Drill Riser Buoyancy Module Helically Grooved integrates Vortex Induced Vibration (VIV) suppression and drag reduction with drill riser buoyancy, increasing rig efficiency without compromising on safety or structural integrity.
Drill Riser Buoyancy Module Helically Grooved buoyancy design dimensions are optimised to ensure uncompromised uplift, while effectively eliminating riser motions and higher levels of drag in harsh offshore environments, when compared to traditional riser buoyancy. Drill Riser Buoyancy Module Helically Grooved is a multi-functional solution integrating VIV suppression and reduced drag technology, essentially eliminating the requirement of ancillary suppression equipment, and alleviating complicated and time intensive riser running and retrieval procedures.
Drill Riser Buoyancy Module Helically Grooved reduces riser motion by limiting the number and magnitude of strain cycles transferred to subsea equipment, decreasing fatigue loading, and extending service life. The minimal removal of material associated with the Drill Riser Buoyancy Module Helically Grooved design corresponds to only a 2-3% buoyancy loss, which is easily recovered.
