Abstract
In this paper, the solutions for problems related to increase in manufacturability of pipelines at a design stage were stated. The authors considered conditions and possibilities for compensating deviations of the pipeline route and adjacent structures during pipe installation. The task was set to produce a fitting pipe according to the design information without specifying dimensions and configuration in place on the ship. The fitting pipe was manufactured according to the design information with the assignment of technical allowances at the end sections in certain directions, if necessary. Moreover, the authors presented a method for compensating deviations in the routes of ship pipelines using rotations of pipe parallel section pairs, and developed the procedure for compensation and installation of pipelines from prefabricated pipes manufactured according to design information without specifying dimensions on the ship. Mathematical and graphic modeling of deviation compensation in pipelines during their installation was performed.
