Chain Support Buoys
Hongruntong Marine’s chain support buoy is designed to support subsea mooring chains and reduce tension in SPM systems. It provides reliable buoyancy and protects chains from seabed abrasion.
Hongruntong Marine’s Chain Support Buoy is engineered to provide superior buoyancy and protection for mooring and anchor chains in harsh marine environments. Featuring an advanced dual-layer construction – a rugged polyurethane (PU) outer shell encapsulating high-performance closed-cell foam – this buoy delivers unmatched durability, corrosion resistance, and long-term buoyancy stability. Ideal for offshore rigs, floating docks, ship mooring systems, and aquaculture installations.
Characteristics
► Durable material
► Polyurethane elastomer
► Strengthen skin tear resistance
► Even if the skin is severely damaged, it hardly sinks
► High impact energy absorption
► Can be customized according to requirements
Applications
-
Offshore oil & gas mooring systems
-
Port and harbor anchor chains
