Oil & Gas Drilling Rigs

Rigs are supplied to API specification references 4F, 7K, 8C, 6A and 16C, with configurations selected for the project.

• CAT or Cummins engine options.
• K-type mast with swing-up or piled-box substructure options.
• Electric-drive drawworks with disc braking.
• Automatic electronic controls and DC or AC variable-frequency speed regulation.
• Drilling-fluid circulation and well control systems.
• Top drive selected to the customer’s required brand and specification.

Modular rigs are configured for locations including offshore sites, deserts, plateaus and polar regions. The mast, drawworks, substructure and associated equipment are selected to suit the operating environment.

• Drilling depth range: 1,500–9,000 m.
• Electric, compound or mechanical drive.
• K-type mast and box-type or swing-up substructure.
• Top drive available.

Trailerized modules and pin connections reduce the number of rig-up and rig-down operations. This range covers 1,000–2,000 hp rigs for projects requiring frequent moves.

• AC variable-frequency drive.
• Hydraulically raised K-type mast with two-stage telescoping.
• Pin-connected modules designed for assembly without a crane.
• Automatic driller with hydraulic disc brakes.
• Digital controls with independently driven drawworks and rotary table.

Helicopter rigs are designed for remote sites that are difficult to reach by truck, including tropical rainforest locations. Modular construction supports transport, assembly and dismantling.

• Drilling depth range: 2,000–5,000 m.
• AC variable-frequency drive.
• K-type telescoping or swing-up mast.
• Module weight options: 2.72, 4 or 10 metric tonnes, according to transport requirements.
• Pin-connected modules and instruments selected for hot, humid or low-temperature conditions.

Materials, welding, machining and heat-treatment processes are selected for cold operating environments. Configurations include pad, modular and truck-mounted rigs.

• Operating temperature: −45 to +45°C; minimum storage temperature: −60°C.
• Cold-resistant components and engine-start assistance.
• Wind walls, insulated enclosures, electric heaters, air heating and air conditioning for operating areas.
• Heat tracing and heaters for circulating pipelines, hydraulic, air and electrical systems.

Truck-mounted rigs are available in 450, 550, 650, 750 and 1,000 hp configurations for shallow and intermediate-depth wells. Designs can be adapted for cold climates, deserts and mountainous terrain.

• Centralized electrical, pneumatic and hydraulic controls.
• API 4F mast.
• Main drum with integral Lebus grooves, a band or hydraulic disc main brake and an auxiliary brake.
• Heavy-duty axles, high-strength frame, hydraulic power steering and dual-pipe braking.
• Optional top drive and emergency motor.

The power system, drawworks, mast, travelling block and drive system are installed on a semi-trailer to support site-to-site moves.

• Available depth series: 1,500, 2,000, 3,000 and 4,000 m.
• Auxiliary double-wing mast supports for high lifting loads on the 4,000 m rig.
• Three parallel rails for single-row cluster-well drilling.
• Operating temperature: −45 to +45°C; minimum storage temperature: −60°C.

Time Rolling normally provides a one-year warranty from installation. The stated support programme includes site visits approximately every 12 months during the first two to three years, with technical assistance during those visits.

Engineers can provide 60–90 days of on-site installation and operational training for initial commissioning. Confirm the support scope and schedule with the project quotation.
