Extended TLP (ETLP) performance in marine environmental conditions. Both platforms have
12 tethers installed in a water depth of 700 m located in the Caspian Sea under irregular
JONSWAP waves, wind and current loads. A coupled BEM-FEM numerical time and
frequency domain analysis was performed to estimate motions and mooring line cumulative
fatigue damage of two kinds of tension leg platforms. Besides, power spectra density (PSD) …
