A CONTRIBUTION TO THE DETERMINATION OF DIMENSIONAL ALLOWANCES IN HULL ERECTION BY APPLYING THE DIMENSIONAL-CHAIN THEORY

Deviations (within the tolerances allowed) in the dimensions of individual components lead to "production uncertainties" that can cause difficulties in the erection of an assembly, but if the expected deviations from nominal dimensions are known they can be taken into account. The individual uncertainties will together result in an overall uncertainty whose value can be predicted by various methods. The East German standard TGL 19115 describes three dimensional-chain calculation methods for such predictions: the maximum/minimum method, the probability-theory method, and the compensation method. The Authors explain how these three methods can be applied in the production of a flat hull-section, and illustrate their use with the worked example of such a section being welded together from a number of plates and other members. It is mentioned that this study is a contribution to the reduction of rectification and fit-up work in hull erection, and that some further investigation is necessary. Order from BSRA as No. 49,807.
