Abstract
During operation of the offshore pipelines vibration processes occur as a result of pump plant running, shut-off valves activation, emergency shutdowns and external effects. If there is a crane unit (underwater block valve station) on the offshore pipeline, special consideration should be given to the seismic resistance of this section of the pipeline. Studies have shown a high level of stresses in the pipe wall of in the pipeline connecting section and the crane assembly. It has been concluded that it is necessary to introduce damping devices for the crane units of the offshore pipeline to ensure its seismic stability.
Keywords: offshore pipeline, offshore pipeline block valve stations, seismic resistance analysis.
