Solving Empty Container Repositioning Problem with AI


Solving Empty Container Repositioning Problem with AI

Container shipping transports 80% of all manufactured goods around the world. It is the industry that underpins the global economy – the quantity of goods carried by containers has risen from around 102 million metric tons in 1980 to about 1.83 billion metric tons in 2017. In December 2019, the combined TEU capacity of all the container vessels in the world has surpassed 23 million and this number is expected to grow by 3.5% on average every upcoming year.

Every 1 in 3 containers globally is moved empty, and according to Boston Consulting Group (BCG) it costs the industry up to $20 billion per year.

However, the shipping industry still suffers from huge inefficiencies. Namely, empty container repositioning represents a significant problem — according to the Boston Consulting Group (BCG), one out of three containers is shipped empty. It sums up to a total of nearly 60 million empty container moves per year at an annual cost of $20 billion to the industry — up to 8% of a shipping line’s operating costs. The problem majorly influenced by trade imbalances as well as long relocation time, high costs related to safety stock, and unreliable commercial forecasts, which are mainly based on the gut feeling of planners and local managers.

Furthermore, there are extra costs associated with storing and maintaining these empty containers, meaning the total cost of empty logistics is estimated by Transmetrics to be more than 12% of operating costs.

In the following article, we will take a look at the major industry trends, what exactly influences the problem of empty container repositioning, and how container shipping companies can solve this problem with the help of digital technologies.

Container Shipping Market Outlook

2020 has brought new challenges for the container shipping sector. In addition to the existing trade imbalances, the COVID-19 pandemic has negatively affected the industry, creating new port and travel restrictions for shipping firms to contend with. All of this decreases profitability and puts additional pressure on operations, forcing shipping companies to make tough decisions such as letting go of some of their employees or cutting down trade lanes. Considering these things, the issue of empty container repositioning is more distressing than ever.

After industry-wide profitability in 2017, the container shipping market outlook was not as positive. Seeking economies of scale and lower unit costs, carriers deployed bigger and bigger ships, already with capacities of over 21,000 TEU(twenty-foot equivalent units). As a result, the world’s fleet capacity continued growing too fast for the demand to cope with it. In addition to the overcapacity issue, the prices for transporting goods have declined. The consolidation wave in the industry over the last few years has created a situation on the market, where the top five carriers managed almost two-thirds of global capacity.

Two other major topics affected the container shipping industry in 2018: the trade tensions between the U.S. and China, the world’s two largest economies, and the Global Sulphur Cap regulation by IMO (International Maritime Organization). The new trade tariffs affected $34 billion worth of Chinese products imported into the U.S., with China taking countermeasures on U.S. imports. At the same time, carriers had to start preparing for the global 0.5% Sulphur cap, which would be introduced in 2020 and would affect up to 70,000 ships, according to IMO estimates. This regulation could lead to a 20-30% increase in total fuel costs, which would ultimately be passed on to customers. Slowing growth of global world trade volumes and an escalating trade war were expected to continue negatively influencing the container shipping demand in 2019, so cost-cutting has become critical for the container shipping industry.

Main Reasons for Inefficiencies in Empty Container Repositioning

Repositioning of empty containers in the shipping industry represents about 5% to 8% of a shipping line’s operating costs. Further, there are additional costs for storage of empty containers and their maintenance, so the total cost of empty logistics is estimated by Transmetrics to be more than 12% of operating costs.

This industry-wide problem has many aspects to it:

  • Trade Imbalances – By far, the main reason for empty container repositioning arises from trade imbalances, where full containers are shipped from export-oriented locations (e.g. Asia), and typically, many of them have to be relocated back empty from import-oriented destinations (e.g. Africa). Roughly, such economic imbalances affect two-thirds of all movements of empty containers.
  • Relocation Time – To make it even worse, relocating containers takes several weeks, sometimes months. That is why shipping lines need to understand their demand weeks in advance, relocate containers across their network and maintain safety stocks of empty containers in various locations all over the world – all while trying to lower overall capacity and minimize storage and relocations costs. For example, when carriers want to build up their stock of containers in Asia before the Chinese New Year, then they already have to start relocating containers to Asia in November-December.
  • Empty Stock and Its Costs – In order to meet the demand, companies have to decide how many empty containers of each type to keep in each location. There are three main types of costs related to empty stock – repositioning costs, storage costs and costs of ownership. Since moving empty containers uses the capacity of the same ships that move full containers, the repositioning costs for both types are relatively the same. Storage costs depend on complicated contracts with each depot where containers are kept. Typically companies have some free tier, after which they pay different rates depending on the number of containers and/or days. Last but not least, the more containers you want to have in an empty reserve, the more containers you need to have in total, which comes with a cost of ownership of about $0.5-1 per TEU per day for normal dry containers and potentially much more for specialty containers (e.g., reefers, chemical tanks and others).
  • Unreliable Commercial Forecasts – Typically, commercial people in the industry are notorious for over-forecasting, and many forecasts are coming from different agents and are based on their gut feeling. Furthermore, there are huge fluctuations in seasonal demand for shipping containers. As a result, the low accuracy of commercial forecasts makes them unhelpful for planning purposes.

In addition, there are two other very important aspects that are applicable to many container shipping lines:

  • Using Excel for Planning – Even nowadays, complex decisions for planning empty container logistics are based on the experience of logistics teams and are typically handled manually with Excel, which until today remains one of the most widely used supply chain management tools. Such manual and time-consuming planning is still possible since the majority of the container shipping lines own too many containers in reserve, which leads to significant cost inefficiencies.
  • No Clear Visibility on the Costs – In many cases, the logistics team manages empty container repositioning globally, while a procurement team controls vendor costs. With different types of costs in place, that can lead to situations in which container shipping lines know the total amount they paid to a certain vendor in a certain location, but the drivers behind these costs are not clear – for example, how many containers were moved, why were they moved, where were they going, was it necessary to move them, if another vendor could do it, and so on. Thus, people making logistics decisions do not always have a full awareness of the cost impact of their recommendations.

Technologies That Can Solve Empty Repositioning

Luckily, with the advancements of modern technologies, it became possible to tackle the problem of empty container repositioning and optimize day-to-day operations. With the right tools, logistics companies can yield far-reaching business benefits and cost savings without any negative impact on customer service levels. These technologies should closely complement operational expertise in order to ensure that the right equipment is always available at the right location at the right time.

Logistics companies will always need to move empty containers from import-oriented to export-oriented locations and there is not much that can be done about it. There is no way to eliminate the entire $20 billion cost of empty container repositioning, but it is estimated that about 30% of this cost is caused by inefficiencies and can be saved with technologies.

All of the solutions that are mentioned in the article have already proved their potential to improve empty container repositioning. However, transport companies need to keep in mind that any optimization technology by itself is only a part of the solution to achieve real cost savings in logistics. Companies need to integrate the technologies within the business processes of relevant departments so that their logistics professionals can quickly receive and review software results and are able to execute decisions based on the software’s suggestions.

Empty container repositioning is just one of the major problems that the maritime shipping industry faces. That led to the creation of multiple maritime logistics startups, which are using innovative tools like digital platforms, predictive analytics, fuel efficiency solutions and more to help logistics companies optimize their operations and cut costs.
