Abstract: An analytical model of expansion movements at the ends of pipelines is developed. A comparison with measurements on two North Sea pipelines shows that the analysis is consistent with observed ...

Abstract: The stress-strain relations for materials and the load-deflection relations for structural elements play corresponding roles in the analysis of three-dimensional continua and of structures, respectively. ...

Abstract: A serious incident occurred during construction of a 36-inch pipeline in Colombia. A 500 m length of pipe on a hillside slipped on its supports, buckled, and slid down the hill, causing ...

Abstract: The stresses set up in a pipe being laid from a lay-barge over a stinger are determined by the configuration the pipe takes up. The equations governing this configuration are derived, and ...

Abstract: Based on previously available results and the recent research within the Liquefaction around Marine Structures program this paper formulates practical guidelines for design of pipeline on-bottom stability on noncohesive ...

Abstract: The conventional approach to pipeline stability design is reviewed and compared with experiments. A failure mechanism of pipelines on liquefied seabeds is analyzed. An analytical model to predict the pipelines sinking depth ...

Abstract: Understanding of the physical backgrounds is essential for good engineering practice with respect to liquefaction of sandy soils around and beneath marine structures. Several types of liquefaction can be distinguished. The ...
