FEATURE: PORT EXPANSIONS KEEPING MANUFACTURERS BUSY

Buhler AG installed a Portalink 800/80RK ship unloader near Hayel Saeed
Anam and Co.'s flour milling facility at the Port of Aden in Yemen. The

missioned two NIV 300 pneumatic ship unloaders with a total
unloading capacity of 600 tonnes per hour. Mounted on rails
and on rubber wheels, the unloaders can unload ships up to
40,000 deadweight tonnes (DWT).
Once unloaded, the cereals are moved by a conveyor system
into the storage unit or directly to the 12 weighing or bagging
stations for direct loading onto trucks. The terminal's entire
conveyor system includes about 950 meters of belt conveyors,
most of which are rated at 600-tph capacity.
The reclaiming of the stored products is carried out by several
pay loaders on rubber wheels. A hopper at ground level handles
grains onto an inclined belt conveyor toward the conveyor system to the bagging stations. The 12 packing lines (six for grain,
six for fertilizers) each have a capacity of 1,200 50-kilogram
(kg) bags and allow for truck loading at a rate of 360 tph.
The lines are situated five meters above ground level so the
trucks can be lining up on one side before entering under the
corresponding bagging station, while on the other side they
can be loaded with bags that fall down from their platform
thanks to an inclined sliding ramp.
A control room with a synoptic panel as well as state-of-theart hardware and software allows for complete supervision of
all unloading, conveying, storage, weighing, bagging and dispatching of products, de Visscher said.
Sensors for monitoring conditions such as temperature, speed
and overload are connected to the central control desk where
the operation supervisors can monitor the whole operation and
record all the data necessary to continuously improve its efficiency as well as optimize the maintenance of all equipment.
MECHANICAL UNLOADER INSTALLED
Another ship unloading project in the Gulf of Aden was recently completed by Buhler for Hayel Saeed Anam and Co.'s
(HSA) flour milling facility at the Port of Aden in Yemen.
Buhler installed its Portalink 800/80RK ship unloader at
70

the HSA facility at the end of 2006, enabling HSA to unload
wheat or maize at a nominal rate of 800 tph from vessels up to
70,000 DWT on one side of the quay and 30,000 DWT on the
other side. The product is transferred by a gravity chute to a
belt conveyor installed below the quay.
At the end of the quay, the grain is transferred from the belt
conveyor to a bucket elevator, then onto other belt conveyors
feeding the rows of grain storage silos. Alternatively, the grain
can be loaded directly onto trucks via two loading spouts.
The decision to install the Portalink, which can unload grain
in a range of 400 to 1,500 tph from vessels up to 120,000 DWT,
was made by HSA in 2004, as it needed to take in more wheat
to meet its growing milling capacity, which had risen to 3,750
tonnes per day (five milling lines at 750 tonnes per day each).
The HSA milling facility in Aden, which is also equipped
by Buhler, imports all of its wheat from a number of countries such as France, Argentina, Russia and India, according
to Kousay Nadeem of HSA. The flour produced at the Aden
mill is then sold in Yemen, where HSA has a market share of
more than 60%.
HSA, a Yemen-based company that is active all over the
world in a wide variety of sectors, including agriculture, also
operates a flour mill with two 750-tonne-per-day milling lines
in Hodeida Port in Yemen.
RUSSIAN FACILITY ADDS UNLOADERS
Sodrugestvo, a Russian-based feed manufacturer, awarded a
contract to Melle, Germany-based Neuero to install two of its
Multiport ship unloaders at the company's soybean processing
terminal located on the Port of Kaliningrad on the Baltic Sea.
The Multiport unloaders, which have a rated unloading capacity of 600 tph, move soybeans from panamax-sized vessels
at the recently constructed Sodrugestvo facility, which is the
largest soybean processing plant in Russia.
Neuero also installed a Flexiport ship unloader, a pneumatic unloader that handles non-free flowing materials, to

MacGREGOR's Siwertell 790-D mechanical screw-type ship unloader, which
has an unloading capacity of 1,800 tph, was installed in 2006 at the Seaforth grain terminal at the Port of Liverpool in the U.K. Photo courtesy of
