Shipyard Layout

The past two or three decades have seen the emergence of a substantial
number of new shipyards, primarily in Asia and Eastern Europe, that
have been specifically planned to construct the larger ships being ordered
today, using contemporary shipbuilding practices and production methods.
A number of traditional shipbuilders have also established new yards
where they can also build larger ships and/or exploit the new technology
and production methods. In general the remaining shipbuilders will
have had to re-configure their site in order to utilise new technology
and improve production, whilst continuing to build ships. In many
cases the latter will still be restrained as to the size and type of ship
that can be built. ึ
An ideal layout for a modern shipyard is based on a production flow
basis, with the yard extending back from the river or shore at which the
berths or building dock are located. The furthest area from the berths is
reserved for the material stockyard, and between the two are arranged in
sequence the consecutive work and shop processes. Too often existing ship-
yards follow the river bank, and are restricted by their location in a built up
area or the physical river bank slope from extending back from the river, so
that modified production flow lines are required.
Planning a new shipyard, or re-planning an existing one, will involve deci-
sions to be made on the following:

Size and type of ship to be built.
Material production per year to be achieved.
Material handling equipment to be supplied.
Machining processes to be installed.
Unit size and weight to be fabricated and erected.
Amount of outfit and engine installation to be undertaken.
Control services to be supplied.
Administration facilities required.

Shipyards usually have a fitting out basin or berth where the virtually
completed ship is tied up after launching and the finishing off work and
static trails may be carried out.
