NOAA OTEC CWP (National Oceanic and Atmospheric Administration Ocean Thermal Energy Conversion Cold Water Pipe) At-Sea Test. Volume 2. Additional Plots of the Power Spectra for Selected Channels (Part 3)

摘要

The report is a preliminary analysis of the data collected during the Ocean Thermal Energy Conversion (OTEC) Cold Water Pipe At-Sea Test. The report includes the following items: (1) Sensor factors and offsets and the data processing algorithms used to convert the recorded sensor measurements from electrical units to engineering units. The mean, standard deviation, and root-mean-square (RMS) are tabulated for each channel converted. (2) Plots of the power spectra estimates obtained from a Fast Fourier Transform (FFT) analysis of selected channels. (3) Plots of selected sensor measurements as a function of time; and (4) Plots of bending strain along the pipe using statistics and values presented in the other volumes. The plots displaying bending strain along the abscissa axis and pipe depth along the ordinate axis. The mean, RMS, maximum, and minimum values at each depth are shown in each plot.
