Ask us if your wind turbine is not listed here. We are positive that we will find a solution for you.
This depends on your system, and the services you commission us with. An oil change usually takes around two to three hours for a standard wind farm model such as a V80, MD70, MD77, or GE1.5. Our advanced technology, specially trained staff and many years of experience will, of course, save you valuable time compared to a manual oil change.
We will usually not charge you for travel costs to and from your wind turbine as we aim to work efficiently and combine as many oil changes at as many different customers as possible in one tour. We will usually deliver the service four to eight weeks after you place the order. Call us and arrange a fixed date with us if you require our services sooner; we will then charge you for travel costs.
We will not require your service staff to be present in order to perform common gearbox and hydraulic oil changes as long as we have access to your wind turbine. We will inform you before submitting an offer if we might be needing your service staff for more unusual wind turbines or services.
We always provide a complete package of services, logistics and oil filter elements, so we cannot guarantee our oil service for oil products not provided by us. And: from our experience, a complete package costs less than the additional costs of provisioning by customers due to additional cost factors such as handling and shipping.
No. We operate as an independent service provider, and need to take the gearbox manufacturer's official specifications and approved materials into account for each wind turbine.
Please refer to the corresponding maintenance and service contract with your equipment manufacturer, as these usually include the exact change intervals required. It is especially important to make sure that the maintenance intervals are actually kept to as specified. For an oil change according to analysis, you will need to check whether the oil is still in good working condition, or whether it is impaired due to deposits in the gearbox; this will be difficult or impossible to solve in the long term. We at C&D also provide our expertise and qualified specialists for the purpose.
