PRECISION AND ACCURACY ABOVE ALL

RENEWABLE

We provide 3D dimensional inspection consultancy and products related to the metrology industry

Get In Touch

Energy transition is happening now and at ALTO we know very well and we want to be part of the change.

We have developed and implemented an advanced dimensional inspection solution for wind farms both on-shore and offshore.

Our metrology solution includes survey of mono-pile transition pieces flanges and virtual assembly to make sure each part fits properly including the J-tube.

ALTO has extensive experience in other energy sectors like hydro or nuclear power plants, we use our know-how and facilitate technology transition into the new renewable challenges.

TP -Transition Piece Flange Inspection

The transition piece is a fundamental element that requires accurate surveying, which can be performed with a laser tracker or photogrammetry. .Utilising laser trackers or photogrammetry ensures rapid and fully traceable measurements, eliminating human error.


BCD, BHD, ovality, flatness, bolt hole orientation, and flange tilt are measured and promptly reported in a 3D report.

Monopile & Jacket Flange Inspection

During monopile and jacket fabrication, particular attention should be addressed to can ovality and assembly straightness. The survey is performed with a laser tracker, not only because of the accuracy but mainly for the fast acquisition. All the points of a can be measured in a few minutes, and a 3D report and dimensional analysis can be done on-site or later in the office. The data can be used anytime for a virtual assembly exercise.

Matching Excercise

At ALTO, we perform dimensional inspection surveys using advanced technology and software. All the measurements are 3D digitalised, and a virtual assembly simulation can be generated as a result of the study.
Multiple elements of the same assembly are measured and digitised at different moments and places, and then virtually assembled to predict potential misalignments, gaps, or collisions that need to be rectified before the physical assembly takes place.

Offshore Flange Inspection

ALTO has developed a unique combined solution using laser tracker and photogrammetry to measure the transition piece bolt hole (TP-BCD) without removing the cover. Our innovative mathematical solution enables PCD inspection without cover removal, whether during bolt tightening or at any stage. The measurement can be conducted by the client or any supplier, and ALTO can remotely run the algorithm and provide a comprehensive report on the flange and PCD condition without requiring direct measurements.

Offshore ROVER

Introducing the Prometeo Rover, a cutting-edge creation by ALTO and AXIST Robotics, tailored for offshore flange inspections. This advanced rover is delivered via crane and autonomously lands on the monopile flange, equipped with three high-precision scanners. These scanners meticulously gather data to assess the overall condition, local flatness, run-out, and tilt of the flange. But that's not all—Prometeo goes above and beyond with GPS and compass functionalities, enabling accurate positioning and reporting of true north during installation. It even provides insights into monopile inclination post-installation. Equipped with an integrated camera, Prometeo offers visual inspection capabilities, ensuring thorough assessment of the flange's condition.
Operating in winds of up to 16 meters per second and capable of landing in rough seas, this rover excels even in light rain conditions. To maintain pristine conditions for inspection, Prometeo features a built-in blower and wiper, ensuring clear visibility of the flange surface throughout the inspection process. Experience the future of offshore inspections with Prometeo—reliable, versatile, and engineered for excellence.
