our vision:

Contribute to a sustainable world with assured performance of Airborne Wind Energy Tethers



Rope/tether design:

Assured performance starts with a optimal rope design. Addressing all rope system failure modes and location specific requirements, the best fit for purpose rope design can be worked out taking into account the desired operational lifetime, minimal drag (lowest diameter) which will lead towards minimal cost of energy. The maintenance and replacement periods can be tuned to lowest cost of energy.

Quality assurance for rope:

To enable third party certification of the rope/winch system the rope quality needs to be assured of every meter of rope. Recommendations can be made for the rope specification and acceptance criteria to the rope that need to be met. The rope production can thus be checked and validated by third party wittnessing.

In situ rope monitoring device, RLM system for predictive maintenenace:

The RIGO ROPES Rope Lifetime Monitoring (RLM) system is especially developed for AWE systems. Based on a multi failure mode algorithm the monitoring device will make a proper judgement on the safe and reliable operations. The RLM system will be able to plan maintenance intervals and initiate needed replacement. Every segment of the rope is locally monitored and the most damaged area is identified while alarm setings can initiate maintenance actions. The attributed damage is tension weighted and takes into account most relevant failure modes: abrasion, bending fatigue and tension  

The RLM system is developed together with with an Industrial Automation partner.

Assurance cases for system performance:

Insurance companies demand that risks are reduced to a minimum. RIGOROPES has developed a method to claim safe and reliable use of the tether system that enables technology qualification, certification and insurance. Based on an extensive FMEA evaluation, mitigations will be put in place and tests will be proposed to confirm the mitigation.
