Section 3 Model experiments

3.1.1 Model experiments and theoretical calculations may be required to be carried out for new design concepts and the results are to be provided when plans are submitted for approval.

3.1.2 Where model testing is undertaken, the following details are to be submitted:

1. A summary of the model construction and its instrumentation, including calibration of instruments.

2. A summary of the testing arrangements and procedures.

3. A summary of the tank facilities and test equipment.

4. Details of the wave generation, response measurements, definitions and notations.

5. Details of data recording, reduction and data analysis procedures.

6. Details of calibration procedures with theoretical computations.

7. Tabulated and plotted output.

3.2.1 Where model testing is undertaken, the minimum test matrix shown in Table 1.3.1 Minimum test matrix is required to be carried out:

3.2.2 In addition to those quantities which are normally measured in a model experiment, the following data are to be obtained where practicable:

1. Vertical accelerations at the LCG, bow and stern.

2. Acceleration loads due to heave and pitch.

3. Vertical bending moment.

4. Bow impact pressures at full forward speed.

5. Oblique sea loads inducing dynamic torque on the cross structure for multi-hull craft.

6. Splitting loads due to beam seas and roll motion for multi-hull craft.

7. Impact pressures in tunnel side and top for multi-hull craft.

3.2.3 The basis on which the parameters are chosen for investigation is to be submitted for approval.

3.2.4 Results from open water model experiments and full scale measurements may be accepted and full details are to be submitted for appraisal.
