Chafe Chain

Hongruntong Marine manufactures OCIMF chafe chains, SPM chafe chains, chafe chain type B, and 76mm chafe chains for offshore mooring systems. Built for durability, safety, and compliance with OCIMF and SPM standards.

Hongruntong’s chafe chains are engineered to provide maximum abrasion protection and load-bearing strength for critical mooring systems. Designed specifically for harsh offshore environments, our chafe chains are forged from high-grade R3 and R4 mooring steel, ensuring long-lasting performance under extreme mechanical stress. 

Hongruntong Marine provides high-performance OCIMF chafe chains, SPM chafe chains, and chafe chain type B products specifically engineered for offshore loading and Single Point Mooring (SPM) systems. Our chafe chain 76mm models are designed and tested according to OCIMF standards, ensuring optimal performance under extreme marine conditions. These chains serve as a critical connection between the tanker and buoy, protecting the mooring hawser from abrasion and excessive load.
