In the article, the authors examine the problem of enhancing the technological features of ship's pipeline systems at the designing stage. Moreover, it introduces the solutions for questions of ship pipeline's manufacturing and assembling without measuring the actual size of the ship. The possibility of using the rotating method for paralleling pipe sections simultaneously with technical operation of removing the technical allowances of the pipelines is taken into consideration to fully compensate the total deviations of pipelines routes, which was arisen not only in process of pipes' manufacturing but also in hull, mechanisms, and equipment's assembling. An algorithm for determining the compensation level of the pipeline route is established. Based on the results of the researching process, the method to determine the compensation possibilities of pipeline routes and values of technical allowances is established, which was appointed on fitting pipes for expansion in the compensation field in possible directions. The author presents the method of pipeline displacement by using the rotation method to rotate the parallel sections of the pipelines for compensating total deviations, and the technology of assembling the pipeline systems from prepared pipes, which was produced by designing information without measuring the actual size of the ship.
