Rotor Blade Maintenance

Boost your blade maintenance activities with Power of Less 

Staying profitable in a challenging market

The wind industry faces demand to increase durability, which influences service providers and the entire value chain. That’s why it’s essential for you to get the most out of every maintenance job. But that’s not easy when you consider challenging site conditions, a limited maintenance season, and complicated application processes.  

Focusing on blades is central to meeting the challenge as many older wind turbines have inadequate blade protection, and damaged or eroded blades cause poor aerodynamics. It is estimated that leading edge maintenance contributes to more than 50% of blade maintenance costs*. LEP protection is therefore key to increasing your AEP while ensuring benefits from longer service intervals and lower servicing costs.

Let Power of Less boost your maintenance activities

The Hempablade range of coatings is a best-in-class LEP protection that delivers better protection and performance with less material and waste and shorter application and repair times.

Outstanding LEP protection

Hempablade Edge 171 is your key to reducing your customer service times and complexity. This best-in-class LEP protection system also offers the market’s best RET to DFT. Put through over 600 exhausting test sessions during development, it delivers an impressive level of quality and reliability. 

Strong performance, higher service intervals

There are many benefits to choosing Hempablade Edge 171. Due to its long protection lifespan, it extends the time between service and maintenance intervals, reduces associated costs and increases turbine uptime.  

The coating is applied in a thin layer to the blade surface, and its superior protection performance at the lowest DFT thickness in the industry impact on the blade’s AEP performance.

Straightforward, fast application

Hempablade Edge 171 is efficient to apply and repair. It offers a wide application window that extends the maintenance season. It also offers one of the lowest DFT values of any liquid LEP in the market.

This lowers paint consumption, reduces application time and cuts drying time, so you can coat more blades in each shift. And, with simple application with brush or roller, you get a high-quality finish – fast.

Benefit from our in-house Rain Erosion Test facility 

At Hempel, we have our own in-house DNV GL RP-0171 compliant RET facility. And we’ve put Hempablade Edge 171 to the test in more than 600 exhaustive test sessions and assessments. This not only ensured the optimisation of its development and the LEP validation process, but it also means you can be sure it is proven to protect against rain erosion in the toughest conditions.

These rigorous tests culminated in a product that extends the intervals between scheduled maintenance, resulting in more turbine uptime and reduced operational costs.
