MandR:
With 40 year of dutch dredging experience and 100% local content in Nigeria we combined forces to design and build a powerful 10" stationary dredger capable of dredging upto 30m deep. By combining a 10” underwater pump with a 10” booster pump we are able to dredge much deeper (up to 30m) and pump much further than most similar size dredgers. Our 6” jet-pump discharges water under high pressure (12 bar, 450m3/hr) to break-up sands enabling high density mixtures. This is how we did it:
