Abstract
A system, in certain embodiments, includes a spider configured to support multiple mineral extraction riser segments. The system also includes a gimbal disposed below the spider and configured to support the spider during operation. The system further includes one or more arcuate radio frequency identification (RFID) antennas disposed within the gimbal and/or the spider. The one or more arcuate RFID antennas are configured to communicate with one or more RFID tags coupled to each riser segment.
Claims15
A system comprising:
- a spider configured to support a plurality of mineral extraction riser segments;
- a gimbal disposed below the spider and configured to support the spider during operation;
- and
- one or more arcuate radio frequency identification (RFID) antennas disposed within the gimbal, the spider, or a combination thereof, wherein the one or more RFID antennas are configured to energize and communicate with one or more RFID tags coupled to each riser segment.
A system comprising:
- a spider configured to support a mineral extraction riser segment;
- a gimbal disposed below the spider and configured to support the spider during operation;
- a first antenna disposed on the gimbal at a first antenna position, wherein the first antenna is configured to receive identification information from a first transmitter mounted on a flange of the riser segment at a first transmitter position;
- and
- a second antenna disposed on the gimbal at a second antenna position approximately 180 degrees offset from the first antenna position, wherein the second antenna is configured to receive identification information from a second transmitter mounted on the flange of the riser segment at a second transmitter position approximately 180 degrees offset from the first transmitter position.
A system, comprising:
- a set of first and second wireless receivers disposed on opposite sides of an annular bore, wherein the first and second wireless receivers comprise opposing first and second read ranges less than an area of the annular bore;
- and
- a set of first and second wireless transmitters disposed on opposite sides of an annular structure disposed in the annular bore, wherein the first and second wireless transmitters remain within at least one of the first and second read ranges as the annular structure moves within the annular bore.
