摘要：
The present invention is a method for deploying a drilling riser VIV suppression system in which a first retaining ring is installed on a syntactic foam buoyancy module encircling the drilling riser with a spring loaded connection. The spring loaded connection is capable of adjusting the diameter of the retaining ring automatically to compensate for compression of the syntactic foam under the influence of water pressure. VIV suppression provisions is then installed about the drilling riser using the first retaining ring as a load shoulder.
