Although ports have adopted automation more slowly than comparable sectors, notably mining and warehousing, the pace is now starting to accelerate. Automated ports are safer than conventional ones. The number of human-related disruptions falls, and performance becomes more predictable. Yet the up-front capital expenditures are quite high, and the operational challenges—a shortage of capabilities, poor data, siloed operations, and difficulty handling exceptions—are very significant. A McKinsey survey indicates that while operating expenses decline, so does productivity, and the returns on invested capital are currently lower than the industry norm.
Nonetheless, successful automated ports show that careful planning and management can surmount these difficulties: operating expenses could fall by 25 to 55 percent and productivity could rise by 10 to 35 percent. And in the long run, these investments will lead the way toward a new paradigm—call it Port 4.0—the shift from asset operator to service orchestrator, part of a larger transition to Industry 4.0, or digitally enabled efficiency gains throughout the world economy. Port 4.0 will generate more value for port operators, suppliers, and customers alike, but that value isn’t proportionally distributed across ports and their ecosystems. Innovative business models and forms of collaboration will be required to realize this vision.
The difficult economics of port automation
The first automated container port was developed in Europe in the early 1990s. Since then, many ports—more than 20 in the past six years—have installed equipment to automate at least some of the processes in their terminals (see sidebar, “What is port automation?”). Almost 40 partly or fully automated ports now do business in various parts of the world, and the best estimates suggest that at least $10 billion has been invested in such projects.1 The momentum will probably accelerate: an additional $10 billion to $15 billion is expected over the next five years.
On the face of it, container ports seem ideal places to automate. The physical environment is structured and predictable. Many activities are repetitive and straightforward. They generate vast amounts of readily collected and processed data.2 Better still, the value from automation includes not only cost savings but also performance and safety gains for ports and the companies that do business there.
Nonetheless, ports are moving more slowly than sectors with comparable complexities (Exhibit 1), in part because the economics of automating them haven’t lived up to expectations. In the mining sector, which is also process driven and asset intensive, some early movers in automation have improved costs and productivity by 20 to 40 percent. In the warehousing business, the improvements have been estimated at 10 to 30 percent. Manufacturers of cars and trucks have also successfully automated complex processes, and some of the equipment they use, such as automated guided vehicles and materials-handling robots, are highly relevant for ports.
Yet our recent survey of industry leaders indicates that the real-world performance of most automated ports doesn’t increase sufficiently in every material way. Safety improves, the number of human-related disruptions (such as shift changes) falls significantly, and performance becomes more predictable. But practitioners responding to the survey think that these ports, especially fully automated ones, are generally less productive than their conventional counterparts. The return on invested capital of assets at some automated ports is falling short by up to one percentage point from the industry norm of about 8 percent.
What the research shows
To determine the current status and future outlook of container-terminal automation in the port sector, McKinsey hosted a forum together with the Shanghai International Port Group and conducted a survey in 2017, just before the Port of Shanghai rolled out a fully automated terminal. We collected the responses of more than 40 participants from leading practitioners in the top ports of China, Europe, the Middle East, Singapore, and the United States; global suppliers of automation equipment and software; and experts from academia, port asset-management firms, and shipping companies. More than three-quarters of the participants were senior executives or high-level managers.
The survey clearly showed that automation has become a trend. Eighty percent of the respondents expect that in the next five years, at least half of all greenfield port projects will be semi- or fully automated. Thirty-five percent believe that the proportion of automated ports will rise above seven in ten.3 Brownfield projects—the total or partial conversion of existing conventional ports—will probably gain momentum soon: more than half of the participants expect at least 50 percent of the top 50 ports to initiate retrofitting plans or to add automated equipment during the next five years.
