Abstract:
A power triad of an umbilical may be rotated during multiple transition lengths to position each power cable of the power triad equally at radial orientation over the length of the umbilical. A first portion of the umbilical includes the triad in a first radial orientation, a second portion of the umbilical includes the triad in a second radial orientation, and a third portion of the umbilical includes the triad in a third radial orientation. The triad is rotated a first one hundred twenty degrees from the first radial orientation to the second radial orientation during a first transition length. The triad is rotated a second one hundred twenty degrees from the second radial orientation to the third radial orientation during a second transition length. The use of three radial orientations along the length of the umbilical may reduce imbalances between the power cables of the triad.
