  • Patent number: 8919092
    Abstract: An SZ laying machine for umbilical/power umbilical is described. Starting from an input end the machine includes: a first die receiving and collecting a first set of elongate elements substantially rectilinear from respective supplies of elongate elements, a second static die which receives and collects a second set of elongate elements substantially rectilinear from respective supplies of elongate elements and this second set is closed together with the first set into an assembled bundle, at least one supporting means which keeps the assembled bundle radially in place; a revolving device able to torsional rotate the bundle back and forth in an oscillating SZ manner, and a tape or band winding apparatus which in immediate proximity to the revolving device applies band or tape circumferentially onto the SZ laid bundle of elongate elements.

  • Patent number: 8304651
    Abstract: An umbilical includes a number of fluid pipes, electric wires and/or optical conductors, filler material located at least partially around and between the fluid pipes and the wires/conductors, and they are collectively gathered in a twisted bundle by a laying operation. The umbilical further includes a protective jacket that encompasses the fluid pipes, the wires/conductors and the filler material, and at least one load carrying element located in the cross section of the umbilical. Optionally, one or more fluid pipes constitute load carrying elements. The fluid pipes, the wires/conductors, the filler material and the at least one load carrying element, are alternately laid, i.e. by continuously alternating direction, in the entire or part of the longitudinal extension of the umbilical.

  • Patent number: 8270793
    Abstract: A power umbilical is shown that comprises a number of power cables (4) to transfer large amounts of electric power, optionally electric wires and/or optical conductors (5), filler material (2, 3) in the form of rigid elongated plastic elements that are located at least partially around and between the power cables (4) and the optional wires/conductors (5), and they are collectively gathered in a twisted bundle by means of a laying operation. A protective jacket (1) encompasses the power cables (4), the optional wires/conductors (5), the filler material (2, 3), and at least one load carrying element (6) predetermined located in the cross section of the power umbilical. The power cables (4), the optional wires/conductors (5), the filler material (2, 3) and the at least one load carrying element (6), are alternately laid, i.e. by continuously alternating direction, in the entire or part of the longitudinal extension of the power umbilical.

  • Publication number: 20110185559
    Abstract: An SZ laying machine (1) for umbilical/power umbilical is described. Starting from an input end the machine includes: a first die (3) receiving and collecting a first set of elongate elements (10a-I10c) substantially rectilinear from respective supplies (11) of elongate elements, a second static die (4) which receives and collects a second set of elongate elements (1 Od-I Of) substantially rectilinear from respective supplies (16) of elongate elements and this second set is closed together with the first set into an assembled bundle (18), at least one supporting means (5) which keeps the assembled bundle (18) radially in place; a revolving device (6) able to torsional rotate the bundle (18) back and forth in an oscillating SZ manner, and a tape or band winding apparatus (7) which in immediate proximity to the revolving device (6) applies band or tape circumferentially onto the SZ laid bundle (18) of elongate elements (10a-10f).
