tential for cost reduction. Even if they
intend to take ship unloading operations into their own hands, this usually
depends on public concession from the
port authority. The local, mostly smaller
ship berthing jetties are forced to be
multifunctional. In addition to the dry
bulk commodities, other goods such
as general cargo, fluids and containers must get handled on the same jetty.
These port authorities are often very
reluctant to grant exclusive or partial
concessions to smaller private operating companies which, according to their
specific needs, would install their own
permanent facilities on the jetty, probably obstructing other operations.
CURRENT APPLIED SOLUTIONS
Grab Shelves: There are usually multipurpose mobile cranes, equipped with
grab shelves, available at most ports
which in principle enable the unloading

of grains. Grab shelves can also be operated by the ship deck gears, without recourse to shore side mobile cranes. The
ship discharged grain is collected on the
pier, either directly or through receiving
hoppers onto trucks or to an onshore installed conveying system for the downstream transportation.
This type of ship unloading of cereals, according to today's levels of
available technology, requires the
lowest investment in equipment and
infrastructure. This mode of vessel
discharging is likely to be banished
due to the increasingly stringent environmental laws. During the swing
maneuver of filled and often overfilled
grab shelves from the ships hold to the
shore receiving system, depending on
the thoroughness of the movement and
its speed, inevitably dust emissions and
product spillages occur. Even worse are
the dust clouds which develop when

emptying the grab shell by opening it.
These losses can get up to integer percentages of total cargo weight.
Along with the unwanted pollution,
these losses also lead to significant
shrinkage in cargo asset value. Ports certified according to ISO 14002 ban such
methods of ship unloading. Avoiding the
dust emissions from grab shells operation can only be obtained by very costly
de-dusting and aspiration systems on
the shore side receiving hoppers or by
extremely slow gently moving the grab
shell, at the expense of unloading capacity. This leads to a considerable loss of
operational efficiency, finally resulting
in increased expenses for longer ship
berthing duration.
Mobile, portable pneumatic unloaders: Other mobile ship unloading
equipment for grains, as an alternative
to the grab shells, are the pneumatic
suction unloaders. These are usu-
