Pitch motion reduction of a barge-type floating offshore wind turbine substructure using a bidirectional tuned liquid damper

초록

This paper aimed to examine the effects of a bidirectional tuned liquid damper on the stability of a barge-type floating offshore wind turbine. This analysis considered the pitch-induced external moment resulting from wave action and the sloshing effect on a bidirectional tuned liquid damper. Bidirectional tuned liquid damper geometries with different baffle heights at the middle of the bidirectional tuned liquid damper were examined and the pitch motion of the floating offshore wind turbine integrated with the bidirectional tuned liquid damper was considered to determine the optimal bidirectional tuned liquid damper configuration. Based on the wave period optimizing the bidirectional tuned liquid damper may reduce the pitch motion of a barge-type floating offshore wind turbine by 10%–30%. © 2024 Elsevier Ltd
