Wrap-type coating qualification for the splash zone
Wrap-type coating qualification for the splash zone
(OP)
Greetings,
Are there any standards to qualify wrap-type coatings for the splash-zone for offshore structures and risers?
The product alternative that I am looking at is a composite, consisting of a membrane wrap + resin.
I am aware of NACE TM0404 but it excludes such type of coatings.
Also,are there any general objections or resereves for such type of coatings for plattforms and risers?
It seems that the industry prefers to use continuously applied coatings as those covered by NACE TM0404.
Any reference towards information on coating selection that includes composites for splash zone in offshore oil and gas applications would be much appreciated.

The application I am looking at is for new construction, mainly for surface casings in shallow water wells.
The resin injection solution that you kindly mentioned is mainly used to repair heavily corroded pipelines or platform legs while in/service.

I can't think of a corrosion protection spec for wrapping, but a pressure containing repair would be governed by ISO 24817

I am trying to find pictures. These guys aren't having much luck in their application. https://www.hydro.org/document/shaft-coatings-and-...

Steve, thanks for the information.
Indeed, the wrap coating I am looking at seems to be a type of "light" version of wrapping non-metallic sleeves for corrosion repairs.
A first approach that I am thinking of is that it would probably be OK for the splash-zone application if it can be proven resistant to at least the same qualification requirements of NACE TM0404,or equivalent tests considering the different products covered by the standard.

RE: Wrap-type coating qualification for the splash zone
"In the splash zone, just above and below the water line, good corrosion prevention practice is characterized by minimizing the amount of structure in the water surface plane, and wrapping structural elements that pierce the water line with barrier materials such as Monel, Tideguard, and Splashstron. Properly applied, these materials are very effective at preventing corrosion in what is considered the area of a platform with the highest potential for metal loss. Nonstructural elements such as risers, sumps, well conductors, boat landings, etc. in the splash zone may be wrapped with barrier materials or protected with multi layered coating systems. All systems in the splash zone fall prey to the mechanical damage of wave action and boat impact."
