LACK OF SLACK?Our results show that it is the ‘unexpected’ and ‘unanticipated’ -e.g., a natural disaster; a war; a tsunami; or COVID19-that poses the greatest risk to carriers: Intense competition amongst them, geared to short-term profit maximization, coupled with the fine-tuning of capacity management within alliances, does not allow them the luxury of affording built-in buffers, or slacks, that could ‘absorb’ the unexpected. Not unexpectedly therefore, COVID19 has been the greatest risk factor of all times, mitigated –quite profitably one should add—by the joint capacity management of global shipping alliances.

Before, ports used to be ‘city ports’, particularly in cities blessed with a river. Growth in trade and ship sizes eventually obliged them to move downstream, in river estuaries, where more space was available. Cities thus became ‘port cities’. Of recent, we observe port activity returning back to the hinterland in the form of inland terminals and dry-ports. However, the relationship between the port and its city, or vice versa, has never been easy. The port needs autonomy, the city requires ‘control’.
Moreover, both port and city need to develop their port and urban plans, and this requires land which can be demanded and contested by both. Can a city and a port coexist in harmony? Carola and Maurice try to answer this through the compilation of eight excellent papers in this new MEL Special Issue. Congratulations and thanks to both guest editors and all the contributors to this new MEL milestone.

I have written on this issue before but, again, here is an excerpt from my new work, to appear shortly.
The type of competition we choose to adopt among our concessionaires is important. In many submissions to the European Commission, I have favoured competition ‘in’ the market, vis à vis competition ‘for’ the market, the latter being the Commission’s preference, mostly based on arguments regarding market size.
To explain. Ports are often referred to as the classic example of the so-called natural monopoly case, whereby possible market failure can justify government intervention. Under certain conditions (level of demand, cost structures and technology), a market with two or more firms can produce sub-optimal economic outcomes (for example a certain port may be too small to have two tug operators), whereas a single firm might produce the required output more efficiently. For this reason, governments often decide to move away from a multi-firm competitive environment (competition “in” the market), towards a monopolistic, albeit regulated, situation (competition “for” the market), whereby only one concessionaire is selected through competitive public tendering.
I have always argued that such public intervention in commercial decisions is wrong. And it is wrong for two reasons.
First, the sometimes-widespread corruption in the public sector may result in ‘photographic’ tenders favouring a specific bidder (often the current incumbent), effectively shutting off international or even national competitors. Thus, it is not uncommon for public tenders to end up with only one interested bidder, while the correlation between single-bid contracts and corruption in the public domain is statistically significant. Finally, the opening of the market for public contracts is one area where WTO is dragging its feet for years now, without much progress.
Second, governments, and the public administration by and large, are by far the least competent actors to decide on ‘market size’, or on the financial ramifications for private firms who would like to take calculated risks and enter a market. This is because governments lack both the information required for such decisions --a typical case of asymmetry of information and the legitimization to decide themselves on the fortunes of private risk-takers. The same is true when it comes to the efficiency of the regulatory role of the public administration (port authority): often, the latter has neither the professional competence (accounting, finance, etc.) nor the information and statistics required to assess the highly complex accounts of the concessionaire; accounts that, often, are submitted in purposely complex and lengthy form, intended to confuse the assessor.
Instead, the role of the public administration should be to set the rules of the game; to determine the conditions and quality of the services it requires (including any Public Service Obligations) and then leave it up to the private sector to decide for themselves if the market is big enough, if they see profit prospects, or if they would like to go bust. But this ought to be ‘their own’ decision, because it is ‘their own’ money, and, in the end, ‘their own’ neck on the block.

The inclusion of shipping in the European Union’s Emissions Trading System (ETS) is a game changer for ocean transportation.
The World Bank foresees that the Carbon
Emissions Trading (CET) market may develop into the world's largest commodity
trading market, expected to exceed $3 trillion in the near future. The Bank
also expects CET futures, as well as the carbon finance market as a whole, to
replace oil as the world's largest market.
We show that the link between carbon emissions trading and shipping is strong, particularly between CET and dry bulk shipping. The link becomes stronger during periods of external shocks, such as Brexit, Covid-19 and China-US trade frictions.
But how can our results be intelligently used by shipowners for greater profit? How can they support the environmental sustainability decisions of shipping companies? And how can governments include shipping in emissions trading systems?

MSC’s orderbook in particular is spectacular, five times that of the more conservative Maersk Line. This explains their ‘divorce’: Maersk has decided to invest along the supply chain while Mr. Aponte (MSC) will continue doing what he, and his father before him, did best: “shipping”. In other words, the two companies decided to invest their fathomless profits of the COVID-19 years in what each was best at: Door-to-door supply chain integration for Maersk; competitive ‘port-to-port shipping’ for MSC. The two strategies are not compatible, as they lead to two different cost structures: substantial investments in a global network of sales effort around the world, for Maersk, targeting the individual shipper, and ocean transport cost competitiveness for MSC, renowned over the years for its acquisition of new and secondhand tonnage at competitive prices.
My point here is different, though: The two graphs tell us that shipping alliances may have not been very successful, after all, in managing capacity, and regulators may be proven right in considering the (COVID19) price hikes just a “matter of demand and supply”. This could be the second reason for the Maersk-MSC divorce. Or not?

