Experimental Study on Wear Coefficient of Mooring Chain for Floating Offshore Structures

Floating wind turbine facilities installed in deep sea areas play an essential role carbon dioxide emissions reduction.One of the problems associated with commercialization these is maintenance cost for mooring chains.Therefore,it necessary to establish a quantitative wear evaluation method chains.Wear coefficient measured by tests one physical parameters evaluate performance metals.The pin-on-disk test generally performed obtaining coefficient.However, this had significant variation our past study.Additionally, it has difficulty use heat-treated surface chain under high pressure fully immersed wet condition.To reproduce actual situation,new machine was designed and were implemented validate accuracy.As result,it confirmed that proposed possible obtain significantly small compared conventional test.
