Behavior of Subsea Pipelines Expansion under High Pressure and Temperature Design

Abstract

In offshore operation, Crude oil is transported by means of
pipeline system from oil well to platform at High Pressure and
High Temperature. The pipeline will experience expansion and
multi stresses due to internal pressure and operating temperature
that the material properties of pipe tend to deformation which
affect to the durability of pipeline. This phenomenon should be
considered in the design process of pipeline and to estimate the
expansion is under limit of pipeline strength otherwise the
pipeline will be failure cause of catastrophic.
