Savings estimator
How much more could your vessel be saving?
A 30-second screening estimate. Pick a vessel, choose the technologies you are considering, and see the indicative range, then send it to us for an accurate CFD assessment.
Your vessel
≈ 17,934 t/yr fuel at 50% load over 230 sea days

Fuel saved per year686 – 1,996 t
Bunker cost avoided$384k – $1.12M/yr
CO₂ avoided2,161 – 6,289 t/yr
Indicative payback0.5 – 1.3 yrs
Screening estimate only. Bunker cost avoided assumes VLSFO at $560/t. Real gains depend on hull form, wake field, loading condition and route, and can only be confirmed by CFD on your vessel. CO₂ uses IMO tank-to-wake factors. Not a performance guarantee or a commercial offer.
Indicative estimates only. The figures above are a screening estimate based on typical performance ranges for each technology class. They are not a prediction for your vessel. Actual savings depend on hull form, wake field, loading condition and route. Before any retrofit, SEMS runs a full CFD study on your vessel to quantify the exact savings, and confirms them with in-service performance monitoring. Nothing on this page is a performance guarantee or a commercial offer.
