The tendons of a tension leg platform are critical structural components in maintaining the system integrity. A common tendon design limit is associated with the minimum tendon tension. Most TLP reliability studies in the past defined the minimum-tension limit state as the loss of tendon tension. However, studies have shown that temporary tension loss at a corner of a TLP will not necessarily jeopardize the system integrity if the tendon is allowed to stroke down during a loss of tension event. Hence, we define the limit state associated with minimum tension event as the down-stroke where the tendon unlatches itself. An approximate method is proposed in this study to evaluate the probability of tendon unlatching. Sensitivities to the key assumptions are also investigated.
