Stripping Efficiency Check
Verify stripping achieves the Annex II limit of 75 L per Cat Y/Z tank (100 L for existing ships, 75 L for new/Cat X).
MARPOL limit
75L
Compliance
Compliant (≤ 75 L)
Formula, assumptions, and limits
Measured via recertified stripping test as per Annex II. If residue exceeds limit, ship must prewash with dedicated wash-water and discharge residues ashore. Stripping efficiency is a class-certified figure for the ship, not per-cargo.
