Principle of Operation & Functions

Functions of Chain for Marine Fender

Keep the fender in position: The chain ensures that the marine fender stays fixed in place, even under heavy waves or strong winds.
Absorb impact force: The chain helps reduce tension and impact forces when a vessel contacts the fender, protecting it from damage.
Ensure safety: Prevents the fender from drifting away or detaching during berthing operations or in harsh weather conditions.

Installation Procedure of Fender Chain

Inspect chain and shackles:
Ensure no chain links are worn, broken, or heavily corroded.
Shackles must be properly tightened without cracks.
Connect chain to marine fender:
Use shackles to connect one end of the chain to the lifting eye of the fender.
Make sure the shackle is tightened correctly and securely.
Connect chain to quay or mooring buoy:
The other end of the chain is attached to the quay or buoy via shackles or anchoring devices.
Chain tensioners can be used to adjust length and tension properly.
Check tension and test:
After installation, check chain tension to ensure the fender is in the correct position.
Test by pulling or lightly pushing the fender to verify stability.
