Integrity support
In addition to provision of the subsea inspection service, Sonomatic assists clients
with ensuring the inspection provides the best possible information on which to
base integrity decisions. This includes assistance with the following:
)
Defining the inspection performance requirements so the integrity objectives
are met.
)
Demonstration and qualification of inspection performance, including detailed
technical justifications for critical applications.
)
Determination of the coverage requirements and locations for limited coverage
inspections where the aim is to ensure the inspection provides sufficient
information to assure integrity.
)
Statistical simulation studies to assess the performance of candidate inspection
strategies (techniques, coverage and locations) so that the optimal approach
can be adopted.
)
Analysis of inspection performance achieved in the field. This is based on
detailed analysis of the raw data to establish performance metrics.
)
Statistical analysis of data to validate absence of degradation.
)
Statistical analysis for low coverage inspections to estimate the worst case
conditions in areas not inspected.
)
Analysis of ILI verification data and statistical analysis of ILI data sets to
provide more accurate feature depths, corrosion growth and remaining life
estimates.
)
Fitness for purpose assessments using standard code based methods,
probabilistic approaches and nonlinear finite element modelling based on the
inspection data.
Research and development
As the amount of subsea infrastructure grows and existing infrastructure ages,
there is a growing need for subsea inspection. Sonomatic is investing heavily in
research and development in this area and is bringing to market a number of new
techniques for subsea deployment. These include shear horizontal electromagnetic
acoustic transducers (SH-EMATs) and dynamic response spectroscopy (DRS).
The technique based on SH-EMATs has been developed for rapid screening of
subsea pipelines and structures for degradation in the form of wall loss. This will
allow more rapid inspection in situations where the aim is to cover large areas.
DRS is an ultrasonic technique that uses lower frequencies and is able to provide
quantitative inspection of steel wall thickness through thick and/or attenuative
coatings. These new techniques enable Sonomatic to more widely address the
market needs for inspection and are opening up new applications.
