Non Destructive Testing (NDT)

Ultrasonic Thickness Testing (UTT)

Ultrasonic Thickness Testing (UTT) is a non-destructive inspection method used to accurately measure the remaining wall thickness of steel and other metallic components. It plays a critical role in assessing structural integrity, identifying corrosion or material loss, and ensuring compliance with class, flag state, and safety requirements.

At Midwest Marine Surveyors, we offer UTT as part of our comprehensive inspection services for vessels, tanks, hulls, pipelines, and critical infrastructure. Our qualified inspectors use calibrated, industry-grade ultrasonic equipment to perform fast, precise measurements—even in challenging environments.

UTT is essential for:

Hull and deck plate thickness assessments
Internal structural member inspections
Monitoring corrosion in tanks, voids, and ballast spaces
AMSA DCV statutory survey requirements
Insurance and pre-purchase evaluations

All measurements are recorded, documented, and presented in a clear, easy-to-understand report, complete with detailed readings and recommendations where required.

Whether as a standalone service or part of a broader condition survey, our UTT inspections help clients manage risk, maintain compliance, and support effective maintenance planning.

Thermal Imaging Inspections

At Midwest Marine Surveyors, we offer specialised thermal inspections for both the energy and shipping sectors, helping clients reduce risk, avoid costly downtime, and ensure compliance with operational and safety standards.

Shipping Applications:

Main engine, gearbox, and exhaust system assessments
Electrical panel and switchboard fault detection
Heat loss and insulation performance checks
Tank, bulkhead, and pipework inspections for thermal anomalies
Fire risk reduction through early identification of hot spots

Energy Sector Applications:

Solar panel string and cell temperature monitoring
Wind turbine gearbox and bearing heat profiling
Substation and transmission line fault detection
Transformer inspections and thermal load assessments
Condition monitoring for remote or hazardous sites using RPAS (drones)

Why use thermal imaging?

Zero downtime required—assets can remain operational
Early warning system for electrical and mechanical failures
Safer inspections in high-risk or inaccessible areas
Enhances predictive maintenance programs
Provides clear, visual evidence in support of audits, insurance, and compliance

Each inspection includes a detailed report with annotated thermal images, temperature readings, and prioritised recommendations for repair or monitoring.

Dye Penetrant Testing (DPT)
Dye Penetrant Testing (DPT) is a non-destructive testing (NDT) method used to detect surface-breaking cracks, porosity, and other discontinuities in welds, castings, and machined components. It is especially valuable for identifying fatigue cracks or stress failures in components subjected to harsh marine and industrial environments.

At Midwest Marine Surveyors, we offer DPT as part of our structural and welding inspection services—ensuring the integrity of critical components across the shipping and energy sectors.

Applications include:

Weld inspections on ship hulls, tanks, and structural reinforcements
Crack detection in offshore platforms and support structures
Assessment of crane booms, lifting points, and load-bearing frames
Component integrity checks in engines, shafts, and piping systems
Fabrication QA/QC for new builds and refits

Why choose Dye Penetrant Testing?

Simple, fast, and highly effective for detecting surface flaws
Suitable for a wide range of ferrous and non-ferrous metals
Requires minimal surface preparation and equipment
Ideal for in-service inspections or during planned maintenance
Provides documented visual evidence of defects

All inspections are performed by qualified personnel in accordance with relevant international NDT standards, and results are documented in a detailed report with photographs and repair recommendations where applicable.
