One of TWI’s current projects is a contract with the Pipeline Research Council International (PRCI) for the development and verification of an ultrasonic inspection tool for pipelines, using Alloy 625 weld overlay cladding deposited by the tungsten inert gas process. Phase 1 of this project began with a review of potential techniques, including ultrasonic and electromagnetic methods. Phase 2 saw the development of a phased array ultrasonic testing (PAUT) tool for detecting a range of potential flaws that may arise during fabrication and while in fatigue critical service as part of riser systems.
The PAUT tool used commercially available components (such as probes and instrumentation) along with a specific arrangement to
Phase 3 – the final phase of the
A recent project of TWI’s, undertaken in collaboration with European partners, involved the development of a remotely operated vehicle (ROV) deploying a guided ultrasonic wave (GUW) transducer collar for testing subsea pipelines for corrosion. The GUW method enables ultrasonic testing at long range, with the capacity for detection on either side of the test location at distances of several tens of
Other developments include a simple to use
Looking to the year ahead
Tat-Hean Gan, Business Group Manager, Integrity Management, at TWI, said: “The current market scenario has resulted in reduced spending by oil and gas companies on research, with one of the main outcomes being that companies are now investing in prolonging the lifespan of their existing equipment and assets. The main area of focus will be advanced methods for life extension, using structural monitoring and predictive analysis based on historic data. This will include the creation of tools and sensors to monitor, inspect and assess damage as it develops and the results of such analyses."
