Abstract: SUMMARYThis work presents the implementation of optimized numerical tools for the coupled analysis of floating platforms for offshore oil exploitation. The focus is on time-domain, nonlinear dynamic analysis, considering the coupling between the hydrodynamic behaviour of the hull and the structural behaviour of the mooring lines and risers modelled by finite elements (FEs). Some aspects of the formulation and solution of the large-amplitude equations of motion of the hull of the platform are presented, includi… Show more

“…Implicit algorithms, such as the trapezoidal rule (γ = 0.5, β = 0.25), are better for inertial problems, where the dynamic response is dominated by mode shapes with higher period values. Explicit algorithms such as the central difference method (γ = 0.5, β = 0) are more adequate for transient problems [119]. Explicit methods calculate the state of a system at time t n+1 from the state of the system at the time t n , while implicit methods use the state of the system at t n and t n+1 .…”
