By the end of 2025, the company had accumulated 327 authorized patents (including 112 invention patents), led or participated in developing 19 national standards and 43 industry standards, and spearheaded the national science and technology major project “Marine Low-Speed Engine Engineering.” Its CHD620 engine model passed CCS type approval in 2024 and entered mass installation on vessels, achieving a thermal efficiency of 52.3%; its CHD32/40 series medium-speed engines have been deployed aboard key projects including “Fan Ya,” China’s first domestically designed and built 174,000-cubic-meter LNG carrier. In 2025, marine main engine deliveries increased by 18.6% year-on-year, with 31% exported to countries including Greece, Singapore, and Norway; its technical service network covers major ports across East Asia, Southeast Asia, the Middle East, and Europe. The company maintains long-term technology licensing and joint development collaborations with MAN Energy Solutions and Wärtsilä, offering integrated technical services—including technology licensing, localized manufacturing, testing and verification, and full-lifecycle operation & maintenance—to support cross-border consortium bidding, standard adaptation, and multilingual engineering delivery.

Dalian Shipbuilding Industry Group Co., Ltd. (DSIG), located in Dalian City, Liaoning Province, is a key state-owned enterprise directly managed by the central government and a core shipbuilding base under China Shipbuilding Group Co., Ltd. It was one of the 156 key projects during the First Five-Year Plan period and boasts an annual shipbuilding capacity exceeding 8 million deadweight tons, as well as comprehensive R&D, design, system integration, and total assembly and delivery capabilities across the entire shipbuilding value chain. The company’s core business spans five major sectors: military vessel development, civilian shipbuilding, offshore engineering equipment, high-end steel structure manufacturing, and integrated ship supporting systems. In chemical-related engineering service scenarios, DSIG provides critical support for specialized engineering needs associated with high-tech vessels such as LNG carriers, intelligent very large crude carriers (VLCCs), and polar research icebreakers—including low-temperature storage and transportation, smart energy management, polar corrosion-resistant structures, and dual-fuel propulsion system integration—serving industries including petrochemicals, liquefied natural gas (LNG) storage and transportation, deep-sea resource development, and marine environmental protection equipment. The company houses a national-level enterprise technology center, a national engineering laboratory (the Offshore Engineering Equipment Innovation Platform), and a postdoctoral research workstation. To date, it has been granted a total of 2,847 patents (including 1,321 invention patents) and has spearheaded or participated in the formulation and revision of 186 national, industry, and military standards, including key foundational standards such as GB/T 34000—2016 “China Shipbuilding Quality Standards” and CB/T 4474—2022 “Technical Requirements for Construction of Liquefied Natural Gas (LNG) Carriers.” DSIG has successfully obtained ISO 9001, ISO 14001, and ISO 45001 management system certifications, holds national secrecy qualification certification (Level I), a weapons and equipment research and production license, an A-level boiler and pressure vessel manufacturing license, and product recognition certificates from 12 globally leading classification societies, including China Classification Society (CCS), DNV, and BV. In 2024, DSIG also passed the EU MDR medical device compliance assessment for specially adapted vessels. Notable achievements include undertaking the overall construction of China’s three aircraft carriers—the “Liaoning,” “Shandong,” and “Fujian”—delivering 12 ultra-large 24,000 TEU dual-fuel container ships between 2022 and 2025, all of which meet the IMO Tier III emission standards; constructing the polar research icebreaker “Xuelong 2”; and launching in 2024 the world’s first demonstration project for a 300,000-ton intelligent crude oil carrier. Its products are exported to over 20 countries, including Greece, Singapore, Norway, and Brazil. In 2025, international orders will account for 41.7% of its total output. DSIG offers turnkey equipment packages compliant with international classification society standards, specialized material welding processes, digital twin system integration, and full-lifecycle technical services, supporting various cross-border cooperation models such as consortium partnerships, technology licensing combined with localized engineering implementation, and other collaborative approaches.
