                          MODERN SHIPPING TECHNOLOGY

        When the world seaborne trade started to boom after World War II, it soon became clear
that the general cargo vessels could hardly cope with the increased traffic efficiently.

         It became evident that the cargo flow could be increased by improving the performance
in port, i. e. by decreasing the time required to load and discharge a vessel.

       New cargo handling techniques had to be developed, therefore aiming at quicker cargo
handling procedures and a reduction in labour.

Unit Load Concept. General or break bulk cargo, which consists of any arrangements of boxes,
crates, bags, drums, cartons. etc., was formerly transported by the so-called general cargo
vessels. The weight and the dimensions of the cargo were limited to the lifting capacity of the
shore-based crane or by the derrick of the ship. Cargo stowage in the holds was carried out
manually. Research to decrease ship's time in port (or turnaround time) has led to the
introduction of the Unit Load Concept (ULC). The pallet and cargo handling techniques such as
pre-strapping, pre-slinging, and machines like the fork lift truck (FLT) form the basic
components of ULC. The basic idea of the ULC is that small, individual items of cargo could be
coupled, stacked, and slung together to bigger units. These can be handled easily as they require
less time for handling in the port on the quay.

Side loading and the multi-purpose vessel. The application of ULC techniques led to the new
developments of ships, such as the side loader and the multipurpose vessel. The use of side
loading vessels to transport palletised break bulk cargo, reduces the turnround time
considerably. The cargo can be loaded and unloaded quickly, due to the elimination of the so
called lift-on/lift-off procedures and due to the modular shape or the cargo. One possible
disadvantage of this method is the possible loss of space in the holds.

The multipurpose ship is a further perfection of the former general cargo vessel. The basic
features of this type of ship are: wide hatches, more easy operated hatch covers, increased
capacity of the ship's lifting equipment, possibility of carrying heavy lifts on deck, shifting of
the wheelhouse superstructure to aft or three quarters aft to ensure less obstructed cargo
handling in port. The capacities of multipurpose ships range from 10 to 30,000 dwt.

Containerisation. During the First and the Second World War small wooden and iron boxes,
the so-called containers, were used to ship ammunition for the Allies to the various fronts. In
the 1950's the container concept started with the introduction of one type of container which
was loaded on and off the vessels plying between some ports on the coasts of the United States.
This was soon followed by first transatlantic crossings, and the so-called Container Revolution
started. The basic unit of containers is the 20 foot container. The container storage capacity is
usually expressed in TEU (twentyfoot equivalent unit). Various types of containers exist, not
only for the transportation of break bulk cargo, but also for refrigerated, liquid and, on a
smaller scale, bulk cargo. As well as containers, other units of break bulk cargo, such as ro-ro
units and barge loads, belong to this group.

The first ships to carry containers were the modified general cargo vessels mentioned. Soon
after the transatlantic crossings started, the first fully cellular container vessels were built. At
present the following types may be distinguished: 1st generation of container ships, i.e. the
original ships; 2nd generation, which has a capacity ranging from 800-1500 TEU, and 3rd
generation, with a capacity ranging from 1700 to 3000 TEU and over.

Cargo handling equipment has been adjusted to fulfil the requirements of the container concept.
The traditional cargo handling equipment could no longer cope with the bigger and heavier
units, so special equipment had to be designed. This equipment includes portainers, shiptainers,
transtainers, straddle carriers, container fork lift trucks, side loaders, etc.

With the introduction of the container in international transportation, the so-called door-to-door
concept of transportation became a reality. This system involves the loading of a container at the
producer's premises from where it is transported to the consumer without any transfer of
commodities during that transportation.

Door-to-door transport is also identified as Full Container Load (FCL). This is to distinguish
containers which arrive at a terminal loaded with cargo for one consignee or consumer only.

In many cases, however, container loads are less than one FCL and are called Less than
Container Load (LCL).The Container Freight Station (CFS), or groupage shed, is- the place
where full container loads are assembled or dissembled, including stuffing/stripping of

Roll-on/roll-off concept. Although in previous centuries more or less similar types of vessels
were in existence, it was only during World War II that the so-called ro-ro concept was
applied fully for the first time. The ro-ro concept could best be described as follows. Ro-ro
stands for the method of cargo handling by which cargo is not lifted on and off board, as in the
case of lift-on/lift-off vessels, but is lifted and moved on and off the ship horizontally, on its
own or on temporary wheels, via the ramp, which is a hinged door being lowered onto the

Some ferries (ro-ro vessels that carry passengers, private automobiles and wheeled cargo on
the shorter hauls), are equipped with a bow ramp and some even with both bow and stern
ramps. The first types of ro-ro vessels were soon replaced by modern short and deep-sea ships
of a more sophisticated design, equipped with quarter ramps, and more recently, slewing

The ro-ro ship proved particularly profitable during the congestion of the Middle East and
African ports in the 1970's, because they are not dependent of port facilities, such as cranes.

Barge - carrying vessels. A further development of the container my be found in the barge
carrying vessels. In this system the mother ship arrives in the port area, where she loads and
unloads a certain number of barges and leaves the port again. These operations do not have to be
executed alongside a berth, since the barges are floating. The only requirement for barge
handling procedures is a relatively large area of water protected from waves higher than about
one metre. The additional advantage of this system is the relative independence of port
facilities and the relatively easy further transportation from the port to the consignee in the
hinterland and vice versa by means of inland waterways. The major types of barge-carrying
vessels that have been developed are the Lash and the Seabee type ships.

The introduction of the above shipping technologies has allowed for the development of the
so-called multi-modal and intermodal services in the world transportation of goods.
