When your drilling or workover program demands precision tubular preparation, NAPESCO Australia delivers OCTG machining, make-up, break-out, and thread repair to API Q1-aligned standards — locally in Darwin, reducing logistics risk and keeping your rig on schedule.
Supporting offshore platforms, onshore wells, and intervention operations across the Browse Basin, Timor Sea, and Northern Australia.
From precision CNC thread repair to tubular bucking, hardbanding, and API inspection — every OCTG service your drilling program needs, delivered locally in Darwin.
Precision CNC thread repair on OCTG tubulars using a Mazak PowerMaster-N Chucker with MAZATROL 640T control. Suitable for OCTG tubular threading and repair for API and premium connections.
Controlled make-up and break-out of OCTG connections using a fully rotational 70,000 ft-lb hydraulic bucking unit with no-mark jaws for premium connections including VAM, Tenaris, JFE, and Grant Prideco.
Application and reapplication of wear-resistant alloy weld overlay to drill pipe tool joints, reducing casing wear by up to 50% and extending drill string life up to 3×.
Comprehensive API thread gauging using calibrated ring and pin gauges across a wide range of pipe sizes. Dedicated gauge room with Mitutoyo precision instruments and Gagemaker gauge sets.
Inspection services supporting the integrity of OCTG and drilling tools prior to deployment. Specialist inspection support ensuring tubulars and assemblies meet operational requirements before going downhole.
Comprehensive mobilisation preparation and support for offshore and onshore drilling programs. Rig-ready OCTG preparation ensuring tubulars are inspected, made-up, and certified prior to deployment.
Every piece of equipment in our Darwin facility is selected specifically for OCTG work — sized for the pipe, built for the environment, and maintained to API standards.
Heavy-duty CNC lathe with MAZATROL 640T conversational control. Large-bore capacity specifically suited to OCTG pipe diameters, delivering precision thread profiles for API and premium connections.
Hydraulic make-up and break-out unit with dual spindle heads, full 360° rotation, and computerised torque monitoring with automatic PDF report generation.
Automated hardbanding system with induction preheat, TWYX fume extraction, and precision weld overlay capability for tool joint protection and end-face grinding.
Full set of API ring and pin gauges covering all major OCTG thread forms. Supplemented by Mitutoyo precision instruments and Gagemaker gauge sets in a dedicated, climate-controlled gauge room.

Darwin is the only logical home for a Northern Australian OCTG facility. The nearest comparable facility is over 1,800 km away. Every kilometre of unnecessary pipe movement adds cost, time, and emissions risk to your program.
NAPESCO Australia employs a dedicated local workforce. We do not operate a fly-in, fly-out (FIFO) crew. This means lower mobilisation overhead, better continuity of skilled personnel, and direct support for the Northern Territory economy — a key commitment increasingly mandated by major operators and government stakeholders.

NAPESCO Australia provides precision OCTG machining, bucking, and repair services from Darwin, Northern Territory. The facility is established to support drilling, workover, and intervention operations by reducing logistics exposure, turnaround time, and tubular integrity risk associated with long-distance pipe movements.
NAPESCO Australia forms part of the wider NAPESCO group of companies, which has delivered oilfield machining, repair, and technical support services across the Middle East and North Africa since the late 1990s. This legacy has shaped the technical standards, execution discipline, and operational philosophy applied within NAPESCO Australia today.
NAPESCO Australia operates as a distinct, locally governed entity, with full responsibility for its Australian operations, compliance, and contractual performance.
The NAPESCO group has operated across multiple oil-producing jurisdictions, with the Darwin facility the group's Australian presence.
