April 16, 2024 Last week, the Hai Long Offshore Wind Project announced the official launch of offshore construction. TWD , a leading engineering company in the offshore wind market, 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 vessel.
Pre piling template
TWD was responsible for designing the majority of the pin pile installation equipment on the heavy lift vessel Green Jade. TWD’s significant contribution was the design of a subsea self leveling pre piling template, ensuring precise and efficient pile plac ement on the seabed. The template adjusts its position to align with seabed contours, guaranteeing vertical installation. This template is currently the largest and most complex of its kind in the offshore wind industry. Furthermore, TW D was also involved in the design of the impact hammer and follower seafastening.
Seafastening
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.
Dynamic pile sway analyses
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. This analysis helped evaluate the feasibility and workability of several concepts and pile installation methodologies, ultimately leading to the selection of the best concept in collabora tion with CDWE.
Thijs Roethof, Country Manager Taiwan at TWD, is enthusiastic about TWD’s contribution to the Hai Long Project: “As we embark on the offshore construction phase of the Hai Long Offshore Wind Farm, TWD is proud to have been trusted with the design of the pi n pile installation equipment for the Green Jade vessel. Our tailored solutions, including the largest and most complex pre piling template of its kind, reflect our innovation and expertise in the offshore wind industry. We are excited to see our designs i n action, contributing to the successful installation of what will be the largest offshore wind project in Taiwan.”
The launch of offshore construction marks a significant milestone for the Hai Long Offshore Wind Project, and TWD’s innovative design of the piling template underscores its drive to deliver state of the art solutions for offshore projects with challenging conditions.
