Effective maintenance of your drawworks means inspection and service of the primary load path. This includes the main drumshaft, service brakes (band or disc type), emergency brakes, spline couplings (where applicable) the drawworks frame and its foundations, connecting it with the rig floor.
We carry out on site Category III 6-monthly inspections, observing your equipment during operation for indications of inadequate performance. We inspect for corrosion, deformation, loose or missing components, deterioration, improper lubrication and visible external cracks. We’ll partially disassemble and further inspect including non-destructive testing of critical areas and components to identify wear that exceeds the manufacturer’s allowable tolerances.
We support our customers with complete Category IV 5 yearly recertification of their drawworks which includes further inspection and complete disassembly, 100% non-destructive testing of all primary load-carrying components as defined by the manufacturer. Repairs are made as necessary to bring all components back within manufacturer tolerances. The equipment is then reassembled, reinstalled and commissioned.
Our ongoing condition assessment and monitoring accommodates clients Category I daily inspection and Category II weekly inspection needs.
