HD Hyundai Accelerates Development of SMR-Powered Vessels
▶ HHI and KSOE jointly develop an SMR-powered car carrier with Hyundai Glovis and other partners
▶ Receives AiP from LR for the vessel’s conceptual design at Posidonia 2026 in Athens, Greece
▶ Signs defense cooperation agreement with Greece’s largest shipyard and MOU with HJ Shipbuilding & Construction to adopt autonomous navigation solutions as a standard specification
HD Hyundai is accelerating the development of small modular reactor (SMR)-powered vessels by expanding its range of vessel types.
HD Hyundai Heavy Industries (HHI) and HD Korea Shipbuilding & Offshore Engineering (KSOE), the shipbuilding affiliates of HD Hyundai, said that they have received Approval in Principle (AiP) from Lloyd’s Register (LR) at Posidonia 2026 in Athens, Greece, for the conceptual design of a large Pure Car and Truck Carrier (PCTC) equipped with a Molten Salt Reactor (MSR).
In this project, jointly developed with Hyundai Glovis, G-Marine Service, and the Korea Atomic Energy Research Institute (KAERI), HD Hyundai was responsible for the vessel’s conceptual design and technical review. Hyundai Glovis contributed operational insights based on its experience operating PCTCs, while G-Marine Service conducted assessments from a ship management perspective and KAERI reviewed the application of MSR technology.
Recognized for its high level of safety and efficiency, the technology is considered well suited for maritime nuclear power applications. HD Hyundai is currently developing an MSR-powered container ship and has now expanded its development efforts to include car carriers.
An SMR-powered car carrier can maintain high power output without the need for refueling, enabling high-speed operations over long distances. The vessel also produces no carbon emissions, providing environmental benefits.
During the exhibition, HD Hyundai also received certifications from global classification societies for a range of technologies, including an industry-first LPG dual-fuel container ship currently under development and an LPG carrier equipped with a Type-B tank designed to enhance safety.
In addition, HHI signed a comprehensive memorandum of understanding (MOU) with Skaramangas Shipyards, Greece’s largest shipyard, to pursue joint participation in projects involving Greek Navy and Coast Guard vessels, as well as manned-unmanned integrated systems incorporating unmanned surface vessels (USVs).
Separately, Avikus, HD Hyundai’s autonomous navigation subsidiary, signed an MOU with HJ Shipbuilding & Construction to adopt its HiNAS Control autonomous navigation solution as a standard specification. Under the agreement, Avikus’ autonomous navigation system will be installed as a standard feature on all commercial vessels built by HJ Shipbuilding & Construction.
“HD Hyundai is showcasing its industry-leading environmentally friendly vessel technologies through collaboration with major shipping companies and classification societies,” an HD Hyundai official said. “We will continue to lead the transition to a carbon-neutral shipping industry through ongoing technology development and investment.”
Five HD Hyundai affiliates—HD Hyundai Heavy Industries, HD Hyundai Samho, HD Hyundai Marine Solution, Avikus and HD Hyundai Electric—participated in Posidonia 2026 from June 1 to June 5. The group showcased environmentally friendly vessels at a booth within the Korea Pavilion organized by the Korea Offshore & Shipbuilding Association, while also displaying energy-efficient ships and marine equipment at a dedicated HD Hyundai exhibition hall.
Celebrating its 29th edition this year, Posidonia is widely regarded as one of the world’s three leading maritime and shipbuilding exhibitions, alongside Nor-Shipping in Norway and SMM in Germany. The biennial event attracted approximately 2,000 companies from more than 130 countries.
■ Type-B Tank: An independent tank design that maximizes structural reliability through advanced structural analysis, enabling it to achieve a high level of safety without the need for a full secondary barrier, unlike a Type-A tank.
