SCOPE OF WORK
The repair design was performed in compliance with API 653 and ASME PCC-2 standards. It was not possible to step on the roof, the work was conducted out of a basket man lifted with a crane and supplied by the client. Protection and safety was required including a charcola mask for respiratory protection and a height harness.
The tank roof reinforcement was performed following 4 main steps:
- Surface preparation and cleaning: The surface preparation was performed manually. No electrical or spark productions work was allowed. Once the surface preparation was done, hygrometric conditions were checked and the complete area was cleaned with acetone.
- Filler and steel plate application: 3X filler was applied on small holes and then sealed using steel plates (previously prepared on both side) covered with 3X specific filler. The steel plates were holded using magnets until the filler is cured.
- Wire mesh application: Wire mesh was applied on the large defected areas and covered with 3X filler before patches application.
- Composite patching reinforcement: First layer of R3X95 resin was applied on the entire surface. Then patches of Kevlar® fiber with R3X95 resin were applied, 9 patches of 3 layers each one were necessary to cover the complete defected area meaning a total of 27 patches installed.
