120% factor when designing mooring line chain minimum breaking load?

Are mooring line connections to FPSO, anchor piles or between chain-wire segments (including shackles or H-links) designed for chain minimum breaking load of 120%?

The 120% of chain minimum breaking load requirement only applies to the design of the fairlead, chain stopper, and anchor pile. This requirement does not apply to the shackles or H-links linking the different segments of the mooring chains. Please note that shackles or H-links designed to 120% of chain minimum breaking load might not fit geometrically due to their oversize. The objective of the 120% requirement is that in case of a mooring line failure the connections to the FPSO and mooring pile shall be undamaged such a new mooring leg can be installed without repair. Hope that helps.
