Corrosion Allowance in Splash Zone
Corrosion Allowance in Splash Zone
(OP)
Hi,
I have to design a clamp system in the splash zone of a platfrom. The clamps are coated with 1.5 - 3 mm of epoxy coating.
Do I have to consider the corrosion allowance in the design?
Wath is the amount of corrosion per year and wath are the reference standards?
Thanks.

This depends on the design life of your clamps. Your epoxy coating may not last longer than 5 years without maintenance...
RE: Corrosion Allowance in Splash Zone
In the preliminary design i selected 5mm of corrosion allowance. Is this value acceptable?
RE: Corrosion Allowance in Splash Zone
normally you find that value.

Its the type and thickness of coating on the clamp for the splash zone that you need to consider.

1 with brace welded on the platform leg and
1 clamped on platform leg with neoprene as internal protection coating.
The client considered this section of riser not cathodically protected and suggested a corrosion allowance of 5 mm to be considered in the design.
Is this a reliable approach?
RE: Corrosion Allowance in Splash Zone
Deepray, as you can see, its a pretty common criteria.
