| description | The paper considers the problem of improving the manufacturability of ship system pipelines at the stage of designing. Some solutions of manufacturing and installation of ship system pipelines without taking dimensions at the place have been presented. During the experimental calculation the purpose and objectives of the experiment have been defined, the plan of experiment has been designed and the necessary initial data have been prepared. The experimental calculation of the compensating capabilities of ship system pipelines in four stages has been made. They are: the choice of routes between two rigidly fixed connections according to the drawing and preparation of data; the determination of the computational domain of compensatory capabilities of traces on the basis of theoretical assumptions within the hypothesis of using pairs of parallel sections of traces to compensate for total deviations; the determination of the fit area with an assigned allowance; the adjustment of drawings by changing the dimensions of the fit areas with allowances. The experimental calculations have confirmed the theoretical predictions of compensatory capabilities of pipelines at the design stage and conceptual basis for compensating for total deviations by moving traces. The algorithm for compensation of pipelines' deviations using the mutually parallel sections with joints of pipes and additional allowances has been developed. Based on the research results prerequisites have been created for developing a methodology for improving the manufacturability of pipelines at the design stage. With regard to more pipelines the opportunity to replace a downhole pipe to an adjustable pipe has been offered, bending of which will be carried out according to project dimensions without clarification in place, contributing to a reduction in the construction of facilities, complex technological systems saturated with pipelines. |
