ROI Calculation Logic

Biofouling typically degrades large vessel fuel efficiency by 10-20%. This technology could improve annual fuel efficiency by ~5% (saving ~$0.65M/year per vessel, AI est.) and reduce dry-docking frequency by ~20% (from once every 5 years to once every 6 years, saving ~$0.07M/year in maintenance per vessel, AI est.). This totals an estimated annual saving of ~$0.7M (AI est.) per vessel. Including reduced healthcare costs from lower infection risks in medical devices, licensees could realize an estimated annual economic benefit of ~$1M (AI est.).
