Abstract

A model of configuration is made according to design parameters of a large design and is studied in trials so that the measured values are documented. If measured values do not match characteristics or requirements of design process, the parameters of configuration varies. If the measured values match with the design process characteristics and requirements of united execution, the release for realization of large design of model is made. The measured values of model are approximated with the characteristics and requirements of united execution to enable realization of large design. A model of the configuration of vessel design is made, according to design parameters of a large design, in which the model is composed of a main element and several modules. The model is studied in trials, and the measured values are documented and stored. The measured values are compared with predetermined design process characteristics. The requirements of large execution occur, if the measured values of the configuration correspond to the predetermined design process characteristics and requirements of united execution. If the measured values do not match the characteristics or requirements of design process, the parameters of configuration varies. If the measured values match with the design process characteristics and requirements of united execution, the release for realization of large design of model is made. The measured values of the model are approximated with the characteristics and requirements of united execution to enable realization of large design. An independent claim is included for a model for scaling of a large-scale design of a vessel.
