Abstract EN
The use of powerful numerical tools based on the finite-element method has been improving the prediction of the holding capacity of fixed anchors employed by the offshore oil industry.
One of the main achievements of these tools is the reduction of the uncertainty related to the holding capacity calculation of these anchors.
Therefore, it is also possible to reduce the values of the associated design safety factors, which have been calibrated relying on models with higher uncertainty, without impairing the original level of structural safety.
This paper presents a study on the calibration of reliability-based safety factors for the design of torpedo anchors considering the statistical model uncertainty evaluated using results from experimental tests and their correspondent finite-element-based numerical predictions.
Both working stress design (WSD) and load and resistance factors design (LRFD) design methodologies are investigated.
Considering the WSD design methodology, the single safety is considerably lower than the value typically employed in the design of torpedo anchors.
Moreover, a LRFD design code format for torpedo anchors is more appropriate since it leads to designs having less-scattered safety levels around the target value.
