What Are the Advantages of a Field-Proven Subsea CT Scanner
The upkeep of subsea pipelines, which involves ensuring safe offshore operations as well as conforming to precise legal regulations, is vital for gas and oil operators. In this respect, it is essential to use accurate and reliable equipment when managing waterflood processes. These must be able to easily detect pipeline integrity problems as well as evaluate wall thickness with extreme precision. All of this must be achieved with minimum damage to the pipelines in process.
The issue with ‘hotspot’ checks
Problems in subsea pipeline preservation can occur because procedures such as in-line inspection often lack flexibility. In this instance, operators may fall back on ‘hotspot’ inspections in localised areas. From this, more inspections can be carried out — but it isn’t efficient nor cost-effective to do this.
When a field-proven subsea CT scanner is in place, it reduces the time wasted on such hotspot checks. Instead, the software can find defects and inform the operator whether or not these issues are impacting the pipeline enough to push it out of its specified tolerance. With these issues accounted for, operators can then undertake a more detailed scan of that area, rather than extending the scanning scope blindly after hotspot inspections.
The implementation of technology for all coating type
The benefit of using a field-proven subsea CT scanner, applying a non-intrusive scanning approach is the ability to work with all kinds of covering or coating the pipeline may have. One such subsea pipeline inspection scanner, Discovery, can scan for wall thickness in a number of different pipeline systems, from risers, piggyback lines, and pipe-in-pipe. The below shows how Discovery software does this in one, real-time scan:
Lloyd’s Register recognition advantages
Additional advantage of using field-proven subsea CT scanners such as Discovery, with third-party recognition from maritime classification society Lloyd’s, is that it holds an extensive experience and is strongly reliable. For example, with over 2,000 scans and numerous accurate readings and findings in its repertoire, this scanner can surely help operators in the industry the world over. Not only does implementing such a scanner help save time, it also helps financially — operators could see savings of up to 1/3 on inspection campaigns by using a more accurate method than traditional scanning or hotspot inspections.
