Simplified owner / charterer split of SEEMP Part III corrective-plan costs under BIMCO’s 2022 CII Operations Clause.
Formula
$$ \text{Share}\text{charterer} = \min!\left(1,\ \max!\left(0,\ \frac{I\text{actual} - I_\text{planned}}{I_\text{actual} - I_\text{required}}\right)\right) $$
Symbol legend
| Symbol | Meaning | Unit | Source |
|---|---|---|---|
| $I_\text{actual}$ | Attained CII under charterer’s voyage orders | g / (dwt·nm) | DCS |
| $I_\text{planned}$ | Owner-warranted Attained CII | g / (dwt·nm) | charter-party |
| $I_\text{required}$ | Target CII | g / (dwt·nm) | MEPC.337+338 |
The clause covers time charters. Voyage charters use a different allocation because the owner retains operational control. Real clause text includes notice periods, safe-speed carve-outs, bunker-quality caveats, and exceptions for force majeure.
