Considering the imminent exponential growth of the hydropower industry, it is essential that an arsenal of strategies is implemented in order to raise the sustainability standards within hydropower facilities - driving the industry towards a net zero future. 

Of these strategies, protective coatings and repair composites have an important part to play. By intrinsically improving the integrity of key hydropower assets, these products help to accelerate the drive towards more sustainable hydropower facilities and, therefore, the decarbonisation of the sector.

The Carbon Footprint of Hydropower

While the environmental benefits of hydropower far outweigh fossil fuel alternatives, like most alternative energy sources, hydropower is not without its carbon footprint. Indeed, all energy sources, even renewables, produce carbon emissions in their lifecycle, due to the emissions caused by their manufacture, construction and operation.

While there are some hydropower facilities, such as Iceland’s Landsvirkjun, which have pledged to become carbon neutral, on average, the Intergovernmental Panel on Climate Change(IPCC) states that hydropower has a median greenhouse gas (GHG) emission intensity of 24 gCO₂-eq/kWh. This is the grams of carbon dioxide equivalent per kilowatt-hour of electricity generated allocated over its life-cycle. By comparison, the median figure for coal is 820 gCO₂-eq/kWh.

Hydropower Capacity Needs to Double by 2050  

The need to mitigate this carbon footprint somewhat ratchets up when considering the huge role hydropower is set to play in supporting a net zero emissions by 2050 pathway (in line with The Paris Agreement). 

In the International Energy Association’s (IEA) ‘Net Zero by 2050’ Roadmap (revised version 2021), the required growth of hydropower is colossal. The Roadmap states that hydropower capacity needs to ‘double by 2050’, positioning the industry as ‘[…] the third-largest energy source in the electricity mix by 2050.’

A Call to Modernise Aging Plants 

While it is essential that hydropower capacity ‘doubles’ by 2050, one way of increasing this capacity is by, what the IEAdescribes as ‘modernising ageing plants’. In fact, their Roadmapdetails how between now and 2030, USD 127 billion – or almost one-quarter of global hydropower investment – will be spent on modernising ageing plants.  

In regards to these ‘ageing plants’, according to the IEA, in North America, the average hydropower plant is nearly 50 years old and in Europe, the average is 45 years old. 

The report goes on to say how: ‘These ageing fleets – which have provided affordable and reliable renewable electricity on demand for decades – are in need of modernisation to ensure they can contribute to electricity security in a sustainable manner for decades to come.’

Extend Lifespan of Hydropower Assets with Industrial Coatings and Composites

Industrial protective coatings and epoxy repair composites play a fundamental role in ‘modernising ageing plants’, which in turn, supports the decarbonisation of the hydropower industry. 

By investing in this polymeric technology, aged assets can be repaired, protected and improved for the long term. This process successfully helps to mitigate the carbon footprint of hydropower facilities as it breathes new life into assets that would otherwise be decommissioned, replaced or sent to landfill. 

Companies such as Belzona (established in 1952) have a portfolio of protective coatings and repair composites that have been used to improve the efficiency and performance of hydropower assets for decades. 

Based on the level of erosion resistance required, the epoxy paste, Belzona 1111 (Super Metal) and composite repair polymer, Belzona 1311 (Ceramic R-Metal), can be specified for rebuilding damage and restoring efficiency in areas such as turbines, wicket gates and turbine casings. 

The efficiency improving capabilities of these systems can be demonstrably identified in the two-part epoxy coating, Belzona 1341 (Supermetalglide). With this high-performance coating, the efficiency of fluid handling equipment, such as pumps, can be increased by up to 7% on new equipment and up to 20% on refurbished equipment.

As seen in the graph below, in a study carried out by Leeds University, it was found that when compared to polished stainless steel, Belzona 1341 (Supermetalglide) was 15 times smoother.

The two-part polyurethane resin, Belzona 2141 (ACR-Fluid Elastomer), can be deployed in areas that are particularly subjected to high levels of cavitation, such as Kaplan turbine blades. This system offers an outstanding level of protection against cavitation at ultra-high velocities (up to 115 knots with no damage). 

Application of  Belzona 2141 (ACR-Fluid Elastomer) on Pelton turbine nozzle head 

Belzona’srange of polymeric systems can be specified in the following application areas, amongst others: turbines, penstock gates, generators, spiral casings, draft tubes, transformers, powerhouses, control valves, dams, stilling basins and spillways.

