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.
Specimens were pressurized until the failure of the patch and endured even up to 64 bar. The test results are currently under review by DNV GL and the technology is pending approval.
