5. Mooring Line Components (Section 6)

a) Studless Chains (R3, R4, R5 grades)

• Minimum safety factor on chain breaking load: 1.67 (for L2 consequence) after applying load factors.
• Wear allowance: reduce diameter by 5-10% over design life.
• Fatigue: Use S-N curves from API RP 2SK (Appendix A) for chain links. Note that chain-peak bending at fairleads and chain stoppers is a known failure mode.

However, flexible pipe systems also present several challenges, including:

It specifically addresses thermal (fire) and pressure (blast) loads that exceed normal operating conditions. Asset Lifecycle: api rp 2fb pdf new

Step C – Apply LRFD:
(\gamma_E = 1.30), characteristic tension = (1.30 \times 850 = 1105) kN.
Polyester MBL = 2500 kN. (\gamma_m = 1.80) (L2 consequence).
Design resistance = (2500 / 1.80 = 1389) kN.
Check: (1105 \leq 1389) → OK.
