标准范围

ISO 15589-2:2004规定了ISO 13623中定义的石油和天然气行业海上管道阴极保护系统的安装前调查、设计、材料、设备、制造、安装、调试、操作、检查和维护的要求，并给出了建议。ISO 15589-2:2004适用于海上服务中的碳钢和不锈钢管道。ISO 15589-2:2004适用于现有管道系统的改造、修改和维修。ISO 15589-2:2004适用于在水下条件下遇到的所有类型的海水和海床环境，以及平均水位以下的立管。请注意，有时存在阴极保护无效或仅部分有效的特殊情况。这种情况可能包括高温、涂层剥离、隔热涂层、屏蔽、细菌攻击和电解液中的异常污染物。

ISO 15589-2:2004 specifies requirements and gives recommendations for the pre-installation surveys, design, materials, equipment, fabrication, installation, commissioning, operation, inspection and maintenance of cathodic protection systems for offshore pipelines for the petroleum and natural gas industries as defined in ISO 13623.ISO 15589-2:2004 is applicable to carbon and stainless steel pipelines in offshore service.ISO 15589-2:2004 is applicable to retrofits, modifications and repairs made to existing pipeline systems.ISO 15589-2:2004 is applicable to all types of seawater and seabed environments encountered in submerged conditions and on risers up to mean water level.Note that special conditions sometimes exist where cathodic protection is ineffective or only partially effective. Such conditions can include elevated temperatures, disbonded coatings, thermal insulating coatings, shielding, bacterial attack, and unusual contaminants in the electrolyte.
