Check ODME cargo discharge rate against the MARPOL Annex I Reg. 34 limits: ≤ 30 L oil content per nautical mile, ≤ 1/30 000 of total cargo, en route, > 50 nm from nearest land.
Formula
$$ q_{nm} = \frac{\text{ppm} \cdot \dot V}{v}, \quad \frac{V_{oil,\text{voy}}}{M_{cargo}} \leq \frac{1}{30000} $$Symbol legend
| Symbol | Meaning | Unit | Source |
|---|---|---|---|
| $ppm$ | Oil content at outlet | ppm | ODME sensor |
| $\dot V$ | Discharge volumetric flow | m³/h | flowmeter |
| $v$ | Vessel speed over ground | kn | GPS/LOG |
