Embodiment Construction

[0034] FIG. 1 illustrates the general arrangement of a typical Moss-type LNG carrier 1 . The LNG carrier 1 is used to store LNG. The LNG carrier 1 basically includes a hull 2 ​​in which a spherical LNG storage tank 3 is arranged. The LNG carrier 1 is well known to those skilled in the art and will not be described in detail here. In the specific embodiment shown in FIG. 1 , the LNG carrier 1 includes four spherical LNG storage tanks 3 .

[0035] reference now figure 2 , figure 2 The present invention is illustrated as an apparatus 11 for suspension production of LNG (ie FLNG). As shown in FIG. 1 , the apparatus includes an LNG carrier 1 including a hull 12 and at least one spherical LNG storage tank 13 for storing LNG.

[0036] The device 11 can be utilized as a substantially stationary suspension unit anchored to the seabed or secured by the DP; natural gas is converted to LNG on the device 11 and the tank 13 is used for interim storage. In this way, LNG is delivered to...

Abstract

The invention relates to a device for floating production of LNG. The device comprises a LNG carrier comprising a ship hull (12) and at least one spherical LNG storage tank (13) for storing LNG, a projecting hull structure (16) fixed to the ship hull (12), a LNG production system (17) for converting natural gas to LNG, where the LNG production system is arranged in the projecting hull structure (16) and means for transferring LNG from the LNG production system (17) to the at lest one spherical LNG storage tank (13). The invention also relates to a method for converting an LNG-carrier to a device for floating production of LNG.

Description

technical field [0001] The present invention relates to a device for floating production of LNG and a method for transforming an LNG carrier into a device for floating production of LNG. Background technique [0002] In order to deliver natural gas to distant markets, the gas can be converted into LNG (liquefied natural gas) and transported at sea using LNG carriers. So far, more than 280 transport ships have been built around the world. Due to the low temperature of the cargo (-163°), the cargo accommodating system on the LNG carrier is a complex and costly device. Over the years, designers and shipbuilders have made considerable efforts to optimize technology and reduce the cost of LNG carrier containment systems. [0003] The LNG carrier market has been and will continue to be completely dominated by two containment system designs, the Moss spherical tank and the membrane design. [0004] In recent years, the concept of creating floating LNG production units, commonly ...
