Two homegrown fourth-generation wind turbine installation vessels, the latest generation in the world, have been delivered in Nantong City of east China's Jiangsu Province. The vessels boast strong resistance to wind and waves and offer a 30-percent increase in installation speed compared with the third generation. As the country's fourth-generation self-propelled vessels, they are designed for installing offshore wind turbines with significantly enhanced operational flexibility and efficiency. The delivery marks a major step forward in China's capabilities for developing offshore wind farms.
