Abstract:
As interest grows in developing devices to harvest energy from ocean waves, tidal currents, and offshore wind, concerns over possible environmental effects from such devices also grow. One such concern is over the induced electric fields and the generated magnetic fields from generators and their associated submarine power cables in an ocean environment, including the possible effects on ocean wildlife. A method for analytically calculating magnetic and electric fields around undersea power cables based on the carried current was developed. Testing was performed to validate the analytical solution, and a field deployable magnetometer device was developed to measure magnetic fields in a marine environment.
