Abstract
A sandwich cable fairing designed for attachment to cables that are towed at operational speeds by marine vessels. The sandwich cable fairing has a design that combines layers of elastic and damping materials. The fairing dampens the vibration caused when the cable is towed at operational speeds. The outer layers (“bread”) of the fairing are made from a material with a modulus of elasticity that provides a desired amount of stiffness. In the middle of the sandwich cable fairing is damping layer made from a viscoelastic material. The layering of materials allows the fairing to have the flexibility to be crushed by cable equipment while maintaining the requisite stiffness to reducing flapping and the resulting vibration.
