Abstract:
A riser data logging system can be installed on the riser top to provide real time information of the riser, instead of or in addition to relying on sensors installed on a tensioner. The riser recoil detection system can thus be made independent of any motion of the vessel. This logging system can feedback the riser top acceleration, velocity, position, and the wire-line tensions into a controller. By comparing the acceleration difference between the riser top and the vessel body, the controller can provide more reliable and faster detection of events occurring on a vessel, potentially detecting the condition within one second. If the acceleration exceeds a certain limit, the electrical tensioners are able to reduce the wire-line tension nearly instantaneously, providing a much more effective anti-recoil control that conventional hydro-pneumatic tensioners.

Claim (Index 12):
The apparatus of  claim 11 , in which the controller is further configured to reduce the tension applied to the first and the second wires if the difference between the acceleration of the top of the drilling riser and the acceleration of the vessel exceeds a threshold.
