HD Hyundai partners with American Bureau of Shipping to advance the conceptual design of a nuclear-powered container ship using small modular reactor technology.
On March 9, South Korean shipbuilding giant HD Hyundai announced it had signed a joint development agreement with American Bureau of Shipping to advance the conceptual design of nuclear-linked electric propulsion systems for large container ship s.
The collaboration marks a major step toward building what could become the world’s first nuclear-powered container vessel designed for commercial shipping.The agreement was signed recently at the company’s Global R&D Center in Bundang, Gyeonggi Province, South Korea. Under the partnership, the organizations will develop a conceptual design for a 16,000-TEU container ship powered by nuclear-linked electric propulsion. A ship of this size can transport tens of thousands of cargo containers across global trade routes. The companies aim to explore whether nuclear energy can provide a reliable and efficient power source for long-distance maritime transport.Designing propulsion for next-generation cargo shipsThe joint project focuses on several engineering areas needed for a nuclear-powered vessel. These include the basic design of electric propulsion systems linked to nuclear energy, the selection of electrical equipment, and the layout of major onboard power systems.A key part of the concept involves using Small Modular Reactor technology as the ship’s main energy source. These compact nuclear reactors can produce up to about 100 megawatts of power. Their smaller size and modular construction make them easier to integrate into new applications compared with traditional nuclear reactors.Engineers from both organizations will examine how such reactors could support the high energy demand of container ships traveling long ocean routes at high speeds. If successful, the concept could develop a new propulsion system that eliminates the need for conventional fossil-fuel engines.Classification societies such as ABS play an important role in this process. These independent organizations evaluate ship designs and certify that vessels meet international safety and performance standards before they operate at sea.Improving power management and ship performanceHD Hyundai plans to design a specialized power management system tailored for large container ships using nuclear-linked electric propulsion. Such ships require steady energy supplies to maintain high cruising speeds while powering numerous onboard systems.The concept also includes a twin-screw propeller configuration. In this setup, two propellers operate simultaneously, improving thrust and maneuverability for massive cargo vessels navigating ports and narrow channels.Another key feature is a direct-drive propulsion method that connects the electric motor directly to the propeller. This approach reduces mechanical energy losses that normally occur during power transmission. Engineers believe the system could improve overall efficiency while reducing energy waste during operation.The design may also allow more refrigerated containers, commonly known as reefer units, to be carried onboard. These containers transport frozen and chilled goods and require substantial electrical power to maintain the required temperatures. With a high, stable energy supply, the ship could support a larger number of these power-hungry containers, giving operators greater flexibility to handle cargo demand.Strengthening safety and regulatory complianceSafety remains one of the most critical issues when considering nuclear technology for commercial shipping. The development effort includes strengthened safety standards built directly into the ship design.Engineers plan to develop systems capable of maintaining safe operations even during extreme conditions such as collisions or flooding. Power systems will also be designed to comply with global regulations issued by the International Maritime Organization and nuclear safety guidelines issued by the International Atomic Energy Agency.“This collaboration is a very important project to verify the applicability of nuclear-powered electric propulsion systems to large container ships,” stated Matthew Muller, ABS Commercial Director for Far East Asia.“By combining HD Hyundai’s excellent shipbuilding technology and ABS’s engineering expertise in maritime safety, we will comprehensively verify the safety, efficiency, and eco-friendliness of next-generation propulsion solutions.”“Nuclear-linked electric propulsion vessels represent a highly groundbreaking and advanced technology for achieving net zero,” Shim Hak-moo, Head of the Design Division at HD Hyundai Samho, added.“In the fierce competition to gain a foothold in the eco-friendly ship market, this could become a powerful weapon for HD Hyundai.”HD Hyundai first introduced its nuclear-powered container ship concept at the Houston Maritime Nuclear Summit in February last year. Later that year, the company received Approval in Principle from ABS for its propulsion concept at Gastech 2026, signaling growing momentum for nuclear-powered commercial shipping.
