Installation of cathodic protection on the 3100-foot portion of the one 12-inch and six 8-inch crude oil pipelines under the Mississippi River which connect the Baton Rouge Refinery and the Anchorage Tank Farm was completed in May, 1951. A current density of 3.5 milliamperes per square foot was used as the minimum requirement for full protection of the 52,000 square feet of surface area of these pipelines. A 100 ampere, 30 volt rectifier and a groundbed were installed on each bank of the Mississippi River to supply the protective current to the pipelines from both sides of the river. The groundbeds were designed to utilize the mutual interference effect of the anodes to force the current to flow toward the middle of the river and to secure overlapping protection from the two units. Pipe-to-soil potential measurements on both banks of the river indicate that overlapping protection was achieved and that full protection to the pipelines has been accomplished.
