John Shaw Semi-Submersible Drilling Rig

We were awarded the task of rebuilding eight Skagit anchor winches onboard the John Shaw drilling rig.

All parts and components of the winches needed to be cleaned, blasted and painted.

Brake bank linings were removed, inspected, shot blasted and relined.

New bull gears and drive pinions were manufactured and installed, and the gypsy wheels required complete replacement.

All hydraulic cylinders and the main reduction gearboxes were overhauled and reinstalled.
