Retrofit & Monitoring

1 2 Increase Turbine uptime with TCM Retrofit & Monitoring In an industry that requires maximum uptime to generate profitability, it is easy to see how downtime can mean the difference between success and failure. Turbulent wind conditions subject turbines to damaging structural vibration levels and peak load stresses on drivetrains, gearboxes, and generators. If left unchecked for extended time periods, it can lead to severe equipment failure. Our TCM system allows you to Predict, plan and prevent, and thereby minimize aggregate damages, and do repairs uptower. TCM Business Value - Protect your Assets and Optimize Cost of Energy Knowledge and experience from more than 17,000 wind turbines are embedded in our hardware, software, and technology. With 80% of offshore turbines equipped with TCM, isn t it time you found out why? Turbine manufacturers and utilities alike know the importance of protecting their assets. With TCM, we promise you a proactive maintenance plan that will help you secure your wind assets well into the future. TCM increases productivity and profitability. Revenue and cost are directly connected to the wind farm s performance. The Turbines have to be avaliable to generate when there is wind and all O&M activities should be planned around this avaliability. Subsequently, it is important to understand the factors affecting the turbines availability, and manage them effectively with minimum financial risk. The TCM System gives you a complete overview of the condition of turbines in all wind farm sites. It will help you increase wind turbine production by prevention of costly breakdowns. Reduce repair costs and improving cost efficiency of maintenance and services.

3 4 MAKE YOUR WIND TURBINES MORE PROFITABLE The TCM Retrofit & Monitoring Solution gives you the strategy you need including.. Predictive & Prognostic maintenance Optimization of spare part logistics Vibration measurement & Fault Detectability Health indicators & recommended actions Profitability of a wind turbine is measured by: Wind resources Price per kwh Availability O&M costs. You know you have no influence on the first two, but availability and O&M costs can be positively affected by the right monitoring solution and maintenance strategy Five reasons to why you should install the TCM system 1. Make your investment in CMS count by reducing OPEX and O&M costs 2. Predict, prevent & plan: Save time and money with scheduled repairs and avoid failures 3. Stay ahead of your competitors by optimizing your performance and avoid turbine downtime 4. Get complete overview of the conditions of your turbines by health indicators, and receive recommended actions 5. Access Turbine Condition Monitoring (TCM ) knowledge through our TCM Academy training days and user friendly TCM Customer Portal

11 5 6 Future R&D should focus on minimising and, if possible, even elimination of unexpected failures. In other words, the wind industry should move away from corrective maintenance (remedying of failures) and more towards preventive, predictive maintenance (repair just before failure) in order to achieve maximum availability.

Key Benefits Cost effective alternative to In-House monitoring Optimizes daily work for O&M operators Unique opportunity for parallel monitoring Open and transparent customer service Health and fault indicators Lifetime Extension The Gram & Juhl TCM Monitoring Center monitors thousands of wind turbines around the world. With highly qualified diagnosis specialists examining vibration analysis of the wind turbines, you can rest assure that your monitoring is in good hands. With TCM Monitoring, you can quickly and easily identify faulted turbines in a timely manner. Timely alerts of turbine faults is critical for a condition monitoring system, equally important is the ability to get to the critical information that you need efficiently so you can determine what the next steps should be.

7 8 TCM Monitoring features Online Customer Portal Instant access to turbine information 24/7 remote monitoring Online ticket system for customer support E-mail alerts Event reports Health indicators. These are some of the benefits you get with TCM Monitoring. No two companies are the same - therefore we offer 3 different condition monitoring service levels so you can get the flexibility you need. TCM MONITORING BASIC TCM Monitoring Basic is a service for utilities, turbine owners, and service providers.

13 11 12 TCM monitoring reports With the TCM reports you get the information you need and more... TCM Monitoring Assessment report The assesment report is a condition report typically done at the beginning of the monitoring. It is a yearly assessment report providing you with information independent of events and failure detection. It gives you an overview of each turbine and its components. TCM Monitoring EVENT REPORT The event report provides you with graphs and states a health indicator, a description of the detected fault, and recommended actions to be taken. It also includes a time for reaction, letting you know how far you can stretch before taking action, and this way maybe combine the action on one turbine with another turbine, saving repair costs in the process. Clear and severe outer race fault on the main bearing. Trend shows further increase. Exchange of component expected. Recommended Action: Visual inspection of bearing and grease within 14 days Main bearing shows clearly pattern of an advanced outer race fault. Trend has reached severe level. Recommended Action - (040) Urgent inspection at site required; exchange expected in 1 month.

It is an analysis and data mining tool as well as machine modeling tool for TCM. The Ocular platform has a high degree of customization in the user interface, meaning that it can easily be adapted to your needs.

15 19 16 20 Case Story: TCM Monitoring Caught vital Damage In 2016 a Canadian company acquired an old wind farm with Siemens turbines, and was soon to discover the vital effects of the TCM system. Not long into the new acquisition the company s own monitoring specialists caught abnormal vibration measurement on one of the turbines. On the 1st of March 2016, an alarm went off as the TCM system confirmed abnormal vibration measurement that exceeded the TCM criteria rated as critical. What the TCM system caught was a cracked HS pinion tooth, and because the failure was caught in an early stage by the TCM system, it could be repaired and replaced up tower without no collateral damage. On March 30, 2016, an email was send to Gram & Juhl with pictures of the fault and the following statement: I thought you would like to see what our TCM system caught this month - a HS pinion tooth. It s repaired already, up tower replacement, no collateral damage. The company believed it would have led to a catastrophic failure with the gearbox had it not been caught in time by the TCM system. If not caught in time, the HS pinion tooth could have damaged other teeth or in worst case damaged the gearbox, a failure that would have cost the company approx. $420,000. Because the failure was caught in an early stage, it was possible to repair and replace up tower, and exchange the shaft with the pinion, without collateral damage, and with the repair cost of $36,000. The TCM system therefore saved the company a total of $384,000.
