Numerical investigation of the head and unsteady flow characteristics of a dredge pump loading high-concentration sands

The head of a dredge pump is an important performance parameter and a strongly fluctuating head may affect the operating stability of the pump unit. The IADC Young Author’s Award paper analyses unsteady characteristics of pump performance to improve control of the dredge pump.

Are the days of the double-walled pump housing numbered?

For several decades, the preferred solution for isolating dredging pumps within a vessel has been double-walled pump housing. To bypass this housing type’s intrinsic problems, Damen formulated an alternative.
