Osprey Fearless | tugster: a waterblog

So here was 1 and in it I said I would answer a question in a few days and now a few weeks have passed. The question pertained to the device mounted on the stern of vessel

Husky. Congrats to Seth Tane, who guessed correctly. Here’s what Xtian writes: “It’s a plough. In French we talk about “nivelage” [leveling], which means after dredging the bottom of the sea is like a field that has just passed a plow. This tool cuts the bump to fill the gap. It’s also used in the rivers where the “alluvium” or the mud stays in always same places because of the current and built like “bottom hill” there. And it happens also in some harbour (like ferries’ harbour) as because the ferries always doing the same maneuver and raise the mud that still lay at the same place.

With the plough used at the right time, ebb tide for example, the mud is raised and leaves the harbour with tidal current. In some places the plough is used to feed the hopper dredger – when the dredger is too large, the plough is used to remove a “bottom hill” when they are close to the bank to give the mud at the place where the hopper dredge is working. The plough is not only used with mud but also with sand or pebble. Google with words : Dredge – Plough.

About Husky, the day I took this picture she was working closely with the dredge Rijndelta at the entrance of Maasvlakte harbor. I add a picture of her below.”
