Prometeo, the Offshore Rover by AXIST: A Breakthrough That Reinvents Mono-Pile Flange Measurement
In the world of offshore wind, precision is non-negotiable. Even the smallest deviation can lead to deformation, reduced performance, and costly corrective interventions. Measuring the flange of a mono-pile immediately after piling is one of the most critical moments in the entire installation process. Until now, it required long execution times, highly specialized personnel, the use of a second vessel, and—most significantly—the construction and removal of temporary platforms for every single mono-pile.
AXIST has developed a solution that radically changes this scenario: an autonomous metrological Rover designed specifically for offshore conditions, capable of completing a flange inspection in just thirty to forty minutes.
A Challenge Born at Sea
Performing metrological measurements in offshore environments has always been both a technical and logistical challenge. After piling mono-piles remain at sea with no platforms or safe access for operators. Environmental conditions are unpredictable, and the high costs of installation vessels demand extremely rapid interventions.
Until recently, verifying flange quality after piling required building an internal access platform, installing it, sending specialized personnel to perform the measurements, and then dismantling it. This costly and slow process forced the installation vessel to remain on standby for the entire duration of the inspection.
Prometeo—the Rover developed by AXIST—was created precisely to eliminate this complexity. Transported aboard the installation vessel, it is placed on the mono-pile flange using the crane immediately after the removal of the hammer. From that moment onward, the entire inspection is carried out automatically, remotely, and safely.
