Dredging is needed where the seabed needs to be lowered or silt deposited in the sea bed is to be removed to achieve the water depth required for safe movement of marine vessels.
Dredging of soft deposits is undertaken with a dredging pump (electric or hydraulic driven) while in hard strata it may be necessary to first break up the formation using underwater hydraulic impact hammers or by chiseling. Ammico owns various types of electric and hydraulic dredging pumps as well as state of the art hydraulic impact hammers specially tailored for underwater operations.
Ammico has undertaken dreading both for lowering of sea bed adjacent to berthing structures as well as for removal of sediments under dry docks.
Projects involving Dredging Works include:
