4 Phased development method
4.1 General rules
This chapter describes the phased development method for devices carried out through pilot testing. The main objective of each stage is the stage threshold pre-defined
Tasks. The scaled-down wave conditions in the wave pool (tank) should cover the actual sea conditions in the proposed sea area, including its wave spectrum characteristics. Figure 1 shows the overall process from demonstration to operation, maintenance and optimization of the device. Before moving on to the next stage, each stage should be based on a reasonable choice of scale for a specific objective. This chapter defines the scope and stage thresholds from the demonstration stage to the engineering development stage to guide the development of the device from technology readiness level 1 to level 6. The real sea state test phase to operation, maintenance and optimization phase is mainly for real scale (or near real scale) device testing, which is out of the scope of this document.
5 Similar guidelines
5.1.1 General rules
For model tests, the following similarity criteria should be followed for scale determination.
Geometric similarity of the device and its mooring system;a
Structural (Corsi) similarity of the device and its mooring system.
The hydrodynamics of the device and its mooring system (Flaudströhal and Reynolds) are similar; g
d the energy conversion of the device is similar.
Since the above similarity criteria cannot be satisfied simultaneously, it is appropriate to conduct model tests of the device based on the Froude and Strauhar similarity criteria, while the mooring system should be based on the structural similarity criteria. If other similarity criteria are used, the Froude and Strauhar similarity criteria should be satisfied first. Similarity criterion inconsistencies when the model is expanded and released shall be documented. In addition to the (wave energy test-specific) energy conversion chain criterion, guidelines for other criteria are detailed in Appendix C.
6 Report Presentation
6.1 Test Objectives and Conditions
The factors considered in the test plan should all be documented in the report, including the design statement, test objectives, equipment selection, plan outline, and physical model characteristics. Special attention should be paid to the fact that similar criteria cannot be met simultaneously, so the report should give the impact of the problem in the expansion of the model to the real scale. If the test equipment does not fully satisfy the desired real-scale conditions, it is also appropriate to mark this in the report.
The test arrangement should record the form of the floating device in the pool (tank) in still water, the location of all sensors, and the location of the mooring points. In addition, should be recorded in the dry and wet environment device, sensors and mooring system of all calibration work.
7 test environment characteristics
7.1 General rules
The test environment conditions can provide an input background for data interpolation and should be carefully documented
8 Data acquisition
8.1 Signal Conditioning
Electronic sensors should try to record the original signal, in order to avoid signal distortion, in the acquisition stage should not be a large number of filtering or smoothing process.
9 Power performance
9.1 Test objectives
The power performance test is an important parameter for the evaluation of the power generation performance of the device. In the demonstration stage, the power generation capacity of the device is mainly characterized by the capture length (amplitude response operator) curve formed by the regular wave test. In the program phase, the power matrix can be obtained from the irregular wave test, and if sufficient data are available, the annual power generation capacity can be estimated. In the engineering development stage, the real sea state power matrix can be constructed using a scaled-down power conversion chain rather than a specific mechanism type.
Power performance tests should provide enough data to define the error limits for each set of parameters, see Appendix E for details of the methodology.
10 kinematic and kinetic characteristics in the operational environment
11 Kinematic and kinetic characteristics in the survival environment
11.1 Test objectives
Extreme sea conditions (testing under survival conditions should rely on the statistical description of the main performance indicators The magnitude of the extreme conditions depends on the response of the device to the environmental forces (motion and load). The test should provide statistical information about the structural and mooring forces on the response of the device to different man-ported wave conditions. If special survival strategies are considered, e.g., active adjustment of the device response to environmental forces, the strategy itself should also be tested.
