    • TEAMER: Riverine Hydrokinetics Torsional Cable Testing

    Metadata Updated: February 13, 2026

    BladeRunner Energy has developed a unique debris-resilient rotor that is uniquely suited to applications in remote Alaska rivers. Their unique topology couples a debris-resistant axial flow rotor to a floating power take-off (PTO) housing via a composite torsional cable. This torsional cable provides transmission of torque from the rotor to generator while allowing bending to facilitate rotor translation, pitch, and yaw in response to interaction with large debris. The cable will be submerged in water and acted upon by time-varying torsional and axial loads provided by hydraulic actuators. These loads are based on loading data collected during field testing, with the goal to accumulate cycles equal to extended of field operations. This data provides insight on the evolution of torsional cable stiffness over accumulated cycles and enable validation of cable structural models.

    This data is from cyclical simultaneous torsional and axial loading on a torsional cable to simulate loading encountered during use as a driveshaft on a current energy converter (CEC). The torque and tension fluctuation due to changing inflow conditions in rivers. This testing accelerates the load cycling to investigate stress-strain and fatigue properties of these cables for this application.

    This submission includes: - Matlab code to process cable raw data and produce plots within the final report - Raw cable data - TEAMER Post Access Report

    This project is part of the TEAMER RFTS 12 (request for technical support) program.
