Computational fluid dynamics services for the marine industry

Improve your vessels’ performance, safety and usability with the help of our CFD simulation services. You will get to make use of our vast marine industry competence.

We help you to develop aerodynamics and hydrodynamics both for new vessels as well as for retrofitting, while also taking the safety aspects into account. We have special expertise in the marine industry, which helps us in designing top-rate vessels

The hydrodynamics research we offer helps you to discover energy-efficient solutions for designing the hull and additional components, without forgetting maneuverability or sea keeping capabilities. Our aerodynamics research provides information on wind coefficients for the superstructures design, smoke concentration and the comfort level needed, thereby helping with implementing the appropriate plan.

We take safety into account in all our research. We make use of our solid experience on vessel behavior in different conditions and on the requirements set by the classification.

  • Hydrodynamics, energy savings and vessel usability
  • Aerodynamics, wind loads, smoke concentration
  • Safety and comfort, meeting the classification regulations, energy savings in ventilation and air conditioning, smoke ventilation during fires, gas leak scenarios, receptacle analysis in exhaust pipe gas explosions

Hydrodynamics and performance

Computational fluid dynamics can be utilized to find a way to improve the vessel fuel economy, which is highly dependent on ship resistance. Often, reducing the ship hull total resistance by just 1%, significant fuel savings are achieved.

Our computational fluid dynamics (CFD) services can be used for both new builds and retrofits to find solutions to improve the ship’s performance and operability. When using CFD, model tests are only needed for the final design, allowing a shorter timeline for your development project.

The highest potential for fuel saving with streamlined vessel is found in friction between water and hull surface, which could be reduced with air lubrication. The system can be optimized and validated with CFD simulations, helping to evaluate the investment of devices.

The pressure resistance can also be minimized by optimizing the ship as streamlined as possible, not forgetting the ship operability.

For retrofits, we offer plenty of alternatives to reduce the resistance contributed by pressure forces. Our CFD tools make it straightforward to compare different solutions and detect the most promising design modification.   

  • Bulbous bow performance analysis and improvement – speed influence detection
  • Elogrid for tunnel openings, evaluations for resistance and thrust performance
  • Fin stabilizer, alignment and recess impact analysis
  • Bilge keel, alignment and friction analysis
  • Air lubrication, system optimization and validation for saving potential
  • Appendages, rudders, propellers – performance inspection and improvements
  • Duck tail, interceptors, head boxes etc. impact to ship resistance

Aerodynamics, safety and comfort

The model scale wind tunnel tests can be replaced by full-scale simulations using computational fluid dynamics (CFD), resulting in more accurate data of ship aerodynamics and better solutions for the superstructures.

  • Ship aerodynamics
  • Wind force and moment coefficients
  • Exhaust gas dispersion
  • LNG bunkering leak scenarios
  • Wind comfort and safety at outer decks
  • Helideck wind conditions

Our CFD simulations for marine aerodynamics are used for several purposes. If you are starting a new-build, we can determine the wind force coefficients to find the thrust demand and wind limits for selected thrust capacity.

Smoke dispersion can be analyzed as well, to ensure the funnel design performances keep the smoke concentrations below the limits allowed at the outer decks, ensuring a safe working environment and increasing passenger comfort. Predicting the conditions on helidecks is another area where our CFD simulations can be utilized.

In retrofits, the simulations can help in cases where larger superstructure components are modified. The operability and safety issues can be evaluated with simulations, for example by comparing the situation before and after the modifications.

Feasibility studies

The feasibility studies are needed in vessel concept design stage to ensure that performance and operability are on the level required. Computational fluid dynamics is the most effective way for testing and optimizing concepts.

  • Concept design
  • Feasibility study
  • Design optimization

Using computational fluid dynamics (CFD) at the early stages of concept design helps to reach accurate information of the overall feasibility of the potential new design alternatives and concepts to be utilized in the vessel.

With our fluid dynamics simulation tools, we can also assist you in ensuring the operability of the vessel by performing simulations in all possible conditions and places where the vessel would operate.

Additionally, we can check the performance and economy of the vessel. Comparing different solution alternatives will help you to reach the optimal design.
