A 20” nozzle coming off a produced water caisson on a North Sea offshore installation, had sustained external corrosion resulting in a through wall defect. A weld repair had been affected but was deemed not ‘fit for purpose’ and so the client required an Engineered composite repair to reinstate the integrity of the pipework.
The scope of work was to provide an engineered design, with 2 year repair lifetime, Technowrap™ trained personnel and Technowrap 2K™ materials to affect repair.
With the location of the defect the repair entailed a patch repair on the caisson and a full circumferential repair on the 20” pipework which included encapsulation & landing on a flange.
Technowrap materials were rapidly pulled together and Technowrap™ supervisor & Technowrap Technician were mobilised, at short notice, so that the Engineered Technowrap 2K™ repair could be implemented to allow the client to go back online & minimise the asset downtime.
