Twin-shaft batch mixers for Vietnam’s first offshore windfarm project

August 2020
Bac Liêu Province Wind Power Plant in Vietnam is Asia’s first large-scale coastal wind energy project. Operating since 2013, it is being expanded continuously. During the current third expansion phase, 71 turbines are being constructed. The challenge of this project can literally be found at the bottom of the sea: the cement bases for the wind turbines cannot simply be produced on land and then placed in the ocean. Instead, they have to be poured directly into the ground, using a floating platform. To this end, a mobile batching plant was installed on a dredge. At its heart are two twin-shaft batch mixers from BHS.
