Near full-scale tests on instruments to determine parameters of floating craftsвЂ™ static trim and draft
When manufacturing and setting-up different marine instruments there area frequent cases when setting-up and informative tests of such instruments are not possible without ship (with tests facilities). Most commonly to optimize and check algorithms and software intended for processing data from these instruments, mathematical models of relevant objects and phenomena are used. However, sometimes phenomena affecting to a large extent accuracy of the instruments and data processing results with mentioned algorithms and software are so much complicated that their adequate mathematical models are not developed yet and full-scale tests are difficult. In such cases it seems reasonable to combine tests of floating craft model and instruments to be fitted onboard. Such tests may be called near fullscale ones. That was the scheme to carry out individual tests of instruments’ analogues meant for determination of static trim and draft parameters of floating craft in emergency in heavy seas. The Article generalizes some experience gained with respect to such tests
