CYBERHAWK COMPLETES FIRST PROJECT IN TURKEY

Sector
Power Generation
Region
Europe

Our two man team, which comprised an industry qualified inspection engineer and an experienced turbine UAV pilot, mobilised to inspect 23 of the oldest turbines in the fleet to determine the levels of damage and asset integrity. Turbines in these particular sites require regular inspection as the region is subject to frequent storms and lightning strikes, therefore up-to-date condition assessments are crucial.

During the limited time that the turbines were taken out of operation, competent technicians (CT) were able to access the nacelle and hub while the drone inspections were being carried out. This allowed the CTs to make effective use of the turbine downtime to conduct required checks and other minor works. The advantages of using a drone for this inspection campaign include: Lower risk than traditional rope access inspection – avoiding the need to climb up and down the turbines whilst attached to ropes, and extended periods of working at height Non-contact – using an experienced drone pilot meant any potential contact with the blades was avoided, therefore removing the risk of damage Less downtime – the speed of inspection meant that turbine downtime was minimised, and the full inspection campaign could be completed quicker than using rope access.

Back in the UK, our inspection reporting team worked methodically through the visual inspection data to create detailed engineering reports for the client. Any priority areas were flagged up to the client while the reporting was taking place, so that repair works could be planned and targeted correctly.

Reports on all 23 turbines, blades and towers were delivered via iHawk, our cloud-based asset management software, which allows clients to view assets on a map-based interface, identify the severity of any damage or integrity problems using a traffic light colour coded system and drill down into detailed visual inspection imagery, which can be used to improve decision-making and maintenance planning.

Many wind turbine owners, operators and OEMs new to the world of UAV inspection are dubious about the accuracy and quality of data that can be achieved through this solution. We could tell you all about how we can size defects down to +/- 5mm accuracy, or position the defects to a few centimetres from the root and leading edge, but we thought a real-life example would be more interesting….

The interesting part, however, is that our UAV inspection identified a crack on the trailing edge of one blade which the inspection using a ground camera failed to pick up. Trailing edge cracks can be difficult to see and if not detected and monitored from an early stage, can become progressively worse, leading to structural damage and costly repairs.

In a recent project for a major OEM, Cyberhawk was tasked with inspecting blades at an onshore wind farm in the UK. The OEM was keen to compare our drone captured data to that from their traditional ground camera solution. Despite 25 knot (12.8m/s) wind speeds, our team mobilised to site and conducted the inspection in just a few minutes.

15

This example proves an important point. It demonstrated that an experienced UAV inspection team can not only match the quality of traditional inspection methods, but can actually identify defects which may not previously have been picked up – without requiring technicians to work at height.

CYBERHAWK CONDUCTS FIRST INSPECTION IN TRINIDAD & TOBAGO

As part of a client’s ongoing fabric maintenance campaign, Cyberhawk was appointed to conduct a detailed inspection of four offshore vents and two onshore flares.


CYBERHAWK CONDUCTS GENSIP COMPLIANT INSPECTION OF THERMAL POWER STATION

Sector
Power Generation
Region
Europe

Like many other thermal power operators, it conducts these inspections to the GENSIP Roofing & Cladding standard. This categorises the condition of area such as wall classing, patent glazing, curtain walling and roof decks. The standard looks to identify if these areas are intact or cracked, bent, corroded, broken, rotten or missing. The inspection findings must also be prioritised by severity of the defect to allow effective maintenance planning. For instance, does the defect present a remote risk, a possible risk, or a potentially hazardous event occurring in the next year, next few years or next 10 years.

The client approached Cyberhawk as it was looking for an alternative, non-intrusive inspection technique which could examine the building’s cladding and roofing and identify areas of corrosion, damage and potential detachment. This inspection was to meet the criteria set out by the GENSIP standard. Cyberhawk mobilised a UAV pilot and inspection engineer to site, who took just one day to conduct inspections of the external roof area and specific sections on the internal roof structure.

