transloading terminal requirements.
“When a non-continuous system is employed at the loading
port’s transloading terminal, grab cranes are used to unload the
feeder vessels to the hoppers on deck, and also to transfer
materials to the hoppers from the terminal’s cargo holds if it has
any. The deck hoppers feed a deck conveyor system that
transfers the material to the shiploader and so on to the oceangoing
“The greatest benefits are delivered by a continuous system.
Not only does this arrangement have the potential to deliver
very high cargo transshipment rates, but it is also the most
environmentally friendly solution, because when the conveyor
system and the shiploader are totally enclosed, it results in much
reduced dust emissions”.
For a transloading terminal at a discharge port, Cargotec has
designed many different types of boom conveyors for unloading
cargo to a vessel or ashore. Furthermore, the shiploader could
be fitted on a moveable gantry, providing the facility to load a
Capesize vessel without any need to warp the vessel along the
Dust levels can be reduced during transloading by installing
water spray nozzles in the discharge chutes between conveyors
and in unloading points. Dust collectors are also used to
minimize dust leakage from the cover joints. These function by
applying suction to critical points in the conveyor system to
create a negative pressure. The dust-laden air then passes
through filters from which the dust is automatically removed
either by compressed air or by mechanical agitation. “These
measures result in both a clean ship and a clean terminal and
surrounding area,” Johansson says. Wider environmental benefits
also result from the fuel economies and associated reduced
emissions delivered by the use of larger vessels for the ocean
phase of bulk cargo carriage.
“This sort of flexible solution can
increase the capacity in a port without the
need for any new developments in the port
area, while any future demand for
increased port capacity can very easily be
met by deploying additional offshore
terminals and barges,” Johansson says. “The
high cargo handling capacity of the system
cuts time spent in port, a great benefit
appreciated by charterers and those
concerned with the local environment.
Furthermore, should the need for a floating
terminal cease at the port for which it was
originally intended, it can easily be moved

Johansson highlighted a case study as an
example: when one of Australia’s largest
steel producers, OneSteel Ltd, wanted to
increase its iron ore export capacity at
Whyalla in South Australia, it had to
address the problem of draught
restrictions at the loading quay. With rising
freight rates it was considered necessary
to be able to use larger vessels of up to
180,000dwt. Dredging a deeper channel
into the existing export terminal was
considered to be too expensive, and a
floating offshore transfer terminal was
identified as the best solution.
The arrangement finally selected
comprises two 10,000dwt self-unloading barges (SUB) and
Spencer Gulf, a floating offshore transfer barge. The two SUBs
operate a shuttle service, transferring iron ore from the existing
export quay to Spencer Gulf, which then transfers the ore into
the ocean-going export vessel. Cargotec received orders for the
self-unloader equipment in May 2005. The new system went live
in 2007 and continues in successful operation.
The two SUBs, Barnagarla and Middleback, are of a flat top
design, each equipped with a MacGregor gravity type self
unloading system including a large deck hopper which is loaded
from the shoreside loading facility. Unloading at Spencer Gulf is
achieved initially by gravity flow when the hydraulically operated
basket gates are opened in the bottom of the barge, feeding the
cargo to the longitudinal conveyor belt.
From the longitudinal conveyor belt the cargo is fed to a
slewing and hoisting boom conveyor for transfer to the receiving
hopper on Spencer Gulf. From this hopper, the cargo is conveyed
on two inclined belt conveyors onto a 39m retractable boom
conveyor reaching into the export vessel.
The loading procedure starts with Spencer Gulf being towed
out to the open sea and moored alongside an arriving Capesize
bulk carrier. At the same time the first shuttle barge loaded with
iron ore is also towed out and moored alongside Spencer Gulf.
Cargo is transferred from the shuttle barge on to the transfer
terminal and then on to the Capesize vessel at a rate of 5,000
tonnes per hour. With two alternating shuttle barges, one
loading ashore while the other is unloading offshore, a fast and
efficient cargo transfer operation is achieved.
The entire offshore cargo operation, from the SUB, via the
floating terminal and into the Capesize vessel, can be handled by
one operator. This is achieved by the use of state-of-the-art
electrical control systems and video monitoring systems.

