Natural gas liquefaction vessel

A natural gas liquefaction vessel including an increased deadweight tonnage, as compared to a liquefied natural gas carrier (LNGC) of a comparably-sized ship, is achieved by reducing the LNGC's cargo capacity. This difference creates room on the port and starboard sides of cargo tanks to increase the size of the adjacent wing tanks. The increased size of the wing tanks occupy the space created by the reduced cargo tank size of the vessel and may- support a larger upper trunk deck. The ballast wing tanks and smaller cargo tanks increase the deadweight available. With this approach, the larger upper trunk deck of the vessel is able to support an efficient floating liquefaction plant that improves the LNG value chain because it is capable of producing 2.0 - 3.0 MTPA in the footprint of a standard vessel hull, such as for example a Q-Max hull ...

Bending Stiffness Reducer for Brace to Hull Connection

Semi-submersibles are subjected to loading from waves, causing racking, longitudinal shear and parallelogramming, or differential movement of the pontoons. The cyclic wave loading makes the various connections, where stress concentrations occur, susceptible to fatigue damage throughout the hull structure. This is most evident at the connections between the braces and the main hull structure. A revised brace to main hull connection with reduced bending stiffness is employed to reduce the moment being transferred from the brace to the hull, thereby reducing the bending stress and susceptibility to fatigue damage. This improved connection employs an internal member to transfer the loads between the brace and hull structure mainly as tension and compression. As a consequence of the improved fatigue performance, the structural weight of the connection can be greatly reduced, thus increasing the capacity with which the semi-submersible hull can operate. 1.

본 발명은 중심축(111)에 대하여 실질적으로 대칭이고, 복수개의 제1 구획공간들(21; 31, 21'; 21")이 중심 구조물(11; 11'; 11")과 2개 이상의 제2 구획공간들(22a; 22a'; 22a") 사이에 배열되고, 2개의 인접한 제1 구획공간들이 상기 중심 구조물로부터 실질적으로 반지름 방향으로 바깥쪽으로 선체 측부(hull side)(13)를 향해 연장되는 제1 벌크헤드(bulkhead)(211; 211'; 211")에 의해 서로 분리되는 선체(hull)(1; 1'; 1")의 탱크 시스템(2)에서 있어서, 제3 구획공간(22b; 22b'; 22b")이 2개의 인접한 제1 구획공간들(21)에 대향하여 그리고 인접한 제2 구획공간들(22a; 22a'; 22a")에 대향하여 구획되고, 상기 제3 구획공간이 선체(1)의 치수화된 최대 손상 깊이 연장(dimensioning, maximum damage depth extension)보다 더 큰 반지름 방향의 연장(radial extension)을 나타내는 것을 특징으로 하는 탱크 시스템을 개시한다. The present invention is substantially symmetrical with respect to the central axis 111, the plurality of first partition spaces (21; 31, 21'; 21") and the central structure (11; 11'; 11") and two or more agents It is arranged between the two compartments 22a; 22a'; 22a", and two adjacent first compartments extend outward from the center structure in a substantially radial direction toward the hull side 13 In the tank system 2 of a hull 1; 1'; 1" separated from each other by a first bulkhead 211; 211'; 211", the third compartment 22b; 22b'; 22b") is divided into two adjacent first compartments 21 and opposite second compartments 22a; 22a'; 22a", the third compartment being the hull Disclosed is a tank system characterized by exhibiting a radial extension greater than the dimensioned maximum damage depth extension of (1).

반잠수식 해양구조물이 개시된다. 본 발명의 실시예에 따른 반잠수식 해양구조물은 반잠수식 본체; 및 상기 본체를 해저에 대해 지지하는 텐던을 포함하고, 상기 본체에는 유체가 통과하는 유체통과부가 해수면에 걸쳐 형성된다.

A Gas Treatment System Of Boil-off Gas And Flash Gas Of LNG For LNG FPSO

본 발명의 일 실시예에 따른 LNG FPSO용 기화가스 처리 시스템은, 액화공정 플래쉬탱크로부터 유입처까지 연결되는 가스공급라인; 상기 가스공급라인 상에 마련되어 상기 액화공정 플래쉬탱크로부터 배출되는 액상의 가스가 축적되거나, 가스를 기체와 액체로 분리하는 상류 스크러버; 상기 가스공급라인 상에서 상기 상류 스크러버의 하류에 마련되며, 상기 스크러버로부터 배출되는 기화가스를 가압하는 컴프레서; 및 상기 가스공급라인 상에서 상기 컴프레서의 하류에 마련되며, 상기 컴프레서에서 가압된 가스를 기체와 액체로 분리하는 하류 스크러버를 포함하되, 상기 유입처는, 상기 하류 스크러버의 상류 및 상기 하류 스크러버의 하류 각각에 복수로 마련되어, 상기 컴프레서로부터 배출되는 기화가스가 저장되거나, 상기 하류 스크러버로부터 배출되는 기화가스를 공급받는 것을 특징으로 한다. 본 발명에 따른 LNG FPSO용 기화가스 처리 시스템은, LNG FPSO공정에서 발생한 저온 저압의 플래쉬 가스 및 BOG 가스를 처리하기 위한 플레어 시스템의 과도한 운전을 줄일 수 있다. A gasification processing system for LNG FPSO according to an embodiment of the present invention includes: a gas supply line connected from a liquefaction process flash tank to an inlet; An upstream scrubber provided on the gas supply line for accumulating liquid gas discharged from the liquefaction process flash tank or separating the gas into a gas and a liquid; A compressor provided on the gas supply line downstream of the upstream scrubber to pressurize the vaporized gas discharged from the scrubber; And a downstream scrubber provided downstream of the compressor on the gas supply line, the downstream scrubber separating the gas pressurized by the compressor into a gas and a liquid, the inlet being located upstream of the downstream scrubber and downstream of the downstream scrubber And a plurality of vaporized gases discharged from the compressor may be stored or may be supplied with vaporized gas discharged from the downstream scrubber. The vaporized gas processing system for LNG FPSO according to the present invention can reduce the excessive operation of the flare system for treating low temperature low pressure flash gas and BOG gas generated in the LNG FPSO process.