This type of inspection would traditionally be undertaken using a mobile elevated work platform (MEWP). The use of MEWPs requires close risk management, however; the HSE states that risks include entrapment, overturning, falling and collision.

15

Upon review of the GENSIP reporting template, Cyberhawk recommended using our internally developed reporting standard as this exceeded the requirements set out by GENSIP, which the client agreed to. The report provided highlighted the location of defects and areas which required further tactile inspection and/or maintenance.

This project not only highlighted Cyberhawk’s ability to quickly and safely collect inspection data using UAVs, but also demonstrated the quality of our reporting by exceeding an existing industry standard.

WORLD FIRST ASME CODE INSPECTION AT A US NUCLEAR PLANT

Sector
Power Generation
Region
North America

Although drones have previously been utilised in the nuclear industry this was the first time a drone has been used by the American Society of Mechanical Engineers (ASME) according to the Section XI Code. The Code refers to several American Concrete Institute standards for completing an examination and this inspection has been recognised within the nuclear industry as a best practice based on these standards. Cyberhawk has built a strong reputation for conducting UAV structural inspections in hazardous industrial environments, where safety is paramount, which saw the team become the preferred provider for this challenging scope of work. UAV inspection was also favoured to provide accurate data as it meant minimal risk to personnel, versus the working at height issues associated with conventional inspection and access techniques.

Moreover, the level of detail obtainable from traditional inspection methods is nowhere near what was achieved with UAV technology, capturing images of 100% of the dome surface to the ASME code standard with the results digitised into a 3D point cloud, that will allow direct digital comparison for any future inspections. Work was completed quickly, efficiently and according to the ASME code examination requirements, with an experienced pilot and inspection engineer working around the plant’s scheduled projects, without causing any interference. Furthermore, the magnetic interference of the nuclear plant meant that GPS signal was non-existent, so the whole project had to be flown by the pilot completely manually to conduct a safe inspection.

The alternative method of inspection would have involved using a man basket with a huge crane, which could take up to a week just to set up. In contrast, it took just one week for Cyberhawk to inspect both domes using UAVs, and generated cost savings of 300%.

15

It’s important to remember that drones collect a huge volume of data, however a high-quality engineering report can make all the difference. This allows the client to easily assess the condition of the structure and plan any maintenance based on the data. The final reports provided 100% visual coverage of the dome with exact sizing of defects and a 3D model of the structure. This was delivered to AEP through Cyberhawk’s cloud based iHawk visual asset management system.

As a UAV company that has extensive experience within multiple projects and sectors, Cyberhawk’s pilots and engineers have a varied and very experienced skillset. This allows them to successfully undertake projects of challenging nature, that no one has attempted before.

The work included close visual inspections of the leading edge, training edge, pressure and suction sides of each blade, capturing a complete visual record of each blade.

Cyberhawk mobilised a two-man team to undertake the UAV inspections. Traditionally, the inspections would have been carried out using rope access technicians, however this technique would have doubled man hours on site and involves working at height. Building on other recently completed inspections for Siemens Gamesa, Cyberhawk developed a tailored app to meet the client’s requirements. The requirement was a 25% overlap between images and no missing areas of the blade with processing and uploading on the same day as the inspection.

We were chosen to conduct this workscope thanks to our significant experience working for the world’s largest energy companies and experience of working in challenging environments, using UAVs to quickly acquire geospatial data in remote areas. Our unrivalled experience in aerial data acquisition and processing gave our client confidence that the survey results would be of the highest quality.

Using one of our fixed-wing UAV, with onboard RTK GPS positioning, we completed the full site survey in two days – a traditional ground-based survey may have taken over two weeks to complete. In addition to topographic data, we also provided high resolution orthophoto imagery with 3cm per pixel ground resolution.

Cyberhawk deployed a two-man survey team, comprised of a land surveyor and an experienced pilot, to survey a 230-hectare site of boggy moorland. Access on foot for a traditional land survey team would have been difficult and potentially hazardous, however aerial survey meant only limited ground access was required.

