Project

The Greater Changhua Offshore Wind Farms are a series of offshore wind farms off the coast of Changhua County, Taiwan. Upon completion, the four Greater Changhua offshore wind farms together form Taiwan’s largest wind power complex, which can power approximately 2.8 million Taiwanese households.

The Greater Changhua offshore wind farm projects are being developed at four sites in the Taiwan Strait, approximately 35 km to 60 km offshore Changhua County in Taiwan. The total power generation capacity of the wind farms is 2.4GW. The proposed wind farms consist of four wind farms, which are Changhua 1, Changhua 2A, Changhua 2B, and Changhua 4. Changhua 1 has a capacity of 605 MW and will be located in a water depth of 34.4–44.1 meters across an area of 108.7 km2. Changhua 2 has a capacity of 295 MW.

CNI has a proven track record as a contractor for fabricating and installing oversized steel structures, serving both offshore and onshore projects. Our expertise extends to a wide range of structures, including but not limited to offshore modules and onshore industrial facilities. Our state-of-the-art facilities, advanced fabrication techniques, and skilled workforce enable us to deliver customized solutions that meet the most demanding project needs while adhering to rigorous quality standards and regulatory requirements. Oversized steel structures refer to large-scale steel components or assemblies that exceed standard size specifications. These structures are characterized by their substantial dimensions and are often used in industrial, commercial, and infrastructure projects where strength, stability, and durability are paramount. Fabricated from high-quality steel materials, oversized steel structures can include beams, columns, trusses, frames, and other elements tailored to accommodate specific design requirements and engineering specifications.

Tubular Members are integral components of offshore structures, which are essential for supporting offshore platforms in marine environments. These members consist of cylindrical or tubular steel sections that form the framework of the structure, providing strength, stability, and load-bearing capacity. Tubular members are designed to withstand the harsh conditions of the offshore environment, including wave action, wind loads, and corrosion. They are typically fabricated from high-strength steel alloys to ensure structural integrity and longevity. Tubular members are interconnected using various welding techniques to create a robust and durable offshore structure capable of withstanding the forces exerted by ocean currents and environmental factors.
