How to order stud link anchor chain
To order stud link anchor chain you need five things: the chain grade (Grade 2 or Grade 3), the diameter, the number of 27.5 m shots, the accessories (Kenter shackles, end shackles, swivels, end links) and the class society that must certify it. All of these come from the vessel's equipment number and class rules. Add the vessel name, IMO number and delivery port and a supplier can quote.

- Forgetting the swivel or end shackle at the anchor end
- Not naming the class society, so the chain is tested without the right surveyor
- Mixing grades between shots on the same cable

Frequently asked questions
How do I find the right chain diameter?
The vessel's equipment number (EN) and the class rules give the required chain diameter and grade, and the total length. Use the class society's equipment table or the ship's original specification.
What certificates come with anchor chain?
Each shot is proof- and break-tested at a class-approved chain works under the surveyor's witness, and a class certificate is issued for the shots supplied.
How is chain marked and packed?
Shots are marked with the certificate number, and are usually shipped in bundles or on steel pallets, with accessories packed separately.
