Kiel/Wilhelmshaven, 25th April, 2025 – HASYTEC Electronics AG is currently testing an adapted frequency range for its ultrasound antifouling technology that is outside the porpoise’s communication range.
In 2023, the innovative cleentech company from Kiel was commissioned by the Federal Ministry for Economic Affairs and Climate Protection to equip one of the two LNG terminal ships in Wilhelmshaven, the FSRU EXCELSIOR, with its environmentally friendly antifouling technology in order to avoid the chlorination that would otherwise be required. This saves around 32 tons of chlorine entering the Wadden Sea every year.
After the contract was awarded, concerns were raised about the harbor porpoise population, as HASYTEC’s ultrasound waves are partly within the animals’ communication range.
HASYTEC has dealt intensively with these concerns and has used the last six months to adapt the operational frequency range.
The aim of the test phase is to rule out any possible impairment of the porpoises in the Jade Bay caused by the ultrasound technology by ensuring that the HASYTEC frequencies are outside the communication range of the porpoises. The results of the test phase so far are very promising. However, the final test is still pending.
“We are convinced that this is exactly the right way to make innovation and environmental protection sustainable and fit for the future,” says Andreas Hoffmann, Chief Technology Officer at HASYTEC.
