Mooring Chain Fatigue
摘要
Out of Plane Bending (OPB) can occur in links at the connection between mooring lines and the moored floater where adjacent chain links have relative angular movement, refer to Fig. 9.1. Those links are subject to bending induced stress in addition to tension-tension stress, which should be included in the fatigue assessment. This chapter provides informative guidance on the assessment of OPB fatigue calculations.
