Analysis of the Condition of the SNAP 7-E Acoustic Beacon Installation after 64 Months at 2,650 Fathoms.
Abstract
An isotopic generator powered acoustic beacon installation was recovered after 64 months of exposure to the seawater and bottom sediments at 2,650 fathoms of depth in the Atlantic Ocean south of Bermuda. An analysis of the deterioration of the components of the installation showed that the basic steel support structure and the isotopic generator housing suffered only minimal attack. The lifetimes of these elements are projected to exceed ten years at this site. Stainless steel components of the installation were severely corroded and the use of stainless steel is not recommended. The bottom environment in this location was found to be atypical and similar installations at other sites would have significantly shorter lifetimes. (Author)
