Chains

Chains are used for two reasons – to suspend/support the fender or to control the deflection geometry during horizontal or vertical shear. Open Link (Studless Link) and Stud Link chains are available in various strength grades. Open link chains can also be supplied with different link lengths from 3D to 5D to suit each specific design. Shackles and other accessories are all referenced to the nominal chain diameter for equivalent strength and typically of larger diameter material. However, it is common to use shackles the same size as the SL2 grade open link chain to provide an easily replaceable “weak link” in the system.

Link Chain

Chain properties are based on Bureau Veritas rules (Table 10-II for stud link and table 10-III fpr open link), which are generally similar to Lloyds and ASB standards. However, chains can also be supplied to many other international standards such as DIN, BS and JIS if preferred. Chains are an important component of a fender system and require careful design. Please ask us for further advice on selecting and specifying chains.
