Abstract: Rigid riser adapter operable to be at least partially installed into a lower riser balcony. The rigid riser adapter includes a receptacle support structure. Additionally, the rigid riser adapter also includes an adapter tube extending from the receptacle support structure substantially along a vertical direction, the adapter tube operable to be inserted through a lower riser balcony. The rigid riser adapter can also include a rigid riser receptacle coupled to the receptacle support structure, wherein the rigid riser receptacle is angled between six degrees and twenty degrees in relation to the vertical direction.

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.

Abstract: The invention relates to floating platform mooring and involves an improved platform mounted tendon tension monitoring system with porch mounted variable reluctance measurement technology sensors configured. The variable reluctance measurement technology sensors of this system are optimized for porch mounting. The porch mounted tendon tension monitoring system can also be configured such that the porch-mounted optimized variable reluctance measurement technology sensors are replaceable. Sensors may be replaced to extend the desired useful lifetime of a tendon tension monitoring system or in the event that a sensor happens to malfunction. A plurality of variable reluctance measurement technology sensors can be configured in sensor packs at the corners or at other locations where tendon tension monitoring can be useful for a floating platform.
