China Construction machinery information

Guide: when the shipbuilding industry capacity is gradually transferred to China, the upstream diesel engine capacity transfer is slow. The relevant data of the "digital production system of composite materials" developed shows that the self-sufficiency rate of domestic diesel engines is less than 50%, and more than half of them need to be imported. The reason that hinders the transfer of production capacity is the technical threshold. At present, Rongsheng heavy industry has built the country's largest 5million horsepower

when the shipbuilding industry's production capacity is gradually transferred to China, the upstream diesel engine production capacity transfer is slow. Relevant data show that the self-sufficiency rate of domestic diesel engines is less than 50%, and more than half of them need to be imported. The reason that hinders the transfer of production capacity is the technical threshold

at present, Rongsheng heavy industry has gradually formed the country's largest capacity of 5million horsepower. The survey found that the company's strategy to solve technical barriers is to actively cooperate with international diesel engine production giants on the one hand, and absorb domestic advanced technology on the other hand

build the country's largest marine diesel engine base

the shipbuilding industry has gradually taken the initiative to bear the cost transfer of the city's waste classification and treatment equipment to China dart company. From January to September this year, the National Shipbuilding Enterprises above Designated Size achieved a total industrial output value of 486billion yuan, an increase of 24.2% year-on-year. Insiders pointed out to Xiang that in the shipbuilding industry, the sales of marine diesel engines account for roughly 20% of the total sales of ships. Among them, the main engine of marine diesel engines is called the "heart" of ships, which is the most valuable supporting equipment, accounting for about 10% of the total ship price. It is estimated that the diesel engine main engine market will reach about 50billion yuan

however, this market has been monopolized by two foreign giants man and Wartsila. Their low-speed diesel engine products account for more than 90% of the world's share, accounting for more than half of the medium speed engine field. As a large manufacturing country, China relies heavily on imports of diesel engines. The domestic self-sufficiency rate is less than 50%, and more than half of them need to be imported. Data show that in 2007 and 2008, the diesel engine gap in China's shipbuilding industry was about 4.5 million horsepower. It is estimated that the supply and demand gap of marine main engines in China will exceed 10million horsepower this year

before this year, the production capacity of low-speed marine engines in China was mainly concentrated in the diesel engine enterprises affiliated to the two major shipbuilding groups, China Shipbuilding and China Shipbuilding Industry Corporation. In 2008, the total production capacity of low-speed marine engines in four diesel engine enterprises, including Hudong Heavy Machinery Co., Ltd. and Dalian shipbuilding Diesel Engine Co., Ltd., was 5.7 million horsepower. As the largest private shipbuilding enterprise in China, Rongan power, under Rongsheng heavy industry, has been planning to build a 5million HP diesel engine project since 2007. In March last year, the project was approved by the national development and Reform Commission; In October last year, the first low-speed diesel engine of Rongan power went offline; In April this year, the company received a total of 2.419 billion yuan of syndicated loans. In addition, Rongsheng heavy industries' IPO in Hong Kong also said in the preliminary prospectus that part of the funds raised will be used for diesel engine projects

however, the project has been questioned. The annual design capacity of the project is almost equal to the sum of the capacity of the three major machine manufacturing bases in China in 2008. Some commentators pointed out that there is overcapacity in domestic diesel engine production at present

in this regard, he Zaihua, senior researcher of CIC consulting, believes that the current domestic diesel engine production capacity belongs to the advanced investment and construction. Due to various factors, China diesel has just ordered a set of metering equipment from cannon, and the production capacity of diesel engine can not be effectively converted into actual products, and there is a disconnect between a large number of market demand and production capacity. Plastic manufacturers all know that plastic is mainly composed of resin

technology is one of the important reasons for disconnection. It is understood that in the production of marine diesel engines, low-speed engines have the highest technical requirements and the highest brand concentration. Man company is in an absolutely dominant position. In contrast, medium speed engines are relatively dispersed, which is also the entry point for many enterprises to enter the field of marine diesel engines. At present, domestic marine diesel engines with independent brands are also focused on medium speed engines
