Sludge Tank - MARPOL Minimum Capacity
Minimum sludge-tank capacity per MARPOL Annex I Reg. 12.1 - based on daily fuel consumption and voyage length between ports of sludge landing.
K factor (MARPOL)
0.0100 -
Minimum capacity
10.50m³
Formula, assumptions, and limits
$$V_{sludge} = K \cdot C \cdot d$$
K = 0.01 for vessels burning HFO without purifiers, 0.015 for HFO + purified (higher because purifier sludge produced), 0.005 for MDO/MGO only.
