Abstract
In this paper, we studied the current state of the design, manufacture and installation of marine pipelines, and considered the problem of manufacturability improvement marine systems pipelines at the stage of designing, providing the possibility of manufacturing the pipes without taking actual sizes and its solution within the framework of the research of the interrelation of configuration and compensation possibilities of the pipeline routes. The problem of compensatory possibilities of straight pipes on pipeline routes with a camber or with two and more cambers was examined. It was established that at simultaneous rotation of two different pipes with parallel ends, the end point moves along the surface (if the axes of these pipes are not parallel); at rotation of three or more pipes with three non-coplanar axes (i.e. not lying in the same plane) the compensation range is a three-dimensional body. The method of calculating the possible compensation area was improved in order to reduce the amount of computation. As part of the hypothesis about the relationship of the configuration and compensatory capabilities of the design pipeline routing, the idea of using straight pipes to move the pipeline route in order to compensate for errors in the manufacture of pipes and the installation of rigidly fixed connections of equipment, saturation products, etc., was presented, which ensured the collection of the route pipes.
