An offshore LNG processing plant includes a first module including a personnel accommodation facility on a first vessel, a second module including a gas treatment facility on a second vessel, and a third module including a gas liquefaction facility on a third vessel. Each of the first, second, and third modules are assembled on the corresponding vessels, and then transported to an offshore location in a body of water, such as a river, a lake, or a sea. At the offshore location, each vessel deploys legs to the bed of the body of water to raise a hull of each vessel out of the water. The first module is then coupled to the second module, and the second module is coupled to the third module. A fourth module on a fourth vessel is coupled to the third module to provide LNG storage.

The invention discloses a paired air pressure energy storage device, an inspection method and a balance detection mechanism thereof. The paired air pressure energy storage device includes an inner body and an outer body sleeved outside the inner body. The inner body is filled with a first gas. A cavity formed between the outer body and the inner body is filled with a second gas. There is a gas energy pressure difference between the first gas and the second gas. The gas energy pressure difference is relative pressure gas energy. The invention can store two gases with different pressure intensities, has a simple structure, is convenient for transportation, and is favorable for effective energy storage and long-term storage of gases.

This publication relates to a shallow water terminal, preferably for storing and loading or unloading hydrocarbons, such as LNG, oil or gas. The base structure comprises a floatable, and removable seabed substructure (10) intended to be supported by a seabed (30), the seabed substructure (10) comprising a base structure (11) provided preferably with an upwards extending wall structure (22), arranged along at least a part of the periphery of the base structure (11), the base structure (10) preferably also being provided with an opening (23) in the wall structure (22) for allowing the floatable module to be berthed in and supported by the seabed substructure (10). The base structure (10) is provided with strong points (24) configured to receive the ends of preinstalled vertical piles (14) for at least temporary support of the base structure (11) during a piling operation for permanent piling of the base structure (10) to the sea bed (30). The publication also relates to a method for piling a base structure on or above a seabed (30).

A storage system for temporary storage of a gas comprising a storage vessel configured to store a pressurized gas or liquid; at least one of a compressor configured to pressurize the gas and provide the pressurized fluid or a liquefaction apparatus operable to liquefy the gas to provide the liquid; and piping associated with one or more valves, wherein the piping and the associated one or more valves are configured to provide: (a) in a first configuration, inflow of the gas into the compressor or the liquefaction apparatus, wherein the compressor is configured to pressurize the inflowing gas to provide the pressurized fluid or wherein the liquefaction apparatus is configured to liquefy the inflowing gas to provide the liquid, and introduce the pressurized gas or the liquid into the temporary storage vessel; and (b) in a second configuration, outflow of the pressurized gas or liquid from the temporary storage vessel.

Various embodiments relate to a method and a harbour plant for mooring a floating body. The harbour plant includes a piled base structure provided with two upwards through sea level projecting sidewalls terminated above sea level and a laterally arranged bottom structure interconnecting the sidewalls, where a top surface of the bottom structure is arranged at a depth allowing the floating body to be floated in between the sidewalls, and where the floating body is arranged to be rigidly, but releasably supported by at least parts of the sidewalls. The method includes bringing the floating body into a position between the sidewalls and fixing rigidly the floating body to the vertical sidewalls of the base structure and still exposing the floating body more or less fully to buoyancy by allowing a water-filled gap at least between bottom of the floating body and a corresponding upper surface of the base structure.
