51316-7303- Optimization cathodic protection design for offshore platform: Solution for the contradiction of big initial and small mean current density by wing section sacrificial anode

Picture for Optimization Cathodic Protection Design for Offshore Platform: Solution for the Contradiction of Big
Available for download

There is big initial and small mean current density for offshore platforms. Sometimes the former is twice of the latter. DNV-RP-B401 suggests minimizing anode size and density. NACE-RP-0176 recommends utilizing more anodes. This paper introduces a new method by wing section sacrificial anode with large surface area in the initial period.

As everyone knows, there is the contradiction of big initial and small mean current density for offshore platform, sometimes the former is twice of the latter. DNV-RP-B401 suggests minimizing the anode size to meet the bigger initial current density, and NACE-RP-0176 recommends utilizing utilizingutilizingutilizingutilizing utilizing more anodes. This paper introduces a new method to address this problem by wing section sacrificial anode with large surface area at initial period. Experiment results showed that the wing section sacrificial anode can output 30-40% more current density than the long slender stand-off, while L ≥ 4r.

Key words: downloadable, wing section, sacrificial anode, big initial current, small mean current, optimization, cathodic protection, CP design, offshore platform
