4Subsea products

Automated and cost effective riser annulus testing. The Portable Annulus Tester PAT™ is an “Engineer-in-a-box” solution that removes the requirement for mobilising dedicated third-party personnel offshore. The patent pending system is the first in the world to completely automate and digitise flexible riser annulus testing. The hand-carried unit allows for simple and cost-effective annulus testing of risers using your own personnel.

Reduce your flexible riser costs. 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. The results are safe operations, improved decision making as well as reduced cost.

Using a Digital Twin for improved decision support and reduced cost. SWIM™ (Subsea Wellhead Integrity Monitoring) measures critical parameters on the wellhead during drilling operations, providing KPIs and prediction analysis as a digital service. By combining expert engineering and operational experience with artificial intelligence, machine learning and data analytics, we can offer an industry-leading digital service, including advanced autonomous, retrofit sensor technology. 4Subsea was awarded the 2018 Product Leadership Award from analyst company Frost & Sullivan for SWIM™.
