Evergreen: Taiwan’s Evergreen, the world’s sixth-largest carrier (it was seventh largest in 2020), grew capacity by 30% or 385,297 TEUs during the super-cycle period. Virtually all of that growth came in 2021-22.
“Evergreen last year took no fewer than 20 new buildings,” wrote Alphaliner. In 2021, Evergreen’s growth was also driven by new builds, with 14 new vessels entering service.

Zim: While several lines grew due to new builds ordered pre-pandemic, others specifically increased capacity to take advantage of the booming freight market. One was MSC, which grew predominantly by buying second-hand ships. Another was Israel’s Zim (NYSE: ZIM), the 10th-largest carrier, which used a different strategy: chartering tonnage.
According to the Alphaliner data, Zim’s capacity surged by 241,520 TEUs or 83% between Jan. 1, 2020, and Jan. 1, 2023, making it the second-fastest grower in percentage terms after HMM.
It increased capacity by 29% last year, the highest percentage gain of 2022 among the top 10.
According to Alphaliner, Zim was “particularly active in the charter market, since ending its cooperation with the 2M partners [Maersk and MSC] on the Asia-Med and Asia-West Coast North America routes meant [it] needed some extra tonnage to maintain a strong presence in these trades.”
The moderate gainers — and the losers
The other five carriers in the top 10 have either grown moderately during the COVID era or dropped capacity.
Hapag-Lloyd and Yang Ming: Germany’s Hapag-Lloyd, the fifth-largest liner operator, increased capacity by 1.8% last year and by 64,800 TEUs or 4% over the past three years.
At No. 9, Taiwan’s Yang Ming upped capacity by 60,724 TEUs or 9% since pre-pandemic. It was the eighth-largest carrier in early 2020.
Maersk: Denmark’s Maersk, the world’s second-largest carrier, has kept capacity effectively flat over the past three years (up 0.6%). Maersk had long been the largest liner operator in the world until it was usurped by MSC a year ago.
“Our strategy is not to gain market share in the ocean [shipping],” former Maersk CEO said on the company’s latest conference call. “We’re not really defining ourselves anymore in terms of ocean volumes. Our strategy is to gain a share of our customers’ wallet of logistics spend.”
Maersk’s capacity fell 61,705 TEUs or 1.4% last year.
“The company had to redeliver a significant amount of chartered tonnage,” said Alphaliner. “These ships were either sold second-hand or fixed to rival carriers, which were prepared to pay higher charter rates or accept longer charter periods.”
ONE and Cosco: Japan’s Ocean Network Express (ONE), the world’s seventh-largest carrier — down from sixth pre-pandemic — reduced capacity by 0.8% last year, according to Alphaliner. Since January 2020, ONE’s capacity has fallen by 52,447 TEUs or 3%, the second-largest TEU fall among the top 10.
The carrier with the biggest TEU drop over the past three years was China’s state-owned Cosco, shedding 66,171 TEUs or 2%. It’s now the fourth-largest liner operator, pushed from the third-place slot by CMA CGM in 2021.
“The Cosco Group, including OOCL, is an interesting case since the Chinese carrier’s fleet has shrunk for the second year in a row,” Alphaliner said. “After having reduced capacity by 3.2% in 2021, the Chinese group last year saw another 2.1% decline in operated capacity.”
Newbuilds en route for top 10 lines
Changes in operating fleet size during the COVID era are only part of the story. Another is the order book. Ocean carriers used profits from the consumer boom to contract a massive wave of new ships for delivery in 2023 and beyond.
MSC has by far the largest order book, with more than double the capacity under construction of any other carrier group. According to the latest data from Alphaliner, MSC has 1.73 million TEUs on order, equating to 38% of its on-the-water fleet.
Cosco has the second-most tonnage on order (884,272 TEUs), followed by CMA CGM (689,257 TEUs).
In terms of the order book-to-fleet ratio, Zim leads the pack, with 378,034 TEUs on order, equating to 71% of its on-the-water capacity.

In aggregate, the top 10 liner operators have 5.5 million TEUs on order equating to 25% of their existing operating capacity.
Current cargo demand projections do not support the fleet growth implied by these many orders. Rather, the new deliveries, whether owned or chartered, would to a certain extent replace existing vessels in the fleet. Carriers could sell or scrap currently owned ships and/or let existing charters expire to make room for the more cost-efficient new builds.
Zim CFO pointed out on his company’s latest conference call that existing charters are “bridging our current operating capacity to the scheduled delivery of chartered newbuild vessels.” He noted that Zim has 62 chartered vessels up for renewal during the period when it will take delivery of 46 chartered new builds.
“There are a lot of options for us to entertain as we take delivery of those ships,” Zim said.
