Pipeline Integrity Management Under Geohazard Conditions (PIMG)
Chapter 10 A COMPREHENSIVE STUDY ON THE EFFECT OF SOIL MOVEMENT DUE TO MANMADE OPERATIONS ON SUBSEA PIPELINES
Download citation file:
Geohazards for pipelines are typically generated by natural events such as mudslides or earthquakes. Additionally, deformation or energy released due to manmade geohazards near pipelines can inflict significant damage. These types of events may affect a limited pipeline length but can cause substantial local deformation potentially resulting in leakage. Spudding near fixed jackets is a typical example of such risks. Jack-up rigs are often utilized nearby shallow water fixed platforms and pipelines for well intervention operations. The effects of spudcan penetration/extraction operations on nearby platform piles have been studied extensively and generic guidelines are adopted by many regulatory bodies...
