Hyundai’s Nuclear-Powered Container Carrier: The Next Big Leap for Maritime Engineering
Bychiefengineerslog 22 August 202522 August 2025
The maritime industry is poised for a transformation with Hyundai’s introduction of a nuclear-powered container ship using Small Modular Reactor (SMR) technology. Aimed at achieving decarbonization, the 15,000 TEU vessel incorporates innovative designs like the TerraPower’s Molten Chloride Fast Reactor. This initiative promises enhanced cargo capacity, safety features, and energy efficiency while targeting net-zero emissions in shipping. Collaborative regulatory efforts and strategic partnerships are essential for the industry’s transition to nuclear-powered transport by 2030.

Bunker tank soundings and fuel quantity calculation
Bychiefengineerslog 9 July 202219 August 2025
A merchant ship’s design includes tanks for cargo and fuel, with a focus on maintaining stability through regular monitoring of fluid levels. Accurate tank soundings are crucial for bunkering operations to prevent financial losses due to malpractices. Manual and automated methods complement each other to ensure precise fuel measurements and optimal performance.
