Wind turbine generators gently turn in the sea wind, like rows of windmills. The wind turbine is composed of the upper wind generator and the lower jacket foundation. To make the wind turbine stand firmly in the deep sea, the jacket foundation is reshaped into a tri-suction-pile jacket foundation. Then how are huge wind turbines installed at sea? What kind of device plays an important role in the process? CCCC has independently developed the automated triangular hanging beam, which not only is much lighter than the conventional one but also can hold the jacket foundation quickly and automatically, creating the fastest time record of 10 hours for the construction of a single jacket foundation.