In the thrust of nations towards ever higher competitive advantage, container terminals play a pivotal and indispensable role. Technological advances and competition amongst them, have forced terminals to raise their efficiency to remarkable levels. This was not always the case: there were times, during the protectionist years following WWII, when inefficient ports were tacitly encouraged by local exporting interests, seen as protection from foreign imports. These were the days of the general cargo freighter, often known to spend half of her time in port, waiting to berth, unload and load. Seafaring was fun during those days. Today, the ship is turned around in two days and the terminal may be 50 kms or more from the city. Even if public transport did exist, the youngster would rather relax in his airco berth, or by the pool, or playing a game of snooker with his mates. At any rate, he would again be back home in a couple of weeks.
Simply put, efficiency means two things: Either we strive to achieve a certain output (i.e., number of containers handled per annum, or ships hosted in our berths) with as low a cost as possible; or, given a certain endowment of port resources (i.e., cost), we struggle to maximize the port’s output. The methodology commonly employed in this type of efficiency assessments is known as Data Envelopment Analysis (DEA): a mathematical programming approach, producing ‘frontiers’ of best practice (i.e., top efficiency), against which all other firms (in our case port terminals) can benchmark themselves; a procrustean bed, so to speak.
Whatever the case, cost control is the paramount consideration of port management. One of the ways to achieve this is to minimize the movement of containers and their handling-equipment in and around the terminal. A few examples might suffice: Minimize the turnaround time of ships (how many ship-to-shore cranes can I deploy on a large ship before I start realizing diseconomies?); Minimize container rehandles in the stacking yard (if a container departs in two hours, you may not stack other containers on top of it); minimize the distance between the berth and the stacking yard; minimize the distance an external truck must travel between the gate and the place where it must drop its export container; minimize the time a truck must wait in the parking lot before it can enter the terminal to pick up its container; and so on.
If one wants, and one must want, problems could become even more challenging: Stack containers in the yard according to the stowage-plan of calling ships; i.e., optimize ship stowage-planning and yard-planning simultaneously and well in advance, adjusting terminal-planning according to ship operations in previous ports. Yard-planning is an operations research (OR) challenge but, even in the largest of terminals, like Shanghai, Rotterdam, Singapore or Los Angeles, the problem has been efficiently solved through the development of advanced IT software. But if yard-planning is a challenge, stowage-planning may be an even bigger one: A stowage plan needs to take into account not only the ship’s port-rotation, but also a) stability considerations during loading (the clearance between the ship’s keel and the seabed, these days, may be less than half a meter, and if loading along rows is not even, touching the seabed could be disastrous); b) alliance-members’ dedicated bays on the ship; c) crane density; d) different sizes of containers; e) dangerous goods, and more. If stowage-planning and yard-planning are ‘challenges’ in themselves, trying to optimize them simultaneously is an OR nightmare. It is not by accident that my brightest students (in math and OR) work at PSA, DP World, Hutchinson and other global terminal operators.
But still we haven’t explained what are ‘dual transactions’
in container terminals.
There are two types of external trucks visiting a container terminal: those who bring export containers from the hinterland, to be loaded on arriving ships; and those who come to pick up import containers, already unloaded and waiting in the container yard. Usually, in both cases, one of the two legs of the trip is unproductive: the ballast leg, as we would say in shipping. A truck drops the container at the terminal and returns empty; another goes empty to the terminal to pick up an import container. This type of inefficiency -if we could call it that- not only leads to higher transport costs but, these days, it causes things even more important: these are the negative externalities of land infrastructure use, i.e., pollution, congestion, and road accidents. It would be interesting at this point to make a small diversion.
The drive to efficiency, as we said above, has to do with maximizing output (e.g., number of containers handled) given a certain endowment of resources (cranes, land, people). Today, however, there is a new factor entering the efficiency calculation: This concerns the minimization of negative externalities from port operations, such as sea and air pollution, noise, disturbances of sea ecosystems, accidents, impacts on local communities and on commercial activities (e.g., fishing, aquacultures, etc.), conflict with urban development plans, road congestion around the port and so on; the list goes on. All these are called ‘negative output’ of port operations and reducing them is equivalent (or it should be seen as equivalent) to increasing ‘output’.  The question of course here, as in all cases involving negative externalities, is how to price them, who should pay for them and how, and what would be the impact of higher prices on trade and welfare. But let us finish our diversion here and return to our dual transactions.
Can a hinterland consignee know which trucks take export containers to the port so that he can ‘book’ one to pick up his waiting import container and bring it to him? And can the truck going to the port to pick up an import container know who, in the hinterland, needs a truck to carry his export container to the terminal? Technically, this exchange of information shouldn’t be too difficult to organize, and a simple APP could take care of it. The impact of dual transactions on terminal management requirements, however, is considerable, and this is the problem we have tried to solve in this research, the development of which took us more than three years. This is why:
The terminal management system we have described above, i.e., stacking-berthing-gate (etc.) operations, now needs to be modified to accommodate the following dual transaction considerations: a) An incoming dual transaction (DT) truck cannot wait at the gate and needs to jump the queue; b) the truck cannot wait either at the queue of the export block to drop its container; priority should be given to it over the operations of internal terminal trucks and other handling-equipment; c) when the truck is ready to move to the import stack to pick up a container, the handling-equipment (e.g., bridge cranes, straddle carriers; reach-stackers, forklifts, etc.) should be ready and waiting and, ideally, the availability of the equipment should have been planned in advance. So, in short, if optimizing shore and yard operations jointly (we have carried out research where even gate operations are included in this optimization) in a nightmare, the inclusion in the problem of dual transactions makes the problem apocalyptic. This, because now one needs to develop a heuristic algorithm that jointly optimizes: gate; berth; stowage; yard; export/import blocks and handling-equipment deployment.
In an effort to address these issues, we have developed a bi-objective mixed integer programming model that optimizes the allocation of appointment quotas simultaneously with the deployment of (yard) cargohandling equipment. The model addresses the challenges posed by the different types of truck movement in the terminal, i.e., delivery, pickup, and dual transaction. These require different handling-equipment, involving various deadlines, and multiple priorities. To estimate the queuing length of external trucks in single or dual transactions (as well as that of internal trucks), we have set up a novel three-level vocation queuing model. For the bi-objective optimization, we propose a revised non-dominated genetic algorithm, to obtain the approximate optimal solution. Experimental results have proven the efficiency and effectiveness of our method, which outperforms all similar algorithms. We show that our vocation queuing model can estimate the prioritized queuing process more effectively in three respects: a) the 3-level queuing; b) discrete truck arrivals in the queuing system; c) non-interruption of servers. Our quota optimization design improves the model’s applicability to real cases, especially in the case of dual transactions. We finally demonstrate that the method proposed here, if adopted, could help terminal operators allocate quotas and simultaneously match the capacity of yard-handling, thus improving truck services, cost reductions and environmental impacts. The benefits to be enjoyed by port users, because of higher terminal efficiency, are only too obvious to be discussed.-

