AIMS fixed-fin vortex strakes are designed for ease of installation and are custom manufactured to project specifications. The strakes can be installed via S-lay, J-Lay and Reel-Lay, as well as our patented ROV-friendly design. 

AIMS strakes are backed by full scale tank testing with Reynolds Numbers (Re) ranging from the low 1,000s to ~2,000,000. In fact, AIMS’ 3D matrices have been introduced into the SHEAR7 program for utilization by riser designers.

Our material of construction, molded polyethylene, allows good manufacturing tolerances and repeatability, low drag coefficients, and high efficiency in (vortex-induced vibration) VIV elimination. Other materials can be used upon request. Furthermore, AIMS can also coat the strakes to achieve Antifouling characteristics.

AIMS standard design employs a triple helix with a 15D fin period and a 0.25 D fin height. Other designs can be manufactured upon request. 

The VIV Suppression Efficiency of AIMS strakes is 93 percent or greater. Our average Drag Coefficient, cd, is 1.5.
