China-Built 400m LNG Mega Ship Transits Yangtze Bridge

A 399.9-Meter Test of Precision Beneath the Yangtze

One of the world's largest container ships threaded its way beneath the Yangtze River bridge in eastern China this week, a transit that demanded millimetric precision from both the vessel and the river pilots guiding it. The CMA CGM Orsay, a 399.9-meter liquefied natural gas (LNG) dual-fuel ultra-large container vessel, cleared the crossing as it moved downriver after delivery, CGTN footage showed.

The ship is the third in a series of ten 24,000-TEU (twenty-foot equivalent unit) mega-ships that France's CMA CGM Group ordered from China's Yangzijiang Shipbuilding in June 2023, with each newbuilding priced at about US$240 million and delivery scheduled between 2026 and 2027. Its passage under the bridge, a span that leaves little margin for error beneath a hull of this size, highlights both the scale of modern container shipping and the growing capability of China's private yards to build it.

The Orsay and a Ten-Ship Order That Reshaped a Fleet

Built at Jiangsu Yangzi Xinfu Shipbuilding, a unit of Yangzijiang, the Orsay joins a series that is redrawing CMA CGM's flagship fleet. The first vessel, CMA CGM Notre Dame, was delivered in May 2026 with a carrying capacity of 24,212 TEU and made a maiden call at Shanghai, becoming the first of the ten ships to enter service. The second, CMA CGM Pantheon, was handed over on July 21 and departed the yard on July 25, according to a Yangzijiang statement.

The Orsay shares the class's defining dimensions: an overall length of 399.9 meters, a beam of 61.3 meters, and a deadweight tonnage above 231,000 tons, figures that place the vessels among the largest container ships afloat. When all ten units are delivered, the series will add more than 200,000 TEU of capacity to CMA CGM's operated fleet, a meaningful expansion for a carrier that ranks among the world's top three liner operators by capacity.

China's Private Yards Enter the ULCS Club

The order has significance beyond the French flag it will fly. Yangzijiang, listed in Singapore and based in Jiangsu, is the first privately owned Chinese shipbuilder to construct 24,000-TEU dual-fuel container ships, a segment long dominated by state-linked giants such as China State Shipbuilding Corporation's Hudong-Zhonghua yard. Hudong-Zhonghua previously delivered 24,000-TEU LNG dual-fuel ships to CMA CGM, including the CMA CGM Seine in April 2025 and the CMA CGM Grand Palais in March 2026, seven and a half months ahead of schedule.

The Yangzijiang series therefore signals a broadening of China's shipbuilding capacity. Where ultra-large container vessels (ULCS) were once concentrated in a handful of yards, the entry of a private builder with two deliveries completed and an eight-ship pipeline demonstrates that the technology and project management for this vessel class have matured across China's shipbuilding sector. For global liner operators, that means more yards capable of building the largest ships, and more leverage in pricing and delivery terms.

The commercial stakes are substantial. The ten-vessel program, valued at roughly US$2.4 billion at the 2023 contract price, is among the largest single container-ship orders placed by a European carrier in recent years. Delivery schedules spanning 2026 and 2027 give CMA CGM a rolling stream of new tonnage just as the industry braces for a wave of capacity additions from earlier ordering cycles, a factor analysts are already weighing against freight-rate forecasts for the Asia-Europe trade.

LNG Dual-Fuel: Shipping's Transition Fuel

The ten ships are powered by LNG-capable dual-fuel engines, a configuration that allows them to burn either LNG or conventional marine fuel. CMA CGM has positioned LNG as the bridge fuel for its fleet's decarbonization, citing reductions in carbon dioxide emissions and significant decreases in atmospheric pollutants such as sulfur oxides and particulate matter compared with heavy fuel oil.

The choice carries geopolitical and commercial weight in the Asia Pacific. LNG bunkering infrastructure has expanded steadily across the region, with major hubs in Singapore, Shanghai, and Japan's ports supporting vessels that can switch fuels on long-haul routes between Asia and Europe. The CMA CGM series, deployed on the Asia-Europe and trans-Pacific trades where emissions scrutiny is highest, will test whether LNG dual-fuel propulsion can hold up commercially as methanol and ammonia propulsion gain ground in newbuilding orders.

The French Flag and a Strategy of Maritime Sovereignty

All ten vessels will fly the French flag and be registered under the French International Register, a decision announced by CMA CGM Chairman and CEO Rodolphe Saadé in late 2025. The move was framed in Paris as part of France's maritime sovereignty strategy, with the company committing to recruit 135 French seafarers and to strengthen its partnership with the French Maritime Academy (ENSM).

For Japan and other Asian shipping nations, the French-flag decision is a reminder that ownership and operation of ultra-large vessels is increasingly tied to national industrial policy, not just commercial calculation. It also underscores how Chinese shipbuilding, which accounted for the majority of global newbuild tonnage in recent years, has become the production base of choice even for carriers pursuing European flagging and European labor commitments.

Implications for Japan and the Asia Pacific

The milestone reverberates in Japan, where shipbuilders compete in the same ULCS segment. Ocean Network Express (ONE), the Japanese liner alliance of NYK, MOL, and K Line, took delivery of its first 24,000-TEU "Megamax" vessel, the ONE Innovation, from Imabari Shipbuilding in June 2023, and has since chartered additional 24,000-TEU newbuilds from Japanese shipowners including Shoei Kisen Kaisha.

Japanese yards retain strengths in specialized tonnage, LNG carriers, and high-value-added vessel types, and Japan remains a leading supplier of marine equipment and technology. But the Yangzijiang deliveries show how quickly Chinese private yards have closed the gap in the largest and most complex container ship segment. For Japanese shipbuilders, the competitive question is whether to match Chinese scale in ULCS construction or to deepen specialization in the gas carrier and advanced-propulsion niches where margins remain stronger.

The timing is also sensitive for the region's liner operators. With ONE, Hapag-Lloyd, and other carriers all renewing fleets in the 24,000-TEU class, the availability of Chinese private yard capacity shortens the lead times that once favored Korean and Japanese builders. For shippers in Japan, the practical effect is visible in service reliability and freight economics: larger, more fuel-efficient vessels on the Asia-Europe lane tend to pressure unit costs, a trend that the ten-ship CMA CGM program is set to reinforce as each new unit enters service.

What to Watch For

The remaining seven vessels in the ten-ship series are due for delivery through 2027, with each handover expected to be accompanied by a similar downriver transit. Shipping analysts will watch the deployment of the class, the performance of its LNG dual-fuel engines on long-haul routes, and whether CMA CGM's French-flag strategy prompts rival carriers to pursue their own flagging arrangements.

For the Asia Pacific, the series is a concrete measure of how deeply China's private sector now participates in the world's most demanding shipbuilding segment, and of how quickly the region's largest carriers are renewing their fleets with lower-emission tonnage. The Orsay's passage beneath the Yangtze bridge was a single maneuver, but it carried the weight of a broader industrial shift that will shape container shipping for the rest of the decade.
