Flexible Riser Inspection

Flexible Risers are pipes made of a carefully designed assembly of alternate layers of steel wires and thermoplastic materials that can move with respect to each other. Due to the multi-layer design, it is difficult to inspect all components especially the mid wall defects. Innospection has designed and developed a high technology Flexible Riser Inspection Tool for monitoring the integrity of flexible riser layers.

The anticipated concerns of the flexible riser operators are defects such as cracks, corrosions, erosion and fatigue in the different layers of the wires under various tensional stress levels. The inspection techniques currently available in the market are able to inspect only the near side layers for wire disruptions while the far side layers remain uninspected.

As a result, Innospection has designed and developed a unique high technology Flexible Riser Inspection Tool that employs the Magnetically Biased Eddy Current technology. This Flexible Riser Inspection Tool focuses on corrosion and crack detection at the armoured wire layers and if in place, at the Zeta wires. A variety of sensors analyse the condition of the flexible risers with the capability of data comparison for conditioning monitoring.

The external inspection tools are capable to be supported by Remote Operated Vehicles (ROV) over large distances. The internal inspection solution focuses in the inspection of the external non-accessible area.
