Offshore substations

The eye of the needle for feeding into the grid

We are currently reachable by phone to a limited extent. If you have problems calling us, please send an e-mail with your request to or to your contact person.

The substation is the most important structure in an offshore wind farm. This is where all the energy produced by the wind turbines is brought together and converted by transformers to a high voltage transmission of 155kV. This is necessary to ensure that as little energy as possible is lost during transmission over long distances to the next onshore grid node.

If a technical fault occurs on the substation platform then all wind turbines in the offshore wind farm will fail to function. This means that maintenance and repairs services must meet extremely meticulous and high quality standards.

Both in terms of personnel and logistics, Deutsche Windtechnik is in a position to carry out virtually every task needed on the substation platform. Our service portfolio ranges from construction and production monitoring to all other maintenance measures, from a complete data monitoring system to essential testing and expert reports.

The following tasks may be carried out as part of technical management:

  • Technical management of the entire wind farm
  • Storage and analysis of the operating and system data
  • Monitoring and documentation of service and maintenance activities
  • Monitoring of warranty claims
  • Monthly reporting on all data relevant to operations
  • Availability calculations

The range of activities to be employed can be expanded to match demands within the scope of our service portfolio.

For the most part, maintenance includes inspection, maintenance and repair tasks. See below for a brief overview of the range of services we offer:

  • Creation of a maintenance plan
  • Creation of maintenance handbooks and checklists
  • Monitoring and implementation of established maintenance tasks
  • Monitoring and implementation of established maintenance tasks
  • Maintenance of primary transformer and switch gear technology
  • Maintenance of secondary technology (e.g. electricity supply generators, air-conditioning technology, communication engineering, HSE facilities, building services engineering, helicopter deck and lighting equipment)
  • Maintenance of high and medium voltage transmission from offshore substations
  • Necessary and legally-required prevention measures and inspections
  • Supply and replacement of consumable supplies, tools and equipment
  • Provision of work plans to make it possible for the customer to coordinate offshore work and provide the necessary offshore logistics

You can find more information at onshore maintenance.

Our programme of complete data monitoring forms one of the corner stones of our service portfolio. See below for a brief overview:

  • Monitoring 24 hours a day, 365 days a year from our control rooms
  • Incident management (first, second and third level support)
  • Data collection and storage
  • Data analysis and preparation
  • Damage reporting

You can find more information at remote data monitoring.

We provide expert consulting services covering all aspects of our entire service portfolio. This includes:

  • Concept development (maintenance and repair plans, service concepts, emergency power and rescue concepts etc.)
  • Construction and production monitoring
  • Technical inspections and expert reports
  • Creation of work processes, plans and handbooks
  • QHSE management
  • Risk assessments
  • Due diligence

With substations in particular, there are many tasks which all need to be carried in the time shortly before the substation is put into operation. We can provide support during the preparations for commissioning.

  • Planning for commissioning
  • Planning for switching processes
  • Specifying procedures
  • Definition of interfaces
  • Commissioning management
  • Grid connection of medium-voltage power
  • Monitoring of cabling within the wind farm

You can find more information at expertise and consulting.

The cooperation work within Deutsche Windtechnik in combination with ongoing communication with our industry network fosters continuous progress in the state of development.

  • Use of improved control electronics
  • Retrofit development
  • Development of software updates
  • Development of improved electronic components
