Offshore Mooring Chain Introduction
Offshore mooring chain is mainly used for offshore oil floating production system, semi-submersible drilling platform, single point mooring structure, FPSO mooring facilities structure and so on.
Given that the mooring chains have to be long-term immersed in the seawater, the mooring chains have the features of high strength, good toughness, seawater corrosion resistance, fatigue resistance, wear resistance and other properties.
Stud Link Anchor Chain
The offshore mooring chain is available in Grades R3, R3S, R4 and 5, Sizes Range from Ø11-167mm.
The Offshore Mooring chain can be supplied with certification from any of the major classification societies.
