Future Applications – “AutoAMP”

Future Applications – Wave Energy

• Integration with Wave Energy Converter

• Real-time monitoring without power cable

Conclusions• Monitoring is needed to assess environmental risk of

marine energy converters• The AMP has been developed to meet this need• Future development will adapt the AMP to meet test site

requirements
