The unplanned repair or replacement of subsea pipelines can be very expensive. Most pipeline failures are attributed to the problem of corrosion or erosion of the pipe walls. Periodic inspection of the pipelines will enable an operator to identify and pro-actively address these problems.
Subseaquest provides Pipelines Inline Gauge (Smart Pigs) and specialized tools from original equipment manufacturers for pipeline integrity surveys and management. These include Pulsed Eddy Current (PEC) measurement and Ultrasonic testing (UT) tools.
We also provide inspection of non-piggable subsea pipelines by deploying free swimming in-line inspection tools; Electromagnetic Acoustic Transducer (EMAT) and Magnetic Tomographic tools through.
These inspection tools are used to acquire data, which are analysed to determine the state and integrity of the pipelines. Miles of pipelines located subsea are inspected regarding metal loss, deposits, deformations and other integrity related issues without little or no interrupting to production.
