“…Lee and Song [8] reviewed shipping container transport in global supply chains. They emphasized that the dynamic operations and uncertain activities of long-distance container shipping pose challenges to the quality of shipping services, as well as that shipping operations and performance are affected by increasing concerns about the social and environmental impacts.…”

“…They emphasized that the dynamic operations and uncertain activities of long-distance container shipping pose challenges to the quality of shipping services, as well as that shipping operations and performance are affected by increasing concerns about the social and environmental impacts. All these issues bring challenges to the container shipping industry [8]. Rødseth et al [9] studied the impact of density savings in container handling operations on the time spent and ship emissions in ports using data provided by Norwegian container terminals.…”

The literature indicates that a 20% reduction in the weight of empty 40-foot shipping containers would result in $28 billion of fuel savings, along with a 3.6 exajoule reduction in the energy demand over containers' 15-year lifetime. Decreasing the energy demand and thereby greenhouse gas emissions by utilizing lightweight shipping containers has been an unexplored strategy. In this regard, this study investigates the possibility of further reducing the weight of an empty container without compromising the structural integrity, strength, and function of a traditional steel container. This research finds that up to an 80% reduction in weight is possible by producing shipping containers with composite materials. This research presents the new design of a 40-foot container made of carbon fiber laminates. The tare weight of a traditional 40-foot shipping container is around 3750 kg. On the contrary, in this research, the weight of a composite design of the same container is calculated to be around 822 kg. Additional tests with various loads, such as lifting the container and stacking loads onto the composite container, are performed to explore the strength and buckling issues of the design presented in this study. The analyses reveal that the composite shipping container is a highly promising candidate for reducing greenhouse gas emissions, providing fuel savings and thus reducing the operational costs of transportation.

“…Martínez‐Zarzoso and Bensassi () study how the piracy risk may cause extra ocean transportation costs, and Helmick () discusses how the global supply chain may be disrupted. An extended literature review on maritime safety and security can be found in Lee and Song (). The work on quantitative operations models of the battle with piracy now attracts more attention, but the results are still scarce.…”

Evasion policies for a vessel being chased by pirate skiffs

Piracy attack is a serious safety problem for maritime transport worldwide. Whilst various strategic actions can be taken, such as rerouting vessels and strengthening navy patrols, this still cannot completely eliminate the possibility of a piracy attack. It is therefore important for a commercial vessel to be equipped with operational solutions in case of piracy attacks. In particular, the choice of a direction for rapidly fleeing is a critical decision for the vessel. In this article, we formulate such a problem as a nonlinear optimal control problem. We consider various policies, such as maintaining a straight direction or making turns, develop algorithms to optimize the policies, and derive conditions under which these policies are effective and safe. Our work can be used as a real‐time decision making tool that enables a vessel master to evaluate different scenarios and quickly make decisions.

A flow‐first route‐next heuristic for liner shipping network design

2018

Having a well‐designed liner shipping network is paramount to ensure competitive freight rates, adequate capacity on trade‐lanes, and reasonable transportation times. The most successful algorithms for liner shipping network design make use of a two‐phase approach, where they first design the routes of the vessels, and then flow the containers through the network in order to calculate how many of the customers’ demands can be satisfied, and what the imposed operational costs are. In this article, we reverse the approach by first flowing the containers through a relaxed network, and then design routes to match this flow. This gives a better initial solution than starting from scratch, and the relaxed network reflects the ideas behind a physical internet of having a distributed multi‐segment intermodal transport. Next, the initial solution is improved by use of a variable neighborhood search method, where six different operators are used to modify the network. Since each iteration of the local search method involves solving a very complex multi‐commodity flow problem to route the containers through the network, the flow problem is solved heuristically by use of a fast Lagrange heuristic. Although the Lagrange heuristic for flowing containers is 2–5% from the optimal solution, the solution quality is sufficiently good to guide the variable neighborhood search method in designing the network. Computational results are reported, showing that the developed heuristic is able to find improved solutions for large‐scale instances from LINER‐LIB, and it is the first heuristic to report results for the biggest WorldLarge instance.
