SCOUR PREVENTION
That’s all set to change as Lowestoft- based Scour Prevention Systems Ltd has a patented and proven solution to preventing and remediating scour around offshore structures and over cables, which is recognised as a significant problem across the offshore and subsea industries.
UNIQUE SOLUTION The clever bit? Scour Prevention’s unique solution consists of a matrix of end-of-life vehicle tyres connected and laid on the seabed. By disrupting the flow of water, the tyre-mattress captures and retains sediment within the tyres. Due to the shape and density of the tyres, they fill with natural seabed material to form a stable protective layer, preventing further scouring of the seabed wherever the mats are placed.
Offshore windfarms in the North Sea area are particularly prone to scour due to its shallow depths
Offshore windfarms in the North Sea area are particularly prone to scour due to its shallow depths, sandy seabed and tidal currents. Scour Prevention’s design has been subject to robust trials including tank trials with the University of East Anglia, and the hydrodynamics laboratory of the IHLAB in Spain. Offshore trials have been undertaken on a Southern North Sea offshore windfarm and a cable/pipeline crossing in the Northern North Sea.
DEPLOYMENT The Scour Prevention tyre-mattress solution has already been deployed for remediating and preventing further scour around offshore wind foundations, protecting telecoms cables crossing subsea infrastructure, and preventing scour over subsea cables and pipelines. Typically, rock dumping is used to protect turbines and cables against scour, however there are challenges associated with this approach both environmentally and technically. Rock armour, as with concrete mattresses, can often cause secondary scouring around the edge of the rocks or concrete. This can often lead to additional protection required during the lifetime of the asset, which can be costly.
LIFESPAN Scour Prevention’s tyre-based solution not only lasts the lifetime of an offshore windfarm, it can be installed from a range of vessels using ROVs and can be lifted and removed for inspection, repair and final decommissioning.
