Ultrasonic Thickness Measurement
Conduct Ultrasonic Thickness Measurements on high rise storage & pressure tanks reducing risk and time of scaffolding or rope access teams. The repeat ability is to within 50mm for re-inspections to ensure uniformity is adhered to and client receiving the most accurate data on the market today. Using the new RTK (Real Time Kinetic) drone with additional protection from transmitting obstacles such as power lines and metallic structures, eliminating the risk of the GPS signals becoming distorted. The reports are then compiled by our design team delivering professional results using AutoCAD.
To assist with BREEAM, thermal inspection can provide an accurate survey on building efficiency. Detecting heat and air loss, our team can aid in the integrity of developments.
We use multirotor UAVs to acquire high resolution aerial images. This imagery is processed using advanced photo grammetry software to generate ortho photos, digital elevation models and panoramic images of a site.
This type of imagery is commonly used for site design, health and safety inductions, evacuation plans, tendering information and as-built photography. All of this can be presented in a web based 360-degree virtual tour.
Our experienced pilots can get in close to structures for safe cost effective inspection delivering unique results and reports identifying potential defects, be it cracks, corrosion, paint integrity etc.
We can reduce costs by removing the requirement for large areas of scaffolding and improve safety by reducing the need for working at height and over the side work.
Being able to freely move around high and difficult to reach structures our pilots can execute inspections in little time with minimal risk.
Our technicians have completed many close visual, thermal flare inspections and surveys. We can inspect a flare while it is live and online, avoiding the requirement to shutdown, which means substantial savings are made during the inspection.
Inspections can include the condition of the flare tips, radiation shield, flare supporting structure, pipework, gantries and handrails. Our experienced technicians can provide detailed reports and recommendations.
Currently, drone inspections can cover up 2 turbines daily, reviewing each blade within anything from four to nine minutes. This compares to a manual inspection rate of a maximum 1 turbine a day.
To detect cracks more easily and quickly, we can inspect using thermal technology which show enhance defect detectability.
We can undertake UAV internal inspections of large tanks on operational vessels such as FPSOs, bulk carriers and tankers, as well as onshore oil storage tanks and other confined spaces including chimney stacks and thermal boilers.
UAV’s reduce the requirement for working at height and the need to send personnel within confined spaces, allowing us to undertake a safe first audit so that further inspection and maintenance can be prioritized.
Cooling Tower & Chimney
Using UAV technology, we capture a series of individual aerial images to cover the full external surface of a structure. Advanced photo grammetry software is then used to create accurate 3D models and highly detailed ortho photo mosaics of the chimney or cooling tower. The results allow the user to visually scan the full height and 360o model with defects accurately measured. Our team inspect the condition of the concrete or brickwork, mantle, lightening conductors, acid resistant coating and cap and highlight any potential dropped objects.
Our experienced pilots have extensive knowledge when it comes to inspecting storage tanks to EEMUA 159. Holding NDT disciplines, our pilots and technicians can inspect hard to reach areas using drones with LED lighting to assist with identifying potentially weakened areas and can carry out follow up Inspections.
Our pilots are experienced in the inspection of vessels using drones and ground inspections. Carrying out external visual inspections allowing our team to gather detailed digital and thermal images whilst in operation to aid in identifying internal lining defects without the need to shut down operations.
Pipelines can be difficult to inspect from start to finish due to difficult to access areas such as pipe bridges, jetty’s etc. Our experienced pilots have extensive knowledge in inspecting pipelines by foot and by drones. Our team can inspect pipelines using digital and thermal technology identifying integrity defects within insulation and piping defects such as cracking and corrosion.
We believe in delivering the most professional of services and it is why we ensure that the end product is always of the highest standard. When performing Ultrasonic Thickness Gauging the process is paramount to be repetitive and ensure that the exact locations are uniformly gauged as the previous inspection. Our Inspectors take measurements and send on to our design team to be put into an AutoCAD final report for precision.
Eddy Current Testing
Eddy Current Testing uses the principle of electromagnetic induction to detect flaws in conductive materials. An excitation coil carrying current is placed in proximity to the component to be inspected. The coil generates a changing magnetic field using an alternating current which interacts with the component generating eddy currents. Variations in the phase and magnitude of these currents are monitored either by using a second coil, or by measuring changes to the current flowing in the excitation coil. The presence of any flaw will cause a change in the eddy current field and a corresponding change in the phase and amplitude of the measured signal. In the case of Non-Destructive Testing (ND), these are displayed on an eddy current flaw detector as a distinct change in signal.
Dye Penetrant Inspection
Dye penetrant inspection (DPI), or penetrant testing (PT), this is a low -cost inspection method widely used to locate surface breaking defects in non-porous materials (metals, plastics, ceramics). DPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components. DPI uses capillary action where a low-surface tension fluid penetrates into clean and dry surface-breaking flaws. Penetrant may be applied to the test component by dipping, spraying, or brushing. After adequate penetration time has been allowed, the excess penetrant is removed and a developer is applied to draw penetrant from flaws, making indications visible.
Magnetic Particle Inspection
Magnetic particle testing (MT) is a non-destructive testing technique utilised to detect defects or discontinuities (such as cracks) at or near the surface in ferromagnetic metals such as iron, steel, nickel, cobalt, etc. Magnetic particle testing (as well as other non-destructive testing techniques) is primarily utilised in the industrial sector to test metal materials such as oil & gas pipelines and various metal machinery components to prevent failures or accidents. Some of the most common industries that utilise magnetic particle testing include petrochemical, automotive, aerospace and structural steel – just to name a few. In addition, magnetic particle testing may be utilised to inspect underwater structures such as pipelines.
Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterisation, and more. A typical UT inspection system consists of several functional units, such as the pulser/receiver, transducer, and display devices. A pulser/receiver is an electronic device that can produce high voltage electrical pulses. Driven by the pulser, the transducer generates high frequency ultrasonic energy. The sound energy is introduced and propagates through the materials in the form of waves. When there is a discontinuity (such as a crack) in the wave path, part of the energy will be reflected back from the flaw surface. The reflected wave signal is transformed into an electrical signal by the transducer and is displayed on a screen. Signal travel time can be directly related to the distance that the signal travelled.
From the signal, information about the reflector location, size, orientation and other features can sometimes be gained.
