MIDSTREAM & PIPELINES
Protecting Pipelines and Subsea Cables A world leader in subsea pipeline protection, Pipeshield is a well known and highly reputable brand in the offshore oil and gas arena and a leading source of knowledge on cable protection, scour prevention and protection within renewables.
rotecting cables, one faces the same issues as when protecting pipelines but they also encounter some unique challenges, especially where the cables are laid adjacent to the mono-piles of wind turbines and where nearby seabed velocities bring scour. Ensuring stability of the cables is essential. Concrete mattresses provide scour prevention and cable stabilisation and protection. The flexible nature of the block form ensures that the cables are conformed to the seabed contour. In the event of any localised scouring around the edge of the mattress, blocks will settle into the hole to prevent undercutting. To enhance scour protection a frond system can be fitted to the mattresses prior to deployment and then activated postinstallation. In the right conditions, the fronds will attract up to 1m of sediment over and around the mattress, providing enhanced
stability and improved protection.

Since Pipeshield was granted a patent for its N2 high performance mattress system, the company continues to innovate with three further patent applications, submitted for speed-loader systems, Rock mattress systems and ROV docking devices for the offshore mattresses installation frame. Pipeshield specialises in providing Mattresses in production
innovative solutions for underwater pipeline and cable protection. A further example of that can be seen in a purpose built multiple mattress handling frame. Pipeshield having designed the frame to install the complete mattress protection layout for Wind Farm monopole foundations in a single lift. Pipeshield is approved to ISO 9001:2008, 14001:2004, ISO 18001, is a supplier member to FPAL and has achieved the VERIFY status for its quality systems. Headquartered in Lowestoft, the company maintains manufacturing bases in England and Scotland and has established a permanent manufacturing arrangement in South East Asia and production experience in the Middle East, Indonesia, Canada and South Africa. Pipeshield has been working with some of the biggest companies in this arena to develop bespoke solutions to one of the most prolific problems renewable energy has to resolve: subsea.
