    摘要： A seismic streamer system and associated methods for estimating the shape of a laterally steered seismic streamer. The streamer is divided into a series of contiguous streamer segments by lateral-steering devices. Heading sensors positioned in forward and aft portions of each segment produce heading readings. Each segment is modeled as having a linear shape in the forward portion and a curved shape in the aft portion. The shape of the segment is estimated according to the model from the heading readings on the segment.

    摘要： A two-tier communication system for a seismic streamer. The communication system operates over an unshielded twisted-pair communication line extending the length of the streamer. Repeater units having a repeater function and a device controller function divide the twisted pair into line segments. Coils on each segment couple signals inductively to collocated external devices in a low-speed 2400 baud FSK data link between the devices and an associated device controller. A Gaussian 8-level FSK high-speed 60 kbit/s data link is established along all the segments with the repeaters re-transmitting boosted signals along the entire length of the communication line. The coils are transparent at the high-speed data rate. Time division multiple access (TDMA) or frequency division multiple access (FDMA) is used to accommodate the two links on the single twisted pair.

    摘要： An underwater seismic system for reducing noise due to ghost reflections or motion through the water from seismic signals. The system includes two motion sensors. One sensor has a first response and is sensitive to platform-motion-induced noise as well as to acoustic waves. The other sensor has a different construction that isolates it from the acoustic waves so that its response is mainly to motion noise. The outputs of the two sensor responses are combined to remove the effects of motion noise. When further combined with a hydrophone signal, noise due to ghost reflections is reduced.

    摘要： A measuring device which maximizes the surface area of a blade transducer, which is swingably coupled to a probe member, and utilizes the force of the medium, such as a slurry, flowing in an in-service pipeline to swingably align the blade transducer in a desired measuring position. The swingable coupling of the blade transducer to the probe member provides for the retraction from and insertion into the medium flowing in the in-service pipeline for repairs, replacement, or sanitization or other maintenance or servicing of such blade transducer, without shutting down the pipeline and related processes, without compromising the integrity of or disturbing the connection (sealed, flanged, welded or otherwise) between the measuring device and the transducer port in such pipeline and significantly minimizing the environmental exposure of the medium. Moreover, the retractability feature of the swingable blade transducer enables other components of the measuring device to be replaced, repaired and sanitized or otherwise maintained or serviced, as desired.

    摘要： A system and a method for rejecting noise in an underwater sensor cable, such as a towed streamer or an ocean-bottom cable. An adaptive hydrodynamic model of the cable produces an estimated sensor signal from a raw sensor signal from a particle-motion sensor, such as an accelerometer. The estimated sensor signal represents an estimate of the response of the underwater cable to cable motion absent seismic events. A noise-reduced response to particle motion alone is produced by subtracting the estimated sensor signal from the raw sensor signal to reject cable motion and other noise effects in the raw sensor signal. A seismic event detector uses a hydrophone signal from an acceleration-canceling hydrophone to disable the adapting of the hydrodynamic model during seismic events. The hydrophone signal is combined with the response to particle motion by PZ summation to produce a deghosted seismic response signal.
