Tri-Strakes® L is a high quality Vortex Induced Vibration (VIV) suppression system consisting of overlapping and interlocking moldings, with three-start helical strakes to provide an effective triangular or trapezoidal strake profile.

Tri-Strakes® L has a temperature resistant up to 70°C/158°F.  Each section of the system has been designed as a single, lightweight component, enabling quick and easy pre-install onshore or install offshore. The design permits the system to be stacked efficiently during shipping which also reduces space taken up on the vessel.

The innovative manufacturing process means that the Tri-Strakes® can be produced up to six times faster than systems manufactured using traditional techniques, ensuring shorter lead times. Tri-Strakes® L can also be supplied in a variety of colors to meet individual project requirements.

Available with anti-foul coating or paint designed to protect against marine growth build-up, particularly in shallow water environments.
