Drill riser buoyancy design helps to expand drilling rig operating envelope in high-current conditions

By  Kelsey Ware, Trelleborg Offshore Deployment from 6 deepwater rigs demonstrates module’s ability to suppress vortex-induced vibration, improve rig performance in harsh environments The helically grooved buoyancy module technology can help to suppress vortex-induced vibration without increasing the effective diameter of the riser. Further, because the suppression mechanism was included into the body of the buoyancy […]
