Maintenance Dredging
Every Port or Harbour designed with certain
designed navigable depth in it’s channel or water bodies for the safe entry and
exit of ships. This depth will decrease due to deposition of sediments
and other material by the influence of littoral drift, underwater
currents, wave & tidal actions etc., in a course of time which
varies from Port/Harbour to Port/Harbour and depends on rate of
siltation. To restore it’s depth, removing the accumulated material is
inevitable in most of the Ports & Harbours. The process of removing
the accumulated material is called “Maintenance Dredging”.
DCI is fully equipped to
cater to the maintenance dredging requirements of all major Ports in
India.
Capital
Dredging
The process of removing the “virgin” soil to create
the designed depth in the water bodies/adjacent to water bodies is
called “Capital Dredging”.
DCI is having
two Cutter Suction Dredgers to meet he capital dredging requirements in
the India/Abroad. A New Cutter Suction Dredger of 2000 Cu.M per hr
dredging capacity will join the DCI fleet during Oct-2004
Beach
Nourishment
The coastal line in the beach is subject to
deposition/erosion of sediments due to various reasons. However if the
rate of erosion is more than rate of deposition, it is necessity to
replace the quantity of erosion to maintain the coastal line intact. The
process of deposition of sediments in the coastal line from the
adjoining areas is called “Beach Noursihment”
DCI ‘s
Dredge-XII and Dredge-XIV are capable of shore pumping up to 2400m and
Dredge-XVI and Dredge-XVII are capable of shore pumping up to 2500m and
rain bowing facility.
Reclamation
The
process of raising the land level to create a artificial land either
just below or adjacent to water bodies is called “Reclamation”. The
fill material is generally used from the adjacent water bodies so as to
improve the depth in the water bodies as well as to use to same for
creation of land.
DCI’s
Cutter suction Dredgers, Dredge-XII, Dredge-XIV, Dredge-XVI and Dredge-XVII
are capable for
reclamation purposes.