Mitigating Hydropower’s Carbon Footprint 

By investing in industrial protective coatings and epoxy repair composites, the lifespan of hydropower assets can be considerably prolonged. In turn, this supports more sustainable operations within hydropower facilities and, therefore, helps to mitigate the carbon footprint of the industry.

Danati Fire and Safety is a leading investigator of fires and explosions covering Southern Africa. Their first professional fire investigation was performed in 2003, and they perform an average of 250 investigations a year covering vehicles, structures and shipping vessels. The growth of Danati Fire and Safety can be attributed to verbal recommendations between insurance companies and loss adjusters in South Africa. A small number of private individuals may contact Danati Fire and Safety for private investigations either to counter a negative insurance claim or to simply satisfy their own curiosity.

After firefighters extinguish a fire, an investigation is launched to determine the origin and cause of the incident.  Investigations are carried out using a systematic approach combined with knowledge of basic fire science. For a fire to occur, there must be fuel, oxygen and an ignition source, which must be in the specific proportions. There is a very definite science to investigating fires, and experience really counts here.The fire scene must be carefully evaluated and documented to locate the source of the fuel and possible ignition sources. Potential causes will be ruled in or out depending on the evidence presented by the fire scene, burn patterns, and physical remains. Frequently, samples are taken and sent away for evaluation, which can be a lengthy and costly process.

Danati was first introduced to the ION Science Tiger by Impact Instruments and chose the Tiger over other similar products due to its lower cost, portability and technological superiority, as well as the excellent customer service provided by Lynda and her team at Impact Instruments.

Danati’s Lead Fire Investigator, Danny Joubert, has said, “The instrument is extremely sensitive and will almost always give some level of reading when it is exposed to fire debris. Having done so on numerous occasions, I can honestly say that there are many positive aspects to the Tiger VOC detector.

“It must be understood that this instrument does not provide a definitive test for the presence of a specific accelerant or ignitable fluid. What it does do is indicate where higher than usual concentrations of VOCs may be present, and this will then prompt the investigator to take appropriate samples for laboratory testing, as per the NFPA 921 guidelines.Without the VOC detector, the average investigator can only rely on an interpretation of burn patterns and their sense of smell to detect the possible presence of a VOC.

“The Tiger adds a new dimension, and has allowed a far more thorough screening of

debris to take place whilst the investigator is moving through the scene.

“The unit is very sensitive, allowing the investigators to disregard debris that might otherwise have been collected and subjected to expensive laboratory testing. Certified for use in explosive atmospheres, with high levels of sensitivity and resistance to interference from humidity or contamination, the Tiger is the only handheld instrument of its kind in South Africa, so it has allowed Danati bragging rights, which is always a morale booster!”

The biggest success of the Tiger for Danati related to a supermarket fire that was initially believed to be caused by an electrical surge following a period where the electricity was shut down.

The instrument was started up, and the investigator entered the building. The Tiger immediately gave a reading, turning left, the readings dropped, and walking further into the premises caused the instrument to give an alarm. This was the first audible alarm that the instrument had given, and the readings were extremely high. Standard human olfactory sensing could not detect anything above the normal stench of a three-day-old fire scene in a supermarket. Using the Tiger, the source of the alarm was found, and samples were taken. The samples were sent to a laboratory, and the intentional nature of the fire was put beyond any question.

The instrument shortened the investigation time considerably, and it was also noted that two other investigation firms were in attendance; their reactionto the Tiger was a combination of awe and jealousy.

In a hazardous environment, portable lighting must be engineered to prevent a spark from occurring and igniting any flammable vapors or mists in the area. The ATEX and IECEx Zone systems were created to classify the different danger levels in these areas.

Portable lighting must be carefully selected based on the most hazardous environment it may encounter since the situation may quickly change due to an accident, equipment failure, or malfunction. Therefore, it is critical to identify the Zone in which you will be working and the Zone you might find yourself in during an emergency. Let's take a look at the specific characteristics of each Zone.

Zone 0

Explosive atmosphere is always present. 

Zone 1

Explosive atmosphere is likely to occur during regular operations. 

Zone 2

Explosive atmosphere does not occur during regular operation or for a short period only; this is usually the result of an accident or other unusual operating conditions.

