VIV Suppression Strakes

VIV Suppression Strakes
Our VIV suppression strakes combine the impact and abrasion protection benefits of Uraduct with an effective helical strake profile

To reduce the effects of VIV, we have developed a range of cost effective VIV suppression systems to suit various installation and pipeline scenarios including pipeline free spans, top tensioned risers (TTRs) and tendons.



Our VIV suppression strakes combine the impact and abrasion protection benefits of Uraduct with an effective helical strake profile. The system consists of overlapping and interlocking easy to handle mouldings typically 1.5 to 2.0m long and incorporates 3 start helical strakes with either a triangular or trapezoidal profile. The mouldings are manufactured as a single split line moulding in a range of marine grade polyurethane and polyethylene elastomers including options for stinger installation and marine growth inhibition.
 
The mouldings are secured in place using the same corrosion resistant banding material and technique as used with the Uraduct product. the bands are pre cut to the required length and come complete with pre-formed seals. Manual or semi-automatic tensioning banding tools are available.
 
The entire system can be easily pre installed onshore, installed offshore simultaneously during the pipe laying operation, or alternatively, should the need arise, we have also developed an ROV retrofit system.
