Italian built dredger fleet grows in Nigeria
The newbuild cutter suction dredger is seen on site in Nigeria.
Dredger builder Italdraghe SpA has just supplied the latest of a long line of dredgers to Nigeria. The new SGT 600D CSD is already at work on sand winning projects in the Lagoon of Lagos.
For the owner of the new purpose designed SGT 600D, this is just one more in a long line of Italdraghe dredgers to be added to his growing fleet of Italian vessels.
The new addition, a 50m long and 8.20m wide cutter suction dredger complete with spud carriage and anchor booms, will be used together with an Italdraghe SGT 600 booster station for commercial sand stock piling as well as future land reclamation and channelization projects.
The fully dismountable dredger has a suction diameter of 700mm and can work down to a maximum depth of 16m. It is equipped with a very generously sized raised control cabin offering elevated all round vision. The cabin has glass floor panels which allow the operator visual control of on deck activities below.
The dredger features an Italdraghe SGT 600 onboard horizontal axis dredging pump with a power of 2,035 hp and two Cummins engines. The main engine is a Cummins QSK60, V-16 cylinder, turbocharged 4 stroke and the auxiliary is a Cummins KTA19 M3, in-line 6 cylinder turbocharged 4 stroke.
The pump has an intake diameter of 650mm and an output diameter of 600mm.
The booster station is driven by a V-12 cylinder 3516 Caterpillar engine with a maximum continuous power of CV 1,735 at 1,600 rpm. The booster station pump, with a five blade cast steel impeller, is manufactured from Cr-Hard cast iron which, with a hardness of 550/650 Brinnel, is exceptionally resistant to abrasion.
