Which document serves as the basis for pipeline training according to COOQ and the API?

The document that serves as the basis for pipeline training according to the COOQ (Certification of Operator Qualification) and the API (American Petroleum Institute) is API Pub. 1161: Guidance Document for the Qualification of Liquid Pipeline Personnel. This document specifically addresses the training, qualification, and evaluation procedures for personnel involved in the operation and maintenance of liquid pipelines. It provides a framework that ensures personnel are equipped with the necessary competencies to effectively manage and oversee pipeline safety which is critical in the industry.

API Spec. 5L focuses on specifications for line pipe, primarily concerning the materials and manufacturing processes, rather than the training of personnel directly. API RP 1173 deals with pipeline safety management systems, which outlines organizational processes but does not serve as a primary training document. Similarly, API Std. 1104 pertains to the welding of pipelines and related facilities, emphasizing welding standards rather than broad training for pipeline personnel. Therefore, API Pub. 1161 is correctly identified as the foundational document for training, emphasizing its role in establishing qualifications for those involved in liquid pipeline operations.
