Optimizing Subsea Assets - From Reservoir to Deck

4Subsea is a leading provider of technology and services that help operators maintain production from subsea oil and gas fields and offshore wind farms. By combining expert engineering competence, practical experience and a digital service, we ensure the integrity of assets all the way from reservoir to deck.

  • Prevents Unplanned Riser Replacement of Production Shutdown

    Most oil companies operating flexible risers carry out annulus testing on an annual basis to ensure the integrity of the risers, and to detect anomalies early. Riser replacement or production shutdown due to riser failure entail significant costs, and frequent testing of flexibles reduces the chance of riser failure. With the patent pending Portable Annulus Tester PAT™ we have eliminated the need to send two technicians or engineers offshore by helicopter to perform the tests. 

    Significant Reduction of Risk and Cost

    PAT™ is an «Engineer-in-a-box» solution that removes the requirement for mobilising dedicated third-party personnel offshore. The solution typically reduces annulus test cost by 30% in the North Sea, while in remote regions simplified logistics reduces cost far beyond the 30% experienced in Northern Europenan waters.

    Automated and Digitized Riser Testing

    Testing is automated and results are digitised and available immediately during testing. The system presents results on the FlexTrack™ digital platform, accessible to both onshore and offshore personnel. The patent pending system is the first in the world to completely automate and digitize flexible riser annulus testing.

  • FlexTrack™
    Having well documented information at the right time can be the single most import issue in managing flexible line integrity. FlexTrack™ enables operators to have full control of their flexible line system in an easy-to-use digital platform....

  • Significant Reduction of Risk and Cost

    A considerable amount of the world’s total offshore production goes through flexible pipes. In 2017, 47% of all production on the Norwegian Continental Shelf were produced through flexible pipes representing 35% of total income. Losing control of flexible pipe performance may result in catastrophic environmental and financial consequence.

    Digitizing Riser Integrity  

    ​FlexTrack™ is a collaboration solution designed specifically to manage and process information regarding integrity management of flexible lines and umbilicals. FlexTrack™ may be integrated with other systems such as the operators document system or PI server, so that relevant information is displayed in context of the flexible line. The users get full control of all data relevant to the flexible line system while saving time spent on finding information.

    4Subsea’s portfolio of autonomous subsea sensors is developed to reduce ROV cost and improve integrity control of ageing assets....

  • Reducing ROV Cost with Autonomous Sensors

    4Subsea’s portfolio of autonomous sensors has been developed to monitor the integrity of subsea assets in order to displace ROV inspection cost. Our sensors monitor continuously for 5 years at a time and they will give you immediate feedback of any anomalies via satellite alarm. Neither maintenance nor personnel is required, as the autonomous sensor systems immediately transfer data through a satellite alarm if a failure is detected.

    Vast Array of Technoloy Applications

    Technology applications include monitoring of wellhead integrity, risers, mooring lines, subsea spools and manifolds, as well as monitoring of pipelines and subsea structures. The costs savings in using our expert personnel and advanced sensor technology for maintaining production are significant and long-lasting.

    Postpone ROV Inspections to 5 year Intervals

    Our engineers help you define a combination of sensors and alarm criteria allowing you to monitor integrity continuously instead of by intermittent ROV inspections. The sensors will also allow you to postpone ROV inspections to 5 year intervals. For regular subsea fields this will reduce ROV inspection cost in the range of 60%, while at the same time improve your control of the integrity of your equipment.
