Abstract
Armored steel wire is an important strength component of the umbilical, which can bear the load
of stretching and torsion in complex marine environment and can protect the central core. In or-
der to ensure the torsion balance and stress balance of umbilical, the armored steel wire is usually
designed as two or more layers and wound outside the central core in opposite directions. In this
paper, a theoretical design method of armored steel wire of umbilical is discussed, and a theoreti-
cal model of double armored umbilical is established. The results show that the spiral angle and
diameter of the
