Overview

Randomized trial evaluates structural types for wind turbine support, highlighting optimal design configurations.

Key Points

  • This research aims to compare different jacket foundations for supporting deep-sea wind turbines and determine the most effective design.
  • Evaluated three-pile, four-pile, and five-pile jacket foundations using SACS software.
  • Analyzed performance metrics including static stress, modal frequency, and fatigue damage.
  • Conducted analysis in around 50 m deep waters at the Huadian Yangjiang Qingzhou 3 Offshore Wind Farm.
  • The four-pile jacket optimizes load distribution, reducing maximum pile head load by 33% compared to three-pile.
  • Fatigue damage increases with pile number, with five-pile showing the highest fatigue metrics.
  • The four-pile jacket has the lowest steel weight at 2054.33 tonnes, being more economical than the other designs.
