Tracerco details latest subsea inspection programs

Tracerco has secured contracts for seven subsea inspection projects.

BILLINGHAM, UKTracerco has secured contracts for seven subsea inspection projects.

These involve providing flow assurance and asset integrity data for pipelines, flowlines, and risers in the North Sea, Gulf of Mexico and offshore West Africa.

The company will use its Discovery subsea CT scanner to provide each operator with tomographic images of pipe wall thickness and contents to enhance understanding of the pipeline condition and the process fluid.

This is a non-intrusive inspection method, Tracerco stressed, so all the offshore assets will remain operational throughout each project, limiting the potential for deferment of production.

The first of the two North Sea assignments will focus on integrity assessment following potential damage to an export pipeline, where the coating had suffered noticeable damage.

In this case, Discovery will be used to determine whether the damage extended to the pipeline itself. The second project will be a repeat inspection of another export pipeline to assess whether there has been any further degradation to the pipe wall thickness since an initial inspection in 2015, with the data assisting an ongoing pipeline life time assessment program.

In the GoM, the company will use Discovery to inspect the flowline and riser of a gas line for potential integrity issues, to investigate potential condensate hold-up, and to obtain baseline integrity data on a new pipeline system.

The system will then be deployed annually to re-inspect the new pipeline system for potential corrosion / corrosion growth rates.

The other three projects will all be off West Africa, with Discovery used to inspect various flowlines to determine whether they can be extended past their original design life.
