Engineers Develop Quieter Massive Sea Hammer to Protect Fish Ears

By Gary Cutlack on at

Apparently marine noise pollution is a thing nowadays, because us humans need to always be smashing something into somewhere it don't belong, even at the bottom of the sea. This disturbs sea life, causing seahorses to bolt and fish to swim away to somewhere nicer, like the Faroe Islands. Hence a new generation of more sensitive massive undersea hammer is required.

Massive undersea hammers are used when driving in foundations for wind turbines, seeing as another thing us lot on land can't do is go more than six minutes without boiling a kettle or charging something up. They call this sensitive new millennial hammer the Blue Hammer, or the Fistuca BLUE 25M hammer to use its formal name, and it's been tested by a consortium of electricity generators, including our own SSE, that are installing a bank of 84 wind power turbines in the Moray Firth.

The ambition is to provide a "...more energetic, but quieter blow" to the sea bed (lucky sea bed, etc), which, as well as reducing noise, lessens the impact on whatever lump of stuff is being hammered in — increasing longevity of components and allowing more fabrication to be done offsite somewhere flat and dry. So it'll be cheaper. A bit. And only for them, not us. [BBC]
