MMC engineers use advanced software tools to predict primary hydrodynamic parameters for complex motions and response analysis. ANSYS DesignModeler software, Rhino3D, MultiSurf, or other solid and surface design tools are used to create models of mooring systems.

For most mooring and anchoring systems, we use the ANSYS AQWA three-dimensional linear diffraction/radiation panel code. Used for fast, efficient simulation and analysis of single or multi-body marine structures, AQWA solves the coupled diffraction problems in six degrees of freedom. The program includes Morison elements that can be used to analyze and simulate complex mooring systems and riser systems. MMC uses ASYS AQWA for hydrodynamic assessment of all types of offshore and marine structures, including:

  • SPARs
  • Ships
  • FPSOs
  • Renewable energy devices
  • Semi-submersibles
  • Breakwaters
  • Tension leg platforms

MMC has extended the capabilities of AQWA by the use of an extensive set of user defined functions and scripts, and we have incorporated AQWA into larger software systems for design optimization.

For detailed numerical analyses of fluid flow problems, MMC uses ANSYS CFD programs such as Fluent and CFX, because of their acknowledged accuracy and because motion and pressure results can be transferred to ANSYS structural mechanics products.

For structural analyses of critical components MMC uses the ANSYS Structural family of finite element analysis tools.
