Riser

Last updated: December 31, 2018

What Does Riser Mean?

A riser is a segment of offshore pipelines that protrudes from the offshore platform into the ocean floor. Due to its seawater location, a riser is prone to significant levels of corrosion. Pitting and other corrosion types are rampant due to constant erosion and electrolytic charges due to salt content. These can be controlled via the use of cathodic protection.

A riser may also be known as a riser pipe.

Corrosionpedia Explains Riser

The degradation of risers are common due to hydrogen generation. It is important to ensure that risers are designed to withstand the nature of the environments in which they are installed. Risers are exposed to corrosion-prone environments internally and externally due to transport fluid flow and outer seawater flow. As a result, both sides of the riser are usually treated with different corrosion prevention techniques.
