Pipeline Integrity & Rehabilitation

DIRECT ASSESSMENT
Direct Assessment provides a structured approach to evaluating the integrity of pipelines where specific threats to the asset need to be identified and managed. NNDT undertakes assessment activities to identify areas requiring further investigation, enabling clients to make informed decisions regarding inspection, maintenance and rehabilitation.
ECDA — EXTERNAL CORROSION DIRECT ASSESSMENT
External Corrosion Direct Assessment (ECDA) is a systematic process used to assess the likelihood and severity of external corrosion on buried pipelines. By combining indirect inspection techniques, direct examination and evaluation of findings, NNDT assists clients in identifying corrosion threats and prioritising areas requiring intervention, helping to reduce the risk of unexpected pipeline failure.
ENGINEERING SERVICES
NNDT provides engineering support associated with pipeline integrity, cathodic protection and rehabilitation activities. Our engineering services assist clients in evaluating inspection findings, developing appropriate remedial strategies and implementing practical solutions aligned with the operating requirements and integrity objectives of their assets.
FITNESS FOR SERVICE
Fitness-for-Service (FFS) assessments assist clients in determining whether components containing identified defects or degradation can continue to operate safely under defined service conditions. NNDT can support the evaluation of identified anomalies and provide technical input to assist clients in making informed decisions regarding continued operation, repair, replacement or monitoring.
COMPOSITE REPAIRS
Composite repair systems provide an efficient solution for restoring the structural integrity of pipelines and other components affected by corrosion, wall loss or localised damage. NNDT provides composite repair solutions designed to reinforce affected areas and extend asset service life while, where suitable, reducing the need for extensive excavation, replacement or prolonged shutdowns.
RECOATING & COATING REPAIRS
The coating system is one of the primary barriers protecting buried and exposed pipelines against corrosion. NNDT provides recoating and coating repair services to restore damaged, deteriorated or defective protective systems. Properly prepared and applied coating repairs help protect the substrate, support cathodic protection effectiveness and extend the service life of pipeline infrastructure.
