Antifouling paint depletion over a docking interval - self-polishing copolymer (SPC) loses ~5–15 µm/month depending on speed and trade area.
Formula
$$ t_{life} = \frac{\text{DFT}}{r_{polish}} $$Symbol legend
| Symbol | Meaning | Unit | Source |
|---|---|---|---|
| $DFT$ | Dry film thickness as applied | µm | paint schedule |
| $r_{polish}$ | Polishing rate | µm/month | paint datasheet |
