There are over 20,000 miles (32,180 km) of pipeline currently in service in the Gulf of Mexico. Approximately 2/3 are transmission pipelines. Of the transmission pipelines, over 96% have a single diameter, and 70% operate between 1,000-2,000 psig (6,895- 13,790 kPa). The damage reports were reviewed, and approximately 39% were attributed to corrosion. Internal corrosion damage was reported approximately four times as frequently as external corrosion. The next most common cause for pipeline was associated with natural events, such as subsea land slides and storms/hurricanes. Surveys were conducted with the offshore operators to identify their approaches to integrity management. It was found that they have adopted risk-based approaches to integrity management, and rely heavily upon various monitoring techniques, coupled with the implementation of preventative measures, such as corrosion inhibition, etc.

A new field gradient (FG) measurement tool has been developed for cathodic protection (CP) inspection of subsea facilities. The paper presents a case where FG data and CP modelling have been used to optimize CP retrofit design, cutting costs by 50%.
