4Subsea’s annulus monitoring solution AMOS™ provides safe and cost-effective operation of flexible risers. The system monitors the riser annulus diffusion rate, detecting early signs of riser failure, reducing risk and averting potential costly replacement of risers. AMOS™ enables safe operations and improved decision-making, averting costly unplanned replacement of risers.
4Subsea’s AMOS™ is a continuous annulus monitoring system for new and existing (retrofit) flexible risers. It uses a patent pending method to detect failures such as outer sheath damages and blocked ventilation ports early on, hence preventing costly replacements, shutdowns and accidents. AMOS™ also provides the option of automated annulus free volume testing as well as automated nitrogen annulus testing.
