Full Option Damen CSD450 for Nigeria
At the end of December last a Damen type CSD450 cutter suction dredger named Ononaku, was prepared for transport to Nigeria for Fiddil Nigeria Ltd. The Ononaku is a standard dismountable dredger of well-proven design, enhanced by a number of options. Set to travel to Port Harcourt early this month, Ononaku will work in the Niger Delta on a project for the Shell Petroleum Development Company alongside its sister vessel, the Damen CSD500 Princess Ona.
The cutter suction dredger, type CSD450, is a standard dismountable dredger of well-proven design, enhanced by a number of options. The standard dredging depth was enlarged by 2 m, resulting in a max. dredging depth of 14 m. Furthermore anchor booms and winches were added. These anchor booms shift the dredgers anchors without the help of an auxiliary vessel. The efficiency is boosted also by the addition of a spud carriage pontoon. The pontoon is a simple addition to the standard dredger, but facilitates dredging using the 3.5 m cylinder stroke hence manoeuvring is minimized.
The dredger has been fitted out with an accommodation unit, on top of which the control cabin is placed for optimal view of the deck and the job site. The accommodation unit is equipped with a galley, a seating area, and a sanitary space. The unit includes fresh water and wastewater tanks, plus an air condition unit. Moreover, a mast with navigation lights is fitted, plus four floodlights and a searchlight. On the portside pontoon a jib crane was added to handle spares in and out of the store.
