Pipeline Miscellaneous

Introduction

The Pipeline Toolbox is home to many tools and calculators. The PLTB User’s Guide presents information, guidelines and procedures for use during operations and integrity tasks for field or office applications.

This recommended practice applies to onshore steel pipelines. Moving in-service pipelines can be a safe, cost effective means of relocating a pipeline without loss of service. The recommendations presented in this RP should be applicable to any lowering or other movement of existing pipelines that is undertaken either to accommodate new roads, railroads, foreign utilities, ditches, or creeks or to accommodate any condition for which moving the pipeline is the chosen alternative.

The practice is to address the criteria, methods, values, and recommendations that should be considered in the design and execution of practical and safe pipeline-movement operations. However, it is impossible to foresee all possible pipeline-movement situations or circumstances. This recommended practice is to be used as a guide for moving pipelines while they remain in service.

Module/Application

API 1117 – Movement of In-Service Pipeline
- Movement of in-service Pipelines is calculated to conform elastically to a given trench profile. Longitudinal Stress due to bending/elongation and elastic curvature must be considered.
