BHFM

Hydrodynamic benchmark for fixed offshore wind turbine sub-structures

Duration: 0.5 year

Project description

This project aims to benchmark the hydrodynamic methods currently used to simulate the structural behaviour of the foundations of massive offshore tripod and gravity-type wind turbines supporting high-powered wind turbines (5 MW). The aim is to identify the physical phenomena to be modelled, and the numerical tools to take them into account by offering the best compromise between precision and computation time.
BHFM aims to simulate a set of loading cases for gravity and tripod foundations. Since the tripod foundations are made of steel and the gravity foundations of reinforced concrete, structural simulation tools adapted to each of the foundations will be used. The work will focus on parametric sensitivity studies to understand the impact of hydrodynamic modelling on the structural response of massive foundations.

Objective

  • Identifying the impact of hydrodynamic modelling on the structural behaviour of massive foundations of tripod and gravity offshore wind turbines, particularly in cases of highly arched swells.
