Since the first edition of this Handbook was published, in 2015, a great many developments with global implications have taken place that will profoundly influence the future, especially with respect to energy development and use. The present is a time of transition—in energy, technology, and economics. Digitalization and decarbonization will require massive effort and investment over the coming decade to respond to global needs resulting from demographics and climate change.¹

Consistent with global developments, the scope of this book, for the second edition, has been expanded to include digitalization, cybersecurity, carbon dioxide pipelines, and hydrogen pipelines, as well as many new technologies that offer opportunities for pipeline companies to consider during the energy transition and for enhancing pipeline reliability, energy deliverability, and environmental protection.

The Handbook consists of 73 chapters divided into 10 parts across two volumes:

This is a technical book where all those who are involved with pipelines—engineers, scientists, consultants, technologists, managers, executives—as well as students, environmentalists, journalists, etc. will find information for explaining and supporting:

• The safe, continued operation of existing pipeline networks, and
  
• As part of the green transition, the repurposing of existing pipeline networks and development of future pipeline networks for transporting carbon dioxide and hydrogen.

Topics that are new to the second edition include:

• The Digital Future of Pipeline Integrity Management (Chapter 1)
  
• Cybersecurity and Safety Implications of Pipelines (Chapter 2)
  
• Practical Applications of Machine Learning to Pipeline Integrity (Chapter 3)

As the editor of this Handbook, I would like to thank the authors of chapters for their dedication and commitment that they have shown in preparing their chapters, responding to reviewers’ comments, and completing their chapters in a timely way so that this second edition could become a reality. This includes the authors of new chapters and the many authors who revised and updated their chapters for the second edition. In all, 125 authors from 16 countries contributed the 73 chapters in this Handbook.

I am very grateful to the reviewers of chapters, all of whom carried out their work anonymously.

In addition, I greatly appreciate the continued encouragement and support of the entire Wiley organization, beginning with Michael Leventhal in the Hoboken headquarters and extending to other Wiley offices with their highly competent, efficient, and effective personnel.

Finally, I would like to thank my wife, Viviane, for her encouragement and support throughout this project.
