Step 3 — Structure Geometry
Select the sheet pile model — shared across all sections. Then define one or more chainage sections, each with its own levels. No. of piles and lengths are calculated automatically.

Step 4 — Structural Surface Area (SSA)
Calculated from Step 3 geometry. SSA per exposure zone = Pile Length × Coating Area (m²/m) × No. of Double Piles.
Step 5 — Current Demand
Protection current at Initial, Mean and Final stages. Current = Effective SSA × Current Density, where Effective SSA accounts for coating breakdown over the design life.
Step 6 — Anode Sizing & Selection
Size the anode to meet the design current from Step 5. The anode cross-section is rectangular; the equivalent cylinder diameter is used for resistance calculations per NACE/DNV.
