Earlier this year in July 2021, Geo Oceans and Sonomatic were engaged by Jadestone Energy Australia to provide wall thickness scanning capabilities for use in the Montara Subsea Field. The aim of the project was to deploy tooling that would corrosion map the field joints at eight predetermined locations along the production flowline. By utilising small ROV systems to deploy the pipeline scanning tool, the system was able to be deployed from a vessel of opportunity.
The team designed and developed an entire inspection suite that would address a range of challenges often experienced with wall thickness mapping on non-piggable subsea pipelines, whilst also significantly reducing cost by utilising a small ROV deployed from an already in-use and positioned vessel. The capability brought together a full vessel deployed ROV inspection suite with small ROV integrated tooling for circumferentially cleaning and scanning subsea flowlines using a range of advanced NDT techniques.
The synergy of these systems and teams enabled the successful completion of not only the project but parallel development of unique, complex technical systems that can be used for a range of applications in the future, whilst significantly reducing the cost of scanning subsea pipeline.
