The Hydropower Industry and Epoxy Coatings


Hydropower is a renewable energy source that has been harnessed for thousands of years. Today, it is one of the most important sources of electricity in the world, and its use is only expected to grow in the future. One of the key components of the hydropower industry is the use of epoxy coatings, which are used to protect the machinery and infrastructure used in hydropower operations. In this blog post, we will explore the role that epoxy coatings play in the hydropower industry and the benefits they provide.

The Benefits of Epoxy Coatings in Hydropower Operations

Epoxy coatings are a popular choice for use in the hydropower industry because of the many benefits they provide. One of the primary benefits of epoxy coatings is their ability to protect machinery and infrastructure from corrosion. Corrosion is a major problem in hydropower operations because the equipment used is often exposed to water and other corrosive substances. Epoxy coatings provide a protective barrier that prevents corrosion from occurring, which helps to extend the life of the equipment and reduce maintenance costs.

Another benefit of epoxy coatings in hydropower operations is their ability to provide a smooth surface for water to flow over. This is particularly important in turbines, where a smooth surface is essential for optimal operation. The use of epoxy coatings can help to reduce friction and improve the efficiency of the turbine, which can lead to increased power generation and lower operating costs.

Finally, epoxy coatings are also resistant to high temperatures and can withstand exposure to UV radiation. This makes them an ideal choice for use in the harsh environments found in hydropower operations, where machinery and infrastructure are often exposed to extreme temperatures and intense sunlight.

Hydropower Industry Case Study

Belzona had the opportunity to improve the condition of a 60-year-old Kaplan hydropower unit that was showing signs of wear and was due for a full mechanical overhaul.

Operators at the Hydropower Plant grit blasted and cleansed the unit with solvent. Belzona 1111 (Super Metal) was used to smooth over the wear and cavitation in a full skim coat. Once cured, the Belzona 1111 (Super Metal) was sanded down to the required profile, and frost blasted. Two full coats of Belzona 1341 (Super Metal Glide) were applied. The coating can provide increased efficiency on new and refurbished equipment while also providing full corrosion and erosion protection while immersed.

Surviving 60 years with minimal wear is impressive. However, by using Belzona 1341 (Super Metal Glide), the unit can continue to operate for many more years, providing reliable service and cost savings over the long term. The use of this product can improve the unit's resistance to wear and tear and can also provide an additional layer of protection against environmental factors such as moisture and chemicals.

The Future of Epoxy Coatings in the Hydropower Industry

As the demand for renewable energy sources continues to grow, so too does the necessity for hydropower. This is expected to drive an increase in the use of epoxy coatings in the hydropower industry, as more and more equipment is needed to meet the growing demand for electricity. In addition, advances in epoxy coating technology are likely to make them even more effective at protecting machinery and infrastructure from corrosion and other forms of damage.

One area of particular interest is the development of epoxy coatings that are more environmentally friendly. As the world becomes increasingly concerned about the impact of industrial processes on the environment, there is a growing demand for coatings that are engineered with plant-derived ingredients. The Belzona Research and Development Team are currently in the process of formulating products made from bio-based materials that are produced from sustainable plant-based feedstocks, rather than the traditional fossil-fuel based ingredients.


Epoxy coatings play a critical role in the hydropower industry, providing protection against corrosion, improving efficiency, and withstanding the harsh environments found in hydropower operations. As the demand for renewable energy continues to grow, the use of epoxy coatings in the hydropower industry is expected to increase, and advances in technology are likely to make them even more effective. By working together, the hydropower industry and coating manufacturers can help to develop coatings that are both effective and environmentally conscious, ensuring a sustainable future for the industry and for the planet.

Hoist & Winch elevates success of large construction project

Hoist & Winch Ltd has recently completed a challenging project for one of the UK’s biggest construction companies involved in large-scale new home development projects. Faced with a demanding and highly technical brief, Hoist & Winch rose to the task, providing a turnkey lifting system solution to ensure complete success for its client.

The requirement was to install a concrete ceiling mounted 7.5t swl (safe working load) lifting beam and manual chain hoist into the basement energy room of a large new tower block. This development is part of a large-scale prestigious regeneration project providing 5500 sustainable new homes in North London. 

At the design stage, following formal tender and contract award, Hoist & Winch set about identifying the optimal solution. Due to restricted access into the basement area, the company decided to utilise a two-piece lifting beam design with an overall length of 7m. To join the two lifting beam sections, Hoist & Winch designed a central splice joint of bolted construction with a reinforced bottom beam flange.

