The paper investigates hydrodynamical aspects of a 2-body, floating offshore production system for benign environments. The main focus is on the following issues: 1. Comparison of multiple body and single body hydrodynamical coefficients. 2. Mesh size requirements, computer run times and convergence of multiple body computations. The overall importance of the hydrodynamical interaction for the motion response of the two bodies is discussed in some detail, and it is documented how neglect of the fluid coupling effect may lead to erroneous and some times unconservative predictions.
