Award-winning technology developed in the east of England is to be presented as a cost-saving solution for North Sea decommissioning at a major industry conference in Aberdeen today.

Scour Prevention Systems will showcase how its patented scour prevention mats – using end-of-life automobile tyres – offer alternative effective protection for decommissioning oil and gas pipelines to delegates at the Decommissioning: Technology Innovation Platform event hosted by Decom North Sea and the Oil and Gas Innovation Centre.

The company, based at Orbis Energy in Lowestoft is one of 10 companies chosen to present technology that has the potential to help companies achieve the 35% decommissioning cost reduction targeted by the Oil and Gas Authority (OGA)

Scour Prevention Systems’ John Best and Alistair Punt will explain to delegates the potential savings of tyre mats compared to traditional methods such as concrete mattresses or rock armour.

They take less time to install, have no threat of pipeline damage and need no direct remedial works. Furthermore, with an increasing number of cables of offshore wind being installed, the mats provide an effective crossing bridge at an interface with a decommissioned pipeline.

Best said: “When pipelines are being decommissioned, our mats’ design helps to reinstate seabed cover and leave the pipeline secure and protected in a non-obtrusive manner.

“The product effectively stablises the seabed over pipelines forming a secure protective layer, protecting the pipeline from exposure and damage, providing a cost effective and easy-to-install solution to pipeline decommissioning.

The mats have been trialled and successfully demonstrated in the North Sea and used to remediate and prevent further scour around offshore wind foundations, and protecting telecoms cables subsea infrastructure.

Other speakers at today’s event include Colette Cohen, chief executive of the Oil and Gas Technology Centre, and Jim Christie, OGA head of decommissioning.
