Rope Robotics’ wind turbine blade repairs pay off in six months

-Preliminary business outcomes: return on funding after six months -Patented robotic first to supply sensible discipline care; offshore by 2024 -Rising must restore the lead; Robotic will increase capability amid US restore backlog -Advantages: 4 occasions sooner than guide at half the fee; security for technicians -Multi-use robotic with instruments and expert arm; distant management -Breakthrough in using viscous supplies -Future robots use AI for autonomous duties

AARHUS, Denmark, 6 February, 2023 – After greater than 18 months of operation, repairing greater than 150 rain-damaged onshore wind turbine blades on three continents, the patented robotic from Denmark’s Rope Robotics , the world chief in robotic blade upkeep, is making a comeback. funding for turbine homeowners in simply six months. In comparison with guide alternate options, the robotic can restore the blade 4 occasions sooner at half the fee.

More and more problematic, rain erosion injury can compromise blade aerodynamic efficiency and at worst can result in blade failure and expensive turbine downtime. The repairs supplied by Rope Robotics not solely restore turbine energy output however are fast, cost-effective and environment friendly in addition to secure for technicians to do in all however the worst climate circumstances. Beforehand, technicians needed to abseil from the nacelle to the blade and work with dangerous chemical compounds, a high-risk work surroundings that was time-dependent and costly.

“Rain erosion is already a critical and worsening subject with longer rotor blades creating tip speeds in extra of 380 kilometers per hour. Rain falling at that pace acts like a hailstorm. of bullets that, over time, injury the forefront of the blade,” explains Martin Huus Bjerge, CEO, Rope Robotics.
Environment friendly lead restore contributes to extending the lifetime of one of the costly elements of a wind turbine which accounts for about 25 to 30 % of the development price.

Improved annual power output (AEP) of three %; Offshore testing continues
Rope Robotics’ “BR-8” robotic can restore as much as 3 % power output in lower than a day per blade at half the price of guide options. First available on the market, Rope Robotics’ 9 robots have been in business operation for 18 months and have repaired greater than 150 wind turbine blades within the US, Canada, South Africa and Europe.

“Suggestions from prospects thus far confirms our calculations that after six months, the funding within the robotic restore service has paid off,” says Martin Huus Bjerge.

“The robotic has been effectively acquired particularly in international locations just like the US and South Africa the place there’s a backlog of repairs. So the robotic is an extra capability available in the market at present,” he added.

Making use of the outcomes from offshore repairs in international locations reminiscent of Denmark, Sweden and Germany, the restore and testing of offshore generators continues, in preparation for a business launch scheduled for the tip of the yr.

The core of the system is a robotic carrying visible sensors, which strikes the restore instruments with a versatile arm, with technicians monitoring the robotic from any location, onsite or remotely. .

Robotic raised by ropes and holding blade with vacuum system

On the website, the 150-kg robotic was first hooked up to ropes anchored to the nacelle earlier than it was raised about 100 meters from the bottom to the broken blade, which was fastened in a vertical place. A vacuum system permits the robotic to connect itself firmly whereas the motors are in a position to transfer throughout the blade. Utilizing an onboard high-resolution digital camera and laser scanner, the robotic inspects the floor, sends pictures to a distant operator, who diagnoses the injury and begins the restore course of in actual time.

Cleansing, sanding and restoring the blade

The three-phase restore course of begins with sanding the broken space, making use of the suitable pace and drive to create a sample that ensures floor roughness and geometry. The second instrument cleans the floor with a brush and alcohol to take away dust and grease. The patented dosing instrument applies the modern protecting (LEP) materials whereas the spreader instrument, additionally patented, recreates the optimum aerodynamic blade form, smoothing the fabric to pre-defined requirements. .

On-screen distant management and documentation

Remotely managed on-screen by a technician watching reside pictures, the robotic performs every step with excessive precision and consistency, thus making certain high quality. All pictures are recorded and function documentation, a worldwide requirement for wind turbine upkeep.

Granted two patents overlaying the robotic system, the tactic, the spreading instrument and the dosing instrument, the robotic took 5 years to develop and was launched in 2021.

“Maybe surprisingly, the largest problem is to create a transferring spreader and dosing instrument that may apply viscous materials precisely and flexibly to suit several types of blades. There are lots of variables to think about reminiscent of temperature , humidity and fluid dynamics. The absolutely functioning robotic that’s at present working in wind farms all over the world is a troublesome however satisfying activity,” concludes Martin Huus Bjerge.

Prolonged climate window and early coaching

After establishing the earliest injury, normally with drones, the wind farm or service supplier contracts Rope Robotics, which provides the robotic together with technician coaching and on-site help.

The robotic has been confirmed within the discipline at wind speeds of as much as 14 meters per second, relative humidity as much as 80 % and temperatures from 32 to 104 levels Fahrenheit.

Utilizing the outcomes from over 150 blade repairs already completed worldwide, Rope Robotics is investing in Synthetic Intelligence (AI) to supply autonomous repairs sooner or later.
