Estimate tank-cleaning machine programme time for a single cargo tank using butterworth/washing-machine coverage rate - typical ISGOTT 6 figure.
Formula
$$ t = \frac{A}{\dot V_{machine} \cdot k_{cov} \cdot n} $$Symbol legend
| Symbol | Meaning | Unit | Source |
|---|---|---|---|
| $A$ | Tank internal surface area | m² | capacity plan |
| $\dot V$ | Machine wash flow | m³/h | Butterworth spec |
| $k_{cov}$ | Coverage factor | m²·h/m³ | ISGOTT tables |
| $n$ | Machines per tank | - | cleaning plan |
