Ocean container shipping plays a vital role in global trade, enabling the transportation of goods across vast distances. Over the years, container ships have undergone significant transformations, with advancements in technology and design pushing the boundaries of size and capacity. In this article, we delve into the evolution of ocean container ships, exploring record-breaking vessels and the challenges they present to ports and infrastructure. ocean container ship

The Rise of Very Large Container Ships (VLCs)

In recent years, we’ve witnessed a remarkable increase in the size and capacity of container ships. Taiwan-based Evergreen Marine made headlines in June when they launched the Ever Alot, the largest container ship ever built. With a capacity of 24,004 twenty-foot equivalent units (TEUs), it surpassed its slightly older sibling, the Ever Ace, which held the previous record at 23,992 TEUs[^1^].

The Ever Alot measures over 1,300 feet in length and 203 feet in width, towering over iconic structures like the Empire State Building[^1^]. These colossal vessels belong to a class known as very large container ships (VLCs) or ultra large container vessels (ULCVs). However, their size poses challenges when navigating through the locks of the Panama Canal[^1^].

Benefits and Challenges of Ultra Large Container Ships

The construction of larger container ships like the Ever Alot and Ever Ace aims to achieve economies of scale and lower container slot costs, allowing carriers to offer more competitive rates to shippers[^1^]. Since 2012, the average capacity of container ships has grown from less than 3,000 TEUs to around 4,500 TEUs[^1^]. In the last decade alone, over 50 ships with a capacity of 21,000 TEUs or more have been built[^1^].

While these massive vessels provide cost advantages, they also present significant challenges. Matt Stoller, the director of research at the American Economic Liberties Project, raises concerns about the financial sustainability of such large ships. Ports need to invest in larger facilities, increased dredging, new warehouses, additional cranes, and personnel to handle these behemoths[^1^]. Furthermore, road infrastructure may need to be upgraded to accommodate the increased volume of cargo moving to and from ports[^1^].

The Port Implications and Global Reach

The size limitations of many ports worldwide, particularly in the United States, restrict the deployment of ultra large container ships. Stoller points out that while the U.S. has numerous ports, most are not equipped to handle these massive vessels[^1^].

Despite these limitations, some large container ships have made appearances at U.S. ports in recent years. In 2015, the 18,000-TEU CMA CGM Benjamin Franklin made history by calling at the Port of Los Angeles, becoming the largest container ship to visit a North American port[^1^]. The record was broken in 2020 when the MSC Anna, a 19,200-TEU ship, docked at the Port of Oakland in California[^1^]. On the U.S. East Coast, the CMA CGM Marco Polo, a 16,022-TEU vessel, called at several ports in 2021, including New York, New Jersey, Savannah, and Charleston[^1^].

The Constant Push for Larger Ships

The race for size supremacy in the container ship industry continues to drive innovation and shipbuilding. While the Ever Alot held the title of the largest container ship when it launched in August, it may have already been surpassed by newer vessels. On October 29, the Yangzijiang Shipbuilding Group in China unveiled two forthcoming ships for the Mediterranean Shipping Company (MSC), the world’s largest shipping line[^1^]. The MSC Loreto and MSC Irina, each with a container capacity of 24,636 TEUs, are set to become the new record holders[^1^].

MSC, which overtook Maersk as the world’s largest ocean carrier in January, continues to expand its fleet aggressively[^1^]. With a newbuild order book of 1,482,178 TEUs, MSC demonstrates its commitment to growth and maintaining its leading position in the industry[^1^].


The evolution of ocean container ships has seen remarkable achievements, with vessels like the Ever Alot and Ever Ace breaking capacity records. While these giant ships offer cost advantages through economies of scale, they also present challenges to ports and infrastructure. The need for larger facilities, increased dredging, and upgraded road networks underscores the complexities of accommodating these behemoths. Nevertheless, the quest for larger ships continues, with MSC poised to introduce even larger vessels into its fleet.

As the global shipping industry evolves, we can expect further advancements in container ship design and technology. The race for size supremacy will likely continue, driving innovation and pushing the boundaries of what is possible in ocean container shipping.
