  • Publication number: 20240262471
    Abstract: A floating fabrication arrangement for building of floating structures (15). It comprises floating unit (1-4) having a continuous deck, at least one crane (5, 6) attached to said floating unit (1-4) and a mooring arrangement capable of mooring the floating unit (1-4) in a floating state on a body of water. The floating unit (1-4) having ballast chambers capable of ballasting and de-ballasting the floating unit (1-4) between a first building position where the floating unit (1-4) floats with the deck above water in a substantially horizontal position and a second inclined launch position, in which a first part of the deck is submerged and a second part of the deck is above water. A method of building floating structures is also described.

  • Publication number: 20240011467
    Abstract: A wind turbine, having a floating foundation (1), a support structure (2) and a generator (3). The generator (3) is an up-wind generator. The floating foundation (1) is assembled from tubular steel sections (5, 6, 7, 8) of uniform diameter, forming a frame with a mooring turret (4) at one corner. The support structure (2) hays at least two beams (11, 12) extending substantially transverse to the floating foundation (1). The beams are connected at a first end to a respective opposite side of said foundation frame and at a second end to said nacelle (17). The support structure (2) and the floating foundation (1) form a triangle with the nacelle (17) fixedly mounted at the apex. The support structure (2) comprises tensioned backstays (13, 14, 15, 16) supporting the beams (11, 12) and ensuring that they are substantially subjected to compression forces only.

  • Publication number: 20230332576
    Abstract: A method and an installation facility for assembling a plurality of floating wind turbines (12). The method comprising establishing an installation facility by arranging an installation vessel (1), having a crane (4), at a sheltered place, mooring a barge (2) next to said vessel (1). Further transporting a plurality of turbine blades (6), a plurality of tower sections (8) and a plurality of nacelles (10) to said installation facility, lifting of these parts onto said installation facility. Further towing a first floating wind turbine foundation (11 a) to said installation facility, erecting a tower (8a) on said first foundation (11 a) by assembling a set of said tower sections (8), installing a nacelle (10) on top of said tower (8a), installing a set of turbine blades (6) onto said nacelle (10) to make a completed wind turbine (12a), and finally towing said first wind turbine (12a) away.
