Lankhorst VIV suppression systems
Cylindrical structures, such as free-standing riser pipes or flowlines in free spans, interact with a uniform fluid such as seawater and shed Karman vortex sheets. If the vortex shedding frequency is close to the cylinder’s natural frequency, the structure will start to oscillate, or vibrate.
The VIV oscillations of submerged pipes are known to increase drag and may lead to structural fatigue. One proven means of suppressing this vibration is the use of strakes, which modify the flow along the pipe, tripping the production of Karman vortices so that they act less coherently.
Lankhorst has designed solutions to effectively reduce vortex induced vibrations well over 90% and minimize fatigue and drag on subsea and offshore structures.