CYBERHAWK INSPECTS UK’S LARGEST CHIMNEY STACK

Sector
Power Generation
Region
Europe

Constructed in 1969 to withstand hurricane-force winds, the chimney stands 259 metres tall. At the time of construction, it was the largest industrial chimney in the world. It was essential for both chimneys to remain online throughout the inspections, meaning Cyberhawk was required to work onsite while the power station was fully operational, and around other day-to-day activities taking place on site.

Alternative methods for carrying out this scope of work, such as rope access, elevated cradles or scaffolding, would have taken weeks to complete the inspections and even longer when their erection and dismantling was included.

The two-man team, consisting of an experienced pilot and a certified inspector engineer, had to select specific flight positions to inspect the full circumference of the chimneys. The team also had to follow strict VLOS (visual line of site) protocols, which meant that whilst flying, the pilot had to remain in sight of the drone.

15

Cyberhawk’s solution not only mitigated the risks associated with this method, such as working at height, but reduced the inspection times as well. Normal timescales for this type of inspection would take more than 10 days per chimney, however, Cyberhawk carried out the inspection in just six days for both assets.

A number of imperfections consistent with the age of the structure were highlighted by the inspection. This allowed the client to become aware that structural maintenance was required and so had adequate data to outsource this work to a third-party provider. The results were delivered through Cyberhawk’s asset management software, iHawk. Utilising this software allowed the team to provide the client with detailed location and accurate defect sizing to +/- 10mm.

The high quality of images delivered through iHawk allowed Drax to provide structural repair companies with detailed visual data and in turn obtain accurate repair quotations. This information allowed the client to significantly minimise costs.

INTERNAL AND EXTERNAL CHIMNEY INSPECTION IN WASHINGTON STATE, US

In April 2017, Cyberhawk completed an internal and external inspection of a 250ft stack at a refinery in Washington State, US.

Power Generation
Region
North America

During the inspection, the stack’s downstream system was offline and open to the environment during turnaround maintenance activities. This allowed air ingress into the stack, creating vortexes inside the confined space, creating a very challenging environment in which to fly the drone. Furthermore low light, and the added challenge of zero GPS signal inside the stack, meant Cyberhawk’s pilots had to work with an extremely high level of precision during the inspection to ensure a successful end result.

Traditionally, this type of inspection is conducted using a manned basket attached to a large mobile crane, with a technician in the basket lowered into the internal part of the stack. Using this method would have incurred significantly higher costs. In addition, the crane would restrict other work activities in the refinery during a turnaround, creating a negative impact on timescales and potentially extending the shutdown.

UAVs were chosen as the preferred method of inspection primarily to reduce safety risk posed to personnel working at height, as well as the challenges associated with working in confined spaces.

15

Cyberhawk’s solution not only mitigated the risks associated with confined space and working at height, but also provided a detailed inspection report on the condition of the asset. This allowed the client to prioritise maintenance decisions and thus minimise costs. Finally, there was minimal disruption to other work activities in the refinery during the drone operations.

Thanks to the skill and ability of Cyberhawk’s pilots, the inspection of the critical components was successfully completed within two days. This compares with rope access which would usually take weeks to complete the same workscope.

Cyberhawk was asked by a major operator in Australia to conduct an internal and external visual and thermal inspection of a chimney stack at its nickel production plant. This project was the world’s first combined internal and external inspection of a stack using UAVs and the highest stack that has ever been inspected internally using a drone at approximately 426ft (130m), with the previous record being 400ft (100m) in Europe.

The inspection, which was completed in late 2016, was needed to identify any remedial works required to the stack during a scheduled outage in 2017. Analysis of Cyberhawk’s detailed inspection report, meant any actions required could be addressed during the shutdown which would allow the stack to continue operating safety to 2038.

The internal inspection and Cyberhawk’s inspection report uncovered a number of significant anomalies that were previously unidentified. Utilising Cyberhawk’s internal and external UAVs meant our engineers were able to assess the complete condition of the asset and resulted in the project being successfully completed.

