This standard presents acknowledged practices for the control of external corrosion on offshore steel pipelines. Historical Document 1988
The control of external corrosion on offshore pipelines is important to the oil and gas industry because of the need to protect capital investments in manpower and materials, conserve natural resources of oil and gas, and protect the offshore ecology. This NACE standard has been prepared to present procedures and practices for achieving effective control of external corrosion on offshore steel pipelines. No other standards that are based on the experience and expertise of the pipeline industry relating to this topic are available at this time. This NACE standard is based on the procedures and practices set forth in NACE Standard RP0169-83, "Control of External Corrosion on Underground or Submerged Metallic Piping Systems."'1l However, because of some different procedures and practices and because offshore pipelines cannot always be inspected as readily as onshore pipelines, this offshore pipeline standard is different from RP0169-83 in several areas.
This standard includes guidelines on external corrosion control design for offshore steel pipelines, including the use of protective coatings and criteria for cathodic protection, the design and installation of cathodic protection systems, control of interference currents, operation and maintenance recommendations, and corrosion control records.

This study is focused on description, discussion and analysis of the different technologies available against external corrosion in offshore export pipelines and its suitability for the Venezuelan pipeline offshore projects. Several anti-corrosive protective coatings and concrete weight coating were evaluated.
HISTORICAL DOCUMENT. Test method specifies procedures to evaluate cathodic disbondment resistance of the steel structure coating systems under cathodic protection, such as buried or submerged pipeline and tank linings.
