Hudong Heavy Machinery (600150) has made great strides in the manufacture of "heart" products for ships. It has successfully developed the first and largest domestic marine high-power low-speed diesel engine ------MANB&W7K90MC-C marine diesel engine. Recently, the independent acceptance of the classification society, the shipyard and the shipowners has been successfully passed. Experts in the industry believe that the current domestically produced high-power low-speed diesel engine with the largest cylinder diameter and the highest power indicates that China's marine high-power low-speed diesel engine has broken through the 900mm cylinder diameter for the first time, indicating that the Hudong heavy-duty large-bore marine low-speed diesel engine manufacturing capacity It has reached a new level.

The MANB&W7K90MC-C diesel engine has a rated maximum continuous power of 31990 kW. This time it will be used for a 3,500-ton TEU (standard container) ship main engine manufactured by Shanghang Orange West Ship Co., Ltd. Due to the heavy size and large size of this diesel engine, it is more difficult in the process of casting, processing, heat treatment and assembly. The technicians of Hudong Heavy Machinery Co., Ltd. fully absorb the patented design technology of digestion and combine the company's commitment to the National Defense Science and Technology Commission. The 10,000-kilowatt diesel engine research project has completely completed the process test and pre-research work, and strengthened the process supervision and control to ensure the successful manufacture of the mainframe.

The reporter learned that as the backbone manufacturer of China's marine diesel engine industry, Hudong Heavy Machinery has achieved fruitful results in the development of new diesel engine models during the "Tenth Five-Year Plan" period. Its diesel engine product structure has gradually developed into a large-scale and intelligent direction, filling again and again. A blank for the manufacture of domestic marine high-power diesel engines.