15

Cyberhawk’s reputation of successfully inspecting confined spaces at industrial sites, along with our highly skilled pilots and engineers, saw the team emerge as the preferred provider for this challenging work scope. This inspection technique was also favored as it meant minimal risk to personnel, versus the working at height issues associated with conventional inspection and access techniques such as rope access or gantry basket.

The inspection methodology had also limited impact on plant production as the stack could be inspected by UAV by only shutting the bypassed dampers, which significantly reduced, but didn’t eliminate throughput of flue gas to the stack. For a manned entry to the stack to be undertaken a total plant/production outage would have been required to fully isolate the stack.

In 2016, Cyberhawk completed an internal steam boiler inspection for one of the world’s leading power companies in Bulgaria. UAVs were chosen as the preferred method of inspection primarily to reduce safety risk posed to personnel working at height, as well as the challenges associated with working in confined spaces. Traditionally, this type of inspection is conducted by rope access technicians who are suspended on ropes to inspect the boiler’s internal structure.

Bespoke safety procedures were put in place for this particular project, with Cyberhawk mobilising an experienced three-man UAV team consisting of a UAV pilot, inspection engineer and technician to ensure safe operations and high quality results. This allowed for a quick and safe inspection of the boiler.

The dark boiler environment, and added challenge of zero GPS signal, meant Cyberhawk’s pilots had to work with an extremely high level of precision during the inspection to ensure a successful end result.

The brief was to inspect more than 100 wind turbines throughout the company’s Scottish and Irish wind farms, with minimal loss of operational downtime and in timescales that would allow them to meet yearly inspection targets.

Cyberhawk’s asset management software, iHawk, allowed the client to quickly understand the condition of its wind farms and access high definition images of the entire blade surface of every turbine, as well as engineering commentary. These images also allowed the client to see the severity of the defect for themselves, and ultimately prioritise repairs and allocate budgets.

The work included close visual inspections of the leading edge, training edge, pressure and suction sides of each blade. Specific locations and sizing of each defect were essential in order to determine the damage and prioritise the maintenance required.

15

Traditionally, the inspections would have been carried out using rope access technicians, however this technique increases man hours on site and in turn, increases the risk and likelihood of injury. The use of UAVs mitigated these risks, and also meant reduced downtime for the client. One of Cyberhawk’s key USPs is the ability to inspect three to five turbines per day, compared with rope access which will typically only inspect one.

The client also reported that Cyberhawk’s technology made a significant improvement to project safety. On at least two occasions, turbines were not re-started on site after an inspection was carried out and revealed a safety critical defect.

Cyberhawk’s certified technicians and trained inspection engineers allowed the inspections to take place with minimal client supervision. The client reported a high level of confidence in the autonomous role given to the company’s inspection teams and based on this, as well as other positive feedback, Cyberhawk has been given the opportunity to perform a larger work scope in 2016.

Cyberhawk was tasked by Forewind to carry out a repeat drone inspection on the Dogger Bank offshore wind farm metrological (met) masts in April 2016. Cyberhawk was chosen due to our previous experience in successfully inspecting the met masts the previous year.

The scope of work involved working form the back of a vessel to capture detailed images of all the steel lattice members and the nuts and bolts on each flange joint. A detailed inspection report was then completed, allowing the client to quickly and easily understand the condition of their structures.

Dogger Bank is a particularly challenging offshore wind site as it is the furthest offshore wind project from UK shores at approximately 150 kilometres from the coast.

Cyberhawk’s two-man team, consisting of a highly trained UAV pilot and an inspection engineer, provided close visual and thermal UAV inspection of 12 cooling towers at Drax. Cyberhawk created a three dimensional model of each cooling tower to aid the visualization and accurate measurement of defects and to complement a comprehensive inspection report providing detail on the 360o condition of the structure from ground level to the mantle.

Typically, this standard of inspection would be carried out by a team of steeplejacks using cradle access suspended from the top of the cooling tower and would require a period of two to three weeks to complete.
