Abstract

Flexible risers are used to link subsea pipelines to oil and gas production floating installations. These risers are multilayered pipes formed by an inner flexible metal carcass surrounded by polymer layers and spiral wound steel ligaments, also known as armor wires. In this riser, the armor wires sometimes break during installation or due to mechanical fatigue. Some methods have been proposed to monitor the armor integrity. However, until now there is not a practical method that allows the automatic nondestructive detection of individual armor wires rupture. In this work, a very effective method for the automatic detection of armor wires rupture using Magnetic Barkhausen Noise and clustering methods is presented.
