Describe：

The 84mm Grade R4 Mooring Chain is a critical load-bearing component in offshore and marine engineering, characterized by high strength, excellent toughness, and superior corrosion resistance, which are essential for adapting to harsh marine environments. certifications from major classification societies including CCS, ABS, and DNV-GL, ensuring its reliability in practical applications.

In terms of application scope, this mooring chain is mainly used in offshore continental shelf development projects. It is widely applied in offshore oil and gas development systems, including floating production storage and offloading units (FPSOs), semi-submersible drilling platforms, single-point mooring structures, and offshore buoys. Additionally, it is also used in large marine engineering vessels such as floating cranes and pipe-laying ships, providing stable mooring support for their offshore operations.
