China's major marine equipment production increased
The "Eleventh Five-Year Plan" period is a special period in the history of China's shipbuilding industry. It is not only the fastest-growing period, but also the period of exposing deep-seated contradictions and problems, and thus becoming an important turning point in the development of the ship supporting industry.
The scale of the economy has expanded significantly year by year.
During the "11th Five-Year Plan" period, China's shipbuilding industry achieved rapid development, and major economic indicators have increased substantially year by year, hitting record highs, and the economic strength of enterprises has been continuously enhanced. At the end
According to the "China Shipbuilding Industry Yearbook" from 2007 to 2011, between 2006 and 2010, the number of marine equipment manufacturing enterprises above designated size increased from 252 to 740; the total industrial output value increased from 24.98 billion yuan to 76.91 billion yuan. The main business income increased from 23.65 billion yuan to 63.2 billion yuan; the export delivery value increased from 3.96 billion yuan to 10.32 billion yuan; the total profit increased from 1.59 billion yuan to 4.18 billion yuan (as of January-November 2010). The average annual growth rate of these five indicators is 30.9%, 32.5%, 27.9%, 27.0% and 27.3%.
The output of major equipment is increasing year by year.
From 2006 to 2010, the output of China's marine low-speed diesel engines increased from 132 units to 2.28 million horsepower to 336 units/6 million horsepower. The output of marine medium-speed diesel engines increased from 8,145 units to 16,242 units. The output of marine high-speed diesel engines increased from 4,927 units to 12,687 units. The output of marine cranes increased from 333 to 1018, the output of marine anchor winches increased from 765 to 3271, and the output of marine steering gear increased from 206 to 422.
During the “Eleventh Five-Year Plan†period, China's large and medium-sized marine diesel engines and major marine equipment expansion projects such as crankshafts and deck machinery were launched. From the end of the "Tenth Five-Year Plan" to the end of the "Eleventh Five-Year Plan", the number of low-speed marine enterprises increased from three to 13. The number of low-speed marine crankshaft enterprises increased from two to five, and the number of marine medium-speed machine enterprises increased from five to over. In 10 companies, the number of medium-speed crankshaft enterprises has increased from one to three, and the number of large and medium-sized deck machinery enterprises has increased from five to nearly 20. At the end of the “Eleventh Five-Year Planâ€, the capacity of China's low-speed marine engines reached more than 10 million horsepower, and the capacity of marine low-speed crankshafts reached more than 300. The medium-speed machine capacity for export vessels and domestic ocean-going vessels reached more than 2,200. The crankshaft capacity has reached nearly 1,500. The situation in which several major marine equipment and core components are in short supply has been alleviated to some extent.
The shipping rate of domestically produced marine equipment is increasing year by year.
Through the calculation of the localization equipment loading rate of various types of ships built by China Shipbuilding Industry Corporation and China Shipbuilding Industry Corporation from 2006 to 2009, and referring to the localization of typical ship supporting equipment in 2008 by the CSIC Economic Research Center. According to the survey results, the current situation of China's local equipment shipment rate at the end of the “Eleventh Five-Year Plan†is estimated as follows: the average level of localized equipment loading in China has exceeded 40%, but less than 50%; bulk carriers, oil tankers, container ships The average level of localized equipment loading rate of the three major ship types has exceeded 50%, of which the average level of bulk carriers has reached or exceeded 65%, the average level of oil tankers is close to 50%, and the average level of container ships is close to 40%; The average loading rate of localized equipment is below 25%.
Major breakthroughs in localization and independent research and development of equipment
During the “Eleventh Five-Year Plan†period, significant progress was made in the localization of major marine equipment for key enterprises. Manufactured and delivered ultra-large marine low-speed diesel engines such as 8K98MC, 8K90MC-C, and 7RTA84TD; 7RT-Flex84T-D, 6RT-flex50B, 6RT-flex60C-B, 7RT-flex68B, 8RT-flex68D, 6S50ME-B, 6UEC43LSII, YB- Intelligent marine low-speed diesel engine such as 1926S42MC; new marine medium-speed machine such as 8L32/40, 12V32/40, 7L27/38, L23/30H, 6DKM-28, DK-20, DK-28; 8K90MC-C, 8K80MC-C, 8RT-flex68D, 6S70MC-C, 6RT-flex50B and other high-power low-speed diesel engine crankshafts; the localization rate of parts for marine low-speed and medium-speed mature models has reached 70% and 80% respectively. Power systems (hosts, propellers) or deck machinery for some very large vessels, high value-added vessels (eg VLCC vessels, VLOC vessels, 4,250 TEU container vessels, 8,530 TEU container vessels, 10,000 TEU container vessels, 177,000 tons bulk carriers) We have achieved domestically.
The company's independent research and development capabilities have been significantly enhanced, and a large number of marine equipment with independent intellectual property rights have been successfully developed. Some of the products have reached the international advanced level in terms of technology and quality, replacing imports. These products include: marine medium speed, low speed engine crankshaft, speed engine crankshaft, marine high-speed machines, transmission, large marine gear boxes, large propeller, large windlass, KGW crane, large marine twin cranes, turn vane steering gear, large-scale low pressure drag embrace, winches, marine engineering vessel / platform cranes, marine central cooling system control devices, sewage treatment plant, the new plate desalination plant, fire extinguishing equipment, separators, ship ballast water treatment system , large marine water purification equipment, rescue / rescue boat, high speed boat, ship power station equipment, high voltage generator, the new marine medium voltage distribution board, marine automatic transfer switch, high-voltage frequency digital marine shore power system, voyage data recorder, NC autopilot ship, ship steering control system, the ship dynamic positioning system, hold water detection and alarm devices, and electronic chart application system, alarm monitoring equipment ship, ship integrated management system, alarm level measurement, Fin stabilizer, marine high power dynamometer, intelligent marine navigation light / signal light control The ship supporting industry is gradually transforming from manufacturing to manufacturing and independent research and development.
