Abstract:

An investigation was conducted on corroded ANSQA-10 VDS towcables to obtain information for determining the adequacy of the Naval Applied Science Laboratory developed monthly towcable inspection procedures replacement criteria, which are currently being used in the Fleet. The results obtained indicate that corrosion is a maximum at the towpoint and descreases with distance from the towpoint, and that for cables with up to two years of service the deleterious effects of corrosion become negligible at a distance of ten to fifteen feet from the towpoint. The results also indicate that cable corrosion is, in general, related to total time in service regardless of the amount of towing time. These results are not significantly different from those obtained during the initial phase of this work and which were used as the basis for developing the monthly towcable inspection procedures and replacement criteria. Recommendations are made for continuing monthly inspections of ANSQA-10 VDS towcables in accordance with the procedures and criteria developed at NASL. Author
