5. China Power Construction: "Guoxuan" modified wind power installation platform will be put into production soon

On August 15, after successfully completing various renovation projects, the "Guoxuan" platform left Weihai Jinling and went to Yangjiang, Guangdong for wind power installation. According to the plan, the "Guoxuan" platform will arrive in the construction area and put into production in the near future.

The "Guoxuan" platform was originally a CJ46 jack-up drilling platform, which is mainly composed of a triangular main platform, an X-Y cantilever beam, a drilling system and three open truss-type legs. The total length is 65.25 meters, the width is 62 meters, the depth is 8 meters, the leg length is 153.8 meters, the operating water depth is 114.3 meters, and the maximum drilling depth can reach 9144 meters.

In addition to the "Guoxuan" platform, the "Guoxin", another jack-up drilling platform of Guizhou Power Construction, is also undergoing renovation and upgrading. The “Guoxin” ship is JU2000E, with a total length of 70 meters, a width of 76 meters, a depth of 9.45 meters, and a maximum operating depth of 122 meters.

It is said that after the two platforms are refitted, they will go to Yangjiang, Guangdong for wind power installation, which can meet the tower installation, main engine installation, hub, single blade installation, and impeller assembly installation of the Yangjiang Qingzhou Three 500 MW offshore wind farm.

6. Jiangsu large-scale offshore wind power grid-connected power transmission project has entered the "sprint stage"

Recently, the construction of the main part of the main part of the Jiangsu Coastal Second Corridor, a large-scale offshore wind power grid-connected power transmission project across the country, has been completed. Jiangsu is rich in tidal flat resources and offshore wind energy resources, and has the largest offshore wind power base in the country. It is estimated that the total installed offshore wind power capacity will exceed 10 million kilowatts this year.

The Jiangsu Coastal Second Channel Project includes three 500kV substations in Tonghai, Sheyang, and Fenghai, and three 500kV double-circuit transmission lines, which constitute the "three-transformation and three-line" clean energy "main artery" along the coast of Jiangsu, with a total length of 350 kilometers. "

After the coastal second channel project is put into operation, it will provide a green channel for Jiangsu's new energy consumption and load deployment." The completion of this channel can increase the offshore wind power transmission capacity by approximately 6.4 million kilowatts, and it is expected to reduce the emission of carbon dioxide by 17.6 million tons per year. 318,000 tons of pollutants such as nitrogen oxides and sulfur dioxide were discharged. The project is expected to be completed and put into operation in November this year, and will meet the needs of Jiangsu's "North-South Power Transmission" and the Northwestern clean energy into the Soviet Union.

7. Sweden's newly planned offshore wind farm, all using 20MW+ wind turbines

Recently, Zephyr Vind, headquartered in Sweden, announced a plan to build a large offshore wind farm in Sweden. The wind farm is called Poseidon and will use both floating and fixed foundations.

The Poseidon offshore wind farm, located in the waters between Sweden and Denmark, about 40 kilometers northwest of Gothenburg, will consist of two sites-Poseidon Nord and Poseidon Syd. It covers an area of 162 square kilometers and 35 square kilometers respectively. The site selection is mainly based on the abundance of wind resources and the convenience of grid access.

The Poseidon North site is located in a deep water area, and the developer chose to use a floating foundation in this area, while the Poseidon South site has a shallower water depth and will use a fixed foundation. Two design schemes are currently proposed: Scheme 1: Arrange 61 wind turbines with a single unit capacity of more than 20MW, blade tip height of 340 meters, and impeller diameter up to 310 meters; Scheme 2: Arrange 94 wind turbines with a stand-alone capacity of 15MW and blade tip height of 260 Meters, the impeller diameter is 230 meters.

The total installed capacity of the project is estimated to be about 1.4GW, and the annual power generation capacity is 5.5 billion kWh, which is equivalent to the annual electricity consumption of 1 million households.

9. WoodMac: Wind turbine prices are expected to increase by 10% in the next 12-18 months

In the past six months, the prices of bulk commodities such as steel, copper and aluminum, as well as the increase in carbon fiber prices, coupled with a four-fold increase in logistics costs, have continuously pushed up the price of wind turbines. According to WoodMac's forecast, under the influence of commodity prices, logistics costs and the new crown epidemic, the price of wind turbines is expected to rise by 10% in the next 12 to 18 months, and this trend will continue at least until the 3-4 quarters of 2022.

But WoodMac also said that despite the increase in costs, it is expected that wind turbine prices will return to normal levels by the end of 2022.
