Embodiment Construction

[0048] figure 1 A side view of an LNG carrier 10 according to an embodiment of the present invention is shown.

[0049] LNG carrier 10 includes a hull 14 and a main deck 16 .

[0050] The LNG carrier 10 is also provided with storage capacity for LNG through a plurality of LNG tanks 20 , 22 . LNG tanks 20, 22 are installed in the cargo hold of each of the carriers.

[0051] The plurality of LNG tanks includes one or more LNG tanks 20 of a first spherical type arranged in a cargo hold C1 (indicated as main cargo hold) within the hull 14 of the LNG carrier 10 . The size of the spherical LNG tank 20 is determined such that a part of the ball protrudes above the main deck 16 .

[0052] According to the prior art, spherical LNG tanks are called Moss-type LNG tanks.

[0053] According to the present invention, the LNG carrier 10 also includes one or more second non-spherical LNG tanks 22 in one or more of the remaining cargo tanks C2 (denoted as secondary cargo tanks) of the LNG ...

Abstract

A LNG carrier vessel is provided with a hull, a main deck, a plurality of cargo holds below the main deck, and LNG storage tanks. A first number of the cargo holds is configured as primary cargo holds that each include e a first type LNG storage tank arranged as a spherical type LNG tank inside the hull with a portion of the spherical tank protruding above the main deck. A second number of the cargo holds is configured as secondary cargo holds that each either are void of an LNG storage tank or comprise a second type LNG storage tank that is not a spherical-type LNG tank and fits into the respective cargo hold. A first portion of an area of the main deck above the secondary cargo holds is provided with process equipment for LNG processing. If the respective second cargo hold is equipped with a second type LNG storage tank, a second portion of the area of the main deck above the secondary cargo holds is free from processing equipment and includes an open space with an opening for access to the second type LNG storage tank in the respective secondary cargo hold.

Description

technical field [0001] The present invention relates to an LNG carrier. The invention also relates to a method of manufacturing such an LNG carrier. Furthermore, the present invention relates to floating LNG platforms. Background technique [0002] Floating LNG plants, essentially floating production, storage and offloading (FPSO) vessels for LNG, are commonly used by the offshore oil and gas industry to handle natural gas feeds and store liquefied natural gas (LNG). FPSO vessels are designed to receive feed gas, including natural gas and other components, from nearby platforms or from subsea wells. The received feed gas is processed through on-board processing equipment to separate the natural gas from its other components, then liquefied by cooling to cryogenic temperatures and stored as LNG in tanks onboard the FPSO until the liquid is transferred to transport it To the LNG carrier at the land terminal. [0003] Typically, spherical storage tanks are used to store LNG...
