Project Number 608
Date of Summary October 4, 2007
Subject Methods to Reduce Lateral Noise Propagation from Seismic Exploration Vessels
Performing Activity Stress Engineering Services Inc.
Principal Investigator Dr. Ray R. Ayers, P.E.
Contracting Agency Minerals Management Service
Estimated Completion December 31, 2008
Description The technical effort will focus on discovering and validating by proof-of-concept testing a method or methods and equipment for affecting lateral noise reduction in the marine environment due to seismic operations. There are six tasks in this project:
  1. Perform a brief literature investigation) of technologies for marine acoustic wave propagation and methods of noise reduction.
     
  2. Develop or assemble a previously developed analytical model of the physics of marine acoustic wave production and propagation. This method will be essential in performing analyses of the candidate concepts for noise reduction.
     
  3. Use Invention MachineTM, the Scientific Method (analysis, synthesis, and hypothesis) and other inventive methods including “old fashioned discovery to identify candidate methods and equipment to reduce lateral noise for further evaluation. We have unique skills and experience in this task.
     
  4. Use engineering analysis and engineering judgment to rank order the potential performance and potential reliability of the candidate lateral noise abatement techniques. Task 2 above will provide the analysis methods for estimating performance, and simple Failure Modes and Effects Analysis (FMEA) methods can be performed to rank the relative reliability of candidate concepts.
     
  5. Propose simple proof-of-concept testing methods to determine the best candidate method and equipment in terms of performance and reliability. This might involve borrowing a production air gun to be fired in a water pit at a remote location. If proof of concept testing validates at least qualitatively a concept, further testing of a more rigorous nature would need to be performed to determine quantitative proof.
     
  6. Perform proof-of-concept tests - if funds exist - after the above work.
Progress This project has just been initiated.
