K-Epsilon provides aero structure solution to  to help flexible membrane industry 

-Deeper, further, and in more extreme environmental conditions
-Wave induced and vortex induced motionss (VIM) and related problems
-Solving fluid-structure interaction phenomena such as vortex induced viberation (VIV) and galloping

Computational fluid dynamics (CFD) is a powerful offshore design tool capable of accurate predicting complex flow phenomena. A key advantage is its ability to model the complex and arbitrary geometries that are typical of real-world equipment and environment.

Today, K-EPSILON's services help its customers with an accurate prediction of some of the most difficult offshore engineering problems, such as vortex induced vibration (VIV) issues, turret sloshing, vessel to vessel docking configurations, evaluation of current coefficents, platform seakeeping issues...

K-EPSILON is also able to provide Fluid-Structure Interaction (FSI) to model risers, flow lines, mooring system...

Simulation provides engineers with the ability to accurately determine the performance of design concepts, reducing the need for tank test and the building of prototypes. This makes it possible to evaluate many more designs in a shorter time, resulting in a substantial improvement in performance.
