Two adjacent pipe flanges are secured by a plurality of clamp units, where each clamp unit, in order to receive the adjacent flanges in its receptacle, is thermally expanded.

Method of connecting tubular members in offshore structures

A first and a second tubular member are welded to opposite sides of a stiffening ring in order to obtain a double-segment. Further segments can be added to form a tubular multi-segment with stiffening rings in between adjacent tubular members. The resulting multi-segment is used as a tubular buoyancy module in a floating offshore structure.

An electrolysis system with a buffer tank An electrolysis system for production of hydrogen and/or oxygen comprising a stack of electrolysis cells inside a pressure vessel (). Each electrolysis cell in the stack comprises a membrane (A,B) and a cassette () made of a bipolar plate () sand-wiched by a cathode (B) and an anode () forming a cathode compartment and an anode compartment on each side of the bipolar plate (). The stack is enclosed in a container constituting a buffer container for storing hydrogen released in the stack. The stack has an outlet constituting a hydrogen outlet for flow of hydrogen gas into said buffer container for filling the buffer container with hydrogen gas.

Various embodiments of the present disclosure are directed to offshore frame construction. In one example embodiment, an offshore frame construction is disclosed including structural members and a structural joint connecting the structural members. The structural joint includes a fork part, an ear part, and a pin, where the fork part and the ear part includes a bore, and the pin is inserted into the bore. The pin has a non-corroding surface that is a cladding or bushing welded or shrunk or glued or otherwise affixed to the pin which consists of a different material, or the non-corroding surface is continuous with the pin and the pin consists of the non-corroding material. In some specific embodiments, the bore includes a sliding surface, which is fitted with a liner acting as a bearing, and the bearing is an elastomeric bearing.

An offshore floating structure is provided including a floater with positive buoyancy and a keel with negative buoyancy, as well as active and passive suspenders connecting nodes of the keel and the floater with each other. When the keel at the offshore site is lowered by making the active suspenders longer, the passive suspenders, which have a fixed length and are held taut, causes the keel to rotate about the vertical during lowering.

An energy storage system comprises a hot thermal energy storage medium and a cold thermal energy storage medium, which are interconnected in a thermodynamic gas flow circuit with gas as a working fluid. An energy converter with a motor/generator system is functionally connected to a compressor/expander system for converting between electrical energy and thermal energy of the gaseous working fluid in the thermodynamic fluid circuit. A latent TES medium is thermally connected to the thermodynamic circuit for providing a lower limit for the temperature in the cold TES medium. Specifically, the latent TES medium is liquid, typically water, which is sprayed as droplets into a tank through which the gaseous working fluid flows at subzero temperatures to produce snow in order to efficiently heat the gas to the freezing point or above.

Operation of an energy storage system comprising a thermodynamic cycle including first and second thermal reservoirs and a turbomachinery as energy converter for two-way conversion between electrical energy and thermal energy. For controlling the temperature in the system, the compression ratio of the turbomachinery is adjusted in real-time during charging on the basis of temperature measurements downstream of the compression and/or during discharging on the basis of temperature measurements downstream of the expansion.

The application relates to a floatable foundation structure for an offshore structure including at least one floating body arrangement and at least one mass arrangement. The mass arrangement is connected to the floating body arrangement by at least one holding rope in a coupling state. Further, in the coupling state for coupling the floating body arrangement to the mass arrangement, a coupling section of the holding rope is arcuately guided around a contact section of the mass arrangement.

A protection system for a threaded fastener is provided. The system includes a threaded fastener, a sleeve and either two end caps, or one end cap and one threaded hole in a component. To avoid exposure to severely corrosive environments the sleeve and either the two end caps, or the one end cap and the one threaded hole, together form an enclosure around the threaded fastener. The enclosure forms a cavity which is completely sealed from the environment. Furthermore, methods are described for mounting, inspection and maintenance of such protection system.

Provided is a floating wind turbine including a hull, a wind turbine mounted on top of the hull and a counterweight suspended below the hull by a counterweight suspension is described. Also, a method for the installation is described. The counterweight includes one or more counterweight buoyancy tanks. When the internal volume of the buoyancy tanks is filled with air, the total buoyancy of the counterweight is close to or greater than its weight. Hereby it is capable of floating in a towing/maintenance position with moderate or no support in the vertical direction from the hull or other vessels. During towing, the hull substantially has the character of a barge, substantially relying on a large waterplane area and shallow draft to maintain stability.

A method for manufacturing a component for a wind turbine is provided. In a first step, a fiber material is laid onto a mold surface. In a further step, an uncured foam material is provided on top of the fiber material. Thereafter, the uncured foam material is cured to form a core member. Then, a resin impregnating the fiber material is cured to form the component. Thus, a core member for a component of a wind turbine can be provided easily.
