- W2025986515 abstract "Phillips Petroleum Co. presents the results of a parametric study analyzing a pipeline displaced from the seafloor to some pipeline-construction configuration. For a pipeline modeled as having constant rigidity, horizontal tension, and submerged weight per unit length, there is a maximum value that the maximum sag-bend moment attains as the distance from the pin-supported end of the pipe to the seafloor increases. The pipeline is modeled as a continuous beam having a constant submerged weight per unit length and a constant horizontal tension or force with one end supported vertically by the seafloor. The governing differential equations are solved in terms of dimensionless combinations of the three characteristic variables--the submerged weight per unit length, the flexural rigidity, and the constant horizontal tension. This allows any possible pipeline configuration meeting the stated constraints to be analyzed and the maximum sag-bend moment to be specified. This maximum sag-bend moment is changed by varying the seafloor vertical force until a further change in seafloor reaction does not give a pipeline configuration. The maximum attainable maximum sag-bend moment may be then computed and graphed as a function of the three characteristic pipeline values named above." @default.
