Yesong Shipyard was built in Tongzhi of Qing Dynasty for four years. It was originally an American enterprise, engaged in the design and construction of docks, dams and warehouses. Ten years after Tongzhi, he obtained the lease right of "Old Wharf" of Shanghai Wharf Company at the highest bid price. The following year, it was granted the lease right of Pudong Terminal Company. At first, it expanded the Pudong Wharf from 380 feet to 450 feet, then added cranes, boilers and pumps one after another, and then merged some British shipyards in Shanghai. Due to the increasing British capital, Yesson Shipyard has become a British capital enterprise. It is bigger than Xiangsheng Shipyard, with more than 2,000 workers. Its factory in Hongkou "Old Wharf" covers an area of more than 30 mu, with Rentai Wharf in the east, China Merchants on both sides, Zhonglu Stack in front and Huangpu River in the back. There is a railway on the ground, allowing heavy vehicles to enter and exit, and the equipment is relatively advanced. From the 20th year to the 26th year of Guangxu, Dongjiadu Wharf and Dongfang Wharf merged one after another, and the scale was further expanded. In the 27th year of Guangxu, Ye Song and Xiang Sheng merged to form Ye Song Shipbuilding Company with a capital of 5.57 million yuan. It has seven shipyards, namely Xiangsheng Shipyard, Old Shipyard, Yinxianggang Shipyard, Hefeng Shipyard, Dongjiadu Shipyard, Golier Shipyard and Dongfang Shipyard, as well as many factories, warehouses, docks and other equipment and facilities. It was one of the largest monopoly organizations in the east at that time.
The initial capital of Rong Rui Shipyard was 2 18490 taels of silver, and then the capital was increased by 654380 taels of silver. The site is located at Yangshupu Road, 1 Wharf, and the latest equipment is installed, including hydraulic nailing machine, steam tools and electric drilling machine. After the merger of Wanlong Iron Works in the first year of the Republic of China, the equipment was further expanded, and 1 50 horsepower electric winch was installed on the slideway, and two hand cranes were installed in the iron works. A ceiling for storing carpenters' dry wood, 65,438+0 new carports and 65,438+0 solid fire rooms were built in Bandung workshop. The copper casting workshop has been reformed, adding planer 1 set and 3 electric drills.
In 25 years of the Republic of China, Yesong Co., Ltd. merged with Rong Rui Shipyard to form Lianying Shipyard Co., Ltd., covering an area of 450 mu, with nearly 65,438+10,000 employees and four large docks. 1 year, more than 570 ships were repaired, and the business situation was very good.
After liberation, during the three-year national economic recovery period from 1950 to 1952, the factory invested 720,000 yuan in capital construction to carry out sporadic construction and workshop repair.

Shipbuilding, machine building, ship repairing and non-ship products have become the main production and operation projects of the factory.
Before 1957, the main task of the factory was to repair ships, and from 1958, it entered a new period of development with equal emphasis on ship repair and shipbuilding. 1958 developed the first 2000 HP marine diesel engine in China. 1959, the 3000-ton coastal cargo ship "Heping 49" was built. Starting from 1970, when the 10,000-ton ocean-going cargo ship "Lei Feng" was built on the 3,000-ton platform, more than 30 large and medium-sized ships were designed and built, and more than 60 large and medium-sized marine diesel engines were manufactured. Shipbuilding machinery has become the main body of factory production. Since the 1980s, large foreign ships have been taken as the main body of ship repair, special ships and offshore oil drilling platforms have been transformed, and 1 1 ship professional technical maintenance service station has been established in cooperation with foreign businessmen, and the ship repair capacity is among the best in China. This machine is from Sulzer and B&; Denmark; Patented, manufactured several series of Sulzer marine diesel engines. Since 1969, large-scale ships such as multi-purpose cargo ships, container ships and refrigerated ships designed by ourselves or jointly have been built in batches and exported to Poland, Germany, Cyprus, Singapore, Cuba, Iran and other countries. We also cooperated with 708 Research Institute to design and build the first semi-submersible offshore oil drilling platform "Exploration 3" in China.
The factory also undertakes the manufacture of large-scale mechanical equipment, large-scale steel structure, tunnel shield boring machine, Wusong Road Gate Bridge main bridge and gate required by key projects of water conservancy, metallurgy, urban construction and other departments. From 1985 to1September 1992, 26 kinds of bronze art castings and large marine castings were exported to the United States, Japan, Egypt, Canada, the Philippines, Indonesia and other countries and Taiwan Province Province, Hongkong and Macau. From 1977 to 1995, the factory won 2 national invention awards, 3 scientific research projects 103,10/4 times, and 32 products won 53 scientific and technological achievement awards or high-quality product awards from the state, the Ministry (China Shipping Corporation) and Shanghai. Among them, 6RND68M diesel engine won the Golden Dragon Award as the national excellent new product, and the export container ship 1.23 million tons and the "Exploration 3" drilling platform won the national gold medal.
