FoundOcean – which runs its operations base from Livingston – is now trialling its new range of marine-growth prevention units on a wind turbine jacket in Liverpool Bay.
After having installed more than 26,000 similar units on oil and gas platforms in south-east Asia and in other global markets, FoundOcean is seeking to open up a new market in UK renewables platforms.
Andy Venn, Marketing Director, FoundOcean, said: “These latest units for the renewables market are the beginning of an extended trial period on the jacket, following successful results of an earlier version of a marine-growth prevention unit fitted in 2013.
“To demonstrate the effectiveness of controlling marine growth with this established technology, we have installed two units on a jacket structure in the Liverpool Bay area.”
As well as adding to the static weight of a structure, marine growth can interfere with the systems for corrosion protection and increase the hydrodynamic loadings associated with wave and current actions on the structure.
These increased stresses can result in unnecessary and avoidable fatigue damage which in turn can reduce the operational lifespan of the asset. Hence many offshore standards address the control of marine growth, particularly with regard to the inspection of marine growth build-up and its removal.
Venn added “The advantage of this technology is that it is constantly preventing the build-up of the microbial slime which is commonly the precursor to much more damaging hard and soft marine growths like crustaceans and seaweed.”
MGP units are offered in two versions, wave driven for splash zone applications, and current driven for controlling marine growth subsea. By eliminating the need for divers to periodically remove marine growth, numerous asset managers around the globe have found that the technology is one of the most cost-effective and safest life extension solutions on the market.
