This Handbook covers a large number of Pipeline Engineering topics, ranging from the initial stages of designing, constructing, operating and managing the integrity of a pipeline to several of their fluid transportation applications such as oil, gas, derivatives, slurry, hydrogen and CO2. Traditional onshore and offshore pipelines are covered, as well as chapters on present and future interaction with modern society. This Handbook serves as a first reference resource for new readers entering the field, but also as a complement to those who are aware of the general principles encompassing areas of pipeline engineering. This Handbook has been developed in close cooperation with ABCM, the Brazilian Society of Mechanical Sciences and Engineering.
