The content of book involved types of craft, reader's actions, glossary and bibliography. Ultimate authority hardly needs to be pointed out that a separate volume might will be written about almost every single entry contained in this book, so it should be understood that each entry is basically an identification only, although often with some historical background, and where necessary a more …

This paper addresses two coordination problems that exist in the waterborne transport in large seaports, the long time of stay of inland vessels and insufficient terminal and quay crane planning with respect to their sailing schedules. A novel coordination model is proposed and tackled using logic-based Benders decomposition and Large NeighborhoodSearch. In addition, a closed-loop perspective i…
Offshore exploration and production in the Gulf of Mexico (GOM) is supported by a large number of service vessels characterized by complex logistical patterns, a large number of shorebases and demand points across an expansive geographic area, and dynamic time-varying activities. No quantitative data is available on the spatial and temporal distributions of service vessel activity in the GOM, a…
This paper investigated if differences of the profits of the Korean and other global shipping companies were affected by the shipping route specialization. A panel data model was applied to nine shipping companies during the 2009-2015 period, to determine to what extent freight rate, bunker fuel prices, scale economies and chartered vessel ratios affected the profits. The results showed freight…
One of the most important issues in Transhipment Container Terminal (TCT) management is to have fairly reliable and affordable predictions about vessel arrival. Terminal operators need to estimate the actual time of arrival in port in order to determine the daily demand for each work shift with greater accuracy. In this way, the resources required (human resources, equipment as well as spatial …
The Upper Mississippi River (UMR) is an important artery for transporting export-destined grains from the north central United States to lower Mississippi River ports. The increased traffic on the UMR system has led to increases in congestion, delays at locks and longer vessel proceeding times. We analyze systematically the arrival, waiting and lockage time of vessels at the locks of UMR. We co…
This paper proposes new equations to calculate shipping costs and slot distribution when working in a shipping alliance environment. The fixed costs and capacity are shared by a predetermined ration of contributed containerships for the jointly-operated service route. The exchange rate of slot-exchange pattern depends on the relative ration of both round-voyage sailing days. Each contributing …
Containerization of bulk cargo has gradually emerged in recent decades, particularly along the US–East Asia trade route (China, Japan and South Korea). One of the background factors in the emergence of this phenomenon is an imbalance between eastbound and westbound container cargo movements along this route. Nonetheless, the factors that affect containerization have not yet been identified. W…