In order to spread the lifting loads over a greater area of the concrete ceiling slab it was decided to mount the lifting beam via four intermediate cross members, each having a four-bolt/anchor fix into the concrete ceiling at both ends. Featuring a robust bolted construction design it was possible to deliver the lifting beam to site in fully dismantled form for ease of transportation and access.

M24 resin anchors with an embedment of 255 mm into the 400 mm deep reinforced concrete slab fixed the intermediate cross members directly to the ceiling for maximum security. 

​​​​​​​​​​​​​Continued ……

For approval by engineers at the main contractor, Hoist & Winch submitted design drawings and calculations for the structural design of the lifting beam and loading of the resin-type ceiling anchors. 

With the design approved, Hoist & Winch could progress to manufacturing, followed by delivery to site. Using building column positions as datum points, the installation line of the lifting beam was marked out while working from scissor lifts and an aluminium scaffold tower located on the upper mezzanine floor. A surveyor’s laser line initially identified the correct lifting beam position, prior to overlaying with red chalk to ensure accuracy for the duration of the installation work.

Raising the two lifting beam sections into position required the installation of eight 1t swl hand chain blocks, with each one suspended from M16 swivel eye bolts supported from flush-mounted anchored resin inserts drilled into the concrete ceiling slab. 

Following sample pull load testing, Hoist & Winch raised each lifting beam section into position using four 1t swl hand chain blocks. To raise the lifting beams to the full height and clamp them hard against the concrete ceiling slab ready for drilling, the company used two special lifting rigs per beam section.

The first lifting beam section manoeuvred into position also included the 7.5t swl hand chain block, which was rolled on to the lifting beam at low level using a 1t swl hand chain block temporarily suspended from local steelwork. Once both lifting beams were in position, Hoist & Winch joined the two lifting beam sections using the aforementioned bolted splice plate.

Next, the company undertook ceiling slab drilling operations and resin anchor installation for all 32 ceiling anchorpoints after very carefully cleaning each hole with a special heavy-duty internal brush and suction pump. Following the specified resin curing time, Hoist & Winch could tighten each anchor bolt to the required torque levels.

​​​​​​​​​​​​​Continued ……

The final installation and test operation was LOLER (Lifting Operations and Lifting Equipment Regulations) inspection of the lifting beam and manual chain hoist unit. This activity included dynamic load testing of the entire runway beam length with a 7.5t skid-mounted test load followed by 125% static proof load test in accordance with BS 2853 2011. 

“Working as a subcontractor for the company supplying and installing the plant and services in the basement energy room, we delivered an entire turnkey lifting system solution,” states Andy Allen, Director of Hoist & Winch Ltd. “At completion we provided the client with an overall project records and documentation package, before clearing all site equipment and undertaking customer handover. This project is just one of many exemplifying the meticulous, competent and professional approach that Hoist & Winch customers can expect from our highly knowledgeable team.”

Case study: Making safety culture visible at T5 with Scafftag


How to ensure shared information on the status of the scaffold is instantly available to all employees from all parties involved in a challenging T5 project? Read the full story!

No question, the scale of the T5 project is impressive and challenging. 16 major projects and 147 sub-projects make it one of the most talked about developments in the industry. But it is not only the size of the project that has attracted so much attention. The innovative approaches to safety employed have hit the headlines too.


BAA, which owns six other major UK airports as well as Heathrow, has focused on creating a proactive safety culture across all operations. This culture is intently participative rather than prescriptive. In 2000, BAA launched its renowned “One in a Million campaign to set a challenging target for the reduction of reportable injuries. As the name suggests, the campaign involves an ongoing benchmark target of only one reportable accident per million hours worked.

As an addition at T5, it has introduced its “Incident and Injury Free (IIF) programme. The idea of IIF is to make everyone on site responsible for safety - not only their own, but their colleagues. safety too.

The ultimate objective is to create an incident free site. Achieving this culture requires a strong degree of partnership amongst suppliers working on the project.

Specified Scafftag Systems

BAA already uses a custom designed Towertag system for managing its mobile towers on all other Heathrow terminals and its other airports. However, due to the scale of the project and number of contractors involved, an even wider range of Scafftag systems is in operation on T5.

