This study aims to compare and analyze the global container service network of the new “GEMINI Cooperation”, formed and operated by Maersk and Hapag-Lloyd from Feburary 2025 with the existing three major container alliances(2M, Ocean, THE Alliance) from a network perspective. The analysis results indicate that the network structure of the “GEMINI Cooperation” has been strategically restructured through its differentiation from the existing three major alliances, which is evaluated as distinguishing itself from existing alliances. This restructuring is assessed as an attempt to secure a new competitive advantage in the global logistics environment. In particular, this study quantitatively analyzes structural differences among alliances using SNA techniques, confirming that the distinctive network formation of GEMINI Cooperation is being developed in a direction that strengthens its differentiation from existing alliances. The analysis highlights the centrality of Shanghai Port in China, along with the rise of key Vietnamese ports centered around Tanjung Pelepas Port, in which Maersk's terminal subsidiary APMT holds equity shares. Additionally, the emphasis on new hub ports such as Jebel Ali and Algeciras signifies strategic changes within the GEMINI Cooperation network. On the other hand, the decreasing centrality of Busan Port, Singapore Port, Hong Kong Port, and Kaohsiung Port suggests a diminished role for these ports within the GEMINI Cooperation network. In response to these changes, each port must adopt strategic measures to enhance competitiveness and adapt to the new network structure.
