The studies are carried out using RANS-based CFD to analyse defined flow conditions. The output can include hydrodynamic loads on marine structures, detailed flow field information in specific regions and motions arising from the interaction between the structure and the water.
Maritime and offshore engineering
Detailed flow studies for ships and offshore constructions
Get detailed hydrodynamic studies that support ship and offshore design, modification work and investigation of in-service issues.
Detailed flow studies support designers and engineers in early vessel projects and when modifying an existing ship or offshore structure. The need typically arises when the hydrodynamic behaviour must be better understood before design work can proceed.
When detailed hydrodynamic issues need clarification
The studies are also relevant when flow-related problems appear after a ship or offshore structure has entered operation. In these situations, the studies provide a clearer basis for investigating the issue and for continuing design or modification work with greater confidence. The service is part of our expertise area Maritime and offshore engineering.
Challenges
When hydrodynamic behaviour is unclear, it affects design work and investigation of operational issues.
Local flow conditions are insufficiently defined
If the flow around specific areas such as propellers, appendages or hull details is not described in sufficient detail, the technical assessment will be incomplete.
Changes introduce uncertain hydrodynamic effects
Changes to components or configurations can affect flow patterns in unpredictable ways, making it harder to assess their impact before implementation.
Observed effects are difficult to attribute
Operational issues such as vibration or resistance may involve multiple interacting flow mechanisms, making it difficult to determine the underlying cause.
Benefits
Get clearer basis for design work, modifications and investigation of operational issues
Create a stronger basis for design work
The studies provide designers and engineers with a clearer basis for addressing hydrodynamic questions in early project phases and during modification work.
Support comparison of configurations
The studies enable comparison of selected configurations or components under defined conditions, supporting evaluation of alternatives in a structured way
