On May 15th, the world's first fifth generation "Changheng Series" 174000 cubic meter large transport ship, "Green Energy Ying," independently developed, designed and built by the company, was named and delivered five months in advance. This "offshore super refrigerated vehicle", innovatively developed by the company and representing the highest technological level in the field of large LNG transport ships in the world, has finally transformed from a construction drawing to a real scene drawing. The emergence of the "Green Energy Ying" has become a landmark event for China to move from "following" to "leading" in the world LNG shipping industry.

Ms. Ding Wei, the guest speaker, named the new ship. Xu Chunrong, Director of the Equipment Industry Department of the Ministry of Industry and Information Technology, Wang Jianbo, Deputy General Manager of China National Offshore Oil Corporation (CNOOC), Feng Bo, Deputy General Manager of China COSCO Shipping Group Co., Ltd., Wang Zheng, a member of the Party Group and Deputy General Manager of China Shipbuilding Corporation, delivered speeches. Weng Hongbing, Deputy Secretary of the Party Committee and General Manager of the company, presided over the naming ceremony. Nearly 200 guests from CNOOC Group, China COSCO Shipping Group, Mitsui Corporation of Japan, American Classification Society, China Classification Society, GTT, captain of the new ship, on-site supervision team, company leaders, and old leaders Chen Jun attended the ceremony.

The world's first fifth generation "Changheng series" 174000 cubic meters large transport ship "Green Energy Ying"

The "Green Energy Ying" is the first ship of China's largest LNG transport ship construction project, the "China National Offshore Oil Corporation's Medium - and Long Term FOB Resource Supporting LNG Transport Ship Project". It has a total length of 299 meters, a width of 46.4 meters, and a depth of 26.25 meters, and is classified by the American Bureau of Shipping (ABS) and China Classification Society (CCS). The ship adopts the latest intelligent control exhaust gas recirculation (iCER) system technology installed on the Chinese ship WinGD 5X72DF2.1 dual fuel main engine, which is of great significance for ensuring energy transportation security in China, effectively enhancing the independent and controllable ability of China's LNG transportation industry chain, and helping China build a strong manufacturing and maritime country.

This "Changheng Series" ship type, which combines the latest design concept, the best technical equipment, the strongest environmental protection performance, the most forward-looking, and the essence of the company's previous four generation LNG ship design, has four significant highlights:

● Fast and good performance, low overall energy consumption

By adopting the fourth generation of Shanghai East China twin stern fin configuration, the best match was achieved between reducing self-propelled resistance and improving stern propulsion efficiency, achieving excellent integrated coupling efficiency of the propulsion chain. Through multiple rounds of European water tank experiments, it has been verified that excellent navigation efficiency can be achieved in both medium and high speed ranges. Compared to the previous generation of ships, daily navigation reduces carbon emissions by more than 10 tons.

● Good low-temperature performance and wide cabin compatibility

The design of this type of ship fully considers compatibility and universality, and can be equipped with both NO96 series and MARK III series enclosure systems. Especially when equipped with the latest generation NO96 Super+system, the evaporation rate is reduced by 15% compared to the previous generation L03+system, reaching 0.085%, providing a wider range of oil and gas balance speeds for low-carbon navigation. It can reach 120 LNG shore stations on all continents around the world, with excellent global universality.

● Empty ships have a light weight and strong cargo carrying capacity

The entire ship adopts an integrated lightweight design concept, optimizing the empty ship weight from multiple dimensions. Compared to the previous generation of ships, the total weight of the ship has been reduced by more than 1500 tons, and the cargo hold loading rate is higher. Each voyage can load an additional 800 cubic meters of LNG.

● Skilled operation and maintenance, excellent route matching

The ship can be equipped with a re liquefaction system of 1.5 to 2.3 tons, which can adapt to different balance utilization requirements of evaporation gas on short, medium, and long routes. The ship has strong maneuverability and economy, and can efficiently adapt to various operational requirements of diversified routes.

It is understood that the "China National Offshore Oil Corporation's Medium - and Long Term FOB Resource Supporting LNG Transport Ship Project" is divided into phases one and two, with a total of 12 174000 cubic meter LNG ships built. If fully put into operation, approximately 7 million tons of LNG will be transported back from around the world each year, which can meet the needs of 54 million households for nearly a year. This is of great practical significance for adjusting China's energy structure, improving environmental quality, improving people's living standards, and promoting coordinated economic and environmental development.

In December 2021, the "Chang Heng series" ship types obtained certificates such as General Design Approval (GDA) and Pre Classification Approval (PCA) from four internationally renowned classification societies, including ABS, BV, LR, and DNV. They successfully obtained a permit for actual ship construction, which attracted global attention and orders flooded in. As of now, the company has undertaken a total of 34 ships, becoming the brightest "pearl" in the international LNG ship market.

The company has been deeply involved in the LNG field for 27 years, continuously breaking through key technological barriers and core capability bottlenecks. Its products have achieved full coverage from nearshore to ocean, from inland to inland rivers, and from small to large to super large. It has delivered more than 40 LNG storage and transportation equipment. It is worth mentioning that at the end of April this year, the company undertook the construction contracts for 18 of the world's largest 271000 cubic meters ultra large LNG transport ships, setting a record for the world's largest single shipbuilding order, demonstrating its strong strength in the field of high-end marine equipment.

The company will work together with partners such as China National Offshore Oil Corporation (CNOOC), COSCO Shipping, and China Merchants Mitsui to build the world's latest generation of LNG ships, provide first-class equipment for China's clean energy transportation, and make new contributions to better serve the country's energy development strategy.
