Containerships gigantism is a phenomenon that troubles shipowners and container terminal operators around the world. Its benefits, such as the economies of scale, make smaller containerships obsolete and less sustainable, due to the reduced cost per TEU, while container terminal operators face problems regarding the proper adjustment of the terminal infrastructure in order to be able to serve mega containerships. The purpose of this thesis is the analysis of the containership gigantism, with focus on the reasons and consequences that define it, while combining published data regarding liner shipping, in order to make an approximate analysis on demand. A mathematical model is created, with additional formulae to supplement it, which are used on hypothetical scenarios in order to find the optimal size per case, on the main sea trade routes.
