Kenter Shackle Supplier for Anchor & Mooring Chain Systems

What is a Kenter Shackle (Kenter Joining Shackle)

The Kenter shackle is a detachable anchor chain connection shackle used to link anchor chains to mooring chains.

It appears like a common stud-link but is actually composed of two halves, a center chock, and a taper pin. As a leading Kenter shackles supplier, OLIPORTS ensures that every heavy-duty shackle meets strict maritime safety standards.

Kenter Shackle Structure Diagram

Two Halves (Body): Interlocking chain links that form the primary load-bearing structure;

Center Chock / Spigot: Aligns and locks the two halves together to prevent lateral movement;

Taper Pin: Secures the assembly via a self-locking tapered design; inserted from the narrow end;

Lead Seal: Prevents the taper pin from loosening due to vibration or impact

How to Open and Assemble a Kenter-Type Jointing Shackle

Many offshore operators ask how to remove a Kenter shackle during maintenance:

  • How to Open Kenter Shackle: Use a punch to drive out the lead plug, then hammer out the tapered pin.
  • Step 2: Remove the center spacer.
  • Step 3: Slide the two half-rings apart to attach the mooring chain.
  • Assembly: Follow the steps in reverse, ensuring the tapered pin is fully seated and sealing it with a new lead plug.

Applications of Kenter Shackle

Hip Anchor Chain Connection: oin standard 27.5m anchor chain shackles for merchant vessels, tankers, bulk carriers, and container ships. Kenter shackles are used on anchor chains to ensure a reliable connection and smooth passage through the windlass.

Offshore Mooring Systems: Connect mooring chains for FPSOs, semi-submersible platforms, TLP, and floating structures. Kenter shackles for offshore mooring provide high-strength, detachable connections for deep-water operations.

Engineering & Special Vessels: Heavy-duty connections for dredgers, crane vessels, offshore supply vessels, and naval ships. Kenter shackles are used in mooring systems to support anchor handling, positioning, and emergency release operations.

Maintenance & Replacement: Quickly replace damaged links without cutting the entire chain. The detachable shackle design saves time and costs during offshore maintenance.
