Offshore Mooring Chain

Offshore Mooring Chain

Offshore mooring chains, different from common anchor chains, are widely used in oil drilling platforms and other offshore structures to fix the platfroms and avoid movement. Due to the work environment is very bad, the mooring chains should have high strength, good toughness, wear resistance, fatigue resistance, corrosion resistance etc..
