The move from fossil fuels to renewable energy has many countries around the world pivoting to make the energy transition. With that pivot and the flow of investment in clean energy research and development, technology developers are looking at untapped hydrokinetic resources such as wave, current, tidal and riverine energy that hold the greatest potential to generate green energy.
The construction and operation of offshore wind farms carries regulatory requirements for acoustic monitoring of both noise emissions from the activity and marine mammals’ vocalizations. The latter reveal the presence of animals that could be at risk from noise exposure or collision with service ships.
Despite the global pandemic, wave and tidal energy projects have moved forward at pace, reaching significant funding, testing and deployment milestones over the last year.
One such example is Acteon’s patented Rocksteady connection system, an auto-latching subsea structural connector that enables wave energy operators to streamline installation processes and minimize costs.
In 2016, RS Aqua launched the multichannel Orca passive acoustic recorder, and the single channel Porpoise followed in 2018. Both recorders are very broadband, sampling at up to 384 kHz, and carry up to 4 TB of internal memory. They have proved successful in multiple sectors with almost 100 Orcas and 200 Porpoises being sold, with a high proportion into defence applications.
Huntington Ingalls Industries’ Technical Solutions division has been awarded a five-year contract with a total value of $273 million to support the U.S. Navy’s carrier engineering maintenance assist team, surface engineering maintenance assist team for west coast surface ships, and other maintenance and material readiness programs.
