New CRP Subsea tech targets better stability on cables

CRP Subsea has launched a new subsea Motion Stabiliser technology, said to be designed to protect cables, umbilicals and flowlines from motion instability and damage from uncontrolled movement.

According to CRP Subsea, engineered to mitigate instability in both axial and lateral directions, the Motion Stabiliser design includes customisable fins that anchor into the seabed increasing overall resistance.

It incorporates the company’s Uraduct and Tri-strakes materials and designs and is supplied in two lightweight halves, which are banded together during pipelay deployment operations, removing the need for a secondary installation vessel.

Fins placed along the length of the stabiliser are custom-designed for varied soil conditions, ensuring they effectively embed into the seabed and create the required resistance per metre of the system, the company stated.

This is said to have proved to give significantly increased resistance compared to cables, umbilicals and flowlines without stabilisers.

“Through ongoing collaboration with our customers, we understand that on-bottom stability, axial walking and lateral sliding can be real issues,” said Paul Louvain-Walters, business group manager (Elastomers) for CRP Subsea in Skelmersdale, England.

“Irrespective of the phenomenon causing the instability, our latest innovation Motion Stabiliser is designed to control movement, keeping cables, umbilicals and flowlines in their laid location where desired or allowing movement when needed, reducing the risk of damage or undue stresses.”
