Jokra had a various history: Cuttersuction dredger, (pipe)suction dredger, barge unloading dredger and at the end of lifetime used as "leverler" the bottom in the river Nieuwe Maas, Rotterdam. Leveling was executed with sand > 250mu , because a pit was too deep, and had a result of salt problem/income from the Noordzee.
