Computational fluid dynamics
Computational fluid dynamics (CFD) for offshore and marine engineering questions where flow detail matters. We use it alongside hydrodynamic analysis and engineering judgement to investigate wave interaction, green water and damping.

- Assessment of water reaching the deck and interaction with the vessel geometry.
- Wave impacts and wave loading on marine structures.
- Free-surface behaviour where a more detailed flow description is needed.
Damping and response
- Damping assessment to inform the representation of floating systems.
- Investigation of flow mechanisms that influence motions and hydrodynamic loading.
- Connection of CFD findings with the wider response model.
A model built around the question
- Define the physical question, the conditions to represent and the outputs needed for the engineering decision.
- Select geometry, numerical domain, mesh and time resolution around the agreed scope.
- Review numerical sensitivity and compare with relevant theory, available measurements or model-test evidence.
From calculation to interpretation
- Interpret flow fields, free-surface behaviour and time histories in their engineering context.
- Document assumptions, modelling choices and limits of the assessment.
- Use our computing resources in France for demanding study and research workloads.
Typical deliverables
- CFD modelling basis and numerical setup
- Flow, free-surface and load visualisations
- Green-water or damping assessment reports
- Numerical sensitivity and interpretation notes

Planning your engineering scope
When is CFD useful in an offshore study?
CFD can help when local flow, wave impact, water on deck or viscous effects matter to the question. We discuss whether a CFD study, a response model, model testing or a combination offers the appropriate level of detail.
How does CFD connect with other disciplines?
CFD results can inform hydrodynamic assumptions and structural loading. The interfaces and interpretation are agreed with the engineers responsible for the wider system.
