KEYWORDS: Offshore Pipeline, Installation, FEM Global and Local Analysis, Design Criteria, Failure Mode, Limit State. 1 INTRODUCTION Development plans are now considering gas pipeline projects in water depths up to 3000-3500 m. Hence, the offshore industry is called to solve...

... cases where pipelines are subjected to high internal pressure and high temperature i.e. exposed pipeline laid in a flat or uneven seabottom and buried pipes. The design criteria are based on the application of reliability methods to calibrate the partial safety factors involved. In this paper...

Design criteria for induction bends do not reflect the R & D efforts of the recent years and working stress...
