Figure 12 : Submodel, using the Springs Formulation, of the bottom of the MC column.

Fig. 12 confirms that the higher stresses are located at the bottom of the MC column. The highlighted points have the following magnitudes:

 S1: 14 061 MPa  T1: 565.26 MPa  U1: 2 373 MPa  V1: 376.87 MPa  W1: 4 141 MPa

Final Platform As the original DeepCWind structure proved to be unable to cope with the applied stresses, a structural improvement was performed and is suggested here. This reinforcement consisted of using structural reinforcements, as well as adjusting the members’ thicknesses.
