Basic Principles and Simplified Analyses
Marine risers are unusual structures that defy standard engineering intuition, yet they are critical to the safety and structural integrity of offshore platforms. In this new edition, six additional chapters provide further arguments to support effective tension as well as original analysis of helical buckling.
Marine risers are unusualstructures that defy standard engineering intuition, yet they are critical tothe safety and structural integrity of offshore platforms. In this new edition,six additional chapters provide further arguments to support effective tensionas well as original analysis of helical buckling. An entire chapter is devotedto the Macondo accident of 2010, where it is known that helical buckling of thedrill pipe within the riser led to pipe deflection inside the blowout preventer(BOP), sufficient to prevent the latter from closing the well.

Features and benefits:

• Details on the Macondo incident and howthe behavior of the drill pipe within the marine riser affected this tragedy
• Analysis of helical buckling inside ariser associated with flexing pipe inside a seabed BOP
• Discussion of how and when planar bucklingtransforms into helical buckling
• Three new Excel files that allow readersto perform further calculations with their own data
