Modern Mechanical Engineers: "Let us optimise the design of machinery & Equipment with minimum factors of safety to minimize costs; we can succeed because we have modern Finite Element design software." Reliability Specialist: "Your are failing in this philosophy. Learn from the earlier engineers of the past 100 years of Mechanical Engineering who added large safety factors to all machine components both static and rotating. No less than FS=2.0" Loss of Tension is highly tied to original joint design, and of course original preload of fasteners. Many possible design contributors to the failure in the video are typical in such failures: 1- Undersized flange thickness. 2- Undersized bolt diameters gives reduced joint preload. 3- Using M12.9 rating Fasteners. Not reliable. 4- Not specifying exact quality requirements for the Bolts & Nuts regarding mettalurgy. Some Bolts in Industry come from low cost, low quality sources. 5- Bolt holes excessive gap to bolt shanks. Lack of thick, hardened steel washers. 6- Lack of Nut Locking. 7- Lack of proper joint flange flatness and smoothness requirements. 8- Fatigue resistance of joint is not built-in by design. It is subjected to Joint flange deformation at high winds. 9- Flanged joint design of this very critical application must include a proven method of accurately knowing the bolted members actual preload at installation, to within 15% error maximum. Not the turn of nut methods and other primitive solutions. Maintenance function is not to solve Equipment Design defects; it is there to provide a Quality Preventive Maintenance function at reasonable cost, and at wide time intervals.

Structural damage evaluation and advanced life assessment are crucial aspects of preventive maintenance within the wind energy sector. Wind turbines operate in challenging conditions and are exposed to complex loading conditions, such as wind & temperature fluctuations and vibrations, which can degrade the structure over time. Inadequate maintenance and oversight can result in severe damages, leading to substantial downtime, expensive repairs, and potential safety risks. A recent incident involving a wind turbine failure in Spain serves as a stark reminder of the consequences of neglecting proper maintenance practices. At Ilosta, we recognise the significance of proactively identifying and rectifying damage to wind turbine structures. We employ cutting-edge technologies, including machine learning algorithms and tailored damage evaluation analytics, to detect and pinpoint all damages on a detailed 3D model of your asset. This approach facilitates swift and precise identification and measurement of emerging issues. Our advanced life assessment services offer you comprehensive insights into the condition of your structures, empowering you to make informed decisions regarding maintenance and repairs. By leveraging our innovative solutions, you can mitigate the risk of catastrophic failures and prolong the operational lifespan of your wind energy assets. Don't wait until problems escalate. Contact us today to discover more about our damage evaluation and advanced life assessment services and enhance the performance and longevity of your wind energy assets.

Constantly look, it is necessary to comply with the rules of continuous innovation and occupational health and safety

In all wind sites where the tower flange presents a clean slate, as shown in the video below, and where the Root Cause Analysis (RCA) consistently indicate blade failure as the source of system imbalance, a thorough review is warranted. It is imperative to acknowledge the substantial likelihood of bolt torque or fatigue risk across the remaining population. #flangedconnection.

Bad calculation on cantilever beam, this bad, poor design

Like some sort of futuristic military drone – it behaves remarkably like a kite underwater. It uses lift generated by tidal flows to fly patterns faster than the currents, harvesting renewable energy. Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods. Although not yet widely used, tidal energy has the potential for future electricity generation. Tides are more predictable than the wind and the sun. These are by no means small kites – the Dragon 12 needs to be disassembled to fit in a shipping container. It rocks a monster 12-meter (39-ft) wingspan, and weighs no less than 28 tons. Tethered to the seabed. The narrow channels between the Faroe Islands accelerate tidal flows, creating an ideal location for tidal energy projects. all comes down to power generated versus cost of deployment....shall await results 🤔👍 #tidalenergy #tidal #renewableenergy #renewablepower #energytransition #decarbonization #climateaction #climatechange #energysolutions #energysecurity https://lnkd.in/euj8RNeJ

How can steel deformation be measured? How often should the main components of turbines be replaced?

Structural engineering does matter ....

🚨 The tip of the iceberg 🚨 This one 👇 is a quite fascinating article, as it provides the clear sense of the massive complexity behind a new #energy industry - in this case wind. The article from Anca Gurzu from Cipher (available here https://lnkd.in/eqPzn_N5) shows how the realization of a #renewable plant is actually just the tip of the iceberg and how behind it there is an articulated and quite complex industrial system. The case for wind is quite striking. And here size matters because - as the article emphasizes - the dimensions of wind turbines and their blades make the biggest existing Airbus plane ✈️ to look like a small thing… The implications of wind turbines getting gigantic are quite important and go well beyond the energy sector. Everything is impacted: ports, roads, ships, trucks, infrastructures in general, etc.. This reminds how the destiny and success of a new #technology hinges on multiple aspects and requires combination and efforts on several fronts Innovation and cost reductions are fundamental prerequisites, but alone might not be sufficient. The entire supply chain needs to work in a fluid and harmonious way. Likewise, the coordination between very different #business sectors and - very importantly - integration among different parts of the institutions (as not every item is under energy ministry responsibility) are a critical piece of such gigantic revolution.
