The work presented in this talk fits into a global collaborative R&D program between SEAL Engineering (Technip subsidiary) on the one hand and both, the laboratory of Modeling in Mechanics of Marseille (the M2P2, Ecole Centrale Marseille) and the Institut Pprime of Poitiers on the other hand. It more particularly fits into the frame of an international collaborative numerical benchmark for high Reynolds which is subjected to a special session at the OMAE2016. As requested for the benchmark, the efforts have been spent onto the CFD modelling of the high Reynolds flow that develops over a square rounded shape cylinder. The proposed analysis follows the one already presented in Nantes at the OMAE2013, refer to OMAE2013-10200 and which highlighted very encouraging comparisons for ‘relatively high’ Reynolds conditions (Re=22000). The ‘in-house’ CFD capabilities are, for the proposed work, used to increase the investigated Reynolds range up to reach flow regime representative of full scale offshore conditions (i.e. Re=10 7 ).