Scafftag used by all contractors

The Scafftag scaffold tagging system has been specified by the T5 project team to be used by all contractors operating the vast structures which are in place. This helps to ensure shared information on the status of the scaffold is instantly available to all employees from all parties. It means that individuals are empowered to make informed decisions about the safety of the structure. This reinforces the culture of everybody taking ownership for safety. 056BB423-C03A-4600-B9D3-82C3012C9FFB.jpeg

Safetrak improves efficiency

The Safetrak system has also been adopted at T5 to move all scaffold inspection processes into a paperless, automated format. Inspection information is electronically transferred between the equipment tagging systems and handheld computers using RFID (Radio Frequency Identification) technology. The information is then synchronised and centralised by the Safetrak software.

Microtag adds protection

Beyond scaffolding, the Microtag system has also been specified to all T5 contractors to help control HAVS (Hand Arm Vibration Syndrome). A Microtag® is attached to portable tools subject to HAVS in order to indicate the maximum daily usage time and provide clear, up to date details of inspections.

The Microtag system is waterproof and ensures maximum durability in outdoor industrial environments. D22E73DF-DB73-4F93-A915-472C9D93DCA1.jpeg

Results that speak for themselves

BAA has invested major resources into safety on the T5 project. This has clearly paid off in noticeable results. T5s safety record is four times better than the industry average. Over 70% of the workforce believe that T5 is the safest place theyve ever worked. The statistics go on as Russell Hyam, Health, Safety and Environmental Manager for BAA, points out: Through IIF BAA has focused on shaping a positive force at T5 a safe working culture. The visibility of Scafftags systems plays a vital role in supporting this culture.

This probably goes some way to explaining why Scafftag systems have been adopted on some of the other major airports across the globe. These include Dubai International, George Bush Intercontinental (Houston, Texas), Toronto International, Melbourne International and Adelaide.

Raising the bar in challenging, large-capacity hoist installations

Supplying, installing, load testing and LOLER certifying a wide range of manual and powered hoist units, Hoist & Winch Ltd has extensive experience and expertise in all kinds of industrial lifting operations. However, certain projects require special know-how, such as the installation of large-capacity, electric-powered wire-rope hoists in challenging and restricted access applications. And yet even in these situations, Hoist & Winch has a proven methodology to ensure a high-performance, efficient, safety-certified outcome for customers.

Every hoist installation is different, and most generally present some level of challenge to overcome, typically relating to the dimensional clearances of the hoist unit or the logistics of general access conditions.

When the hoist unit’s dimensional clearances are particularly critical, Hoist & Winch Ltd carries out a detailed survey prior to manufacture, ensuring that the complete installation can perform the required tasks with sufficient operating clearance.

On some occasions, a pre-installation survey is required to check site/work area access conditions. Hoist & Winch Ltd will subsequently submit its Risk Assessment and Method Statement (RAMS) for approval by the customer prior to starting work. These documents detail the installation procedure, the equipment intended for use, and the hazards and risks associated with the various tasks. In addition, the documents will set out how it is possible to minimise or negate these risks.

A recent cement plant project involving challenging installation access conditions highlights how the capability and knowledge of Hoist & Winch Ltd proves extremely useful in delivering a successful outcome for customers.

                                                                                                                                                            Continued ……

This complex project involved replacing an obsolete, 10-tonne SWL (safe working load), electric-powered wire-rope hoist unit with 60m lifting height. The task was required ahead of the cement production facility carrying out extensive modification work to its pre-heater tower. The pre-heater tower is 100m high and the existing hoist unit was located at the 60m level on a monorail beam that cantilevers out of the building for approximately 8m. Both the obsolete hoist unit and monorail beam had been dormant for many years, which meant that Hoist & Winch Ltd’s scope of supply included the load testing and thorough examination of not just the new wire-rope hoist unit, but also the monorail beam.

Among the first tasks was to remove the existing wire-rope hoist unit, which weighed 3 tonnes. Hoist & Winch Ltd decided to cut this down in sections using gas-burning equipment as many of the hoist parts were badly seized and not easy to dismantle in the conventional way. Initially, the company removed these sections to a specially constructed scaffold work platform located below the hoist installation area. Each piece of the obsolete hoist was then lowered further to the nearest adjacent floor level 16m below using manual chain blocks for movement to the goods lift access located at that level.

Next, Hoist & Winch Ltd had to install the new hoist (weighing 2.2 tonnes) in part dismantled form. The company eased the difficulty of this task by installing a temporary 3-tonne SWL motor trolley mounted, air-powered chain-hoist unit on the monorail beam and raising the new hoist unit the required 60 m from the outdoor ground-floor work area. Hoist & Winch Ltd took great care with the preparation of the chain-hoist unit to ensure reliability during operation as any breakdown during the critical 60m lifting operation would require special access equipment to help resolve any issues. Hoist & Winch Ltd also carried out meticulous checks on the quality, volume and pressure of the air supply.

