If you design a pipeline based on an obsolete or incomplete version and a failure occurs, your employer, client, or regulator will ask: “Was the design in accordance with the current API RP 1111?” Saying “I used a free download from an unknown source” is not an acceptable defense. Engineering judgments must be based on verifiable, traceable, current standards. As of 2025, a PDF of API RP

API RP 1111 is a recommended practice specifically for offshore pipelines. Unlike traditional allowable stress design (ASD), LSD checks performance under extreme, rare events—such as a 100-year storm, vessel impact, or seismic activity—where permanent deformation is allowed as long as failure (leak or rupture) does not occur. | | ASME B31