The system was initially protected with chrome carbide hardfaced
weld deposit overlay, which achieved a minimal service life
of 9 to 12 months.
Kingfisher-Industrial designed, manufactured and installed a
replacement system using K-ALOX, a high alumina ceramic lining
system with an excellent rating for resistance to all forms of
abrasion and plays a vital part in protecting plant when bulk
solids or by-products are conveyed or processed by mechanical,
pneumatic or hydraulic means. This system is ideal for use on

CSL to transship 8 million tonnes per year in single project
Pointe-Noire, QC: The largest dry bulk transshipment operation
in Canada is currently taking place in the bay off this
community on Quebec’s north shore, and Canada Steamship
Lines’ (CSL) Atlantic Superior is in the middle of it — literally.
The Handysize self-unloader runs around the clock from
customer Consolidated Thompson’s dock, shuttling iron
ore concentrate to Capesize vessels anchored a nautical mile
away. The Atlantic Superior completes a load-discharge cycle
every 24–28 hours, delivering 30,000 tonnes of export ore
each time; the crew uses the ship’s remote-control unloading
boom to trim the load. It takes six trips to load a
“While CSL has become synonymous with specialized
cargo handling, including pioneering transshipments in the
1980s, the sheer size of this operation is noteworthy,” said
CSL’s vice-president of marketing, Tom Brodeur. “The
Atlantic Superior will make more trips in a month than
most vessels make in a year.”
The first Cape was loaded in late June, and now, a
million tonnes into the project, ship and crew have settled
into a rhythm necessary to meet the demanding schedule.
“The transshipment target is for eight million tonnes a
year,” said Brodeur. “That’s a demanding number by any
measure. Fortunately, we have the crew and the knowhow
to meet the customer’s objective.”
Tailor-made FTS by Coeclerici guarantees
future expansion for PT Berau Coal
Indonesian coal production has increased in recent years,
currently making the country the world’s largest exporter of
thermal coal, writes Capt. Giordano Scotto d’Aniello, Head of
Commercial Department, Coeclerici Logistics, Milan, Italy.
Demand is expected to be increased further by domestic
power plants. Coal for power generation accounts for more
than 60% of Indonesia’s total coal consumption, and Indonesian
major coal producers are all forecast to produce more coal this
year (sourced from Reuters). Worldwide demand for power is
growing: Indonesia, India, China, South Africa, Vietnam are some
examples of countries whose power consumption is expected to
In such a scenario, the Indonesian company PT Berau Coal,
the fifth largest coal exporter in the country, is planning to
significantly increase its coal production.
Established in 1983, PT Berau Coal has its production site in
the Berau area, East Kalimantan, within the concession awarded
to the company by the Government of Indonesia.
The total coal production, apart from the portion dedicated
to the internal consumption, is commercialized and exported to
countries such as Chile, China, India and Japan, just to name a
Berau plans to boost its coal production passing from the
current annual volume of 15mt (million tonnes) up to 30mt, over
the course of around five years from mid 2011.
In order to support and guarantee the future expansion of
its annual throughput, PT Berau Coal has requested Coeclerici
Logistics to design a tailor-made offshore transshipment solution
for loading coal into ocean going vessels (‘OGV’).
The solution Coeclerici proposed to PT Berau was a
Floating Transfer Station (FTS).
The Floating Transfer Station was conceptualized and designed
by Coeclerici Logistics, and patented in various countries
The FTS solution results in better stability therefore enabling
the facility to operate in more adverse weather conditions.
ANOTHER INNOVATION FROM COECLERICI
Coeclerici Logistics’ investment is estimated to be in the range
of Euro 20 million. The contract, signed in December 2009, has
further strengthened Coeclerici Logistics’ presence in Indonesia
and reconfirms the company as a key provider of off-shore
logistics services to the major Indonesian coal producers.
The agreement provides for a minimum guaranteed quantity
of about 40 million metric tonnes during its ten years duration.
The FTS will be able to perform a loading rate in excess of
30,000 metric tonnes per day.
