The fact that the operation of ULCVs also involves costs and impacts on ‘external’ systems is often overlooked. Any negative effects are still dealt with rather peripherally, and so it is primarily the cost effects of operating ULCVs from an isolated shipping company perspective that dominate the discussion. While this size segment consisted of only eight Maersk E-class vessels with a total capacity of approximately 143,000 TEU before 2012, more than 160 ULCVs with a total capacity of over 3.2 million TEU were already in service at the beginning of April 2021 (CRSL 2021b).īy using ever larger vessels, liner shipping companies are taking advantage of the so-called economies of scale, which have enabled to continuously reduce costs per TEU transported and have given the ULCV its raison d’être (Ge et al. Particularly striking in this regard is the rise of the dimensionally largest ships, the so-called Ultra Large Container Vessels or ULCVs. Since 2010, it can be observed that the number of container ships is only increasing rather slowly, while the average ship size in terms of nominal capacity continues to rise almost linearly. During this time, the number of container ships also increased sharply, at times at double-digit annual rates. Especially in the years prior to the global financial and economic crisis of 2008/2009, annual increases in total capacity were almost continuously above 10%. ![]() Over the past 25 years, the slot capacity of the global container ship fleet has increased continuously as a consequence of a steadily growing number of vessels that have become larger and larger on average. ![]()
