Section 9 Testing and trials

Parent topic: Chapter 6 Hybrid Electrical Power Systems

9.1 Testing

9.1.1 Testing in accordance with Vol 2, Pt 9, Ch 12 Testing and Trials is to be carried out as applicable.

9.1.2 Where required by the Rules and Regulations for the Classification of Naval Ships, January 2023, items are to be constructed under survey.

9.1.3 Materials are to be approved, manufactured and tested in accordance with a standard acceptable to LR.

9.1.4 The fault ride-through capability of the system is to be demonstrated during practical tests on the system.

9.1.5 Quality of power supply testing of the system and the components is to be carried out to prove the equipment is capable of operating under the variations specified by the hybrid electrical power system integrator and accepted by LR for all normal and reasonably foreseeable abnormal operating conditions.

9.1.6 Where considered necessary by LR, additional testing may be required.

9.2 Trials

9.2.1 Trials in accordance with Vol 2, Pt 9, Ch 12 Testing and Trials are to be carried out as applicable.

9.2.2 Satisfactory operation and load testing of the hybrid electrical power system in harbour and during sea trials, are to be witnessed by LR.

9.2.3 Measurements are to be taken as part of the trials to verify that the installation will provide a quality of power supply in accordance with the values declared by the hybrid electrical power system integrator as described in Vol 3, Pt 1, Ch 6, 6.2 Power quality and stability.

9.2.4 For Hybrid Power (+) notation additional trials are to be carried out to:

  1. Verify that the system delivers the determined levels of performance as described in Vol 3, Pt 1, Ch 6, 4.2 System performance targets;
  2. Verify that the system fulfils the redundancy principles defined by the hybrid electrical power system integrator as described in Vol 3, Pt 1, Ch 6, 4.3 Dependability principles;
  3. Verify the correct operation of the additional energy management functionality described in Vol 3, Pt 1, Ch 6, 4.2 System performance targets;
  4. Verify that the system performs in accordance with its simulation(s) as described in Vol 3, Pt 1, Ch 6, 7.6 Energy flows and Vol 3, Pt 1, Ch 6, 7.7 Power system analysis; and
  5. Verify the findings of the FMEA analysis detailed in Vol 3, Pt 1, Ch 6, 7.10 System Failure Modes and Effects Analysis (FMEA) and the response of the system to simulated failures.
