Mooring Line Safety Factor
Safety factor (MBL / working load) for a mooring line; OCIMF MEG4 requires SDMBL ≥ 125 % of expected peak load.
Safety factor
2.67 -
Utilisation of MBL
37.5%
Status
OK - OCIMF MEG4 healthy
Formula, assumptions, and limits
$$SF = \frac{MBL}{F_\text{working}}$$
OCIMF MEG4 uses Ship Design Minimum Breaking Load (SDMBL) = 100 %; Line Design Break Force (LDBF) = 125 % SDMBL; Tail Design Break Force (TDBF) = 137 % SDMBL. Brakes set at 60 % SDMBL.
