Container ports are indispensable parts of the container transport operations. In terms of container transport operations even better port services are desired to provide viability of reliable liner shipping service. Therefore, port competition to supply better port services is one of the natural consequences of the container transport evolution in the globalisation era. This thesis offers a port competition analysis as total transportation time and cost based between the container ports which serve to collided hinterlands with the integration of offshore container port system (OCPS) and ultra large container vessels (ULCV). An OCPS adaptation is assumed to create offshore container port related an inter-port container competition with other conventional container ports which can handle ULCVs. This OCPS is going to complicate competition game and conditions even much more between ports. The methodological approach of this study aims to develop a hybrid port competition analysis model to analyse port competition in terms of commercial and operational aspects. The model is divided to two different methodological stages. First proposed method is to apply total transportation time and cost based door-to-door container network analysis in order to determine the competitiveness of the given port alternatives. In this approach, according to total time and cost values, the weights of each competitive port are determined to define the position of ports in the competition in order to attract interest of the industrial customers. Operating costs, voyage costs, cargo handling costs and hinterland transportation cost, and also port construction costs are considered as main criteria to clarify the ports’ position in the competition. Second method is to develop a game theoretical strategy concept to apply on the port competition regarding to lucrativeness and investment opportunity expectations of the port authorities.Integration and comparison of the both methodological approaches is going to provide valuable findings to analyse competitiveness level of container ports more accurately. Outcomes of this research may help for future business development strategies of port authorities, port operators, shipping liners and private and public port investors. This study is expected to provide a clear holistic comprehending about the underlying dynamics of the port competition for all counterparties involved in container transport operations.
