Is your ship’s exhaust going where it shouldn’t?

Understand, solve and optimise your exhaust problems with CFD: from air quality and heat to hull staining and underwater exhaust.

Exhaust problems are not always visible on the drawing

You may be dealing with:

Exhaust gases reaching air intakes or accommodation areas
Unwanted smells or poor air quality on deck
Soot and staining on the hull
Excessive heat around structures or equipment
Unexpected exhaust behaviour around the waterline
Problems with underwater exhaust
A design that needs to be changed to meet project or regulatory requirements

Computational Fluid Dynamics (CFD) lets you investigate what is happening, before construction or when a problem already exists.

What can we help you solve?

- Exhaust dispersion: See where exhaust gases travel under different wind, flow and operating conditions.
- Air quality & recirculation: Investigate whether exhaust gases can reach cabins, ventilation systems, air intakes or working areas.
- Hull staining: Understand how exhaust interacts with the flow around the hull and identify configurations that can reduce soot deposition.
- Underwater exhaust: Simulate the interaction between underwater exhaust, the vessel and surrounding water to understand where exhaust gases travel.
- Heat & temperature: Assess temperature distribution around exhaust outlets, structures and nearby equipment.
- Exhaust design & optimisation: Compare different outlet positions and configurations before committing to costly changes.

Case study: Solving Exhaust Gas Propagation Problems

Femto uses CFD to investigate exhaust dispersion around ships, including its interaction with wind, waves and cabin air intakes. The analysis helps identify potential problems and optimise exhaust design before or after they occur.
