.... INTRODUCTION Mooring chain is a standard component in mooring systems for offshore platforms. Although considered a very robust component, corrosion and wear can over time reduce the strength and fatigue capacity. Observed wear are such as between and on links at the exit of chain stoppers and fairleads...

For the design of the mooring system, additional consideration needs to be given to the limitation of the relative rotation amplitude to prevent collision of the modules. The impact of the mooring system on the connector load should...

The scale of wind farms will be larger and larger in the future (IRENA, 2019), therefore, the weather and sea conditions in a large wind farm will not be able to be treated as uniform. The damage risk on floaters and mooring systems will be different under the nonuniform weather and sea condition...
