Case Study: Coastal Coarse Screen Refurbishment

Refurbishment of UK Coastal Nuclear Power Station Coarse Screens


UK Nuclear Power Station

Scope of Work

Remove existing failing coating and reinstating new coating system to provide at least 36 months protection against corrosion, marine life attachment and sea water tidal variances.


Low VOC, high solids, modified epoxy barrier coating and a high activity, self polishing antifouling.


Carbon Steel

Coating System

The coarse screens were stripped of the their existing coating followed by grit blasting to a cleanliness standard of Sa2½ in accordance with ISO 8501-1:2007. The modified epoxy barrier coating was applied by brush and spray methods to ensure a minimum dry film thickness of 1mm followed by the brush and spray application of the antifouling to a minimum dry film thickness of 75 microns.

Coating Details

The low VOC, high solids, modified epoxy barrier coating will continue to cure when immersed in water and has excellent cathodic disbondment resistance. It is primarily designed for use in offshore splashzone maintenance, where its continued cure under immersed conditions makes it ideal for coping with tidal movements and surges. The high activity, self polishing antifouling controls shell and weed fouling for service periods up to 60 months and complies with IMO Antifouling Systems Convention.
