1.1.2 When
appropriate, the load and design criteria detailed in this Part are
to be supplemented by direct calculation methods incorporating model
test results and numerical analysis for novel designs. Full scale
measurements may be required where considered necessary by Clasifications
Register (hereinafter referred to as 'LR').
1.1.3 Alternative
methods of establishing the load and design criteria will be specially
considered, provided that they are based on model tests, full scale
measurements or generally accepted theories. In such cases, full details
of the methods used are to be provided when plans are submitted for
approval.
