GENMA 3000t Floating Crane Powers Hainan CZ2 Offshore Wind Project

A key clean energy project of the Hainan Free Trade Port, the Hainan CZ2 Offshore Wind Demonstration Project (Phase II) has now installed over 20 large-diameter steel piles.

The 1.2 GW project will generate about 3.7 billion kWh of clean electricity annually. Each monopile is 96 meters long and weighs nearly 1,900 tons — demanding extreme precision.

At the heart of this operation is the heavy-lift vessel "Tianfeng 10" and its onboard GENMA 3000t floating heavy lift crane.

Built by Nantong Rainbow Offshore, "Tianfeng 10" is 149.8 meters long, equipped with DP2 dynamic positioning, and delivered in 2023. The GENMA 3000t crane — independently designed and manufactured by Nantong Rainbow Heavy Machineries — delivers 3,000t lifting capacity and 110m hoisting height, with full luffing and 360° continuous slewing. It was named a Jiangsu "First Set Major Equipment" in 2024.

"Tianfeng 10" has already served multiple offshore wind projects across China, including Danzhou, Yangjiang, and Lingao. Its continued performance at CZ2 confirms the reliability of the GENMA 3000t floating crane for large-scale monopile installation.

As the project moves forward, GENMA stays committed to supporting the offshore wind industry with proven equipment and expertise.
