On June 30, Hudong-Zhonghua ushered in a moment of concentrated delivery of green high-end vessels, with three clean energy ship types possessing globally leading technical standards being delivered ahead of schedule on the same day. The 174,000 cubic meter LNG carriers “GREENERGY CLOUD” and “PUTERI KEDAH” were delivered three months and five months early respectively, while the 13,000 TEU dual-fuel container ship “KOTA ELOK” was delivered six months ahead of schedule. The batch delivery of three high-tech, high value-added green vessels represents a major achievement in the company’s deep engagement in clean energy shipping equipment and lean batch construction, fully demonstrating the company’s robust capability to serve the global energy supply assurance and green shipping development landscape.
The “GREENERGY CLOUD” is the sixth vessel in the CNOOC medium-to-long-term FOB resource supporting LNG carrier project (Phase I) built by Hudong-Zhonghua. Katarzyna Serczewicz, Deputy Manager of the LNG Asset Management Department of Mitsui O.S.K. Lines, Hua Rui, Authorized Representative of the Ship and Offshore Business Division III of China Shipbuilding Trading Co., Ltd., and Wang Jiaying, Assistant General Manager of Hudong-Zhonghua, signed the vessel delivery documents on behalf of the three parties.
The “PUTERI KEDAH” is the second vessel built by Hudong-Zhonghua for the Petronas Kawasaki Kisen LNG carrier project. Xie Yihong, Director of the Energy Vessel Department of Kawasaki Kisen (China) Co., Ltd., Cao Mingsheng, Business Manager of the Ship and Offshore Business Division III of China Shipbuilding Trading Co., Ltd., and Wang Jiaying, Assistant General Manager of Hudong-Zhonghua, signed the vessel delivery documents on behalf of the three parties.
The “KOTA ELOK” is the first vessel in a series of 13,000 TEU dual-fuel LNG-powered container ships ordered by Pacific International Lines. Wei Bing, Assistant General Manager of Newbuilding of the Ship Management Department of Pacific International Lines, Deng Yewen, Project Manager of the Ship and Offshore Business Division I of China Shipbuilding Trading Co., Ltd., Zuo Dequan, Chief Builder of Civil Products of the Company and General Manager of Changxing Shipbuilding, signed the vessel delivery documents on behalf of the three parties.
Both “GREENERGY CLOUD” and “PUTERI KEDAH” are fifth-generation “Changheng” series LNG carriers independently developed and built by Hudong-Zhonghua. They have a total length of 299 meters, a molded breadth of 46.4 meters, and a molded depth of 26.25 meters. They are equipped with dual-fuel main engines featuring the latest intelligent Control Exhaust Gas Recirculation (iCER) system technology, offering numerous advantages such as excellent rapid response performance, low comprehensive energy consumption, outstanding low-temperature performance, strong tank type compatibility, lightweight lightship weight, prominent cargo capacity, convenient operation and maintenance, and high route adaptability. Through lightweight design, the lightship weight is reduced by 1,500 tons, allowing each voyage to carry an additional 800 cubic meters of LNG, equivalent to approximately 500 more tons, reducing daily carbon emissions by over 10 tons, lowering fuel and gas consumption by 10%, and reducing the daily LNG evaporation rate to 0.085%, reaching globally leading levels. Their navigational adaptability is equally outstanding, covering over 90% of global LNG trade routes and capable of reaching 120 LNG terminals across continents worldwide.
The delivery of “GREENERGY CLOUD” marks the successful conclusion of the CNOOC Phase I project, achieving a milestone accomplishment in China’s largest LNG carrier construction project. To date, Hudong-Zhonghua has completed the construction of six large LNG carriers: “GREENERGY YING”, “GREENERGY ZHU”, “GREENERGY XING”, “GREENERGY YUE”, “GREENERGY FENG”, and “GREENERGY CLOUD”. These six giant vessels are fully serving CNOOC’s medium-to-long-term FOB resource transportation business, significantly enhancing its annual transportation capacity. As of now, the “GREENERGY” series LNG carriers are operating in good condition, with their tracks covering ports in Europe, the Americas, Asia, and Africa. Due to their excellent design standards and outstanding environmental performance, they have received high recognition in the international market. The first vessel “GREENERGY YING” and the second vessel “GREENERGY ZHU” were respectively awarded the “Green Ship Award” for 2024 and 2025 by the Maritime and Port Authority of Singapore (MPA).
The “PUTERI KEDAH” is the second vessel built by Hudong-Zhonghua for the Petronas project. Like the first vessel “PUTERI JOHOR”, its cargo tank core system is fully equipped with domestically produced ultra-low temperature valves. Simultaneously, it fully responds to IMO and IACS regulations, making it one of the first Hudong-Zhonghua vessels to successfully obtain DNV Cyber Secure SP0 cybersecurity certification, filling the gap in cybersecurity implementation pathways during the design phase, promoting a shift from “passive defense” to “active upgrade” in vessel cybersecurity, and building a solid digital defense line for smart shipping.
The “KOTA ELOK” is a green and environmentally friendly container ship independently developed and designed by Hudong-Zhonghua, tailored for the shipowner’s specific routes. It has a total length of 335 meters, a molded breadth of 51 meters, and a molded depth of 27.2 meters, with a maximum container capacity exceeding 13,000 TEU (twenty-foot equivalent units) and capable of carrying 2,200 reefer containers.
The “KOTA ELOK” is equipped with an LNG dual-fuel power propulsion system, featuring a 12,000 cubic meter Type-B LNG fuel tank and a Fuel Gas Supply System (FGSS) independently developed by Hudong-Zhonghua, ensuring a super-endurance range of 22,000 nautical miles in gas mode. It incorporates multiple energy-saving designs, including optimized hull lines, an independently developed wind deflector, and advanced automation and digital systems, providing the crew with a more ergonomic operating environment.
In November 2023, Hudong-Zhonghua surpassed foreign competitors in construction efficiency for the first time. In January 2026, the company achieved a construction speed of 16 months for large LNG carriers, setting a new world record. All three vessels delivered this time were handed over significantly ahead of schedule, marking that the company’s construction efficiency indicators have reached a world-class level globally.
