Non-Destructive Testing (NDT)
Danholsen Global Services Limited (DGSL) delivers comprehensive conventional and advanced Non-Destructive Testing solutions for oil and gas, marine, fabrication yards, process plants, and infrastructure assets. Our inspections are designed to verify integrity, detect early-stage defects, and provide actionable data that supports safe, reliable operations.
We execute Ultrasonic Testing (UT), Magnetic Particle Inspection (MPI), Dye Penetrant Testing (DPT), Radiographic Testing (RT), Eddy Current Testing (ECT), and Visual Testing (VT) through highly skilled, certified personnel using calibrated equipment and controlled procedures.
Conventional NDT Services
Our conventional NDT programs cover welds, pressure boundaries, structural members, and rotating/static equipment. Each scope is delivered with method statements, traceable reporting, and clear acceptance criteria aligned to project specifications and applicable codes.
Advanced Inspection Technologies
For critical assets and high-consequence components, we deploy PAUT, TOFD, ECA, DRT, IRIS, PEC, LRUT/SRUT, MFL, PMI, VMT, and PWHT verification workflows. These methods improve defect characterisation, corrosion mapping, and remaining-life decisions with higher confidence.
Competence & Certification
Our inspectors hold globally recognised certifications including PCN, ASNT, ISO 9712, CSWIP, API, AWS, ACCP, IRATA, and NACE. This multi-standard capability allows Danholsen to execute cross-discipline inspections while maintaining strict technical compliance and audit readiness.
Integrity Assurance & Compliance
From pre-shutdown baseline inspection to turnaround support and post-repair validation, we combine technical depth with robust QA/QC to deliver precise results, safer operations, and full compliance documentation for client records and regulatory review.

Related Questions to Service
Which NDT methods are best for weld defect detection?
Method selection depends on weld geometry, material type, and defect mechanism. We typically combine VT with UT/PAUT or RT for volumetric coverage, and MPI/DPT for surface-breaking discontinuities to improve detection reliability.
Can Danholsen execute offshore and rope-access inspections?
Yes. Our team includes IRATA-certified personnel and experienced offshore inspectors, allowing safe access to elevated or difficult locations while maintaining full inspection quality and HSE compliance.
How do you ensure inspection data quality and traceability?
We apply calibrated equipment controls, competency-based personnel assignment, and documented procedures with complete report packs. Each inspection record is traceable to method, operator, calibration status, and acceptance criteria.
Do you provide advanced NDT for corrosion and in-service monitoring?
Absolutely. We deploy PEC, LRUT/SRUT, IRIS, ECA, and MFL workflows for corrosion screening and condition monitoring, enabling earlier intervention and better maintenance planning for high-risk assets.
Can you support shutdown campaigns and long-term integrity programs?
Yes. We support single-scope inspections, shutdown campaigns, and multi-year integrity programs with scalable staffing, clear reporting cadence, and technical oversight from planning through closeout.
