Annulus vent port inspection and unblocking services

Fairtex Group provides annulus vent port inspection and unblocking services for offshore flexible risers and venting systems used within the oil and gas industry. The service is designed to restore venting functionality, support annulus integrity management, and reduce operational risks associated with blocked vent tubing and restricted vent flow conditions.

Using specialized fiberscope inspection systems and dedicated cleaning tools, Fairtex performs internal inspection of vent tubing, identifies obstructions, removes debris, and restores operational vent pathways within flexible riser venting systems. The process supports safe and efficient offshore maintenance activities while minimizing operational disruption.

Typical applications: offshore flexible risers, annulus vent systems, vent tubing obstruction removal, flexible pipe vent maintenance, subsea integrity programs, offshore inspection campaigns, and vent flow restoration activities.

What this service covers

Fiberscope inspection and obstruction identification

Fairtex utilizes fiberscope inspection equipment to inspect annulus vent tubing and identify internal blockages, debris accumulation, excess tube protrusion, and operational restrictions affecting vent system performance.

Vent port cleaning and blockage removal

Where obstructions are identified, specialized cleaning cables are deployed through the vent tubing system to break up and remove blockages. The cleaning process includes debris extraction using vacuum systems to restore unrestricted vent flow.

Post-cleaning verification and integrity support

Following cleaning activities, Fairtex performs re-inspection of the vent tubing using camera systems to verify complete blockage removal and confirm restoration of vent system functionality and annulus integrity performance.

Key Takeaways

  • Provides fiberscope inspection and blockage identification for annulus vent systems.
  • Supports vent port cleaning and obstruction removal for flexible risers.
