Design, Inspection and Repair of Oil and Gas Pipelines

Dear Colleagues,

Oil and gas pipelines are used for a number of purposes in the extraction of onshore and offshore hydrocarbon resources, and include single-pipe, pipe-in-pipe, and bundled systems.

The design process for each pipeline is generally the same and includes design engineering, load conditions, and stress analysis, developing strategies for minimizing costs, and providing operation and maintenance support to save on costs and ensure quality and safety.

Pipeline inspection is a part of pipeline integrity management, keeping the pipeline in good conditions. Safety regulations require the operator to ensure that a pipeline is maintained in an efficient state and working order, as well as in good repair.

Internal and external pipeline inspections are normally carried out through nondestructive testing techniques and equipment, such as magnetic flux leakage technology in axial and circumferential conditions, ultrasound technologies, eddy-current technologies, and others.

Damage to a pipeline can be repaired in different ways, depending on its type and extent. Onshore and underwater pipeline repair technologies are continuously developing to keep up with needs.

This Special Issue on the “Design, Inspection and Repair of Oil and Gas Pipelines” will include novel research advances using either modeling or simulation as an important component of oil and gas pipeline analysis and present the development of new and better design strategies for oil and gas pipelines, pipeline inspection technologies, and repair models. To maximize impact, contributing authors will be invited to deposit their process models in the open access repository for the process systems engineering community (PSEcommunity.org) and/or provide them as Supplementary Materials. These may include contributions such as process simulation or model files, computer and optimization codes, spreadsheets, and other relevant digital objects used for modeling and simulation purposes with either commercial or open source software.

The topics may include but are not limited to the following:

• General design process and approach for onshore and offshore pipelines;
• Internal and external nondestructive testing techniques and technologies;
• Development of models or simulations of pipeline leak detection systems;
• Simulation techniques, software, algorithms, or other tools for modeling and simulation;
• Design, inspection, repair, operation, and scheduling of maintenance strategies, diagnostics, prognostics, lifecycle analyses, or other pipeline integrity management and safety issues.

Thank you and I hope that you will consider participating in this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
