Caisson dredging system

TMS of Werkendam has delivered an extremely innovative caisson dredging system to Volker Stevin.

Lowering a caisson into the soil to the required depth has been hard work under high pressure. The soil below had to be removed manually from the space below the caisson which is pressurized to prevent the caisson from lowering uncontrollably.

TMS has delevoped a dredging system that can be lowered through a purpose built manhole that can automatically dredge the soil below the caisson and thus lower the caisson to the required depth. Hycos has designed and delivered the hydraulic drive system as well as the control system to operate the system.
