Although engineers often assume that waves and currents are collinear,they propagate in different (unparallel) directions, i.e. the incomingangle between waves and currents is not generally zero or 180° inreality. This paper makes a special effort to investigate how thedifferent incoming directions affect motions of a Truss SPAR platform.In order to achieve this, the six degrees of freedom motion of theplatform is considered with the wave and current loads evaluated by aslender body formulation. Various cases with different wave andcurrent parameters are calculated and the effects of waves and currentson mean offset and oscillation motions of Truss SPAR are investigated.
