Damen dredge valves for deep sea mining

Damen dredge valves and pumps, available for purchase through Damen’s sales operations in the Americas, have been recently delivered for the purpose of remote operated deep sea mining vehicles – a departure from their usual use for hopper dredgers or cutter suction dredgers.

These deep sea mining vehicles, also called Seafloor Production Tools (SPTs), have been manufactured by Soil Machine Dynamics (SMD), which has designed and built three SPTs, each for a specific task.

The first machine, the auxiliary cutter, Damen delivered a number of dredge valves and an electrically driven dredge pump. Damen delivered another dredge valve and pump set for the second machine, a bulk cutter. For the third collecting machine, Damen delivered a customised cutter unit, a number of dredge valves and three electrically-driven dredge pumps.
