Scotland’s Ace Aquatec and marine ecosystem restoration specialist Ocean Health are partnering to develop FaunaGuard, an acoustic technology that can create temporary exclusion zones around offshore sites.

According to a news release, FaunaGuard uses academically validated sound patterns with award-winning transducer technology to create temporary exclusion zones around project sites at sea. This ethical acoustic system is an important tool for safeguarding oceanic wildlife from the risks associated with offshore construction works. Both Ace Aquatec and Ocean Health are working to make FaunaGuard globally available as the go-to mitigation solution for the offshore renewables sector.

Andrew Gillespie, marine protection products business manager at Ace Aquatec, said: “We are seeing a marked increase in demand from environmental surveyors, contractors and developers, who are specifying the need for more ethical solutions for safeguarding marine mammals from harm during construction projects. Our partnership with Ocean Health is accelerating change in the offshore sector to adopt a more species-specific approach to protection, rather than an outdated one-size-fits-all tactic.”

FaunaGuard has been developed over a decade and has been deployed in many pioneering offshore construction campaigns, in order to protect marine life from serious physiological harm. Ongoing research, development and testing has given rise to a unique species-specific modular system, which unlike older generation acoustic devices:

  • Targets exact hearing ranges of fish, seals, porpoises and turtles
  • Emits scientifically validated low-volume acoustics that do not cause hearing loss or deafness
  • Uses a series of complex tones to avoid habituation
  • Ensures the least physiological impact possible during subsea operations
  • Is fully compliant with the high standards set by the Joint Nature Conservation Committee (JNCC) in the UK and the Federal Maritime & Hydrographic Agency (BSH) in Germany.

FaunaGuard devices are typically deployed from a vessel to ensure animals are kept at a safe distance during other marine activities, such as pile driving, safe detonation of unexploded subsea ordnance, spawning protection and removing oil spillages. Experts hail FaunaGuard technology as playing a vital part in protecting marine life offshore.

Both companies say that their partnership will allow them to further develop the technology to include new species-specific sounds.

René Kersten, programme manager at Ocean Health, added: “The state-of-the-art technology used in FaunaGuard matches perfectly with our ambition to innovate the domain of ocean health. This partnership allows us to forge ahead with the development of new modules for additional species, so we are at the forefront of marine wildlife protection.”

FaunaGuard devices are due to be installed for Ocean Health next in the Baltic Sea from March 2023 onwards, with ongoing support from Ace Aquatec on monitoring marine life, having been recently deployed on CrossWind Hollandse Kust Noord project in the North Sea.
