clapping for Lynetteholm stops

Work on dredging in the entrance to the harbour, for the construction of the man-made island of Lynetteholm, has been stopped because further reports are now required on the environmental impact of dredging polluted sludge from the site and taking it down the coast to the bay at Køge to dump.

There is growing criticism of the new island and it has become a contentious issue in both parliament and in the press because criticisms or, at the very least least concern, from the Swedish government about the construction work and the island itself was not revealed when a construction act for the work was debated and passed in the Danish parliament.

note:
When I wrote about Lynetteholm in the New Year, I had to confess then that I was not sure what the Danish term klapning meant or rather what it means specifically in this context when clearing the sea bed of sludge by dredging.

The word used in all newspaper articles was klapning but dictionaries and Google always gave me clapping as the English translation but neither word was used in general articles on dredging.

Finally I tracked down the answer.

When sludge is dredged up to clear a channel or, as here, to form a stable base for constructing a man-made island, the sand and mud can be loaded onto large open barges or ships and they sail down the coast where, over a designated site, they open large flaps on the underside of the hull to release the sludge. Those flaps can be opened and closed several times to dislodge everything .... hence clapping. Obvious now I know.

at the centre of the view is Trekroner Fortet - the Three Crowns Fortress - built in the 1780s to guard the entrance to the harbour

the new island will fill the whole horizon beyond the fort with just a narrow channel for boats to enter and leave the inner harbour

by 2070, when building work on the island is set to be completed, this view will be filled by the skyline of new housing for 35,000 people

 

work to start on dredging for the construction of Lynetteholm

At the end of 2021, the Danish Parliament passed a Construction Act for Lynetteholm and work on the new, man-made island across the entrance to the harbour will start later this month with extensive dredging that will remove sludge across the sea bed to form a stable base for the next stage when landfill will be brought in to create the island.

That sediment - estimated to be around 2.5 million tonnes across the sea bed - is described as "slightly polluted" so, presumably, that means that there is contamination from the harbour, contamination from shipping entering and leaving the harbour and pollution from the old ship yards on Refshaleøen.

‘Sludge’ will be taken south by barge to be dumped in the bay off the town of Køge. The Danish word used in the local press for this is 'klapning' or clapping but I'm not sure if that is the process or the term for the sludge. A recent article talked about the 'clapping area'.
