Technology qualification with the DNV GL

Bristle resistance test video

Qualification tests were performed after DNV-GL issued the Statement of Feasibility for pipe and tank repairs for COMPA Repairs technology.  

COMPA team performed blister resistance tests according to standard ISO 24817:2017. There were 7 pipe specimens with damage in a form of the hole with the 15 mm in diameter. COMPA patches, containing 8 layers of glass and carbon fibres with epoxy resin, were applied by hand lay-up method to assure immediate watertightness.
