Sažetak
A new stiffness matrix for nonlinear dynamic analysis of triangular TLPs is formulated utilising both the equilibrium of forces and energy balance approach for arbitrary surge, sway and yaw. Static numerical analysis is performed for a triangular TLP, ordinarily used as a benchmark in the relevant literature, by imposing surge force and yaw moment. In order to validate the new stiffness formulation, the obtained results are compared with those determined by an FEM analysis. Some shortcomings of the traditionally used stiffness matrix are pointed out.
