This project was to test a prototype wave energy device by towing it behind a boat. A major challenge was that a longer rope was required for safe towing than could be used for the electrical connection during the test. This meant the electrical connection had to be made safely at sea. I worked with Oceaneering to design an electrical panel and accompanying operation procedure to allow safe operation of the breaker on the device, with no risk of energising the connectors from either the wave device or the boat. The final system included a circuit breaker on the device, combined with dry battery cells and large breaker status lights that could be seen from the vessel. This project also involved interfacing with other companies working on the generator control and instrumentation, as well as factory acceptance tests at both the panel builder and at the facilities of Supply Designs in Rosyth, who produced the power electronics.
