Abstract:

A test program has been initiated that is aimed at reducing the maintenance costs associated with the recoating of deteriorated pontoon camel floats. Three 2-coat protective coating systems have been applied to pontoons on three test floats, and a material and labor cost analysis has been made on coating pontoons with each of these systems. A separate phase of the investigation is aimed at corrosion mitigation by cathodic protection. One of the test floats is currently being protected with zinc anodes, another with aluminum anodes, and the third float is serving as an unprotected control. After six months service to the fleet, the test pontoon camel floats were in good condition. No coating deterioration was noted, and the cathodic protection systems were providing electrical potentials that insure complete protection from corrosion to any exposed steel.