But the survey also clearly showed that the return on investment from port automation demands attention from port operators and investors alike. Up-front capital outlays are high. We estimate that to justify these investments, the operating expenses of an automated greenfield terminal would have to be 25 percent lower than those of a conventional one or productivity would have to rise by 30 percent while operating expenses fell by 10 percent.4
The respondents to McKinsey’s survey expect automation to cut operating expenses by 25 to 55 percent and to raise productivity by 10 to 35 percent, in line with our estimates of what might be possible. But today these expectations generally aren’t realized, especially in fully automated projects.5 Our survey indicates that operating expenses at automated ports do indeed fall, but only by 15 to 35 percent (Exhibit 2). Worse, productivity actually falls, by 7 to 15 percent. An executive of a global port operator told us, for example, that at fully automated terminals, the average number of gross moves per hour for quay cranes—a key indicator of productivity—is in the low 20s. At many conventional terminals, it is in the high 30s. With numbers like these, automation can’t overcome the burden of the up-front capital expenditures.
Barriers and solutions
Responses to our survey suggest that the major barriers (in descending order of importance) are capabilities, data quality, siloed operations, and the handling of exceptions.
A shortage of capabilities
Respondents who had previous experience with automation say that the top problem is filling the specialized technical positions it requires (Exhibit 3); they add that even experienced engineers can take as long as five years to train. Many ports have apparently underestimated the challenge of acquiring the needed capabilities, especially in planning and implementation. Port and terminal operators must therefore step up their efforts to acquire talent and build these capabilities.
Poor data quality
Like organizations in other sectors, ports find that data silos and a lack of data standards are basic problems in automation. Many interviews with managers of port operations indicate clearly that the quality of data and the data analytics isn’t sufficiently strong to run automated ports efficiently.
Why? The first reason is that the lack of a structured, transparent data pool makes it hard to monitor and diagnose the operations and performance of equipment quickly. Second, the standards, formats, and structures of the data may be misaligned or even wholly absent, so ports can’t collect and exchange data efficiently.
Data-infrastructure applications have huge potential. They can help to predict and forecast demand and the arrival-and-departure patterns of container ships. They can schedule the maintenance of equipment for optimal availability, allocate equipment and frontline staff, and adjust the allocation in real time. They can also use machine intelligence to make plans ever more accurate. Standardizing data so that they can be used in these ways will help to make ports and terminals more efficient. Ports are not only becoming more aware of this reality but are also starting to upgrade and harmonize their terminal operating systems. Nonetheless, the IT setups of most terminal operators remain fragmented.
Breaking down silos between functions is always a challenge, but it is especially difficult for ports: the basic principle of automation is process orientation, which requires integration across the end-to-end terminal process chain and important interfaces. Automated ports, unlike conventional ones, can’t contain problems at individual functions or process steps. They must therefore ensure close collaboration among activities ranging from marine operations to crane movements to the control of yards and gates.
Many ports find that exceptions are the greatest single challenge for raising productivity. More than 60 percent of the operators in our survey agree that when ports have large numbers of exceptions, the likely culprit is a mistaken approach to automating manual processes. Such ports skip an important step: simplifying processes before automating them. These processes therefore remain cumbersome even after they are configured by automated systems.
The way forward
No one route will take all ports to the automated future, but our knowledge of the leading automated ports has revealed general principles that others might consider.
- Build automation-ready capabilities. As we have already noted, port automation shouldn’t merely run old processes with new automated equipment. The first step is to redesign the operating model. Port operators should start with a blank slate as they think through every process from beginning to end, across functional silos. The redesigned processes will suggest the necessary organizational structure and capabilities, including data, the human–machine interface, and the technical infrastructure.
Set up a strong project-governance and communication plan—and execute with discipline. Automation projects require a wide variety of capabilities in areas such as terminal operations, technical engineering, software engineering, and systems integration. A collaborative project environment is essential, and so is early input from stakeholders such as customers, shareholders, labor representatives, operations leaders, the technical team, vendors, and external experts.
