To satisfy the transportation service request of clients and to control the associated costs are the main targets of marine container transportation industry. To achieve the transportation service for clients, plenty of participants and procedures are involved in the Marine Supply Chain (MSC), leading to the need of exchanging a huge amount of information. This study is focused on how and what kind of information sharing should be exchanged in these participants and procedures of Maritime Supply Chain. We use UMM (UN/CEFACT Modeling Methodology of ebXML business process) to investigate the business processes between participants in Marine Supply Chain. We also conducted a case study in an important location of maritime supply chain, i.e., Port Container Terminal to discuss about the information sharing content and sharing pattern in MSC processes. The result shows that in the marine cargo delivery process, Port Container Terminal is responsible for Berth Schedule Planning, Berth Planning, Yard Planning and Gate Planning to achieve the container transport service for the clients. Therefore, plenty of participants and procedures have to be involved in the Marine Supply Chain, and plenty of information have to be interchanged. However, beside Customs Clearance procedure, there are no common information technology platform and standard for information interchange in marine container transportation industry. To improve the service quality of domestic marine cargo delivery, we have to establish an information sharing system. Moreover, I personally hope this study can be used as a reference of information system analysis and design. Improving the information sharing standardization and building information sharing pattern can simplify and improve the procedures of marine cargo delivery system.
