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:
- Perform a brief literature investigation) of technologies for marine
acoustic wave propagation and methods of noise reduction.
- 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.
- 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.
- 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.
- 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.
- Perform proof-of-concept tests - if funds exist - after the above
work.
