DNV-RP-B401

Cathodic protection design — sacrificial anodes

DNV-RP-B401 is the recommended practice for sacrificial-anode cathodic-protection design. Ask Deckhand to size the anodes for a structure and get the current demand and anode mass.

What you can ask it to do

  • Work out current demand from surface areas, coating breakdown and design life.
  • Size the sacrificial-anode mass and number, and check the final-current capacity.
  • Apply it to a jacket, manifold, monopile, FPSO hull or pipeline.

Questions

What does DNV-RP-B401 cover?

The design of sacrificial-anode cathodic-protection systems for offshore structures — current-density demand, coating breakdown factors, anode mass and current-capacity checks over the design life.

What structures can Deckhand size?

Jackets, subsea manifolds, offshore-wind monopiles, FPSO hulls and pipelines (the pipeline case uses DNV-RP-F103 for anode spacing and reach).