The safest option is to use equipment rated for the Zone you might encounter instead of the one you will be working in. A great example of this is the Nightstick XPP-5422G torch. This ATEX safety-certified Dual-Light™ torch is engineered to not release enough electrical or thermal energy under normal or abnormal circumstances to cause ignition, even in a Zone 0 environment. The Dual-Light feature helps users to regain the lost peripheral vision from a traditional torch, allowing them to see the immediate area below and to their sides, significantly reducing the chances of a slip or trip. 

The final thought to consider when purchasing ATEX equipment is the product's manufacturer. A single-source manufacturer ensures consistent quality and safety across an entire product line. This is especially important when buying hazardous environment safety lighting. Nightstick, the original creator of the Dual-Light torch and a global manufacturer of over 50+ intrinsically safe professional, portable LED lighting products sold in 70+ countries, exceeds industry standards in performance, quality, value, and user safety. Focus on completing your job confidently, knowing your equipment was designed and rated for the highest safety levels. Find the certification level you need at www.nightstick.com.

The Water Jetting Association, the member organisation for the water jetting industry, is to allow its courses to be delivered by training providers based outside the UK for the first time.

The decision will help meet growing demand for water jetting operatives based around the world to benefit from WJA training.

The WJA Training and Safety Committee approved the change, which was then ratified by the WJA Ruling Council at its meeting in November 2022.

A key ruling is that WJA-approved training providers and instructors based in other countries will not be permitted to deliver training in the UK.

WJA President John Jones said: “This is a significant and exciting decision for the WJA.Requests for our training to be delivered outside the UK have increased in recent years and we want to be able to meet that demand.

“Until now, our rules have required all WJA-approved training providers to be based in the UK. In most cases, this has required WJA-approved instructors to travel from the UK to other countries to deliver training.”

“Our decision means this no longer must be the case. If training providers and instructors meet our criteria and pass all our assessments, they can be approved by the WJA.

“That means WJA training can be delivered, for the first time, by both training providers and instructors based in any country around the world.”

The WJA is the UK member body for the water jetting industry. It represents water jetting contractors, hirers, equipment manufacturers, suppliers, and training providers, and works closely with other stakeholders, including asset owners and organisations concerned about water jetting safety.

Demand for WJA water jetting training is growing in many countries, most notably in the Middle East, North Africa, and Central Asia, which have significant oil and gas industries.

WJA Training and Safety Committee Chairman Steve Williams regularly delivers training in other countries. He said: “This is a positive move. Without it, the WJA would be unlikely to keep up with demand for its training courses.

“In the Middle East, for example, WJA training is highly valued because it is based on the WJA’s codes of practice that are recognised and respected for setting a clear standard for water jetting.

“Training providers and instructors in the Middle East, and other regions, will now be able to apply for WJA-approved status, which includes a process of ongoing assessment.

“This means more water jetting operatives will benefit from WJA training which can only enhance the safety and effectiveness of water jetting operations in those countries, which is a positive step forward.”

To become a WJA-approved training provider, organisations must join the WJA. This requires them to sign the WJA Professional Charter and meet its stringent financial and governance criteria, as well as undergo a rigorous assessment process.

Training instructors musthave a minimum of three years’ experience in water jetting, related to the practical modules they plan to deliver.

They must hold a current PTTLS or Level 3 award in education or training, or their equivalent, and a health and safety qualification, at least equivalent to IOSH Managing Safely.

As stipulated by the WJA’s standard operating procedures for training, they must hold a current WJA safety awareness certificate and the certificates for all practical modules for which they are competent to deliver.

Their formal application must be approved by the WJA’s Ruling Council. They must agree to a process of formal assessment, including a WJA assessor attending training courses.

Happy 2023! I thought as it was anew year I would take a break from updating everyone on the every changing UKCA Requirements and look at a few other scheme and Standards updates.

The IECEx Certified Equipment Scheme have published OD 290 - Harmonized procedures for IECEx certification of equipment, components and systems associated with the production, dispensing and use of gaseous hydrogen.

ATEX is an acronym for “Atmospheres Explosives” and refers to a set of European Union (EU) directives for the design of electrical equipment suitable for use in hazardous locations where an explosive atmosphere could exist. Typical hazardous locations include the more obvious places such as flour mills, coal mines, petrochemical plants, fuel transferfacilities etc. However, some not so obvious hazardous locations also include waste water treatment plants, saw mills, tunnels and underground passageways or any location where a build-up of naturally occurring flammable material (such as methane or dust) could occur.

