  • Publication number: 20230264784
    Abstract: A floating support structure for supporting a windmill system includes a windmill tower, a windmill nacelle, and windmill blades. The support structure includes an aft main section, a transverse main section, and a connecting flange. The aft main section includes a horizontal aft part with a first horizontal aft end and a second horizontal aft end, a vertical aft part with a first vertical aft end at least indirectly connected perpendicular to the first horizontal aft end and a second vertical aft end, and an aft damping structure connected to the second vertical aft end. The vertical and the horizontal aft parts are oriented in a common vertical aft plane. A horizontal cross sectional area of the aft damping structure is larger than a horizontal cross-sectional area of the second vertical aft end.

  • Patent number: 10953963
    Abstract: The present invention relates to a spread moored vessel for production and/or storing of hydrocarbons. The vessel comprises a laterally extending main deck, a symmetrical mooring arrangement for mooring the vessel to a seabed when the vessel is floating in a body of water and a longitudinal hull. The longitudinal hull further comprises a bow, a midbody, a stern, and a motion suppressing element protruding out from the longitudinal hull, below the vessel's maximum draught. The ratio between a maximum length (Lwl) and a maximum breadth (Bwl) of the longitudinal hull, at the vessel's maximum draught, is between 1.1 and 1.5. The specific hull shape with the particular length/breadth ratio and the motion suppressing element allows for favorable and uniform motions regarding of wave direction in relation to vessel heading.

The longitudinal hull further comprises a bow, a midbody, a stern, and a motion suppressing element protruding out from the longitudinal hull, below the vessel's maximum draught. The ratio between a maximum length (Lw1) and a maximum breadth (Bw1) of the longitudinal hull, at the vessel's maximum draught, is between 1.1 and 1.5. The specific hull shape with the particular length/breadth ratio and the motion suppressing element allows for favorable and uniform motions regarding of wave direction in relation to vessel heading.

  • Publication number: 20190144083
    Abstract: The present invention relates to a longitudinal vessel for production and/or storage of hydrocarbons. The vessel comprises a hull which extends along a longitudinal axis between a bow and a stern of the vessel. The hull is provided with a longitudinal well for a multiple riser arrangement. The longitudinal well is located on or adjacent to a centerline along the longitudinal axis of the hull and extends vertically through the hull.
