Ports are at the crossroads of many activities, modes, and stakeholders, and are actively becoming digital hubs. Today, digital and physical connectivity go hand in hand. The port could beneft from taping the opportunities arising from digitalization and data integration since it helps to leverage external knowledge, engage stakeholders, create new decision- making anchors, lower the risk of certain investments, boost productivity and cut costs, and accelerate greening and digital transition, generating possibilities for just-in-time operations and optimizations. The chapter aims to apprehend the use of data science in the port sector. The state of the art in Brazil and Portugal are diferent. Even inside Brazil, there is no homogeneity of ports in the usage of digital infrastructure, cloud computing, or artifcial intelligence. The existing inequalities hinder general co- operation between nations but, at the same time, reveal opportunities to approach specifc nodes in the international supply chain.
