... weight on deck, as well as environmental loads (wind gusts and waves), calculated as per (DNVGL-RP-C205, 2014). Numerical simulations were performed to assess safety factors of operation, considering the 120 klbf weight-on-deck reported on the safety alert (BSEE, 2022). Operation was found to be safe...

... dimensioned, with minimum fatigue life, with a safety factor of 10, to be more than 600 years. For the BSRs, the minimum fatigue life, with a safety factor of 10, was found to be more than 100 years. Based on the results above, considering umbilicals and related equipment, the minimum fatigue life found...

... and in particular on laboratory specimens and small-scaled connectors. Based on these last structural tests, a safety factor of almost 8 was obtained for the design method on small-scaled connectors. Prototype tests at scale 1:1 allowed the methodology to be fully validated and a new product to be qualified...

The objective of the NorMoor JIP has therefore been to provide a more consistent analysis methodology, and calibrated safety factors for time domain in line with this methodology. This is achieved through reliability-based calibration...

Thus, there is a need for a mooring design code with a consistent analysis methodology and with safety factors for time domain analysis that are in line with this methodology and calibrated at an appropriate target reliability level. This is achieved through reliability-based...

The intrinsic conservatism carried by design codes may not only lead to higher fabrication/installation costs, but also conflict with the operational limits of existing installation vessels. Based on the analysis of four design cases, it is argued that ISO/API safety factors...
