Buckle arrestors for deepwater pipelines

Two different buckle arrestor configurations were tested experimentally in order to evaluate the feasibility of using them for deepwater pipelines. Long steel alloy pipes with diameter-to-thickness ratios of 16 and 23 were provided with buckle arrestors and tested under quasi-static conditions in a hyperbaric chamber. Empirical formulae were obtained from the experimental results taking into account both pipe and buckle arrestor geometries as well as material properties.
