Additional information

EnBW and CWind jointly implemented the first satellite communication system in remote management of temporary power supply in the offshore wind industry at EnBW Baltic 2. The system is proving a resilient and effective means of supporting offshore construction during this winter period in the Baltic Sea.

Knowing that mobile network based communication would not cover its farshore wind farm located 40km off the island of Ruegen, EnBW was looking for an innovative solution, in order to monitor and control the provision of temporary power during construction.

Garvin Bracker, Manager Offshore Construction Project Services Offshore at ENBW, explains: “We knew that satellite based communication has long been used in offshore oil & gas and the maritime sector but nobody had tried it yet in this context in offshore wind. We believed it could provide substantial benefits and when we tendered for the temporary power supply we asked for proposals to include innovative satellite telemetry.”

CWind supplied generators equipped with a remote control and monitoring board as well as a satellite communication modem. The modems, supplied by CPN Satellite Services in Germany, coupled with CWind’s IT Development Team providing the infrastructure required, allow CWind to transfer all data from the remote board to its databases onshore for monitoring, reporting and management. The two-way communication via the satellite also enables CWind to start and stop machinery in field to proactively manage power supply even during prolonged bad weather periods.

How well did we do?

Stefan Wallenmaier, Project Manager Offshore Wind EnBW, commented on the contract award: “The decision to move to a single supplier for all elements of the temporary power supply, and the choice of that partner, was a crucial decision for us. CWind convinced us fully that they were able to meet the very considerable technical and logistical challenges of handling the provision of temporary power for our 80 turbines, 32km off the coast of Rugen Island. A constant, efficient and safe power supply is critical to the smooth and uninterrupted construction of the wind farm, in an at times rough environment.”

Bernd Sahling, Senior Procurement Manager, RWE Innogy, remarked on the contract award: “We carefully considered our options for the temporary power supply at NordSee Ost. The offer from EP Tools and CWind convinced us both in terms of the costs and in terms of the quality of equipment and service.”
