A system and method for performing a task on a LPS of a wind turbine includes a robotic testing device having a plurality of clamping arms and a LPS test probe coupled to a robotic end effector. The robotic testing device can be positioned around an outer perimeter of a rotor blade of the wind turbine. A cable, coupled to an up-tower anchor point, is attached to the robotic testing device and extends between the anchor point and a support surface. A lightning receptor of the LPS is between the up-tower anchor point and the tower support surface. As the cable is displaced, the robotic testing device moves to a position at which it is clamped to the rotor blade, adjacent the lightning receptor. The end effector moves to position the test probe in contact with the lightning receptor to conduct the test on the LPS.

Systems and methods for maintaining wind turbine blades

A system and method for inspecting, repairing and upgrading wind turbine rotor blades of a wind turbine. The system including deploying one or more cables via an unmanned aerial vehicle (UAV), a balloon, a ballistic mechanism or a catapult to position the one or more cables in draping engagement with a portion of the wind turbine. A climbing robot is positioned to ascend the one or more cables and perform a task related to inspecting for indications, repair of indications or upgrading the rotor blade. A slave robot system, disposed at the base location and anchored to the one or more cables, provides modulation of the cables for positioning of the climbing robot relative to the wind turbine as it ascends and descends the one or more cables. After completion of the task, the climbing robot descends the one or more cables and the cables are removed from the wind turbine.

System and methods may evaluate and/or improve target aiming accuracy for a sensor of an Unmanned Aerial Vehicle ('UAV'). According to some embodiments, a position and orientation measuring unit may measure a position and orientation associated with the sensor. A pose estimation platform may execute a first order calculation using the measured position and orientation as the actual position and orientation to create a first order model. A geometry evaluation platform may receive planned sensor position and orientation from a targeting goal data store and calculate a standard deviation for a target aiming error utilizing: (i) location and geometry information associated with the industrial asset, (ii) a known relationship between the sensor and a center-of-gravity of the UAV, (iii) the first order model as a transfer function, and (iv) an assumption that the position and orientation of the sensor have Gaussian-distributed noises with zero mean and a pre-determined standard deviation.

In one aspect, a system for estimating fatigue damage in a riser string is provided. The system includes a plurality of accelerometers which can be deployed along a riser string and a communications link to transmit accelerometer data from the plurality of accelerometers to one or more data processors in real time.

The number of sensor locations is small relative to the length of a deepwater riser string, and a riser string several miles long can be reliably monitored along its entire length by fewer than twenty sensor locations.
