Flexible riser annulus testing and onsite gas analysis services

Fairtex Group provides flexible riser annulus testing and onsite annulus gas analysis solutions designed to support the integrity management of offshore flexible pipelines, risers, and subsea infrastructure. Our portable annulus test packs enable multiple integrity assessments to be performed from a single compact unit, improving offshore operational efficiency while reducing inspection time and logistics exposure.

Combined with advanced portable gas analyzers, Fairtex delivers real-time onsite analysis of annulus gas composition under actual operational pressure and temperature conditions. This approach enhances anomaly investigation, improves integrity diagnostics, and eliminates the delays and handling requirements associated with onshore laboratory testing.

Typical applications: offshore flexible risers, subsea pipelines, annulus gas monitoring, vent port testing, leak detection, flexible pipe integrity programs, outer sheath breach assessment, and offshore maintenance and repair campaigns.

What this service covers

Flexible riser annulus integrity testing

Fairtex provides annulus testing services including annulus vacuum testing, positive pressure testing, vent port flow testing, and annulus free volume determination. These assessments support evaluation of flexible riser integrity, annulus condition, and operational performance.

Onsite annulus gas analysis and monitoring

Using advanced portable gas analyzers, Fairtex performs real-time onsite gas composition analysis to support identification of degradation mechanisms, leak pathways, and integrity anomalies affecting flexible riser systems.

Inspection, repair, and maintenance support

Our offshore integrity services include flexible riser UT scanning, vent collar support, vent port clearing, leak detection, visual inspection, guide tube corrosion repair, and outer sheath breach repair designed to support operational continuity and long-term subsea asset integrity.
