  • Power umbilical and method
    Patent number: 11978575
    Abstract: Power umbilical (1) comprising a plurality of power cables (7) for electric power transmission, elongated filler elements (5), and an outer sheath (3). The elongated filler elements (5) abut against each other at abutment faces (5a), thereby forming a complete ring enclosing the power cables (7). The elongated filler elements (5) comprise cable recesses (5b) within which the power cables (7) are embedded. The power umbilical (1) further comprises one or more friction control profiles (13, 15, 116), wherein the material of the friction control profile (13, 15, 116) is softer than the material of the elongated filler elements (5). The one or more friction control profiles (13, 15) are arranged in a deformed state.

  • Power umbilical with impact protection
    Patent number: 11270812
    Abstract: The invention concerns a subsea umbilical comprising an electrical conductor (2) and/or a fluid pipe, and an outer sheath (7) surrounding the electrical conductor (2) and/or the fluid pipe. The umbilical (1, 20, 21, 25, 30, 40, 51, 60) further comprising a plurality of deformable rods (3a, 3b, 15, 23a, 23b, 26a, 27a, 26b) evenly distributed between the electrical conductor (2) and/or the fluid pipe, and the outer sheath (7) for radial load protection of said electrical conductor (2) or fluid pipe.
