Simulate complete marine systems including free surface flows and 6-DOF motion
Computational methods based on potential flow theory and empirical correlations have long been used to design marine vessels. In recent years, high-fidelity CFD methods have matured and the industry has been quick to adopt the technology to keep pace with the changing industry.

  • CD-adapco offers specific simulation ools and procedures in STAR-CCM+ to fit the needs and requiremenst of the marine and offshore industry. Shown here is a wind and wave loading analysis on an offshore platform.

The sole use of traditional design methods like tow tanks and cavitation tunnels is no longer feasible in an industry where shorter design times, faster time to market and identification of problems at an early stage are becoming paramount.

Substantial improvements in CFD technology have made its application in the marine sector an indispensable supplementary tool to traditional experimental and computational design methodologies. The key aspect of modern design lies in successfully analyzing different designs and identifying the most optimum designs before even stepping into the test rig, thereby reducing time/cost while effectively optimizing the design and numerical simulation offers the solution.

CD-adapco has a been providing state-of-the-art flow, thermal and stress simulation solutions to the marine industry for more than a third of a century. From large shipyards to suppliers of small components, the use of our simulation technology has become a standard feature in marine design and safety assurance process.

Using our flagship software, STAR-CCM+, our customers have been able to tackle some of the most demanding problems of the marine industry, allowing engineers and designers to accurately predict the operation of different designs in operation, before budget is committed to the construction of expensive prototypes.

While simpler methods may be suitable to optimize a single component on its own, CFD offers the ability to account for the interactions of all components of a system (ex: hull, propeller, etc.).

STAR-CCM+ offers a single-integrated environment to go from CAD to results in a streamlined manner, allowing the engineers and naval architects more time to concentrate on improving the design using the numerical results and spend less time setting up propulsion and steering system and other appendages) in full scale and under realistic conditions. the simulation. Our simulation capabilities can help in the following areas for the marine industry:

  • Ship keeping
  • Slamming and Sloshing
  • Marine Propulsion
  • Cavitation analysis
  • Wave and wind loading
  • Oil & pollutant dispersion

With easy-to-use meshing tools like Overset Mesh & Automated Meshing, advanced and well-validated physics capabilities including VOF & 6-DOF methods and state-of-the-art post-processing and optimization capabilities all within a single package, STAR-CCM+ offers a one-stop shop for all the simulation needs of the marine industry.
