in the "megawatt" era of offshore wind power, how can lubrication management be upgraded to "go offshore"

China Construction Machinery Information

data show that China's coastal wind energy resources are relatively rich. By the end of 2019, the cumulative capacity of offshore wind power is 5.928 million KW, ranking third in the world. The offshore wind power market has ushered in an unprecedented upsurge of investment and installation, and the industry is also facing considerable challenges while grasping the opportunities. Compared with onshore wind power, the operating environment of offshore wind power is more rigorous. The characteristics of high unit failure rate, poor accessibility and short oil change window put forward higher requirements for lubrication and oil change services. The growing market volume will also greatly increase the demand for operation and maintenance services

as a digital full media matrix platform integrated with the gene of automotive engineering machinery, China engineering machinery information (), China Lubricant information (), lubricant market magazine, and China tire business () are specially planned to discuss the pain points and difficulties faced by the current offshore wind power operation and maintenance through visiting well-known wind power manufacturing bases and talking with experts in the industry

the proportion of direct drive fans has increased,

China leads the recovery of the global wind turbine lubricating oil market

recently, Kline Co, a global consulting service and market information provider, released the statistical data of "global market analysis and business opportunities of wind turbine lubricating oil". The annual compound growth rate of the demand for wind turbine lubricating oil was 13% driven by the continuous growth of global wind power installed capacity during the years. Last year, the total installed capacity of global wind power exceeded 650 GW, and the demand for fan lubricating oil also increased to 40000-50000 tons, with a market value of 400-500 million US dollars. Despite the impact of the COVID-19, the global consumption of fan lubricating oil will continue to decline this year and next, but it is expected to rebound rapidly thereafter

the project leader of Clariant energy business said that the core position of wind energy in the field of alternative energy has led to rapid growth in its market segment. "Although fan lubricating oil only accounts for a small part of the total lubricating oil market, considering the positive prospects of the wind power industry, the fan lubricating oil market is expected to become a quite important increment." The report also pointed out that in the next five years, China's new installed capacity of wind power will account for nearly 40% of the global total, which means that China will become a key market for wind turbine lubricants

Klein also pointed out that with the increasing market share of direct drive fans, the proportion of the lubricating grease mainly used in this model in the fan lubricating oil market will gradually increase. It is expected that it will always be on the rise before 2024, and China will also occupy a leading position in the global fan lubricating grease market

the practice of Jinan experimental machine we have seen in the world should be called the "megawatt" era of wind power on material experimental machine.

operation and maintenance focuses more on the full life cycle cost.

as an important part of wind power, offshore wind power develops rapidly with the support of technology and policy, and vigorously accelerates the development process of global wind power. Due to the abundant and stable offshore wind resources, the development of wind farms from land to sea has become a new trend in the world. The advantages of offshore wind power are mainly that the wind speed is larger than that on land, the wind vertical shear change is small, the turbulence intensity is small, there is a stable signal dominant direction, and the annual utilization hours are long. In addition, offshore wind power does not occupy land resources, and is close to the coastal power load center. Local consumption avoids the waste of resources caused by long-distance transmission. Tetra Pak aseptic packaging with biological materials plastic and a 30mm lightweight cover has been sold worldwide. According to statistics, the new installed capacity of global offshore wind power in 2019 hit a record high, breaking 6Gw for the first time

in recent years, the large-scale characteristics of global offshore wind turbine technology development have become increasingly obvious, which is also the objective need to achieve intensive sea use and reduce initial investment and later operation and maintenance costs. Today, China's major offshore wind turbine manufacturers have basically entered the "megawatt" era. Goldwind technology and Mingyang intelligent released and rolled off 8mW offshore turbines, Dongfang wind power released and rolled off 10MW offshore turbines, China offshore installation released 10MW offshore turbines, Xiangdian wind energy also announced the research and development of MW offshore turbines, and Taiyuan Heavy Industry has also completed the design certification of 8mW offshore turbines... For the current domestic market, Fujian and Guangdong are the main battlefields for offshore turbines above 8mW. With strong wind power, Limited sea area, accessibility of operation and maintenance, and the pressure of affordable times, developers will also increasingly favor offshore wind turbines with larger capacity from the perspective of economy

according to the data of China Renewable Energy Association, before 2017, the average commercial wind turbine capacity of the global offshore wind power market was less than 5 MW. In 2018, the average capacity of the global offshore wind turbine exceeded 7 MW, which is expected to reach 8 MW in 2020 and 10 MW in 2023. Among the offshore wind power projects developed in the past two years, European offshore wind power units of more than 6 MW have occupied the mainstream, and models of more than 6 MW account for 80%. Offshore wind power units in China are mainly 4 MW, and units of more than 6 MW are gradually increasing. This year, the installed maximum power offshore wind power models in China have exceeded 7 MW, reaching the average capacity of global offshore wind turbines

as the era of megawatt wind turbines begins, offshore wind power operation and maintenance will also face new challenges. With the increase of single unit capacity of wind turbines, the kWh cost of offshore wind turbines has fallen by half in the past six years. After the fan power is increased and the blade diameter is expanded, the annual power generation also increases. In addition to the increase of power generation, high-power fans can also effectively reduce costs. Under the same installed scale, the larger the power of a single machine, the fewer fans need to be installed, resulting in the reduction of costs. For example, the operation and maintenance of offshore wind power accounts for 25% to 30% of the cost of the whole project life cycle. The less the number of wind turbines in the wind farm, the lower the operation and maintenance cost. Users should not only choose the right manufacturer when purchasing tensile testing machines

