Abstract
The invention involves utilizing variable reluctance measurement technology (“VRMT”) sensors to monitor forces and stresses on drilling risers and riser towers. The tension monitoring system described herein includes an optimized configuration of variable reluctance measurement technology sensors, wherein the sensors have increased wire turns around each end of their C-cores or alternatively are mounted on mechanical amplifiers or both. An array of optimized variable reluctance measurement technology sensors can be configured at multiple points on a riser system. The VRMT sensors may be integrally attached to the risers or flexible joints for the risers, or may be installed on existing riser or flexible joint systems.
