Inspection and Survey Services


EM&I have a wide range of conventional and innovative inspection and survey services.

We understand your business needs and focus on innovative inspection and survey methods which minimise operational and production disruption and reduce overall cost.

EM&I are different because our wider engineering and integrity knowledge means that we use the results of our inspection and surveys to provide you with reliable information and recommendations on which to base accurate management decisions.

EM&I invest in inspection methodology and are industry leaders of international Joint Industry Projects such as HITS (Hull Inspection Techniques and Strategies). We participate in other industry inspection bodies such as HOIS, the British Institute of Non Destructive Testing, Energy Institute, NACE etc.

EM&I inspectors meet and exceed the industry standard competency requirements for the task in hand. In instances where our innovative methods are ahead of the development of industry standards we have developed internal training and certification procedures to ensure personnel competency.

In summary, our objective is to provide you with the optimum inspection and survey solution.

Innovative Inspection

EM&I have developed a wide range of innovative and award winning inspection techniques as well as using the latest technology available on the market.

Details of EM&I’s proprietary methods are shown in the right hand sidebar on this page and further detailed information can be provided by contacting your nearest EM&I office - see under the Contacts Tab.

Other specialised inspection services include Pulsed Eddy Current, SLOFEC, Digital Radiography, Phased Array Ultrasonics, Time of Flight Diffraction and Thermography.

Phased Array

Ultrsonic Phased Array (PA) equipment produces accurate detailed cross-sectional images of     internal structures at rapid inspection speeds. PA technology uses multiple ultrasonic elements and electronic time delays to create beams that can be steered, scanned, swept, and focused electronically for fast inspection, full data storage, and multiple angle inspections.


Pulsed Eddy Current

Pulsed Eddy Current (PEC) was developed for the detection of corrosion under insulation (CUI). It allows the detection of corroded areas without removing the insulation. Using this method to indicate the affected areas can lead to significant cost reductions as fewer areas need follow-up and less insulation needs to be removed.





The Saturated Low Frequency Eddy Current (SLOFEC) inspection technique uses the eddy current principle in combination with a magnetic field and allows the fast screening of large areas of vessels, pipework and structures for internal and external wall thickness loss with minimal surface preparation.

The ability of the SLOFEC technique to inspect through different coatings and cladding types under high temperatures and through thick wall components means that it can be used as part of a Non Intrusive Inspection strategy.



Thermal imaging cameras detect radiation in the infrared range of the electromagnetic spectrum and produce images of that radiation. Thermography can be used for inspection tasks including those on rotating equipment, electrical equipment, pressure systems, insulated piping, storage tanks and vessels, looking for hot/cold spots, solids build up in vessels and piping, wet insulation etc.



Conventional NDT

EM&I can also provide conventional NDT and inspection services including ultrasonic testing, magnetic particle inspection, liquid penetrant inspection, radiography and eddy current inspection.


Our survey services focus on combining inspection, NDT and experienced engineering surveyors to assess the condition of your assets and provide you with accurate and meaningful reports. Survey scopes include:

Pressure Systems


Hazardous Area Equipment
