The present invention utilize a combination of wooden elements (20, 21), stainless steel membranes (22) and insulating materials in embodiments of the present invention. An object of the present invention is to be able to build the LNG tank separately from the building of the ship, and fit a complete or nearly complete LNG tank into the space of the ship hull when appropriate during the process of building the ship. Therefore, the building of the tank and the ship can be done in parallel, which by experience reduces the total time of building the ship considerably, and hence provide substantial cost savings.

An LNG production plant positioned at a production location adjacent to a body of water is described. The LNG production plant includes a plurality of spaced-apart facilities including a first facility and a second facility, each facility provided with plant equipment related to a pre-determined function associated with the production of LNG, where the first facility is an onshore facility and the second facility is an integrated storage/offloading facility arranged on a gravity-based structure having a base that rests on the seabed at a selected location within the body of water.

A method, including: obtaining a stand-alone liquefied gas storage tank, wherein the liquefied gas storage tank includes a membrane insulation system; and disposing the liquefied gas storage tank onto a storage tank pre-installed foundation.

The present invention relates to a natural gas hydrate tank container loading system for transporting natural gas hydrate, and the present invention provides a natural gas hydrate tank container loading system which enables automated connection of an electric power line and a boil-off pipe, and may automatically connect an electric power line and automatically connect the pipe by simultaneously stacking respective natural gas hydrate tank containers, in order to solve problems of a transportation method using the existing natural gas hydrate tank containers in the related art in that an operation of connecting an electric power line to a refrigerator for minimizing the occurrence of boil-off gas and maintaining a phase equilibrium condition in the tank containers and an operation of connecting the pipe for discharging the boil-off gas need to be manually and individually performed for long-distance transportation of a large amount of natural gas hydrate by using a ship, which causes an inconvenience.

The invention relates to an arrangement of one or more cryogenic tank containers for storing liquefied natural gas (LNG) or compressed natural gas (CNG) on an open deck of a tugboat. The one or more cryogenic tank containers are removably mounted on and at an aft deck area of the tugboat and are provided with means for supplying LNG or CNG to the engine of the tugboat.

Herein a floating vessel is disclosed. The floating vessel comprises a deck member and a tank for liquefied hydrocarbon gas such as LNG. The tank extends through the deck member, and the tank is supported by the deck member, suspended at less than of a total height of the tank, seen from the top of the tank.

The present invention relates to a fuel tank arrangement of a marine vessel including a fuel tank for Liquefied Natural Gas, the fuel tank having a shell, a heat insulation in connection therewith, connections for a pipeline for bunkering LNG to the fuel tank, a pipeline for taking boil-off gas from the fuel tank and a pipeline for taking LNG from the fuel tank, and a deep well pump for pumping LNG from the tank to the pipeline, wherein at least one recess is extending inwardly from the shell and being arranged on top of the fuel tank, the deep well pump being installed in the at least one recess.

This invention relates to methods of fabricating components of a pressure vessel using a dicyclopentadiene prepolymer formulation in which the purity of the dicyclopentadiene is at least 92% wherein the formulation further comprises a reactive ethylene monomer that renders the prepolymer formulation flowable at ambient temperatures and to pressure vessels that are fabricated by said methods.

Method for the production of a high-resistance tank has an initial stage in which a closed metal vessel is formed, followed by a second stage in which the walls of the vessel are subjected to a mechanical pre-tensioning treatment in both the axial and radial directions, up to a predetermined value. This mechanical treatment has a stage in which the tank is enclosed inside a mould of suitably larger dimensions. A liquid is then introduced in the tank and pressurized until the tank walls are dilated and stretched to a point where they encounter the mould inner surface. Subsequently, the outside of the tank is coated with one or more layers of composite material, so as to complete the construction of the tank, upon which a final auto-frettage treatment is carried out. The type of steel to be used is AISI 304, preferably in its more weldable AISI 304L version.

A ship for transporting cargo gas, such as natural gas, includes a ship structure and a middle transverse bulkhead constructed by gas storage containers. Each gas storage container includes an enclosure and a pipe coil within the enclosure that contains the cargo gas and it is the enclosures of the gas storage containers that are integrated into the ship structure to form the middle transverse bulk head.
