Quick and Efficient Annulus Volume Testing, with Real-time Results.

 

Our Annulus Volume Testing service (delivered in partership with 4Subsea), allows for speedy and cost-effective annulus testing of risers. The objectives of the tests are to verify the integrity of the flexible riser’s outer sheath, and to also verify the integrity of the ventilation system.

This service is deployed using 4Subsea’s Portable Annulus Tester (PAT), a portable ‘engineer-in-a-box’ solution which performs fully automated annulus tests and is designed to allow for quick deployment.

The PAT performs tests in a consistent manner and requires less personnel, thereby saving costs and improving overall operational efficiency.

Other advantages include;

  • Detection of outer sheath breaches
  • Detection of blocked vent ports
  • Detection of liquid filling in annulus
  • Live results during operations