In many of these locations there is a need for condition monitoring, for example by measuring temperature or vibration of rotating machinery. The equipment needed to do the monitoring must therefore be “intrinsically safe”, in other words it must be incapable of igniting an explosive atmosphere, should one exist. This is where ATEX comes in, as in order to be considered “safe”, equipment needs to be certified for use in hazardous locations. 

Definitions of areas subject to explosive atmospheres

The likelihood of an explosive atmosphere existing is dealt with by the definition of various zones, and for IECEx(Worldwide) & ATEX (European) standards the following zones are defined:

Zone 0 - an area in which an explosive atmosphere is present constantly or for long periods or frequently.

Zone 1- an area in which an explosive atmosphere is likely to occur in normal operation occasionally.

Zone 2 - an area in which an explosive atmosphere is not likely to occur in normal operation but, if it does occur, will persist for a short period only.

Figure 1 – Examples of IECEx and ATEX zones

Affordable intrinsically safe instruments for condition monitoring

Intrinsically safe instruments can cost many times more than their non-intrinsically safe equivalents. This is partly due to the increased manufacturing costs (e.g. additional safety components and encapsulation) but also due to the high cost of certification. However, Test Products International (TPI) believes it has introduced a real game-changer with the certification of the very affordable TPI 9080Ex.IECEx/ATEX certified for use in Zone 1 and with North American approval for Class I, Zone 1, the TPI 9080Ex is certified for use in hazardous locations anywhere in the world. 

The TPI 9080Ex uses industry standard BNC connected intrinsically safe accelerometers and offers on-meter analysis for detection of machine faults such as unbalance, misalignment, looseness and bearing wear. With full colour OLED display and Bluetooth communications, the TPI 9080Ex features colour coded alarms and zoomable on-screen vibration frequency plots with cursor readout. It can store lists (routes) of up to 1000 machines, each with up to 10 measurement points, with full waveform and frequency spectrum (FFT) capture. 

The included VibTrend PC based trending and reporting software has features normally only found on high-endsoftware such as automatic email notification of alarms and report generation.  The windows based software is totallyintuitive so it can be used easily and effectively by both expert and novice users to implement a full CBM strategy.  In-line with TPI’s philosophy of being the value leader, the TPI 9080Ex comes at the incredibly low list price of only £3,500that includes a full VibTrendsoftware license.

The Si124 range of acoustic cameras now detects air leaks from 2 - 65 kHz - and the small change means big operational improvements for industrial applications across sectors.

The Teledyne FLIR range of acoustic imaging cameras, the Si124, Si124-PD and Si124-LD, now offers an improved bandwidth range for detecting compressed air leaks in industrial settings. The change means that the industry-leading range can now detect leaks from anywhere between 2 to 65 kHz and adds crucial functionality to the previous peak bandwidth of 35 kHz.
While it may seem like a minor change, the operational impact of the improvements cannot be overstated: it means marked savings for industrial applications globally, reducing costs and improving reliability.

The improved Si124 range promises easier, more impactful inspections

The range of three cutting-edge Si124 models are now equipped to measure virtually all compressed air leaks in manufacturing settings - regardless of how small and seemingly insignificant. This unique range covering 63 kHz is scientifically the optimal sound spectrum range for detecting leaks, which occur on this measurable threshold. Detecting ranges outside of this spectrum actually detracts from long-term functionality as detecting background noise beyond 65 kHz can interfere with baseline readings and negatively impact leak detection.

Failure to detect air leaks can cost companies thousands of pounds in replacement costs for units that are not operating optimally, and can have a knock-on effect on production when parts are replaced and production lines forced into downtime.
Federico De Lucia, Team Lead of Condition Monitoring Specialists (EMEA Solutions) at Teledyne FLIR explains why this seemingly small change cements the Si124 range as operating across the optimum bandwidth for detecting compressed air leaks in industrial applications.

“Let’s look at, for example, a compressed air leak from a small hole of just 1.5 millimetres and on a network of compressed air at seven bars of pressure. Two years ago, with a price of €0.07 per kilowatt hour, that would have cost a company roughly €1500 (£1300) per year, if we assume an average operating time of 6000 hours.

“Now that the energy situation is more challenging, it means that costs may be three, four, even five times higher in some cases, which could be a cost of up to £7500 a year - which is a shocking amount simply for failing to identify a single small hole in a vital production component. This is staggering when you consider the scale of industrial manufacturing and the scope for leaks to crop up unnoticed.”

