We understand the links between data and degradation mechanisms. This domain expertise is leveraged in recommending most suitable inspection and monitoring techniques to gather relevant data, perform inspection results evaluations, and fitness for service assessments for continued service of the asset.
The process begins with development of risk-driven inspection plans. We project manage inspection campaigns to ensure relevant and quality data is gathered to help confirm the effectiveness of design barriers such as coatings and increase the knowledge of operational conditions.
To do this, we develop detailed inspection work scopes using knowledge of equipment design, applicable failure mechanisms, operational history, relevant inspection technologies and industry best practices. We then provide experienced inspection personnel with component-specific inspection checklists and datasheets to gather equipment condition data. Once the inspection has been completed, we provide a full engineering assessment of the results which outlines observations made, potential risks, and most importantly, recommendations and next steps.
Our experience includes supporting general visual inspections, cathodic protection surveys, non-destructive testing methods, above-water UT, UWILDs, LiDAR, post-hurricane, and life extension inspections. Our services include:
Inspection and logistics planning
Workscopes / procedures development
Offshore inspections execution and project management
Inspection data storage and management
Inspection data review and engineering evaluations
Inspection tool selection and qualification support
Clarus offers comprehensive corrosion assessment services that evaluate data from various sources to determine the fitness of a system. A standard internal condition assessment is done periodically during operations, but a more comprehensive assessment is critical for life extension.
What Our Corrosion Assessment Covers
Short term and long term corrosion probe and coupon monitoring data combined with records of chemical injection availability allow our corrosion specialists to assess the internal health of the system. Internal corrosion data collected serve to demonstrate the effectiveness of the current corrosion management strategy, but are also crucial inputs for corrosion wall loss analysis performed as part of fitness for service and life extension assessments using industry available corrosion modeling software.
We help perform pigging feasibility studies, ILI tool selections and qualification, vendor management, project managing ILI campaigns, and performing fitness for service assessments for code compliance. In-Line-Inspection (ILI) results are assessed for features including metal loss (corrosion or wear), manufacturing defects, and deformation. Identified active metal loss features during ILIs are evaluated for Fitness for Service assessment. Routine maintenance or cleaning pigging helps maintain the production flow path from deposits and debris. Debris retrieved during cleaning pigging can be analysed for composition to further understand production fluid chemistry.
While Engineering Critical Assessment (ECA) is performed during the design phase to determine acceptable flaw size in the pipeline, Fitness for Service (FFS) assessment is performed during operations to evaluate existing defects or flaws and determine the pipeline remaining life. Internal corrosion assessment and ILI results are important inputs for the FFS assessment.
