World-leading Wind Turbine Manufacturer Saves CNY 900,000 on Hybrid Tower Project - 1

CASE STUDY ^ Bentley Advancing Infrastructure Project Summary Organization: Xinjiang Goldwind Science & Technology, Co., Ltd. Solution: Structures Location: Dezhou, Shandong, China Project Objective: • Develop an integrated steel and cement hybrid tower design for wind turbine generators operating in low-wind areas. • Implement a BIM strategy to achieve collaborative design, multi-discipline model review, and construction simulation. Products Used: ProStructures, RAM, STAAD.Pro World-leading Wind Turbine Manufacturer Saves CNY 900,000 on Hybrid Tower Project ProStructures and STAAD.Pro® Integration Cuts Goldwind's Research and Development Time by 35 Percent Fast Facts • Goldwind is the world's leading manufacturer of wind turbine generators, with more than 38 gigawatts of capacity worldwide. • This research and development initiative delivered a hybrid tower design that increases the utilization rate for wind energy by 23 percent. Bentley's design and analysis applications saved the project team more than 400 resource hours during development. Integration between ProStructures and STAAD.Pro enabled an iterative design and analysis process that reduced modeling time by 35 percent, resulting in a savings of CNY 900,000. Interoperability with models from other software applications in related disciplines reduced design coordination time. Innovation Drives Product Research and Development Headquartered in Beijing, China, Xinjiang Goldwind Science & Technology Co., Ltd. (Goldwind) is a global wind energy solutions provider responsible for 12 percent of newly installed capacity worldwide. The company achieved its position as the number one international wind turbine manufacturer with a unique business model that spans the whole product lifecycle. Goldwind's commitment begins with research, development, and manufacturing and continues through investment, sales, and service. This commitment produces wind energy solutions such as the recently developed hybrid tower for use in low-wind areas. The innovative design increases the utilization rate for wind energy by 23 percent. Goldwind's research and development team used Bentley's structural analysis and detailing applications to develop the tower with a cement base and steel upper section. As a result of the technology integration, the team shortened design time by 35 percent, resulting in a savings of CNY 900,000. Optimized Low-wind Turbine In 2016, Goldwind held 27 percent of Chinas market share for newly installed capacity, making the company the largest wind turbine generator manufacturer in the country for the sixth consecutive year. Goldwind continuously upgrades its product line through technical innovation to meet market demand. This demand is fueled by China's 13th Five Year Plan (FYP), which set a nationwide target of 250 gigawatts of cumulative connected wind capacity by the end of 2020. For this project in Dezhou, Shandong, China, the hybrid steel and concrete tower was designed to make the wind turbine more effective in low-wind areas. The complex implementation process for the CNY 1 million project prompted Goldwind to adopt a BIM strategy. The hybrid tower project involved multiple participants and stakeholders, including managers, designers, contractors, vendors, and subcontractors. Familiarity with the new product development process varied widely among this audience. Using BIM technology allowed the project team to provide transparency enabling collaborative design, multi-discipline model review, and construction simulation. Integrated Modeling and Analysis The project team implemented Bentley's BIM advancements including ProStructures for steel and concrete design, STAAD.Pro for 3D structural analysis and design, and RAM® for load calculation. These interoperable applications allowed the team to assemble 3D design models for each discipline, then use the models to calculate quantities and statistics. Goldwind performed comprehensive collision detection for the multi-discipline models both jointly and separately, and made any necessary design changes. A construction simulation and animation provided insight and direction to the contractors. To meet China’s target of250 gigawatts of cumulative connected wind capacity in three years, Goldwind used Bentley software to develop a tower generator that increases the efficacy of wind turbines in low-wind areas. Bentley's integrated applications provided the solutions necessary to resolve issues that arose during the project. Goldwind used the interface between ProStructures and STAAD.Pro to shift from modeling to structural analysis and then back again. Model information passed seamlessly between the 3D design applications, allowing the team to analyze and compare different structural designs. Goldwind used RAM and data from STAAD to analyze a wide range of loading conditions.