A lot of ink has been shed lately, both on the concept of (port) connectivity and on the aspirations of many ports to achieve international hub status.
The importance of connectivity in particular, is today assuming greater dimensions in view of the strength of global shipping alliances (GSA), their ability to jointly ‘manage’ the supply of tonnage, and the negative impact such power has had on the frequency of services; the number of companies calling at a port; on containership sizes; and on call sizes.
However, connectivity alone cannot explain the importance (and prospects) of a port as an international hub, its attractiveness to shippers, and its ability to develop new transshipment traffic (no matter how well connected a port is in the Arctic, or in Tierra del Fuego, it will never assume hub-port status). We argue that connectivity needs to be combined with measures of centrality, as these are derived from advanced network theory.
We thus introduce the novel concept of composite connectivity: Through an innovative use of Two-Stage Data Envelopment Analysis (DEA) and complex network theory, we first evaluate the efficiency of ‘basic connectivity’ and use this as input in the second stage, which measures the strength of centrality. To do so, we employ such network theory measures as betweenness centrality, closeness centrality, and eigenvector centrality. The “Composite Connectivity Index” - CCI is thus obtained as the ratio of (our measures of) port centrality to port connectivity. The top nine mainland China ports are used as a case-study.
Our results (and rankings) conform to the general perception on the international importance of the ports of Shanghai, Shenzhen and Hong Kong. The usefulness of CCI as a decision-support tool for ports with hub aspirations, as well as for their financiers and investors is, we believe, obvious.

