14. Made in China for the world's first zero-subsidy offshore wind farm put into production

Following the zero subsidy for onshore wind power, when to achieve zero subsidy for offshore wind power has also become the focus of attention of all parties. The world's first zero-subsidy wind farm Hollandse Kust Zuid (hereinafter referred to as HKZ) is about to be built by the Swedish Vattenfall Waterfall Group at the forefront. The total planned installed capacity of the HKZ wind farm is 1.5GW, using 140 Siemens Gamesa 11MW wind turbines. It is expected to be fully operational in 2023. This will become the world's first "zero subsidy" offshore wind farm to be put into operation, and it will also be the world's largest offshore wind farm.

In mid-to-late June, the current 71 sets of tower flanges of the project have begun to be sent from Elite to major tower factories in Europe. This is also the 10 MW+ wind power flange we have undertaken again after Dongqi’s 10 MW, Haizhuang 10 MW, and a foreign 12 MW, 14 MW model.

The height of the 11MW wind turbine used in HKZ wind farm is 230-250 meters, and the swept area generated by the rotating diameter of the 200-meter blades reaches an astonishing 30,000 square meters, which is equivalent to an area of 45 acres of land. The blades rotate six to eight times per minute, and the top speed of the blade tip exceeds 300 kilometers per hour, which is equivalent to the speed of China's high-speed rail.

16. The world's first floating wind power design software was officially developed

A few days ago, a group composed of developers, engineering companies, software companies, and universities has developed the world's first software specifically designed for floating wind power underwater systems.

Companies and institutions participating in the project include: French floating wind power developer EOLFI, which has been acquired by Shell, renewable energy engineering consulting company Innosea, which has signed a cooperation agreement with Shanghai Kan Institute, American electrical engineering and digital simulation consulting company Capsim, and software companies AbyssCAD, Nantes Central Institute of Technology, France.

In the past, the design of floating wind power, whether it was foundation, mooring or cable, borrowed a full set of mature software from the offshore oil and gas industry. But in fact, the coupled loads and common water depths of floating platforms are far from those of offshore oil and gas platforms; and each part of the content is designed with independent software, and the basic assumptions and simulation models of each software are different, and the overall motion performance of the final piece. It may be different from the design value.

Nowadays, floating wind power has a special software called STATIONIS, which can provide optimized solutions for mooring systems and array dynamic cables. The software improves the design quality of floating wind farms from the perspective of technology, cost and risk. It can help developers make decisions for floating wind power projects of any scale and type at any stage.

17. Denmark designed a new generation of 14MW offshore wind power installation vessel

The Danish design company Knud E. Hansen (KEH) has launched a new "Atlas A"-class jack-up offshore wind power installation vessel design scheme, which can carry 4 new generation 14 MW wind turbines. This wind power installation vessel is mainly used for "large offshore wind turbines". The cost-effective installation scheme.

The "Atlas A" class is specially tailored for the installation of large offshore wind turbines. It is designed on a pre-installed basis for transportation and assembly of large wind turbines. It is cost-effective and efficient. "Atlas A" class can choose 1600-2500 tons of cranes. Compared with the traditional design scheme, the ship type has the characteristics of highly customizable, and the crane, propeller, generator and lifting system can be selected according to the needs of customers.

This type of ship optimizes energy consumption, and the ship can be powered by batteries when berthing. When the pile legs are falling, about 60% of the energy can be recovered. In addition, the rack and pinion design of the lifting system can carry 5000 cycles to ensure that the legs and parts can withstand wear during the ship's operating cycle and reduce replacement.

Main parameters: ship length: 155.4m ship width: 57.4m main deck height: 12.5 m
