Offshore Mooring Chain is used as an important safety anchoring facility on ocean development facilities such as offshore drilling, oil production and mining etc. They are mainly used for offshore oil platform, offshore oil storage ship, offshore buoys and other other ocean development activities. There are generally 5 grades of steel for offshore mooring chain: R3, R3S, R4, R4S, R5. R3 and R3S grade mooring chains are most often used for the marine continental shelf development facilities. While, the R4 grade mooring chains are used for deep-sea development facilities. TUF mooring chains are approved by RINA, CCS, ABS, NK, LR, DNV, GL, BV, KR, RS, IRS and etc. Stud and studless link chain diameter: 34mm to 162mm How to order anchor chain ? â??
