Deepwater offshore structures are now quite common, however a deep water development project still requires significant capital investment on the part of the operator. Corrosion failure is not acceptable. This paper presents a common sense approach to cathodic protection design on deep-water projects. Some practical tips for avoiding pitfalls are presented as well as the role of ROV’S in maintenance and monitoring of these structures.
