What ClampOn does

ClampOn AS is a Norwegian, privately held manufacturer founded in Bergen in 1994 that designs and produces non-intrusive ultrasonic sensors and monitoring systems for the international oil and gas industry, serving both topside and subsea applications. The company reports more than 25,000 sensors sold worldwide across 40+ countries and positions itself as the largest global supplier of passive ultrasonic systems for sand/particle detection. Its customer base comprises supermajors, national oil companies, independent operators, EPC contractors and subsea equipment suppliers that deploy ClampOn instruments for sand/particle monitoring, corrosion-erosion monitoring (CEM), pipeline PIG detection, vibration monitoring, subsea flow temperature measurement, leak detection and choke condition monitoring.

The product portfolio is built on a proprietary Digital Signal Processing (DSP) platform deployed for over 20 years across all sensor types and more than 4,000 subsea units. Core technologies include passive acoustic particle detection, Acoustic Guided Lamb Wave (AGLW) wall-thickness mapping via EMAT transducers (covered by a granted US patent and pending UK/Norway patents on the underlying lightweight tomographic algorithm), dual-mode acoustic-and-magnetic PIG detection, and a thermal-model-based subsea flow-temperature algorithm qualified to API17F and ISO 13628-6 (TRL 7, OTC 2022 Spotlight on New Technology). The portfolio also extends to a wireless BIRD product line (mesh-capable, battery-operated particle and multi-mode condition monitors) targeting downstream, unconventional and renewable energy markets.

ClampOn earns revenue from hardware sales of configured instruments (Ex i/Ex d e variants), a comprehensive field-services layer (installation, commissioning, sand-injection calibration, preventive/corrective maintenance, training, well testing, ad hoc support), and a smaller but growing recurring layer (ClampOn Cloud, Sand Management Program, Sand Client 4.0 software, CorrPRINT tomography). Pricing is handled on a project/quote basis rather than published tiers, reflecting the bespoke, integration-heavy nature of each installation. Distribution is exclusively direct, via Area Sales Managers and an in-house field service organization, with industry events (ONS, OTC, Eurocorr, AIMCS, OTD) serving as the primary demand-generation channel. The company is founder/management-owned with no disclosed external investors.

Revenue model

1. Hardware Sensor Sales: ClampOn generates primary revenue from the sale of non-intrusive ultrasonic monitoring instruments — topside and subsea particle/sand monitors, corrosion-erosion monitors (CEM), PIG detectors, vibration monitors, flow temperature monitors, and the BIRD wireless product line. Products are sold as standalone instruments or as part of configured monitoring systems. Both Ex i (Intrinsically Safe) and Ex d e (Flameproof) versions are available.
2. Professional Services & Field Operations: ClampOn offers a comprehensive suite of services including installation and commissioning of subsea and topside instruments, corrective and preventive maintenance, field calibration (sand injection), on-site training, software calibration, system health checks, system modifications and upgrades, well testing, on-site testing and certification, ad hoc support, and managed sand monitoring programs.
3. Software & Cloud Monitoring: ClampOn provides software solutions including Sand Client 4.0 (live sand rate data, diagnostic reports, intelligent trend analysis), CorrPRINT tomography software for CEM wall thickness mapping, and ClampOn Cloud for remote monitoring and data management. The Sand Management Program provides ongoing monitoring-as-a-service capabilities.
4. Sand Injection Calibration Services: ClampOn's service department performs sand injection calibration jobs to verify sensor accuracy and improve sand rate calculation precision. Jobs involve injecting known quantities of calibrated sand upstream of the particle monitor to establish a unique calibration step table for each sensor installation.
