Vessel intelligent transportation maritime service portfolios in port areas under e-navigation framework

In this study, to satisfy the urgent demand of vessel transportation marine service that are more standardized and intelligent, the vessel intelligent transportation maritime service portfolios in port areas (VITMSPPA) under e-navigation framework are proposed. First, we analyzed the qualitative description of vessel transportation maritime services in the maritime service portfolios. Thereafter, by combining the demand of e-navigation users and the vessel traffic service user’s guide, we propose the logical demand and structure of the VITMSPPA. Second, based on this structure, a data model of VITMSPPA is established, which tally to the common maritime data structure. Third, considering the heterogeneity of VITMSPPA data sources and the characteristics of port traffic data, a data lifecycle management model is constructed to obtain intelligent maintenance of VITMSPPA data. Finally, taking Tianjin port in China as an example, the VITMSPPA is designed based on the electronic chart display and information system using VC++ and MySQL. The simulation experiments are carried out in the different process of vessels entering and leaving port. The results show that the proposed method can provide active, real-time and efficient vessel transportation maritime services for vessels.
