Core Viewpoint - Shandong Energy Group has initiated the development of the Bohai Zhonghai Offshore Wind Power A site to enhance electricity supply in Shandong Province, marking a significant step in China's transition to cost-effective offshore wind energy [1][3]. Group 1: Project Overview - The wind farm consists of 60 turbines with a total installed capacity of 500,000 kilowatts and a single turbine capacity of 8.35 megawatts [1]. - It is the first grid-parity offshore wind project in Shandong Province and the first approved project in China's offshore wind sector to enter the grid-parity era [1]. - The project is expected to save 519,000 tons of standard coal and reduce carbon dioxide emissions by approximately 1.26 million tons annually [1]. Group 2: Development Challenges - The project faced significant challenges, including complex hydrological and geological conditions affecting foundation design and construction [3]. - Cost optimization strategies were necessary, including the optimization of submarine cable routing and the layout of offshore substations to reduce costs [3]. Group 3: Technological Innovations - The project team utilized digital twin technology through Bentley applications to enhance planning and visualization, creating a digital twin model for the project [4][5]. - Advanced digital tools were developed to optimize the submarine cable collection line, improving efficiency and reducing costs [5]. Group 4: Efficiency Improvements - The use of three-dimensional design increased project design efficiency by 30% and shortened construction time by 20% [6]. - The project achieved a record of planning, approval, construction, grid connection, and operational effectiveness all within the same year [6].
