BACK-UP RECOVERY SYSTEMS OF DEEP-SEA MOORINGS.

Abstract

Failures of deep-sea moorings set without back-up systems usually result in the loss of valuable equipment and it is seldom possible to ascertain the modes and the causes of the failures. With a recognition of the need for development of auxiliary systems which would permit the recovery of that part of the failed mooring left on station, a number of designs were built and tested at sea in 1966, 1967 and 1968. These designs can be grouped into three basic types: inert ground line; active ground line; and in-line floatation. The report describes these back-up systems and reviews their in-situ performance. All systems were used at Site D (39 degrees N, 70 degrees W) in a depth of approximately 2700 m. (Author)
