A potential profile of the modified mooring was made approximately 3 weeks after the mooring was laid, giving the data listed in Table 7. It can be seen from these data that all readings were well above the desired minimum level of -850 mv and most were above -1,000 mv. Two of the four anchors were also receiving cathodic protection despite the attempt to prolong anode life by avoiding this. Additional potential profiles were p

It can be seen from these data that all readings were well above the desired minimum level of -850 mv and most were above -1,000 mv. Two of the four anchors were also receiving cathodic protection despite the attempt to prolong anode life by avoiding this. Additional potential profiles were prepared 4, 10, and 13 months after installation of the modified mooring. These are shown in Tables 8, 9, and 10, respectively. From these tables it can be seen that the underwater portion of the buoy, the riser-chain, and all four ground legs were receiving full protection from corrosion. All potentials were well above the desired minimum level of -850 mv, and almost all were above -900 mv. In addition, two of the four anchors were receiving full protection much of the time, despite attempts to avoid it. 25.
