en.Wedoany.com Reported - At the 2026 Posidonia Maritime Exhibition held in Greece this week, the 708 Research Institute, under China State Shipbuilding Corporation Limited, showcased five independently developed key green and intelligent new ship types, fully demonstrating China's innovative strength in ship design. These five new ship types cover tankers, bulk carriers, container ships, and gas carriers, with three of them setting global records.
World's Largest Pure Electric Propulsion Oil/Chemical Tanker
The 33,500 DWT product oil/chemical tanker is a new-generation ultra-wide, shallow-draft IMO Type II product oil/chemical tanker developed by the 708 Research Institute based on its star 24,000 DWT series twin-screw ship type. It adopts pure electric propulsion and is currently the world's largest pure electric propulsion oil/chemical tanker.
This vessel has an overall length of approximately 183 meters, a beam of 38 meters, a full-load draft of only 7.25 meters, and a deadweight tonnage exceeding 33,500 tons, offering a significant advantage in cargo-carrying performance under shallow draft conditions. The service speed is 12.5 knots, with main propulsion provided by two propulsion motors of approximately 3,900 kW each, and the main power plant consists of four generator sets of approximately 3,000 kW each. Equipped with a bow tunnel thruster of about 1,000 kW, the vessel boasts excellent maneuverability.
World's First Green Suezmax Vessel
Following the blockade of the Strait of Hormuz, which disrupted the normal transport of large quantities of crude oil from the Persian Gulf, the Red Sea route via the Suez Canal has become increasingly important. The 708 Research Institute independently developed a 220,000 DWT crude oil tanker based on the maximum dimensions permitted for passage through the Suez Canal. This vessel is also the world's first green Suezmax ship type.
With an overall length of 299.9 meters, a beam of 54 meters, a draft of 19.2 meters, a maximum deadweight of 220,000 tons, and a cargo capacity of 1.5 million barrels of crude oil, this vessel is 50% larger than traditional Suezmax tankers. Through innovative hull dimensions, this Suezmax tanker will significantly enhance the efficiency of crude oil transportation between Eurasia through economies of scale, addressing the limitations where Very Large Crude Carriers (VLCCs) cannot transit fully loaded and traditional Suezmax vessels fail to fully utilize the canal's capacity.
World's Largest VLGC Capable of Transiting the Old Panama Canal Locks
The 90,000 m³ Very Large Gas Carrier (VLGC) is a new-generation ultra-large LPG/ammonia carrier independently developed by the 708 Research Institute. Evolved from the institute's mature 88,000 m³ VLGC ship type, it is the largest VLGC capable of transiting the old Panama Canal locks, offering enhanced operational flexibility. The vessel has an overall length of 229.9 meters, a beam of 32.25 meters, and features Type A independent cargo tanks. The design optimizes performance and cargo tank utilization within the constraints of principal dimensions, achieving a cargo tank capacity of 90,000 m³.
This vessel not only meets conventional LPG transport needs but is also safely compatible with ammonia transport, precisely addressing the growing demand for ammonia maritime shipping. It deeply aligns with green and low-carbon development trends, providing customers with future-oriented tonnage that balances economy and environmental friendliness. Additionally, the vessel is equipped with an LPG dual-fuel main engine and a shaft generator, combined with the 708 Research Institute's independently developed vertical bow line type, as well as energy-saving devices such as ducts, rudder bulbs, and twisted rudders, significantly enhancing ship performance.
The 6,500 TEU container ship is a new-generation wide-beam medium-sized container ship developed by the 708 Research Institute in response to market demand. It complies with IMO conventions and regulations in effect, as well as green, energy-saving, safe, and environmentally friendly requirements for routes to Europe, the Americas, Australia, and New Zealand. The vessel also features an ammonia-ready design, providing sufficient conditions for future conversion to ammonia fuel propulsion, enabling zero-carbon emissions. With an overall length controlled within 240 meters, it is adaptable to more terminals and ports; it offers extensive route deployment, suitable for routes such as China-Australia, Mediterranean-Canada, and Asia-South America.
The newly unveiled 180,000 DWT Capesize bulk carrier, after overall optimization, achieves a maximum deadweight of 184,000 tons at a draft of 18 meters, while maintaining low fuel consumption characteristics. The design comprehensively optimizes key structures such as the ballast stripping system, allowable bending moment and shear force during loading/unloading operations, and cargo hatch openings, effectively improving loading/unloading efficiency. It accommodates both general cargo in holds and deck cargo, significantly enhancing overall cargo-carrying capacity. Furthermore, the vessel has simultaneously completed development of multiple alternative fuel versions, including LNG, ammonia, methanol, and ethanol power solutions, and is equipped with wind-assisted propulsion systems and high-voltage shore power systems, balancing operational economy with green and environmental requirements.
