Original paper


A novel concept of incorporating a heat exchanger system in an offshore wind turbine-monopile foundation and its effect on the stress–strain response of pile are investigated in the present work. Thermo-mechanical analysis of the steel monopile with fluid carrying pipes is carried out using finite element method through heat flow and structural analyses. The effect of thermal loading–unloading cycle on the pile, the temperature distribution in the pile and soil, resultant pore pressure development in the soil, the axial stress and strain in the pile and the shear stresses in soil are studied. The thermal stresses and displacement of the piles are checked against the serviceability limits for the offshore structure.
