What we do
Services built for drilling, production and mining
From a single lifting-gear certificate to a full QA/QC programme and the crew to run it.
Inspection & Certification
Independent inspection and certification of drill string, tubulars, BHA, lifting gear and rigs — by ASNT / PCN Level II and III inspectors, to the international standard that applies.
Pressure & Hydrostatic Testing
Hydrostatic, pneumatic and NDT testing that proves pipelines, vessels and components can safely hold pressure before they go into service.
Calibration
Laboratory and on-site calibration of measuring instruments — electrical, temperature, pressure, force, mass, volumetric, dimensional and analytical.
Dewatering
Complete pumpset rental for mine pits and project sites — supplied, installed, operated and maintained by our crews, with a 24-hour emergency call-out.
QA/QC & Third-Party Inspection
Quality assurance and third-party inspection of drilling and completion equipment, so nothing reaches the rig site without being checked against the right standard.
Consulting & Training
Modular technical training and consulting for inspection, lifting equipment certification, NDT, welding, HSE and quality management systems.
Human Resources
Contract staffing, permanent hire and managed workforce solutions for oil & gas, power & renewables, infrastructure, mining and chemical projects.
