BROOKS FORGINGS LIMITED

The mooring ring is made up of a 600x350x35mm thick base plate, 200mm inner diameter ring from 50mm diameter material, and u-bend also in 50mm diameter material. The rings were hot bent and flash butt welded in-house. Unlike standard welding procedures, flash butt welding uses no foreign material and allowed us to complete the necessary heat treatment to 8.8-grade specification.

The final assembly involved fillet welding the u-bend to the base plate which was pre-heated to alleviate cracking during the process.

A proof test to 80 Tonnes was required prior to the final supply. This was successfully completed by bolting together 2 sacrificial components back-to-back and pulling to the required load.

Once the necessary testing was completed the mooring rings were packed in specially made wooden packing cases and shipped to the customer.
