Ontwerp van een 'high performance' containerterminal lay-out.
Report 97.3.LT.4929, Transport Technology, Logistic Engineering.
This report describes a 'high performance' layout of an automatic
container terminal. The transport on the terminal takes place with
automatic guided vehicles (AGVs). The stack of the 'high performance'
terminal consists of an importstack and an exportstack. The stacking lanes
of the import- and exportstack are continuously constructed and are
separated by an intermediate path with transferpoints which are destined
for AGVS. In the stack overhead travelling cranes are used so that the
AGVs can manoeuvre unhampered at the transferpoints.
The design of the terminal comprises the layout of the stack and the AGV
traffic network inclusive the handling platforms. The routing of the AGVs
at the terminal is based on a logistic analysis of the AGVsystem. The AGV
traffic network is designed on the basis of the AGV routing. The layout of
the AGV traffic network consists of modules.
The routing of the AGVs and the layout of the traffic network of the AGVs
are highly influenced by on the loading process of a deepsea vessel.
The loading process is the most critical process because of the rigid
loading order of the exportcontainers. For this loading process short
routes are designed for loaded AGVs, so that the process can be controlled
better. The loaded AGVs drive directly from the seaside transferpoints
towards the handling platforms at the backside of the quay-cranes. The
handling platform of the quay-crane consists of a turn-table for the
parallel rotation of the loaded AGV with the quay. The orientation-order
of the container can also be solved by the turn-table. The empty AGVs drive
from the handling platforms of the quay-cranes via special roads under the
quay-cranes, around the traffic network of the loaded AGVS, to roads at
the backside of the sea-side transferpoints of the exportstack. So the
routes of the empty and the loaded AGVs are coupled by the sea-side
transferpoints of the exportstack and the handling platforms of the
quay-cranes. The separation of the empty AGVs and the loaded AGVs
during the loading process of a deepsea vessel will benefit the control of
the loading process. The parallel parking places for the loaded AGVs near
the handling platforms at the backside of the quay-cranes facilitate the
realization of the loading order of the exportcontainers in the deepsea
vessel. The layout of the traffic network between the exportstack and the
quay-cranes is also optimized, because crossing AGV
traffic is uncoupled.
During the unloading process of the deepsea vessel, the loaded AGVs drive
from the handling platforms at the backside of the quay-cranes, along the
exportstack, towards the transferpoints in the intermediate path. The
empty AGVs drive from the transferpoints in the intermediate path, along
the exportstack. towards the roads under the quay-cranes.
A thorough analysis of the terminal transportsystem has produced a
containerterminal layout, which offers good possibilities for intensive
terminal transport with AGVS.
