After a brief background about the development of containerization in recent decades, this chapter reviews the current characteristics of liner shipping networks under three main themes. First, it provides an overview of the different service types of shipping lines and dynamics in liner service configuration and design. Second, a global snapshot of the worldwide liner shipping network is proposed by means of vessel movement data. The changing geographic distribution of main inter-port links is explored in the light of recent reconfigurations of liner shipping networks (e.g. multiplication versus rationalisation of port calls). We also discuss the position of seaports in liner shipping networks referring to concepts of centrality, hierarchy, and selection factors. The chapter concludes by elaborating on the interactions and interdependencies between seaport development and liner shipping network development notably under current economic changes.
