“…The usual solutions recommended for these demands of the container transportation industry are port expansion projects, faster, technological and long-reach handling equipment, dredging, and enhancement of existing port facilities and hinterland connections (Harrison et al, 2000, Notteboom and Rodrigue, 2009, Rodrigue, 2011, Imai et al, 2013, Merk et al, 2015, Helmy and Shrabia, 2016, Merk, 2018, Park and Suh, 2019, Lee et al, 2020. Another approach is to develop offshore transfer hubs to eliminate the dimensional problems caused by mega containerships, and to contribute to an efficient understanding of container transportation (Ircha, 2001, Pluijm, 2014, Pachakis et al, 2017, Kurt et al, 2021. Kim and Morrison (2012) examine the classification and economic feasibility of offshore port concepts in their study.…”
