Wind Energy – Pin Pile Installation
Dutch engineering company TWD was awarded the tailored design of the pin pile installation equipment by CSBC DEME Wind Engineering (CDWE). TWD’s tailored designs will play a key role in the installation process of Hai Long, with a capacity exceeding 1 GW, with the Green Jade.
In addition, TWD took on the design for the pin pile seafastening, with three sets of four piles stacked vertically, each with its own upending hinge.
This design enabled secure and efficient transportation and installation of the pin piles. Moreover, TWD was also involved in the design of the impact hammer seafastening.
The challenging installation conditions, characterized by deep waters, long pin piles, and heavy hammers, posed significant technical challenges. To address these challenges, TWD conducted extensive dynamic pile sway analyses during the concept definition phase to determine the minimum requirements for the piling template.
