| dc.description.abstract | Available literature on offshore mooring is very scattered, unorganized, and available codes and guidelines are very conservative while determining design parameters, such corrosion rate, fatigue factor etc. Mooring design can be optimized by use of more precise design parameters which are based on proven research, field study. Inspection data etc. A study of various design parameters involved in offshore mooring design available from conducted research etc. and comparison with codes, standard and guides. Fatigue failure are one of the critical failure modes. Traditionally only mooring tension are considered in the mooring chain link fatigue analysis. however, for fatigue analysis of mooring chain link, connection to the chain wheels at fairlead, chain link passing over bending shoes , or chain stopper linkers provided by chain hawse or chain stopper, the effect of the out-plane-bending (OPB) on the mooring fatigue should be considered. Since chain typically not coated or protected it is subjected to general corrosion. Splash zone are more potentially for corrosion of chain. To demonstrate the effects of these parameters on strength of mooring chain through a case study. To study the various phase during the life cycle of mooring from design to decommissioning and come up with a kind of a framework covering all important information. | |
