Patent CA-2330770-A1 (CA)
Title: Automatic loop segment failure isolation
Inventor: BALDWIN DAVID
IPC: H04J3/14
Filed: 1999-04-29
Abstract: A hub port (300) in a hub of a loop network which automatically bypasses a node port (314) which is generating a particular loop failure initialization sequence. The hub port contains a detection circuit which enables the hub port to detect loop failure initialization data received from its attached node port. Upon detecting such data from an attached node port, the hub port (300) replaces such data with buffer data to be passed to the next hub port. Upon detecting the completion of a loop failure initialization sequence from an attached node port, the hub port enters a bypass node. The hub port no longer passes on output from its attached node port and instead forwards along the internal hub link data received from the previous hub port in the hub loop.  The bypass is maintained until the hub port receives a primitive sequence indicating the recovery of the attached node port. The hub port periodically sends at least one recovery sequence to the node port. When the hub port receives the same recovery sequence back from the node port, the hub port ends the bypass and reinserts the node port back into the hub loop.

Filed: 1999-08-20
Abstract: A multi-purpose drilling rig has a movable pipe support cradle (60) which moves horizontally to transfer drill pipe from a storage area to the well being drilled, and vice versa. The cradle travels along a roof platform supported by load-bearing hydraulic lifting rams (40). Raising or lowering the lifting rams raises or lowers the roof platform, along with the drill pipe suspended from the cradle. Structural towers (30) stabilize the lifting rams against buckling and lateral loads. Supplementary lifting capacity is provided by cradle-mounted roof rams (62) having pistons which may extend downward from the cradle, with the drill pipe suspended from a yoke interconnecting the roof ram pistons. For offshore drilling, a control system senses fluctuations in rig elevation due to wave action, and automatically adjusts extends or retracts the rams as required to maintain constant laod on the drill bit. Also disclosed is a method of drilling which utilizes vertical and lateral movement of the cradle and top drive.
