Apr 18, 2022 · Pipeline companies must determine possible routes for the new pipelines; acquire the right-of-way (ROW) to build, operate and maintain the pipelines; engineer the actual system designs; and construct the pipelines. Each of these steps are subject to rigorous regulatory reviews and approvals.

The construction of pipelines is a multi-step process. Many months prior to the actual pipeline construction phase, planning and surveys are conducted. Pipeline Construction steps can broadly be classified into the following three categories: 1. Pipeline Pre-Construction Activities 2. Pipeline Construction activities and 3. Pipeline Post-Constructi...
Pipeline pre-construction activities shall include the following: 1. Reconnaissance Survey 2. Detailed Engineering Survey 3. Permits and Clearance 4. Cadastral Survey 5. Acquisition of Right of Way(ROW) 6. Acquisition of Land forRepeater Stations and Block Valves 7. Approval of QA/QC procedure
Type of Crossings:
1. Open cut :Roads, cart tracks, and minor watercourses. 2. Cased :Railways, National Highways, and State Highways 3. Submerged crossings :Major rivers 4. HDD crossings :Perennial rivers and canals
Objectives for Hydrotesting
1. To establish that the pipeline has the required strength for which it has been designed. 2. To demonstrate leak tightnessof the pipeline.
Parameters for choosing test sections
1. Availability of water 2. Suitable place for disposal 3. Ground profile 4. Logistics
Pipeline Hydro-Test procedure:
1. Air cleaning the pipeline to clear all debris and muck 2. Gauging 3. Water filling with corrosioninhibitor 4. Thermal stabilization 5. Pressurization 6. Evaluation and acceptance
Post-construction Activities of pipelines construction shall include the following: 1. Caliper survey 2. Line preservation 3. Cathodic Protection 4. Commissioning
After the mechanical completion of the pipeline, the line is commissioned after the completion of the following activities. 1. Commissioning and making ready for the pumping and delivery stations. 2. Obtaining various permits and clearances. 3. Arranging products. 4. Click here to know more about pipeline start-up and commissioning activities
This resource page provides an overview of a typical pipeline construction project. Pipelines vary in size, length, and location, however, and each one present different challenges and operations. Construction plans for current proposed pipelines can be found on the FERC docket for that specific project.
Proper pipeline engineering ensures safe, efficient, and reliable transportation, making it a crucial aspect of infrastructure development. This article provides an in-depth overview of pipeline engineering, covering design principles, construction methodologies, and ongoing maintenance practices.
According to research by Underground Infrastructure and sister magazine Pipeline & Gas Journal, 41,999 miles of pipeline were under construction globally as we entered 2024. Another 80,557 miles of pipeline are in the planning stages, reaching a combined total of 122,552 miles worldwide.
Miller Pipeline has been a leader in sustainably maintaining and building America’s infrastructure since 1953 and provides a comprehensive range of pipeline contracting and rehabilitation services for natural gas, liquids, water, and wastewater pipelines.
Mar 19, 2024 · PHMSA has increased its new pipeline construction inspections in response to new pipeline projects. To ensure enough inspections are being conducted, PHMSA uses Annual Reports (AR) from pipeline operators to approximate the miles of newly constructed pipelines built each year.
