Sandvorspülung/Sand Replenishment

The East Frisian Islands on the German North Sea coast are constantly eroding and moving, as they are basically sand deposits in the sea. Some of the islands are constantly moving towards the East, as sand is eroded on the west side and deposited on the east side due to storms and currents in the sea. To protect the coastline of the islands and also the people living there, some islands like Norderney use sand replenishment (Sandvorspülungen in German). This means, a special kind of ship (hopper dredger; Saugbaggerschiff or Hopperbagger) collects sand from a sand bank close to the beach and then pumps it through a pipeline on the beach.

This year a sand replenishment was done while we were there and as I’m always fascinated by things I haven’t seen before, of course I took pictures. If you want to know more about the whole process, wikipedia is your friend. 🙂

The pipeline is running along the beach and is moved on as the sand builds up. The ship connects to the pipeline and then pumps a mix of water and sand through the pipeline. It’s really quite impressive to see how this works. The ship is the Magni R from Denmark.
