 Press Releases

  • Where is the engineer?

    OTC, Houston, May 1st 2017 - 4Subsea recently launched the Portable Annulus Tester (PAT™), a product that automates integrity testing of flexible risers. In fact, the less than 30kg rolling suitcase may replace the engineers going offshore for annulus testing.

    The groundbreaking technology digitises integrity management of flexible risers, at the same time making the operators a whole lot more cost effective.

    The objectives of the annulus tests are to verify the flexible riser outer sheath integrity and the functionality of the ventilation system. The hand carried test unit performs complete annulus tests, and algorithms are enabling the operator to take immediate action if anomalies are detected.

    PAT™ has successfully been used and proved on offshore operations for major operators in the North Sea and is available for worldwide operations.

    Interested in a demo of the solution?
    We have brought the “Engineer-in-a-box” suitcase to OTC – find us at stand #4432, Hall A.

    4Subsea is awarded a new contract for integrity management with Shell, using the digitalised web solution FlexTrack for integrity monitoring on Draugen, Knarr and Ormen Lange fields.

    Houston @ OTC, May 1st 2017 – The contract is a continuation and further development of a long-standing cooperation between Shell Norway and 4Subsea, enabling Shell to gain greater flexibility and insights in their data and integrity management. 4Subsea has provided engineering support and integrity management services for flexible risers, flowlines and umbilicals to Shell Norway since 2009.

    Time spent on integrity assessment from weeks to hours

    With the digitised services Shell achieves both better decision support for their subsea operations, reduced cost of integrity testing, and increased use of in-house personnel already on board the FPSO, hence avoiding mobilising personnel offshore.

    Being based on big data collection and advanced analysis, the solution reduces the time spent on integrity assessments from weeks to hours, since key information gets to be readily available when needed.

    Information control for better decision-making

    Integrity management of flexible lines and umbilicals involves several technical disciplines and sources of information. The data basis for the integrity status is often stored and managed out of context in different software systems, which makes the information scattered and inaccessible. As a result of this, status assessments may be based on batch processing and review of data with 6-12 months’ delay between evaluations.

    Live Data Management

    Having well documented data managed in a context based and live system can be the single most important issue in demonstrating integrity. That is why Shell integrates the FlexTrack solution in their integrity management program. The solution runs on the Microsoft Azure platform, utilising Azure’s scalability features to the full.

    “We are pleased that Shell Norway continues working with 4Subsea on digitising and automating their operations”, says Peter Jenkins, CEO of 4Subsea. “We see this as a signal of trust, demonstrating 4Subsea’s ability to deliver solid digital solutions that enable our customers to reduce both risk and operational costs.”
