Magni DRBM HG (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.

Magni DRBM HG buoyancy design dimensions are optimized to ensure uncompromised uplift, while effectively eliminating riser motions and higher levels of drag in harsh offshore environments, when compared to traditional riser buoyancy.  Magni DRBM HG 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.

Magni DRBM HG 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 Magni DRMB HG design corresponds to only a 2-3% buoyancy loss, which is easily recovered.
