OTEC (Ocean Thermal Energy Conversion) Current Study.
Abstract
A fundamental element of all currently proposed Ocean Thermal Energy Conversion (OTEC) systems is a long, large diameter cold water pipe (CWP) which will serve as a conduit for cold water from the ocean depths to a heat exchanger at or near the surface. There will be various envirommental forces acting upon the CWP. Those of primary concern are on the wave action on the CWP suspension system at the surface, and the ocean current hydrodynamic forces on the pipe itself throughout its length. The latter is the subject of this report. A string of current meters with the necessary buoy and anchor accessories was designed. It comprised eight Aanderaa current meters, 100 feet apart, suspended from a 40 inch diameter subsurface buoy and anchored to the bottom as shown. Contents: Installation Preparation; Installation of the Current Meter String; Current Meter Characteristics and Operation; Recovery and Inspection of Current Meters; Processed Results of Measured Data; Pressure and Temperature Data; Current Velocity and Direction; Vector Diagrams of Currents at Various Depths; Spectrum Analysis of Current Velocities; Interpretation of Plotted and Tabulated Data.
