Abstract
Experiments with a cam-type clamp tool were carried out to overcome the difficulty of transporting and installing large-diameter mono-piles for offshore wind turbines. Using the experiments method to design a small wedge-type clamping mechanism and using cam teeth made of 40Cr material resulted in the maximum friction for the mechanism. A single clamping design was created for the cam-type clamp tool to hoist mono-piles for offshore wind turbines. Through force analysis and Automatic Dynamics Analysis of Mechanical System (ADAMS) dynamic simulation of the lifting tool, it was calculated that the clamping force of the lifting tool meets application requirements. A prototype was built in order to carry out an experiment in which the lifting tool hoisted a mono-pile. It was concluded from the experiment that the proposed design of the lifting tool is feasible in practical applications.
Highlights
In recent years, wind power has become the fastest developing new energy technology; it cannot be applied widely on land due to the fact that there is little space for wind farms and to the great noise produced when generating electricity [1]
Turbine structures can be categorized as mono-pile, gravity foundation, suction foundation, multi-pile foundation, floating foundation, etc
By pouring concrete caissons into the seabed, the gravity foundation method makes the whole turbine remain vertical using the gravity of the turbine, but subsea operations indicate that the overall cost is high, and this method is limited to applications in shallow water [7]
Summary
Wind power has become the fastest developing new energy technology; it cannot be applied widely on land due to the fact that there is little space for wind farms and to the great noise produced when generating electricity [1].
