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.

This invention provides a means of loading, processing and conditioning raw production gas, production of CGL, storage, transport, and delivery of pipeline quality natural gas or fractionated products to market. The CGL transport vessel utilizes a pipe based containment system to hold more densely packed constituents of natural gas held within a light hydrocarbon solvent than it is possible to attain for natural gas alone under such conditions. The containment system is supported by process systems for loading and transporting the natural gas as a liquid and unloading the CGL from the containment system and then offloading it in the gaseous state. The system can also be utilized for the selective storage and transport of NGLs to provide a total service package for the movement of natural gas and associated gas production. The mode of storage is suited for both marine and land transportation and configured in modular form to suit a particular application and/or scale of operation.

CO.sub.2 in the liquid or super-critical state is delivered by at least one carrier vessel from at least one CO.sub.2 storage site, which may be an onshore site, to an integrated offshore facility. The integrated offshore facility is provided with at least one on-site storage tank or vessel adapted to store CO.sub.2 in the liquid or super-critical state and with equipment for marine transfer of CO.sub.2 in the liquid or super-critical state. CO.sub.2 is utilised as required from said at least one on-site storage tank or vessel for EOR at said offshore site or for EGR at said offshore site by injection into a sub-sea oil or natural gas bearing reservoir and recovery of oil and/or natural gas from a resulting production stream.

An offshore floating island includes a supporting structure and an island main body. The bottom of the supporting structure is fixed at the seabed, and the island main body includes one or two or more compartment bodies; the upper part of the supporting structure is provided with a carrying part; the bottom of each compartment body is provided with a mounting part; the compartment body is of a cavity structure, and a filler is injected to the compartment body till the compartment body sinks to cause the mounting part to be in lock type clamping with the carrying part. The island main body is of a compartment-sinking type structure; the filler is poured into the compartment bodies to cause the compartment bodies to sink; the mounting parts and the carrying part cooperate to realize detachable connection between the supporting structure and the compartment bodies.

The present invention provides for a method of marine construction. Said marine construction is based on an external perimeter and inner area and comprises seabed lying elements and floating elements. The marine construction of the present invention comprising fixed elements that are placed on the defined perimeter of said marine construction. Said fixed elements are lying on the seabed. And further comprising floating elements that are placed in the inner area the marine construction, defined by said external perimeter. The marine construction is capable of being deployed at a variety of distances from shore, at a differential nature of sea bed, and to be able to carry out different tasks and destinations, such as but not limited to airport, residency, army base, power station, port, marina, other infrastructures, etc. and any combination thereof.

The present disclosure relates to a method for preparing a wind turbine blade for recycling by sectioning the wind turbine into at least a first and a second wind turbine blade part comprising different types of materials or comprising the same type of materials in a different relative content.

Provided is a power generation system including a wave power generator that can be configured in a simple manner.

The power generation system 1 includes: a power generation unit including a wave power generator 11; a power storage unit 40 accumulating electric power obtained by the power generation unit; a production unit 51 producing at least one of hydrogen and an organic hydride based on the electric power obtained by the power storage unit; and a tank 53 located below compared to the wave power generator 11 and storing at least one of the hydrogen and the organic hydride obtained by the production unit 51.

A buoyant structure having a hull, a main deck, an upper cylindrical side section extending downwardly from the main deck, an upper frustoconical side section, a cylindrical neck, a lower ellipsoidal section that extends from the cylindrical neck, an ellipsoidal keel and a fin-shaped appendage secured to a lower and an outer portion of the exterior of the ellipsoid keel. The upper frustoconical side section located below the upper cylindrical side section and maintained to be above a water line for a transport depth and partially below the water line for an operational depth of the buoyant structure.
