@ all Thanks for all "piling in" :) with your suggestions and help

This would refer specifically to offshore wind turbines - the curtain of bubbles is a good clue: they act as an effective acoustic barrier to water-borne sound, though low frequency sound transmitted through the sea bed is another issue. There is quite lot of information on the web about offshore piling and the installation of wind turbines.

But... I doubt the noise is due to 'driving' the feet into the ground, because the solutions proposed to limit the noise are soft starts and some form of noise mitigation mechanisms. That would suggest that the noise is present all the time, that it resonates through the 'feet' of the turbine. I would suggest that in using the term 'plantage', the author is simply nominalising 'planter', so something along the lines of 'placement'. However, if that is so, it's kind of redundant in English.

To: Asker The context (especially the "battage") suggests "pile driving", but the common French term for "pile" is pieu. I cannot find much support for "pieds"--> "piles".
