Rapid population growth and technological advances with more demand for energy and its dwindling resources on the land, have caused mankind to look for new sources of energy in the oceans and seas.

In this regard, the offshore industry has been developed to explore and extract oil and gas resources and transfer them to the land.

Submarine pipelines are one of the most important parts of the offshore industry, whose design and construction play a special role in development of this industry.

In the upcoming booklet, the topics raised in the basic engineering studies of submarine pipelines, including process design, criteria for pipeline thickness calculation, criteria for route design, basics of cathodic protection system design, and finally, corrosion mechanisms and coating systems are discussed.
