A 36 inch cooling water reducer suffering severe external corrosion was repaired using Futurewrap Glass/LT composite repair.  The repair was completed within 11 days allowing the pipework to be re-pressurised returning the pipework to its original integrity.

This case study summarises the pressure testing and analysis performed to determine the γLCL for the Futurewrap Glass/LT repair system on carbon steel pipework where the surface preparation is to Sa2.5.

A 8 inch produced water pipework suffering internal corrosion was repaired using Futurewrap Glass/LT composite repair.  The repair was completed within 2 days allowing the pipework to be re-pressurised returning the pipework to its original integrity.

A drilling mud was repaired using Futurewrap Glass/LT composite repairs.  The repairs were completed within 3 days reinstating the integrity of the tank.

A 16 inch crude oil separator line suffering internal corrosion was repaired using a Futurewrap Glass/HT composite repair.  The repair was completed within 3 days allowing the pipework to be re-pressurised with the pipework returned to its original integrity.

A 36 inch section of produced water caisson was repaired using Futurewrap Carbon/Aquasplash composite repair.  The repair was completed within 14 days allowing the pipework to be re-pressurised and  returning it to its original integrity.

A foam mud tank was repaired using a Futurewrap Carbon/LT composite repair.  The repairs were completed within 3 days reinstating the integrity of the tank.

A 4-inch seawater flowline suffering internal corrosion was repaired using a Futurewrap Glass/LT composite repair.  The repair was completed within 3 days allowing the pipework to be re-pressurised with the pipework returned to its original integrity.

A 8 inch stub (carbon steel) was suffering from external corrosion. The external corrosion was sufficiently severe that the remaining wall thickness would not provide sufficient strength to withstand the acting structural loads. It was proposed to use a Futurewrap Structural composite repair to reinstate the strength of the 8 inch stub.

A 8 inch produced water pipework was suffering from internal corrosion. Localised internal corrosion had caused severe pitting which was expected to do through wall within months.

A 10 inch mixed HP flare line was suffering from external corrosion. The external corrosion was so severe in places that the design premise was to assume a through wall defect.

A 24 inch manifold section of export pipework was suffering from internal corrosion. Further internal corrosion was expected to occur and therefore a composite repair solution was sought
