The Permanent Wire Chaser is a ring-shaped tool designed to provide a chasing system for semi-submersible drilling rigs equipped with wire rope mooring cables for drilling in deeper water. It is used worldwide with single and twin shank anchors on wire-only and wire/chain combination moorings.
The chaser features a Rocker made from an abrasion-resistant alloy with higher through-hardness. The Rocker is mounted on a through bolt, which prevents the nut from seizing and provides a detachable feature for easy assembly to the mooring cable and Rocker replacement when necessary. The material of the chaser is not harder than the material of the wire and chain, ensuring no damage to the mooring components during recovery.
