HD KSOE unveils ABS-approved nuclear-powered containership model

South Korean shipbuilding major HD Korea Shipbuilding & Offshore Engineering (KSOE) has rolled out a nuclear-powered containership model utilizing small modular reactor (SMR) technology to accelerate the development of nuclear-powered vessels.

HD KSOE revealed its nuclear-powered ship design model for the first time on February 12, 2025, in Houston, USA.

The newly introduced model builds on the 15,000 TEU containership design applying SMR technology which had previously received approval in principle from the American Bureau of Shipping (ABS).

According to the shipbuilder, the new design model features enhanced economic efficiency and safety by incorporating actual equipment and safety design concepts.

HD KSOE said it had optimized the space previously occupied by large engine room equipment to accommodate additional containers, enhancing economic efficiency. The company also applied a marine radiation shielding system using a double-tank method with stainless steel and light water to ensure safety.

Furthermore, in collaboration with energy technology company Baker Hughes, HD KSOE applied a supercritical carbon dioxide-based propulsion system, improving thermal efficiency by approximately 5% compared to existing steam-based
