PERFORMANCE ANALYSIS OF WOODS HOLE TAUT MOORINGS

The Woods Hole Oceanographic Institution has been using deep-sea moored buoys for acquiring serial observations of ocean currents, temperature and other data for over twelve years. A brief description of the deep-sea mooring program is given. The mooring statistics and performance are described. Mooring failures of 1970 and 1971 have been categorized and statistics on the modes and causes of failures are presented. The reliabilities of different types of moorings are computed and compared. The role of radio telemetry for the real-time measurement of mooring line tension and its use in checking the mooring status are discussed. Examples of potential design data like tension and currents recorded by moorings that failed are provided. Finally, recommendations for research and development needed to improve mooring reliability are given. (Author)
