A Risk-Based Inspection Planning Method For Corroded Subsea Pipelines

Abstract

Risk assessment procedures for subsea projects are a key component of design and maintenance and inspection efforts, as resulting operating time may cause aging damages to adjacent subsea equipment. In particular, for subsea pipeline management work, corrosion of pipelines may impinge on a vast number of subsea pipeline system sandcan result in significant environmental and financial risks,unless the appropriate management methodologies are implemented. Hence, this paper presents risk based on probability of failure (PoF) and consequence of failure(CoF)estimation of a time-variant corrosion model and burst strength for the corroded oil pipelines.