The next task was to raise the complete new hoist unit to the 60m installation level. From there, Hoist & Winch Ltd used the 3-tonne SWL motor trolley mounted, air-powered chain-hoist unit to transport the new hoist unit into the building and over the temporary scaffold work platform.

                                                                                                                                                            Continued ……

From this position - after first opening up the hoist unit trolley wheels wider than the monorail beam width – the company lifted the wire-rope hoist unit into position. To facilitate this task, Hoist & Winch Ltd deployed four 1-tonne SWL manual chain blocks suspended from each end of two specially fabricated lifting frames clipped into position on the top flange of the monorail beam.

The final tasks included electrical commissioning, assembling the hoist on to the monorail beam and the removal of all temporary lifting equipment. Hoist & Winch Ltd could then perform dynamic load testing of the new wire-rope hoist unit and monorail beam using a skid-mounted, certified 10-tonne test load prior to issue with a LOLER Thorough Examination report. As part of the dynamic load testing procedure, the outdoor cantilever section of the monorail beam was deflection-tested in accordance with BS2853 using a special long-range, outdoor-operation Leica laser mounted to a stable yet precisely adjustable tripod.

“Manufacturing and process plants tend to evolve over time, often compromising general access to existing hoist installations,” explains Andy Allen, Director of Hoist & Winch Ltd. “In other instances, legacy hoists fall into disuse and become obsolete. We’ve seen this on many occasions over the years, but with our in-house design, engineering and manufacturing skills, there is nothing we cannot overcome. If you are in this situation and could benefit from the input of an expert partner, please call for a no-obligation discussion about the potential solutions.”

AO launch funded gas apprenticeships for the first time

For Gas Safety Week, online electricals retailer AO announces that it has introduced fully funded gas apprenticeships for the first time to both grow its fleet of qualified engineers and invest in training. 

For the first time, the retailer has launched a fully funded apprenticeship aimed at upskilling both current employees and contracted drivers, which provides an accessible pathway to the Level 3 gas qualification. This runs alongside a new apprenticeship funded by the government levy, which is open to anyone with a full driving license.

Edward Knight first crossed paths with AO in 2018 when he was contracted for driver services alongside an electrical engineer. When this colleague announced he was leaving the business, Ed saw this as an opportunity to progress his own career in the industry. He said: “I moved onto being an electrical engineer for three years and then I was asked if I’d be interested in taking part in the gas apprenticeship.”

Before his career as a driver, Ed had pursued several different paths, including working as a chef in a hotel, working in a bakery and owning his own towbar fitting business. He’d always set his sights on an apprenticeship, however, the financial cost meant that this wasn’t an option until AO launched its funded apprenticeships. He said: “I’m really chuffed that I’ve had the chance to do it. I’ve been interested in training in gas for the last two years so this will open up new avenues for me.”

After a career at Gatwick Airport spanning 20 years, Jamie Taylor spent a year delivering for DPD before he crossed paths with AO. He had been contracted for driver services for around six months when the opportunity came up to do the gas apprenticeship via the retailer.

Jamie said: “I’d never been out with a gas engineer before, so I didn’t know what to expect! It’s been a lot to learn but I’ve really enjoyed the course so far - I particularly enjoy the flexibility of the shift pattern at AO since we get four days off for every four days on shift.”

Since being offered a place in the first cohort of funded apprenticeships, Ed has loved the opportunity to add another skill to his repertoire: “Gas training is a string to my bow at the end of the day and it’s another career for me. I’m 50 years old now and the opportunity has come at the perfect time as I’ve just moved into a new house. My advice for anyone considering an apprenticeship is to just go for it – you’ve got everything to gain and nothing to lose.”

During their course, apprentices take on all aspects of gas installation. Ed said: “The gas course is a lot more involved than I thought it would be and there’s a lot to learn – I get such a sense of achievement out of doing a good job.”

Running for up to 16 weeks, the fast-track programme consists of both online and classroom teaching, as well as on-the-road experience to quickly upskill participants. The AO funded scheme runs alongside an apprenticeship funded by the government apprentice levy that offers comprehensive training in driving a 3.5 tonne van, gas qualifications and functional skills across 16 months.
