DURABILITY OF SEAWATER RESISTANCE STAINLESS STEEL LINING APPLIED FOR “INCLINED LEVEE BODY TYPE BREAKWATER”

A new corrosion prevention method for offshore steel structure using seawater resistance stainless steel sheets has been developed. The seawater resistance stainless steel sheets are welded to the structures by the indirect seam welding method. This stainless steel lining was applied to the splash and the tidal zones of the inclined levee body type breakwater. Since the breakwater faces an open sea, the splash and the tidal zones are subjects to corrosion by wind brown salt, damage due to occasional impacts with floating debris and fluctuating stress by wind and wave.The experimental results indicate good corrosion resistance in seawater, good impact resistance and good mechanical properties, therefore this stainless steel lining will give successful and economical corrosion protection of steel structures.
