The Biggest Cement Carrier Conversion
in the World
26,367 DWT Turkish flag bulk carrier M/V "NAZLI-K"
belonging to Genel Denizcilik Nakliyat A.Þ. of
Turkey was converted into a pneumatic self-unloading
cement carrier in 1996 with a total unloading
capacity of 500 tons per hour.
A
Multinational Cooperation
Gemak
Shipyard of Turkey has completed the whole conversion.
The cement handling equipment was supplied by H.W.
Carlsen of Sweden and the design was provided by
Shiptech Pte. Ltd. of Singapore.
Discharging
Capacity of 500 Tons Per Hour
There
are two cement discharging pipes each side with
250 tons per hour discharging capacity each and
one discharging pipe each side with a capacity of
500 tons per hour. There is also a gravity-discharging
boom with a capacity of 500 tons per hour installed
on the part side.
In order to provide the necessary compressed
air and the vacuum for the operation following
equipment was installed in the new constructed
machinery room placed on top of No.3 cargo hold;
Two (2) diesel-compressors
, each 650 kW
Two (2) vacuum
pumps , each 230 kW
Two (2) blower
, each 86 kW
One (I) blower
, each 26 kW
Two (2) aux. compressors
, each 17 kW
The engine room incorporated also the control panel
for the cement unloading system and the main switchboard
providing the power distribution to the electric
motor driven equipment. There are four deck filters
consuming each 22 kW and a vertical screw conveyor
for the gravity unloading, consuming 126 kW, installed
on main deck portside.
Special
Fabric for Cement Fluidisation
Some
3,000 m2 of special fabric has been bolted onto
the new inclined bottom of cargo holds in order
to fluidise the cement by compressed air provided
from new compressors.
All
Completed in 3 Months
Vessel
stayed at the yard for 3 months in which all prefabricated
sections totalling of 1,200 tons of steel were installed,
together with 25,000 m of cabling and 10,000 m of
piping by using 3-D modelling in design and fabrication
stages.
