Simulation and Experimental Study of A TLP Type Floating Wind Turbine with Spoke Platform

Abstract

As the demand for renewable energy has increased following the worldwide agreement to act against global climate change and disaster, large-scale floating offshore wind systems have become a more viable solution. However, the cost of the whole system is still too high for practical realization. To make the cost of a floating wind system be more economical, a new concept of tension leg platform (TLP) type ocean floating wind system has been developed. To verify the performance of a 5-MW TLP type ocean floating wind power system designed by the Korea Advanced Institute of Science and Technology, the FAST simulation developed by the National Renewable Energy Laboratory is used. Further, 1/50 scale model tests have been carried out in the ocean engineering tank of the Research Institute of Medium and Small Shipbuilding, Korea. This paper compares the simulation and ocean engineering tank test results on motion prediction and tension assessment of the TLP anchor.

Motion Analysis of A Wind-Wave Energy TLP Platform Considering Second-order Wave Forces

“…In addition, when a large-scale offshore wind farm is constructed, the installation area of mooring lines is smaller than that of catenary mooring lines because they are installed vertically downward, causing less interference with nearby structures or maritime fishing activities. Therefore, various studies have been conducted worldwide on TLP-type offshore wind turbine platforms (Adam et al, 2014;Kim et al, 2016;Chung et al, 2021;Ren et al, 2022). A previous study reported that the TLP platforms are economical because their life-cycle cost (LCC) is relatively lower than that of Spar plftforms (Pantusa et al, 2020).…”
