으로 자유롭게 회전할 수 있도록 하여 부유식 해상 구조물에 작용하는 외력이 최소가 되도록 한다. 터릿은 상기된 바와 같은 계류기능 이외에도 부이 및 라이저를 통한 원유나 LNG 등의 이송기능을 수행할 수 있는 구성을 가질 수도 있다.Floating offshore structures that transport or store liquid cargo such as crude oil or LNG are used by mooring by a one-point mooring system, such as Turret. The minimum external force acting on the floating offshore structure is to be freely rotated around the turret in the sea where the direction of external force applied by the environment changes frequently. In addition to the mooring function as described above, the turret may have a configuration capable of performing a transfer function of crude oil or LNG through buoys and risers.

In particular, in order to fill the lower portion of the turret installation space with seawater in order to pump the seawater sucked through the seawater suction line by the seawater pump, the installation space of the turret is corroded by the seawater, or difficult to access Had problems.

본 고안은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로서, 터릿의 해수 흡입라인을 통해 흡입되는 해수가 해수펌프에 도달하도록 하는 배관 구조를 단순화하도록 하고, 터릿의 설치 공간 하부가 해수로 인해 부식되거나 접근성이 저하되는 것을 방지하고자 한다.The present invention is to solve the conventional problems as described above, to simplify the pipe structure to allow the seawater sucked through the seawater suction line of the turret to reach the seawater pump, the lower portion of the turret installation space corrosion due to seawater To prevent or reduce accessibility.

상기 목적을 달성하기 위한 본 고안의 일 측면에 따르면, 터릿을 가지는 부유식 해상 구조물에 있어서,상기 터릿에 장착된 해수 흡입라인으로부터 해수가 공급되도록 상기 터릿의 턴테이블에 설치되는 해수용 스위블; 및 상기 해수용 스위블에 연결되어 상기 해수를 해수펌프 측으로 공급하는 해수 공급관을 포함하는 것을 특징으로 하는 터릿을 가지는 부유식 해양 구조물이 제공된다.According to an aspect of the present invention for achieving the above object, In the floating offshore structure having a turret, Seawater swivel installed on the turntable of the turret so that seawater is supplied from the seawater suction line mounted to the turret; And a seawater supply pipe connected to the seawater swivel and supplying the seawater to the seawater pump side.
