De drijvende containerkraan
Masters thesis,
Report 2004.TL.6863B, Transport Engineering and Logistics.
The higher requirements of and the prospect on a better information exchange
in container transport leaded to research on the idea of a floating container
crane for board-board transfer. The idea was got by a brainstorm session,
organised by the projectgroup "The Container Terminal of the future".
The object of this study is a design of a floating crane for container handling
in the Port of Rotterdam in order to get more feeling on the feasibility of
this concept.
The report is divided in three parts. The first part describes the scope
of the design and the background of the floating crane concept for
board-board transfer. Some starting points for container logistics are
made.
The second part contains the development of handling concepts for the
floating crane. In this part three concepts with different characteristics
are composed. The first concept is the original crane concept en is
defined as a reference concept. The second concept is a simple concept
with a fixed crane. The third concept is a more enlarged concept with a
moving crane. The three concepts are evaluated with a multi criteria
analysis. The concept with the fixed crane is selected owing to the best
price-performance ratio.
In the third part of the report the selected concept is worked out in more
detail. The most important topics are station keeping and stability. The
crane is kept station by winches that are connected to the deep sea
vessel. Furthermore the stability of the crane is researched. Finally the
productivity and the costs of the concept are estimated.
The final conclusion is that the floating crane seems to be feasible.
The main characteristics of the floatin crane are:
- The productivity of the crane is around 24 container moves per hour.
- The investment costs are valued at 13,5 million euro.
- The total handlings costs of the floating crane are around the 30,-
euro per TEU.
- The total handlings costs of the floating crane are around the 10,-
euro per TEU cheaper than the total handlings costs of the deepsea
terminal.
