Pipeshield secure East Anglia ONE scour protection contract

5th Mar 2019

Pipeshield International Limited are very proud to have been awarded the contract to supply the scour protection for the East Anglia One offshore windfarm by leading offshore construction company DeepOcean.

Over 300 bespoke fronded concrete mattresses have been manufactured at the port of Great Yarmouth within close proximity of the deep water berth.

Fronds are a dense carpet of strands, like a bionic seaweed, woven together to create a system which slows down the sediment on the seabed, causing it to fall and create natural burial.

The fronded concrete mattresses or FCM’s, are of Pipeshield’s own design and utilises their specialist three part frond system. A recyclable protective cover protects the system during storage and transportation. This is removed prior to installation. Once the mattress is in place on the seabed a detachable safety net is pulled away releasing the frond system and starting the burial process.

The frond system is fixed to one of Pipeshields 6m x 3m concrete bi-flex mattresses with their patented nose to notch block design (N2 Edge). This block design is proven to provide up to three times more edge stability compared to a standard block design.

Pipeshield’s General Manager David Blake said, “We are delighted to receive the award by DeepOcean for the supply of the scour protection for EA1. To be part of the first zone of such a significant project is fantastic. Local content has been discussed a lot during contract negotiations, so it is particularly nice that we have been able to utilise both locations for this project, Lowestoft (Design & Contracts) and Great Yarmouth (Manufacture & Delivery).
