  • Publication number: 20140138115
    Abstract: The present arrangement provides an umbilical 1 for subsea application having at least one power phase 9, each power phase comprises at least one conductor 2. The at least one conductor is a massive conductor made in aluminium, or any suitable alloy thereof, and has sufficient tensile strength to ensure that the umbilical supports operating loads without requiring any additional load bearing elements.

  • Publication number: 20060016502
    Abstract: The invention relates to an umbilical comprising at least two elongated elements chosen from a group consisting of steel tubes (1,2), electrical cables (4), optical fiber cables (3), and combinations thereof arranged side by side within a common outer sheath (5) along the length of the umbilical, where the interstices between the elongated elements (2,3,4) and the elongated elements (2,3,4) and the common sheath (5) are filled with a fluid filling material (6), which tempers to a higher viscosity after complete filling and adheres to the outer surface of the elements (2,3,4) and the inner surface of the common sheath (5).

  • Patent number: 6973244
    Abstract: The invention relates to a cable comprising at least two elongated elements chosen from a group consisting of steel tubes (1, 2), optical fibre cables (3), electrical cables (4), and combinations thereof, arranged side by side within a common outer cover (5) along the length of the line and where at least one of the elongated elements (1, 2) has a passive metal outer surface, said outer cover (5) allowing entrance of corrosive agent to the interstices between elements, characterized in that at least one of the elements (1,2) with passive metal outer surface is provided with an outer layer (1A, 2A) formed of a material with open structure for water passage and having controlled thickness.
