摘要:
Disclosed is a pump tower disposed inside a liquefied gas storage tank so as to supply or discharge liquefied gas to/from the inside of the liquefied gas storage tank. The pump tower, according to one embodiment of the present invention, comprises: a discharge pipe used for discharging the liquefied gas in the liquefied gas storage tank; an emergency pipe equipped with an emergency pump at the lower end thereof; a charge pipe for supplying the liquefied gas into the liquefied gas storage tank; and a support, which is provided on the bottom of the liquefied gas storage tank, for enabling the vertical displacement of the pump tower and restricting the horizontal movement and rotation thereof. The support comprises: a lower body fixed to a hull side; an upper body fixed to a pump tower side; and a wedge member interposed between the lower body and the upper body.

Contemplated plant configurations and methods employ a vaporized and supercritical LNG stream at an intermediate temperature that is expanded, wherein refrigeration content of the expanded LNG is used to chill one or more recompressor feed streams and to condense a demethanizer reflux. One portion of the so warmed and expanded LNG is condensed and fed to the demethanizer as reflux, while the other portion is expanded and fed to the demethanizer as feed stream. Most preferably, the demethanizer overhead is combined with a portion of the vaporized and supercritical LNG stream to form a pipeline product.

Disclosed herein is a semi-submersible offshore structure having storage tanks for liquefied gas, which is constructed so as to improve workability in marine offloading of the liquefied gas stored in the storage tanks while reducing an influence of sloshing. The offshore structure is anchored at sea and has liquefied gas. The offshore structure includes a storage tank storing liquefied gas, a plurality of columns partially submerged under the sea level and each having the storage tank therein, and an upper deck located on the plurality of columns to connect the columns to each other.

The present invention comprises a tank for liquefied gases or a so-called cryogenic tank (1) with a tank bottom structure (10) and a tank wall structure (11) arranged around a circumference of the tank bottom structure (10). The tank bottom structure (10) is provided with a tank bottom hub (2) adapted for being held by a bottom hub retainer (20) on a tank support structural floor (23). The tank is simple to install, cheap in production and handles in an improved manner forces acting upon it.

摘要:
A method and apparatus for transporting or storing compressed natural gas in a marine environment includes the providing of a heavy lift vessel that has a weather deck area that is bounded by forward and aft, port and starboard sides or walls that extend above the weather deck. A buoyant module is provided that contains a pipeline, the pipeline including multiple alternating straight sections and bend sections and multiple layers. The pipeline is supported at differing elevations within the module interior so that the various sections of the pipeline are preferably spaced apart to enable visual and/or remote exterior inspection (e.g. video, radar, x-ray, acoustic, or other exterior, non-destructive test) of the outer surface of the pipeline. The pipeline has a continuous bore that is piggable for internal inspections. The module can be transferred to a heavy lift vessel or can be used as flotation. The combination of heavy lift vessel and module can travel to a selected location for loading and unloading compressed natural gas. The module can be placed in a marine environment to serve as a storage facility for compressed natural gas.
