The project required the inspection of numerous, mostly trenched, pipelines in water depths of 12m or less at their shore approach to the onshore terminal.
NCS used their Autonomous Underwater Vehicles (AUV) to inspect the pipelines, primarily using multi-beam echo sounder (MBES) and side scan sonar (SSS). Where visibility allowed the 4-frames/second HD colour camera was also used to bring a further dimension to the data and imagery produced. All of this activity was operated from a small near-shore vessel with a 3 man survey team onboard.
The project was able to deliver the following results for the client:
NCS Survey own and operate a fleet of three low logistics AUVs which are air transportable. Performing their first scope of work in 2009 they are now a proven leader in low logistics AUV operations in the upstream oil and gas market.
