The TLP motions in designed sea states were simulated and tendon tension time history results were obtained with various pile installation errors to investigate the relation between installation error and tendon tension. The corrections about tendon tension were decided by the relation between installation error and tendon tension. The tendon strength was analyzed by considering the tendon pile installation error corrections. The results showed that it is necessary to consider pile installation corrections when calculating tendon tension in global performance analysis and performing tendon strength analysis.
