Predict and Control Your Fleet’s Carbon Compliance Costs
OceanOpt’s Fleet Cost Simulator is a free tool that instantly allows you to model the financial impact of EU ETS, FuelEU, and IMO GFI rules, giving you a 5-year forecast and breakdown per vessel or fleet.
Frequently Asked Questions
1. What is the OceanOpt Fleet Cost Simulator?
It’s a practical tool for shipowners and operators to see how upcoming carbon and fuel regulations will affect running costs. The simulator covers EU ETS, FuelEU Maritime, and IMO’s GHG rules, giving you a clear financial picture of what’s ahead.
2. How accurate are the projections?
Forecasts depend on the data you put in, but the simulator is built on current regulation texts, real carbon prices, and standard fuel consumption models. It’s regularly adjusted as rules or market prices change, so results stay aligned with reality.
3. Which regulations are included?
At the moment, the tool reflects three main frameworks:
- EU ETS (carbon allowances in Europe)
- FuelEU Maritime (fuel intensity requirements)
- IMO GHG Fuel Intensity rules (global efficiency standards)
4. Who benefits from using it?
Anyone making operational or budget decisions in shipping — owners, technical managers, charterers, or consultants who need to understand exposure and plan compliance strategies.
5. What data do I need to get started?
Basic fleet details: vessel type, fuel used, average consumption, routes (inside/outside EU), and if relevant, things like ice class. More detail means a sharper forecast.
6. Can I test different fuel or compliance options?
Yes. You can compare scenarios such as staying on conventional fuels vs. switching to biofuels or planning retrofits to see how costs change.
7. Does it break results down by vessel?
Yes. Each vessel in your fleet gets its own cost estimate, making it easy to spot which ships carry the biggest compliance risk.
8. How does the 5-year outlook work?
The simulator looks ahead using published regulatory phase-ins and current allowance price assumptions. It helps you see how costs may build up and gives a basis for budget planning and investment decisions.
9. Is it free to use?
The online simulator is free to try. For deeper fleet studies, scenario comparisons, or tailored recommendations, OceanOpt offers advisory services.
10. Can I get detailed guidance beyond the results?
Yes. After running your fleet through the tool, you can request a consultation to discuss strategies like pooling, offset purchases, or fuel transition planning.
11. How often is the simulator updated?
Whenever there’s a regulatory change or a shift in the carbon/fuel markets. The aim is to keep the numbers as close to market conditions as possible.
12. Does it help with reporting?
Indirectly, yes. The simulator produces key compliance data that can support EU MRV, FuelEU documentation, and IMO DCS submissions, making reporting easier.
