Maritime & Subsea

Hydrodynamic analysis is an important application in the marine sector and in industries that deal with equipment that is used in water. Hydrodynamic analysis using Computational Fluid Dynamics (CFD) helps in determining and computing laminar, turbulent, steady state and transient hydrodynamic motions with highest precision.

Services We Provide

Polytec offers advanced flow calculations and CFD related services to the maritime and subsea sector, including:

  • Ships, boats, and other sea going vessels
    • Flow around vessel hulls and wave formation
    • Ship friction, form and wave resistance calculation
    • Appendage resistance calculation
    • Sea-keeping and added resistance in waves
    • Response amplitude operators (RAO’s)
    • Structural analysis
  • Thruster flow modeling and thruster/hull interactions
  • Slam and water impact loading
  • Subsea

Simulation Tools We Use

Our CFD consultants have considerable experience with the world’s best CFD tools such as:

  • ANSYS Fluent/ANSYS CFX: General CFD solvers for the most difficult and detailed problems in fluid dynamics
  • ANSYS Multiphysics: Advanced modeling involving coupled effects from diverse phenomena such as electromagnetics, fluid dynamics, non-linear structural mechanics, and more.
  • ANSYS Aqwa: Hull-wave interactions, boat dynamics, and issues important for solutions in the maritime industry
  • OLGA: Pipeline Transport and Multiphase Flows

Other tools we’re using includes::

In the right hands, these tools can solve the most detailed and challenging problems, whether it is fluid dynamics, structural mechanics, or multi-physical processes. And if these tools can’t get the job done, Polytec has the expertise to develop custom solvers and analysis techniques: we can meet any challenge.
