Abstract

?embarcação de liquefação de gás natural? a presente invenção refere-se a uma embarcação de liquefação de gás natural incluindo uma maior tonelagem de peso morto, em comparação com um transportador de gás natural liquefeito (gnlc) de um navio de tamanho comparável, que é alcançada pela redução da capacidade de carga do gnlc. essa diferença cria espaço nos lados de bombordo e estibordo dos tanques de carga para aumentar o tamanho dos tanques adjacentes. o aumento do tamanho dos tanques ocupa o espaço criado pelo tamanho reduzido do tanque de carga da embarcação e pode suportar um maior convés de tronco superior. os tanques de lastro e tanques de carga menores aumentam o peso morto disponível. com esta abordagem, o maior convés de tronco superior é capaz de suportar uma planta de liquefação flutuante eficiente que melhora a cadeia de valor de gnl porque é capaz de produzir 2.0 - 3.0 mtpa na área útil de um casco de embarcação padrão, tal como, por exemplo um casco q-max.? natural gas liquefaction vessel? The present invention relates to a natural gas liquefaction vessel including a larger deadweight tonnage compared to a liquefied natural gas (gnlc) carrier of a comparable size vessel which is achieved by reducing the carrying capacity. from gnlc. This difference creates space on the port and starboard sides of the cargo tanks to increase the size of the adjacent tanks. Increasing tank size takes up space created by the vessel's reduced cargo tank size and can support a larger upper trunk deck. smaller ballast tanks and cargo tanks increase available deadweight. With this approach, the larger upper trunk deck is capable of supporting an efficient floating liquefaction plant that improves the LNG value chain because it is capable of producing 2.0 - 3.0 mtpa in the usable area of a standard vessel hull such as, for example a q-max hull.