Make sure to leave enough time for testing, dry runs of operations, and production trials. A normal project cycle could involve 3,000 to 5,000 incident logs that users of the terminal and the port must handle collectively, as well as months of stabilization efforts. Throughout the journey, the case for change should be communicated thoroughly, and stakeholders must be carefully managed. Remember too that the capital intensity of port automation has implications for the economics of projects and for the ongoing cost of implementation, maintenance, and operations. It therefore calls for an awareness of the total cost of ownership and for disciplined execution.
- Define a road map to realize value from automation. Port concessions have timelines, so realizing the benefits of automation at a reasonable pace is important. Port executives should develop the business case for investments and support it with solid productivity, cost, and implementation targets. Then they should monitor performance to track the capture of value. A step-by-step approach will probably work better than a “big bang” push for a total transformation in one mighty blow.
- Build and continually refresh your technology ecosystem. Technical functions not only support automated ports but also control the effort to improve their productivity and asset turnarounds. An appropriate portfolio of in-house and third-party technology providers balances strategic control of important competitive advantages against the need to keep up with the latest developments. The choice of technologies should reflect the business needs of the port and its customers, not the intellectual curiosity of the technical staff.
- Incorporate external data into your automation system. One key benefit of automation is consistent, predictable performance. In a perfect world, machines would execute nothing except instructions. But operational variables beyond terminals—for instance, the arrival of trucks, feeders, and ships—are also important elements of performance; ships, for example, may arrive or depart significantly earlier or later than planned. An advanced automated port should factor these variables (typically available through external data) into its automation systems so it can be flexible enough to cope with changes from customers and unlock the potential of its investment in automation.
Beyond automated machinery
Over the years, ports have evolved through several basic models of operation. In what we call Port 1.0 (“management by hero”), they adopt individual pieces of machinery, such as yard cranes, while workers link individual process steps and direct yard operations. The process-driven operations that define Port 2.0 (“management by process”) demand a process-oriented approach: ports govern the steps of these processes through a terminal operating system, while operators make most decisions in the central control tower. Port 3.0 (“management by exception”) is a progression from Port 2.0: automated equipment and algorithms run and optimize processes, leaving humans to dispose of exceptions.
But Port 3.0 isn’t the end of the story. In the model of the future, Port 4.0 (“from manage to orchestrate”), ports will enlarge their role by orchestrating physical and information flows inside and outside terminals to enhance the port ecosystem’s broader, systemwide efficiency (Exhibit 4). Forward-looking ports will push toward this next horizon, beyond automation, in the coming Port 4.0 era. Every player—terminal operators, trucking companies, railroads, shippers, logistics companies, and freight forwarders—will be connected to optimize not just the port itself but also its entire ecosystem.
The cornerstone of Port 4.0 will be automation, which—if implemented and configured appropriately—can transform ports into highly reliable and flexible logistics hubs that direct predictable physical flows and use extensive data and advanced analytics to buffer the many variables in transportation networks. Ports, now often seen as constraints in transportation networks, could then actively resolve problems in other parts of the value chain.
This journey from Port 1.0 to Port 3.0 has been evolutionary, but Port 4.0 requires a leap into the future and bold changes in the operating model. We estimate that for a six- to eight-million TEU6 port that handles both imports and exports, the value at stake from Port 4.0 might be more than $1.5 billion a year for the port community, including terminal operators, shipping companies, intermodal operators, freight forwarders, shippers, and consignees. Terminal operators might capture less than 20 percent of the value pool directly, and other parties in the ecosystem would claim the rest (Exhibit 5).
The sectorwide gain in efficiency is obvious. But the ports’ traditional investment model, which requires terminal operators to front-load investments, doesn’t align with the distribution of value in Port 4.0. It will be essential to involve the relevant stakeholders and to develop, together with them, a new business and governance model for collaboration—a model that ties investments to the redistribution of value. Only then will Port 4.0 unlock its full potential.
The value at stake from Port 4.0 is large but not proportionally distributed across ports and their ecosystems. Realizing that value will require innovative business models and new collaboration frameworks. They won’t come easily. Yet this is surely a future worth striving for.
