1.1 This recommended practice provides guidelines for establishing minimum requirements for the control of corrosion on steel, fixed offshore platforms associated with petroleum production, and on the external portions of associated oil and gas handling equipment. For this document, corrosion on platforms is divided into three zones: the submerged, splash, and atmospheric zones. Each zone is examined.  1.2 This recommended practice does not designate guidelines for every specific situation because of the complexity of environmental conditions. In many instances, there may be several solutions to the problem and, where appropriate, meritorious alternative solutions have been included. 1.3 This recommended practice does not include guidelines for corrosion control of the internal portions of wells, piping, and associated equipment that may be installed on or attached to 1.4 This recommended practice includes corrosion control of the external surfaces of attached pipelines above the splash zone. Where ownership of the pipeline is different from that of the platform, the platform owner's responsibility for the pipeline usually ends at a  designated point or valve on the platform.  1.5 Alternative methods are acceptable to accomplish the objectives of this recommended practice; however, deviation should be made only if, in the opinion of a competent corrosion specialist, the objectives expressed in the recommended practice have been ahcieved.
