  • Patent number: 12640543
    Abstract: An offshore system including: a dynamic submarine power cable, a bend stiffener having a lower end and a top end, the bend stiffener having a central channel extending from the lower end to the top end, the central channel receiving the dynamic submarine power cable with a radial spacing between an inner surface of the central channel and an outer surface of the dynamic submarine power cable along the length of the dynamic submarine power cable arranged in the bend stiffener, the radial spacing forming a longitudinal water channel between the bend stiffener and the dynamic submarine power cable, and an offshore structure tube connected to the bend stiffener, wherein the offshore structure tube has an inner tube channel in fluid communication with the longitudinal water channel, and wherein A) the offshore structure tube has a through-opening extending from the inner tube channel through a wall of the offshore structure tube to enable water flowing from the lower end through the bend stiffener to exit the offs

  • Publication number: 20250336565
    Abstract: Method of manufacturing a power cable including three cores and three filler profiles arranged in a stranded configuration, the method including: A) in a design stage of the power cable: A0) defining a nominal outer diameter of the cores, and defining a stranding pitch P of the cores, A1) determining, in a transverse plane of the power cable, a shape of at least one of the cores, A2) determining a cross-sectional shape of the filler profiles in a transverse section of a filler profile based on the shape determined in step A1), B) in the production stage of the power cable: B1) manufacturing each of the cores with the nominal outer diameter, B2) obtaining the filler profiles with the cross-sectional shape obtained in step A2), and B3) stranding the cores and the filler profiles with the stranding pitch P in an assembly machine.