[articulated from: Claudio Ferrari, Hercules Haralambides and Alessio Tei (eds.) 2022. Regulation and Finance in the Port Industry. Palgrave Studies in Maritime Economics, Palgrave Macmillan, DOI: 10.1007/978-3-030-83985-7_1].
From a historical viewpoint, the strategic significance of the port industry, both for foreign trade and national industrial development, has led many national governments to seek an active involvement in the development and control of port infrastructure. However, the scarcity of public financial resources; the unwillingness of the public sector to assume the market risk of specialization; the limited ability of the public administration to run complex, risky, and increasingly commercialised activities, such as those of container terminals; the interest of carriers in having their own dedicated terminals and, finally, the increasing appetite of the private sector (Global Terminal Operators - GTO) in the often very lucrative port terminal investments, have given way to the devolution of decision-making authority from the ‘centre’ to the ‘periphery’. A period of national port reforms has thus started in the 1980s and 1990s, which is still underway in many countries.
Port reforms range from the simple commercialization of port operations to corporatization, and all the way up to full port privatization. But the private sector’s involvement in port business has often given rise to conflict between port and city administrations, particularly municipalities, many of which still believe that it ought to be themselves the lawful managers of ‘their’ ports [During my years as the manager of the Italian port of Brindisi, I vividly remember, the then mayor of the city, and member of the port’s supervisory committee, never missing the opportunity to declare that ‘he did not participate in committee meetings just in order to raise his hand and vote, but he was coming there to actually manage the port’!].
A reversal of the devolutionary trend can however be observed, increasingly, today, i.e., a recentralization of decision-making powers, through the integration of regional ports under a single authority. The trend is being championed by China, followed by Italy and other European countries. The premise behind this is simple: devolution has led to homogeneity of the port service, meaningless port competition and waste of scarce financial resources. However, basic infrastructure such as that of ports is there to provide the platform on which companies compete, but it ought not be the subject of competition itself. Co-opetition is thus the new port model. In this, the development of basic port infrastructure (berths, terminals, channels, breakwaters, etc.) is centrally coordinated, to maximize regional benefit. The infrastructure is then meant to be used by private (or public) companies, i.e., port service providers such as terminal operators, towage companies, pilot corporations, stevedores, and a miscellany of port-related activity, in competition among themselves. Competition here could be ‘competition in the market’ or ‘competition for the market’, the latter being the preferred model (concessions) of most ports. But, to make this point crystal clear, someone needs to be out there to veto my ego-boosting managerial decision to build a new terminal, just because my next-door neighbour is doing so, or because carriers, in possession of significant market power these days, can successfully play one (container) port against the other.-

 I am not aware of a port-city not proud of its port: the need for expansion, real or imaginary, is always on top of the agenda of every city administration, particularly during periods of local elections.

 I have described the difference between the two models in earlier communications. Competition for the market is the preferred model of the European Commission.

Why do they do this?
«But to fill the ship», they will reply.
«And why can't you fill the ship alone?» I ask, «or together with your alliance partners?»
«Because it is too big», they will say.
«And why is it so big?» I insist.
«But in order to enjoy economies of scale», they immediately retort.
«But to enjoy economies of scale», I continue, «you first must fill the ship, while you know you can't. Are you therefore building megaships as a gift to your competitor?»
In my “Gigantism in container shipping, ports and global logistics” (link below), I have proposed a pricing strategy for liner companies, leveraging on their comparative advantage, which is the ‘ship’. In short, 'charge more for the component of the supply chain where you have the comparative advantage, and less for the one where you must compete'. The overall price of the 'door-to-door' transport should remain the same. But the 3PL will have to pay more now for your ship, and this will give you the competitive edge you seek to enter 'logistics'.
Some carriers have listened; especially those controlling marine terminals. Others have not.

The competitiveness of ports has received its fair share of attention in the scientific literature, perhaps more than many other sectors of the economy. This, because the crucial role of ports as the indispensable nodes in fiercely competing global supply chains is becoming increasingly felt by policymakers.
Factors determining the competitiveness of ports are many, but their importance is weighed differently by different stakeholders. This is normal in piecemeal assessments, which often resemble the time-honored fable of the blind men trying to assess an elephant. For instance, (port) costs may not be ‘declared’ of equal importance by all stakeholders, with some of them opting for higher efficiency in port operations, or better access to foreign markets (connectivity and centrality arguments), or a better hinterland access. At the end of the day, however, everyone’s interest is to minimize their costs, may this be achieved from higher operational efficiency, access to markets or from any of the above.
In the absence of a systems approach, or structural modelling, in the literature of port competitiveness (a project we are currently working on), the ranking of paired-comparisons attempted in the full article through the Fuzzy Analytic Hierarchy Process (FAHP) methodology takes us half way to our final objective. There is another objective here, however, summarized in the paper’s implicit questions: Are the criteria used by carriers in selecting a port of call the same as those valued as important by the ports themselves? Do the two actors, shipowners and ports, understand each other well? What is the value of a better ‘understanding’? Would shipowners look at the larger picture (generalized costs), over and above their preoccupation with port efficiency? And would ports understand that their good fortune of having a prime port location should not allow them to rest on their laurels, but understand that more needs to be done to attract the ship? As said, our questions are implicit and so are their answers. But by showing that ports and carriers do not always see eye to eye, we have covered a lot of ground towards helping them to eventually start thinking alike.
