The structural response was evaluated through finite element analyses that reproduced the interaction between the core and the FRP layers. This study discusses the design extreme loads assessment, the finite element modeling of the blades, and the related strength criteria to be considered. ? 2019 by the International Society of Offshore and Polar Engineers (ISOPE).Arctic engineeringFiber reinforced plasticsFinite element methodOcean currentsTurbine componentsAbnormal conditionsCurrent turbinesFiber reinforced plastic(FRP)FRP BladeRoot ConnectionStrength criteriaStructural responseUltimate strengthTurbomachine blades[SDGs]SDG7conference paper2-s2.0-85078867598
