Chinese private shipbuilder Zhoushan Changhong International Shipyard Co., Ltd. (hereinafter referred to as “Zhoushan Changhong International”) has incorporated Zhejiang Zengzhou Heavy Industry Technology Co., Ltd. (hereinafter referred to as “Zengzhou Heavy Industry”) as a wholly-owned subsidiary.
According to the National Enterprise Credit Information Publicity System, Zengzhou Heavy Industry’s controlling shareholder has changed. The change information column indicates that on September 15, 2025, Zengzhou Heavy Industry’s investor (including investment amount, investment method, investment date, and investor name) changed from Zhoushan Hongzhou Ship Building Co., Ltd. to Zhoushan Changhong International.
Notably, this marks the second change in controlling shareholder for Zengzhou Heavy Industry in 2025. On January 17, 2025, the investor of Zengzhou Heavy Industry shifted from Zengzhou Group Co., Ltd. to Zhoushan Hongzhou Ship Building, with only eight months elapsing between the two changes.
Public records indicate that Zhejiang Zengzhou Shipbuilding was formerly a wholly-owned subsidiary of Zengzhou Group. Established on August 20, 2007, the facility occupies a 500,000-square-meter site with 800 meters of deep-water coastline. It stands as one of Zhoushan City’s key projects for attracting large-scale ship repair and construction industries.
At the end of December 2019, Zhejiang Zengzhou Shipbuilding changed its name to Zhejiang Zengzhou Heavy Industry. Its last new ship order prior to the name change was secured in January 2018 from German shipowner Tom Worden Schiffs for four 7,350 DWT general cargo vessels. The delivery dates were scheduled for March, June, September, and December 2020. In July 2021, Zengzhou Heavy Industry made its final media appearance as a shipyard with the delivery of the Zhihai, a major national engineering platform jointly developed with CSSC Ninth Design & Research Institute(CSSC NDRI).
As one of the first batch of 51 “white list” shipyards of the Ministry of Industry and Information Technology, Zengzhou Heavy Industry also failed to escape the cyclical downturn in the shipbuilding industry.
The Dinghai District People’s Court of Zhoushan City, Zhejiang Province, ruled to accept the reorganization application filed by Zengzhou Heavy Industry, as well as the application for substantive merger and reorganization of six affiliated companies, including Zhoushan Zengzhou Marine Equipment Manufacturing Co., Ltd. Zengzhou Heavy Industry officially completed its equity restructuring in February 2025.
However, just over half a year later, Zengzhou Heavy Industry underwent another change in ownership, becoming wholly owned by Zhoushan Changhong International. With this, the long-established shipbuilding enterprise officially joined the “Changhong Group.”
According to the official website, Zhoushan Changhong International was invested and established by Jiangsu Xin Changjiang Group in 2009. It is a large-scale shipbuilding industry enterprise with a full industrial chain integrating shipbuilding, ship repair, ship breaking and metal resource utilization.
In terms of shipbuilding, Zhoushan Changhong International has formed a high-end shipbuilding route with small and medium-sized container ships, gas transport and bunkering ships and large bulk carriers as the main products, and is developing into large container ships, large ore carriers, chemical tankers and offshore engineering ships. The company continuously optimizes its product portfolio and enhances product quality.
At present, Changhong International has established three major shipbuilding and repair industrial bases in Dinghai District, Putuo District and Daishan County of Zhoushan City, namely Zhoushan Changhong International (headquarters), Zhoushan Putuo Changhong Ship Repair and Zhoushan CIMC Changhong Ship Repair Co., Ltd. The three bases have a total investment of over 10 billion yuan, cover an area of over 6.5 million square meters, and have a total coastline of more than 20,000 meters. The annual shipbuilding capacity exceeds 5 million deadweight tons, the annual ship repair capacity is more than 500 ships, and the annual ship dismantling capacity is 1.2 million light tons.