Shanghai Electric completed the hoisting of its first 8mW offshore wind turbine in Shantou

insiders said that during the development of wind power projects, whether the wind turbine can play its best performance within the rated operation period is one of the key factors to measure the success or failure of wind farm investment. Therefore, in addition to the excellent quality of the fan itself, the operation and maintenance within its life cycle is more critical. With the innovative development of offshore wind power operation and maintenance, the connotation of offshore wind power operation and maintenance will have new changes in the future, that is, the concept of full life cycle will promote the specialization and systematization of wind power operation and maintenance services; There are high, medium and low-end O & M market stratification. As an important part of wind power operation and maintenance, wind power lubricants are also facing professional and systematic upgrading with the concept of full life cycle as the core

as the era of wind power subsidies is coming to an end, land-based wind power projects will achieve parity in 2021, and the state will no longer subsidize, and offshore wind power projects will no longer subsidize after 2022; The second is whether the orders of wind power equipment can be delivered in time under the epidemic and whether the annual delivery expectations can be fulfilled. At present, there will be some gaps in key components. In the second half of the year, the speed of customer picking up goods will increase rapidly, and the impact of the upstream supply chain has not been fully transmitted, which will have a serious scissors difference impact. The relevant person in charge said that next year is the last year of offshore wind power subsidies, and there is still more room for customer demand to improve. "In general, the guarantee of delivery next year is better than this year. This year is a land-based merger. After this peak this year, the supply chain capacity will support more offshore wind power next year, and more will be transferred to offshore wind power, such as bearings, blades and other key parts in short supply this year. Next year, the support for offshore wind power will be better."

the 13th five year plan for wind power development issued by the national energy administration points out that it is necessary to break through the design and manufacturing technology of 10 MW high-capacity offshore wind turbines and key components. With the trend of large-scale development of offshore wind turbine technology in the world becoming more and more obvious, it is urgent to solve the technical problems. Industry experts pointed out that the application and development of semi direct drive technology in offshore fans is at the right time. On the whole, direct drive units have no gearbox, and the failure rate is low, but the cost is high; Due to the fast speed of the gearbox, the failure rate of the double fed unit is high, but the cost is low; The semi direct drive units are divided into high-speed permanent magnet and medium speed permanent magnet models. The former has the same problem as the double fed unit, while the latter uses medium speed gearbox with low failure rate. Under the trend of wind turbines, semi direct drive technology may lead the development of wind power technology in the future. From the perspective of transmission system and maintenance, the speed of permanent magnet semi direct drive unit is between double fed and direct drive units, which combines the advantages of both. While meeting the transmission and load design, it has a more compact structure, light weight and low maintenance difficulty. According to the analysis, although the three wind power technologies can ensure the accuracy of cement strength inspection and experiment, and point out that the adaptability of cement production technology to the large-scale fan is different, it is obvious that the semi direct drive fan is more suitable for the large-scale fan requirements. Now that the semi direct drive technology is entering the era of large units, it will attract more enterprises to invest in research and development and mass production, which is also a technical trend that wind power lubricant suppliers should pay close attention to

technology + service, China's lubricant industry "Haifeng" is vigorous

over the past 30 years, from supporting imported wind turbines to escorting domestic wind turbines, shell, ExxonMobil, Castrol, Fuchs, great wall and other "main forces" in the lubricant industry have witnessed the development process of China's wind power industry from introduction and exploration to independent innovation, large-scale and efficient development, meeting the growing diversified needs of the industry at different stages, Constantly promote the innovation of products and services, and grow together with China's wind power industry by leading the breakthrough in the post wind power market

in this process, aiming at the pain points and difficulties of wind power operation and maintenance, China's lubricant industry has actively innovated the wind power operation and maintenance mode. Analysts in China's lubricant information industry said that whether it is the comprehensive management scheme based on the value of "lubrication economy" proposed by Mobil, the total cost of ownership management first proposed by shell, or the full range of solutions provided by Flowserve and great wall to customers, they all focus more on the overall lubrication management of the whole life cycle, and apply advanced lubrication technologies and solutions to help significantly improve the full life cycle value of mechanical equipment, Extend the service life of lubricating medium, reduce the probability of malignant mechanical accidents, and extend the use of equipment, so as to achieve energy conservation, emission reduction and efficiency increase

as the post market capacity of wind power increases year by year, major brands also actively continue to invest in the post market field, such as Mobil yushida offshore wind power service, which launched the industry's first offshore wind power oil tanker; Castrol teamed up with Onyx insight to "feel the pulse" of fan health through big data analysis; Shell upgraded and launched the "all-weather service 3.0" service package of wind power, and improved the efficiency of wind turbine management with the new platform of "shell Zhihui" lubrication management; Fuchs' one-stop efficient system scheme...

in 2020, the post operation and maintenance market of wind power is facing the transformation and challenge from "incremental market" to "stock market". In the face of the future transformation of the wind power operation and maintenance market, how to effectively grasp the overall development situation of the industry and make arrangements in advance for the new changes in market operation, so as to better serve China's wind power after-sales market in the "post subsidy" era, will be a common topic in the wind power lubrication industry. Industry experts said that informatization and digitalization will be decisive
