The Marine Design and Research Institute of China (MARIC) has achieved a significant milestone with the Approval in Principle (AiP) from Bureau Veritas for its 155,000m³ ultra large ethane carrier (ULEC).
Global transportation
This innovative vessel is designed to enhance the global transportation of ethane through improved capacity, sustainability, and operational flexibility. At approximately 274 meters in length and 42 meters in breadth, the ULEC represents one of the largest vessels in its class, with the capability to carry ethane, LPG, ethylene, and propylene.
The vessel features compatibility with both GTT Mark III membrane tanks and Type B tanks, allowing shipowners to select the most suitable cargo containment system. It is powered by a MAN ME-GIE dual-fuel engine that operates on ethane, contributing to reduced emissions and improved fuel efficiency. MARIC’s design incorporates multiple energy-saving technologies, including optimized hull lines, propeller cap fins, a pre-swirl duct, and a shaft generator to lower fuel consumption and environmental impact.
To further enhance operational performance, the ship will integrate MARIC’s Smart Ship Solution. This includes a Smart Navigation System, an Energy Efficiency Management System, and a Machinery Health Management System. These technologies work together to improve navigation safety, energy use, and the reliability of onboard machinery. According to MARIC’s leadership, the AiP reflects the institute’s continued efforts to advance next-generation gas carriers that align with modern sustainability standards.
Bureau Veritas, which reviewed the ULEC under its marine classification framework, emphasized that the design aligns with current safety, efficiency, and sustainability criteria for gas transportation. The classification society expressed support for MARIC’s forward-thinking approach and its contributions to the evolution of ultra-large gas carriers. This development also follows MARIC’s recent AiP from DNV for an ammonia-ready Kamsarmax bulk carrier, showcasing the company’s commitment to innovation in green shipping.
