Temperature, initial slope imperfections, and downward restraints on a pipeline all affect its propensity for upheaval buckling. A restrained pipeline is subject to compressive loads as the ...

In early 2000, BP Exploration (Alaska) Inc. successfully enlarged Seal Island, a man-made gravel island offshore Alaskan Beaufort Sea, and installed the Northstar pipeline system, the first trenched ...

Long subsea pipelines, never laid in a perfectly straight line to begin with, tend to move over time. It’s a problem exacerbated by the high-temperature, high-pressure conditions in which pipelines ...

An engineer has designed a model to guide better design of thin-walled structures, like planes, cars and submersibles, to avoid catastrophe like sudden collapse due to buckling. A University of ...
