Hull fouling is one of shipping's oldest problems and one of its most underestimated cost drivers.
The Study
We analyzed performance data from 400 vessels monitored on the Oceanix platform between January 2023 and December 2025.
Average hull degradation in the study: 8.3% increase in fuel consumption at constant speed by month 18 post-drydock.
Key Findings
Economic Impact
At current VLSFO prices (~$620/MT), an 8.3% fuel penalty for a VLCC consuming 85 MT/day translates to approximately $1.9M in excess fuel cost per year.
