This is the second of two companion papers intending to summarize and pointing out some of the main engineering achievements obtained through a continuous cooperative research effort, jointly conducted by Industry and University. Part Ⅰ covered Riser Mechanics and design issues. Part Ⅱ is dedicated to Riser Loading and Dynamic Positioning. In Part Ⅰ (Pesce et al., 2003), SCR dynamics, touch down point dynamic interaction loading, catenary riser dynamic compression under twist, risers and umbilical cables structural mechanics, were treated and modeled through analytical and numerical methods. SCR design issues and fatigue assessment of flexible pipes were also addressed. In this second paper, Part Ⅱ, VIV, extreme dynamic loading, nonlinear dynamics of FPSOs and turret positioning are presented. Nonlinear control techniques are addressed aiming to optimize FPSO heading, constrained to a cost function that takes into account risers loading, mooring tension, roll motion and fuel consumption.