Tightness testing is an outdated model

“The EV industry is a particularly timely example of how acoustic imaging can be used to replace outdated inspection models, given the rising cost of energy on all fronts.

“This is because the batteries for electric vehicles must be hermetically sealed to ensure they hit operational guidelines and safety standards. They must be both airtight and watertight to keep dirt, dust and other external contaminants from penetrating the core components, which could cause the device to short-circuit and become a fire risk.

“Traditionally, these units were probed by mass spectrometers to identify foreign compounds within the casing or through the more rudimentary method of immersing the units in water to identify leaks by looking for air bubbles - which we call tightness testing - but this was incredibly impractical, as well as wasteful.

“Teledyne FLIR’s improved range of acoustic imaging can detect leaks quicker than this outdated model as well as identify much smaller leaks that are not visible to the naked eye, able to be heard by the ear, or even detected on traditional thermography. The improved bandwidth range of the Si124 ensures that operators are only focusing on the exact and specific frequencies that compressed air leaks can be detected on - and not wasting valuable battery power or AI functionality struggling to filter out avoidable background noise on higher frequencies.”

Lighter and more ergonomic than any other acoustic imaging camera for industrial inspections
As well as benefiting from the optimum range of bandwidth for compressed air leak detection, the Si124 range also offers clear advantages for inspectors in industrial applications.

The Si124 range is incredibly lightweight. In fact, it is almost 60% lighter than rival models on the market at just 1.25kg including the battery. This makes sure that they can be used with a single hand, freeing up the operator to carry out harder-to-reach inspections in challenging environments. The lightweight range can be used for up to two hours and can even be operated in a range of challenging industrial settings from between –10°C to 50°C (14°F to 122°F), making it one of the most robust models available.

The acoustic imaging camera range is able to detect problems up to 10 times faster than traditional methods, including detecting air leaks, minimising excess utility costs and making avoidable equipment failures in pneumatic machinery a thing of the past.

The range also has an agile AI which uses projective algorithms to estimate how much a detected compressed air leak will cost by evaluating the air lost in real-time, calculating the spend per kWh and displaying an expected saving per year. Critically, this ensures that inspectors have valuable evidence needed to justify any incurred repair costs across the production line.

The Si124 range also benefits from Thermal Studio: a FLIR-exclusive plug-in which is able to build reports with more than 100 images quickly with fully customizable templates, overlays, and formulas. It streamlines thermal imaging analysis and ensures that inspectors are able to analyse, edit, segment and edit thermal video.

The improved FLIR Si124-PD, Si124-LD, and the original Si124 Industrial Acoustic Imaging Camera models are available for purchase globally from Teledyne FLIR and its authorised dealers. To learn more or to

The use of components in potentially explosive atmospheres, such as in the chemical and pharmaceutical industries, agriculture, woodworking and the metal industry, is governed by strict standards. With its LevelEx Ex cable gland, PFLITSCH is breaking new ground in terms of safety and ease of assembly.

The LevelEx consists of just four parts, which are simple and safe to assemble and take up little space. A special feature of the gland: the sealing elements have a captive design and cannot be lost during assembly. The LevelEx is available in nickel-plated brass and stainless steel, each version in sizes M16 to M75, with NPT threads from 3/8" to 2 ½". Its large sealing range means that cables from 7 mm to 66 mm can be tightly sealed. Thanks to the silicone sealing insert, the glands can be used in applications in the temperature range from –60 °C to +130 °C. 

The compact Ex cable gland complies with protection types “Ex-db” for flameproof enclosure, “Ex-eb” for increased safety and “Ex-ta” for protection by enclosure. It satisfies the demanding requirements of protection ratings IP 66, IP 68 and Type 4X.

The international ATEX, IECEx, VDE, DNV, CCC, KCs and UL Listed certificates – the latter demanding very stringent requirements – granted verify that this PFLITSCH cable gland can be reliably used even under extreme conditions. In an industrial environment, a product can be either UL Recognized or UL Listed. The difference lies in the degree of compliance with UL requirements. In potentially explosive atmospheres, the complete set of requirements must be met.

In order to obtain ATEX and IECEx certification, the cable gland must pass an overpressure test conducted at 30 bar for 10 s, in accordance with EN 60079-1. The LevelEx was tested with a test pressure of 48.6 bar, which corresponds to a reference pressure of 32.4 bar if the gland is used at an operating temperature of –60 °C.
