  • Method for suppressing noise from seismic signals by source position determination
    Patent number: 6751559
    Abstract: A method is disclosed for attenuating noise from marine seismic signals caused by a noise in the water. The method includes determining an arrival time of a noise event at each of a plurality of seismic sensors, estimating a position of the noise source from the arrival times, and attenuating the noise event from the signals detected by the seismic sensors.
    Type: Grant

    Date of Patent: June 15, 2004
    Assignee: PGS Exploration (UK) Limited

  • Method of reduction of noise from seismic data traces
    Patent number: 5818795
    Abstract: A method of suppression of burst coherent noise in seismic data is provided comprising (a) comparing a threshold amplitude characteristic acceptance value for a time window of a reference trace to an amplitude characteristic of a test trace of a set of traces within the window and; (b) applying a non-zero scalar to the test trace in the time window if an amplitude of the test trace within the time window is not within the threshold amplitude characteristic acceptance value.

  • Vessel loading method
    Patent number: 4483655
    Abstract: A large cargo vessel is loaded by moving a self-unloading barge alongside and fixing it relative to the vessel. A boom assembly of the barge is slewed into alignment with a hold of the vessel whereupon a shuttle conveyor is extended over the open hold. Bulk material is then unloaded from the barge to the vessel. The boom assembly can be incrementally slewed, luffed, extended and retracted to position cargo in the hold. And, the barge can be repositioned next to the ship without assistance of a tug.
