The 1993 revision of one of the Industry recommended practices on cathodic protection design offers the, operator the opportunity to use his own experience and data to justify more or less conservative designs. Examples of the use of this option to achieve an economic South China Sea design are presented. The design approach on how to subdivide the object being cathodically protected can be applied in any operating area where there is good environmental data. An example of the cost savings achievable by using this approach is presented. The optimised design is 55% of the cost of the design following the 1993 code.
