• Customer will make the appropriate stakeholders available to participate in meetings and discussions outlined in the applicable Order Form.
• Data Delivery Mechanisms – Customer may push sensor data to SkySpecs’ cloud following the requirements specified on Exhibit E or provide SkySpecs with the necessary access to install “Horizon Agent” software on Customer systems to push data to SkySpecs’ cloud.
• Sensor Data Stream Access – The Customer commits to granting SkySpecs timely and continuous access to all pertinent Sensor Data Streams and the corresponding system/network access. This access is essential to facilitate SkySpecs in delivering the agreed-upon services. The Customer acknowledges that any delay or interruptions in providing such access may result in service delays or interruptions, and hereby absolves SkySpecs of any liability arising from such delays.
• Changes Affecting Data Format or Acquisition – If the Customer makes any changes that affect data format, data acquisition, system configurations, or the integration mechanisms after the site(s) have been initially onboarded, additional paid support may be required to accommodate these changes. Such changes may include, but are not limited to, software updates, hardware upgrades, modifications to sensor configurations, or alterations to network access protocols. SkySpecs will not be responsible for service delays or interruptions resulting from these changes. The Customer agrees to provide SkySpecs with advance notice of any planned changes to allow for an assessment of the impact and the scope of additional services required.

ATTACHMENT B: CUSTOMER SENSOR DATA STREAMS

DATA STREAM TYPES

• Vibration sensor data – An online vibration monitoring system is designed to continuously measure vibrations in rotating machinery and equipment with the purpose of early failure mode detection. Vibration sensors are used to capture vibration data, which is sampled and post-processed by a data acquisition (DAQ) unit, which transmits the data to a central location for diagnostic analysis.
• SCADA data – Wind turbine SCADA (Supervisory Control and Data Acquisition) data refers to the comprehensive set of information collected and transmitted from a wind turbine’s monitoring and control system. This data encompasses a wide range of parameters and performance metrics, including but not limited to wind speed, turbine speed, power output, temperature, rotor position, and various operational statuses. A SCADA system can produce thousands of individual data channels, but SkySpecs will typically only use channels relevant for the monitoring task.
• Oil particle counter – Oil particle counter sensor data refers to the information collected by a specialized sensor designed to measure and analyze the concentration and size distribution of oil particles in a fluid. In the wind industry this sensor is commonly used for gearbox condition monitoring and to monitor the cleanliness and contamination levels of gearbox oil. The data generated includes details such as the number and size of particles, providing insights into the overall health and condition of the oil, as well as the machinery it is used in.

SENSOR DATA DELIVERY REQUIREMENTS

• Data delivery mechanisms: Customer may push sensor data to SkySpecs cloud following the requirements below, or provide SkySpecs with the necessary access to install “Horizon Agent” software on Customer systems to push data to SkySpecs cloud.
• Data formats: All data must be available in unencrypted and open data formats. The preferred format for data delivery is via machine-to-machine interfaces. This includes, but is not limited to, the provision of data through Application Programming Interfaces (APIs) or similar automated data exchange systems. Manual data access methods, such as single file downloads from web interfaces or any other non-automated data delivery methods, are not acceptable.
• Horizon Agent: SkySpecs utilize specialized software applications and scripts collectively referred to as “Horizon Agent” or “Agents” to be installed on customer infrastructure. These Agents play a crucial role when customers are unable to provide a machine-to-machine interface or lack the capability to extract data without the assistance of these specific tools. The purpose of these Agents is to facilitate the extraction of sensor data and seamless transmission of Sensor Data Streams to Horizon CMS. The customer shall provide the necessary access to deploy Horizon Agent software including but not limited to the provisioning of virtual or physical servers, access to customer networks, and relevant secure infrastructure in the wind turbine network.
• Vibration Data Channels and Measurements: The Customer shall deliver comprehensive data encompassing all Fast Fourier Transforms (FFTs), including spectra, cepstra, scalar values (indicators), and similar post-processed data. Raw waveform files produced by the system must also be provided, where available. Additional data channels, including but not limited to temperature, speed, and other measurements collected by the Condition Monitoring System (CMS), shall be included in the data delivery.
• Data Frequency – Optimal frequency of data delivery will match the frequency of data produced by the sensor systems which can be anywhere between 10min to 2weeks, depending on measurement, channel, and sensor system type. Practical limitations may constrain data delivery frequency and/or types of data delivered e.g. time waveform files (large files). Low frequency of data delivery causes risk of missed detections. Minimum frequency recommended is 1 time per day or higher.
• Data Density – The Customer is required to deliver data at the density at which the system produces it. For operational turbines that are producing at a level enabling the CMS to sample measurements, it is expected that a minimum of 1-5 FFT or Raw waveform measurements per day will be delivered. This frequency is a reference standard and may vary based on the operational status and configuration of the turbine and its CMS.
