C.A. Welsing Conceptual design of the Puerto América combi-terminal. Optimisation of the quay configuration by means of simulation.
Masters thesis, Report 2000.LT.5347, Transport Technology, Logistic Engineering.

Puerto América is a proposed new port at the entrance to Lake Maracaibo in Venezuela. Lake Maracaibo is a semi-enclosed estuary with a very narrow and shallow strait connection to the sea. To enable sea ships to enter the lake, an entrance channel was dredged in the 1970's. As a result the lake suffered from increased salinity, which has developed into a serious environmental problem.
To solve this environmental problem it is proposed to close the entrance channel. This would mean that sea ships can not enter Lake Maracaibo any longer. Therefore, it is proposed to develop new port facilities at the entrance to the lake. One of these facilities is a combi-terminal. Here breakbulk as well as containers can be handled.

The objective of this report is to discuss the development of conceptual designs of the Puerto América combi-terminal for scenarios of 2005 and 2015. These designs consist of the following elements: For the optimisation of the quay length in combination of the type and number of equipment, a simulation model is developed.

First a research of port and terminal planning techniques is made. These methods and techniques form the basis for the development of the designs. Next a detailed cargo and traffic analysis is made. The cargo is categorised by its handling rates and weight. The vessels are categorised by length and average parcel size. With the resulting cargo and traffic forecast, initial designs are made. This results in two different configurations for the quay: To optimise and evaluate the different configurations, a simulation model of a combi-terminal is developed. With this simulation model it is possible to determine the required number and type of equipment at the quay for a particular scenario. Further, it can be used to determine the minimum required quay length and to make an estimate of the rail requirements at the quay.

Finally, the following terminal designs are chosen for the Puerto América combi-terminal:
