Recently, a new technology, “Grouting Cabin Structure of a Grouted Connection in a Foundation of an Offshore Wind Turbine Generator”, developed by New Energy Engineering Design Institute under POWERCHINA HUADONG was granted the United States Patent for Invention. This is the company’s first international patent granted by Euramerican developed countries, showing the company’s technological innovative ability in offshore wind power sector.

Introduction of the Patent: the structures for foundations of offshore wind turbine generators usually employ grouted connections, but the stress mode is “passive”. In order to solve this problem, the technology, by arranging a grouting cabin structure at the grouted connection section and by means of grouting and pressurized grouting, provides an active force for the grouted connection section to improve its bearing capacity.
