Upstream, midstream and downstream operations supported with preventive maintenance, calibration and rapid emergency response — because unplanned downtime on a process line is never cheap.
Advanced Systems and Technologies LLC supplies, calibrates, tests and maintains the instruments and equipment that keep Middle East industry running — from first commissioning to lifetime support.
Trusted across the GCC in
Advanced Systems and Technologies LLC (AST) is a Middle East-based technical solutions provider supplying industrial equipment, precision instrumentation, calibration and non-destructive testing services, and full lifecycle field support across five core industries.
We built AST around a simple idea: clients shouldn't need to coordinate a dozen vendors just to keep operations running. One accountable partner. One point of contact. One consistent standard of quality — from the first quotation to the last service report.
Equipment sourcing, calibration, testing and maintenance under one contract and one team.
Calibration, NDT and inspection performed to recognised international methods and standards.
Engineers and service vehicles positioned to respond on-site or in-lab across the GCC.
Preventive maintenance and rapid response designed to protect schedules, not just fix breakdowns.
No matter which service you start with, every engagement follows the same disciplined process — so you always know what happens next.
We review your equipment, industry requirements and timeline, then scope the right mix of products and services.
One proposal covering equipment, calibration and field work — coordinated internally so you sign a single agreement.
Engineers mobilise, equipment is sourced or tested, and work is carried out to method and to schedule.
Certificates and reports are issued, and we stay on as your ongoing maintenance and emergency-response partner.
Seven integrated service lines—inspection, consultation, repair, maintenance, training, installation, and emergency response—backed by an extensive equipment and product supply network. Every stage of your equipment's life is covered by one team.
On-site calibration, non-destructive testing and remote visual inspection performed to recognised standards.
We discuss findings with you on-site, explaining what the data shows and recommending maintenance or repair strategies.
Hands-on equipment repair and component replacement on-site, paired with scheduled preventive maintenance to keep equipment operating reliably and extend asset life.
We brief your team on findings, explain maintenance strategies, and provide documentation so your operations staff understands equipment condition.
Professional on-site installation and startup of new equipment, ensuring correct setup, testing, and handover documentation from day one.
Direct supply of new industrial equipment and instrumentation from established manufacturers, matched to your process requirements and backed by local calibration and service support.
Rapid response to urgent equipment failures, breakdowns, or critical issues. We dispatch experienced technicians to diagnose and repair quickly.
Same technical discipline, different equipment and compliance needs. We adapt our service model to how each industry actually operates.
Upstream, midstream and downstream operations supported with preventive maintenance, calibration and rapid emergency response — because unplanned downtime on a process line is never cheap.
Production lines depend on precise instrumentation and rapid parts sourcing to hold takt time and quality tolerances — we keep both moving, from the sensor floor to the spares shelf.
Vessels and offshore platforms supported through rapid equipment sourcing and close coordination with port facilities — so a delayed part never means a delayed departure.
Thermal and renewable assets kept calibrated and compliant through scheduled testing, inspection and maintenance — supporting the reliability targets utilities are measured against.
MRO and ground facility support with precision calibration and inspection delivered to aviation-grade standards, documented and traceable for every audit.
Headquartered in the United Arab Emirates, our engineers and service vehicles are positioned to respond quickly across the GCC — on-site at your facility or in-lab at one of our calibration centres.
Wherever your operation sits in the region, AST coordinates equipment, testing and technical support without the delay of switching vendors between countries.
Committed To Recognised Practice
Yes. Alongside scheduled maintenance contracts, our emergency response line is available during business hours, with engineers positioned to reach client sites across the GCC without waiting on a new vendor onboarding process.
Yes. Many of our clients operate facilities in more than one country. We coordinate equipment, calibration and field visits under a single regional agreement rather than separate local contracts per site.
Our calibration and testing work follows internationally recognised methodologies aligned with
Both. We source genuine OEM parts through our vendor network, and where lead time or budget calls for it, we can advise on qualified compatible alternatives — always flagged clearly in the quotation.
Our target for emergency call-outs is under 24 hours within our core coverage areas. Scheduled maintenance and installation visits are planned against your production calendar, typically confirmed within 2–3 business days of scope agreement.
