DEVELOPMENT OF THEORETICAL BASE FOR RESEARCH INTO COMPENSATION OPPORTUNITIES OF DEVIATIONS IN THE SHIP PIPING SYSTEMS
To improve the technology of ship piping systems at the design stage is an actual problem. The authors have analyzed technological features of manufacturing ship piping systems and have also considered the current state of design, manufacture and installation of ship pipeline issues. The review of research in the field of compensation of deviations of pipeline routes is presented. The problem of improving technology of ship piping systems at the design stage is considered providing the possibility of manufacturing pipes without removing dimensions in place. The authors have proposed the solution for the issue within studies of relationship of configuration and compensatory possibilities of pipeline routes. The authors are suggesting the idea of using straight pipes for moving the pipeline route to compensate for errors in the manufacture of pipes and the installation of tightly fixed connections of equipment, saturation products, etc., which ensures collecting the route without changing configuration of ready-made pipes. The proposed development allows to control and reduce at the design stage possible deviations that occur in the manufacture of pipes, to minimize the gaps assigned to the tracing of pipelines. The authors have reached the following research outcomes: mathematical description of the compensation capabilities of pipeline routes by using straight pipes; 3D models of compensation area are constructed; the necessary condition for full compensation of deviations, without the use of measure pipes lies in the presence in the track of two pairs of straight pipes with non-planar directions. The theoretical basis for designing an automated program has been developed that will allow determining the areas of compensatory opportunities for pipeline routes. The authors proposed the idea of replacing bottom pipes for the pipes supplied, which helps to reduce the time for constructing ships.
