ZTT Powers the World's Largest Single-unit Floating Wind Turbine — "Mingyang Tiancheng"

On December 11, 2024, the world's largest single-unit floating wind turbine, the 16.6MW "Mingyang Tiancheng", officially connected to the grid, marking a monumental achievement in renewable energy. ZTT was entrusted with the project's most critical component: the design, delivery, construction, and installation of all dynamic submarine cables and accessories. ZTT's technical expertise ensured the seamless grid connection and reliable power generation of this groundbreaking floating wind platform.

The Mingyang Tiancheng features a revolutionary "V" configuration and a turbine foundation capable of significant offset and 360° rotation, challenging traditional submarine cable design and installation practices. ZTT conducted comprehensive simulation analyses to address these complexities and developed a bespoke 35kV dynamic submarine cable system. This included a meticulously optimized laying plan to accommodate the unique movement of the dynamic foundation.

The project's execution showcased ZTT's unparalleled technical competency. The Yuanwei construction team deployed Dynamic Positioning (DP) diving systems, ROV (Remotely Operated Vehicle) underwater robots, and advanced pre-installation techniques for accessories. These innovations enabled efficient and precise submarine cable installation within a narrow operational window. Following completion, the system faced its ultimate test when Super Typhoon Yagi struck the region. The cables remained intact, and their line shape and performance exceeded expectations, affirming ZTT's engineering excellence.

This achievement testifies to ZTT's position at the forefront of dynamic submarine cable technology. It demonstrates the company's readiness to meet and exceed the demands of even more challenging global projects, cementing its reputation as a trusted leader in marine energy solutions.

With over ten global demonstration projects in marine energy development and dynamic submarine cable applications, ZTT continues to set benchmarks in the floating wind power industry. By combining innovation and precision, the company is driving advancements in deep-sea, large-scale floating offshore wind power solutions, supporting the global transition to sustainable energy.
