IPC: G06F9/54
Filed: 2019-11-29
Abstract: Data processing apparatuses, methods of data processing, complementary instructions and programs related to ring buffer administration are disclosed. An enqueuing operation performs an atomic compare-and-swap operation to store a first processed data item indication to an enqueuing-target slot in the ring buffer contingent on an in-order marker not being present there and, when successful, determines that a ready-to-dequeue condition is true for the first processed data item indication. A dequeuing operation, when the ready-to dequeue condition for a dequeuing-target slot is true, comprises writing a null data item to the dequeuing-target slot and, when dequeuing in-order, further comprises, dependent on whether a next contiguous slot has null content, determining a retirement condition and, when the retirement condition is true, performing a retirement process on the next contiguous slot comprising making the next contiguous slot available to a subsequent enqueuing operation. Further subsequent slots may also be retired. An atomic compare-and-swap operation finally stores the in-order marker to a reached slot contingent on content of the reached slot. An atomic sequence number compare-and-swap-max instruction is also proposed to support these operations.

Title: Method of monitoring the loading of a subsea production system
Inventor: Joakim Martens
IPC: E21B47/007
Filed: 2020-08-13
Abstract: A method of monitoring the condition of a connector between two bodies e.g. umbilicals, jumpers or subsea workover components 100. The method comprises installing the connector 18 to join adjacent bodies 130, 140, 150 and using a connector sensor output and a numerical model to determine a measured force of one or both bodies, the degree of relative body movement or the connector condition. The numerical model is obtained by applying a known magnitude test force to a test element secured to the connector or a test connector, recording the sensor output with the test force applied for a plurality of test forces and using the obtained data to create a numerical model relating the output from the sensor assembly to the force on the test element. The sensors may be strain gauges or pressure sensors which feed a subsea storage 34a. A statistical representation of the model derived from a multivariat analysis may be used in a subsea processor 36a to provide real time failure warning and a full version of the model at the subsea processor or at a topsides processor 36b may provide a long term detailed, e.g. fatigue, analysis.
