DolWin3 Platform Equipped with 2 Power Transformers

Alstom and Nordic Yards have installed two 700 MVA power transformers on the DolWin3 converter platform based in the Warnemüde shipyard in Germany, operated by Nordic Yards.

The transformers were designed and built by Alstom specifically for the DolWin3 converter project at its Mönchengladbach plant in Germany. During routine inspections, one transformer can continue to operate allowing the converter platform to transmit the energy generated uninterrupted.

“The 900 MW wind energy DolWin 3 is the most powerful and largest HVDC-converter platform built at Nordic Yards. In cooperation with Alstom and TenneT we are moving the German energy transition another step further,” said Herbert Aly, CEO of Nordic Yards.

“The two power transformers are core components of the DolWin 3 offshore converter platform. Today’s milestone further confirms our leadership in HVDC technology. This installation is the prerequisite for completion of the platform’s steel structure by Nordic Yards and the onward completion of the project,” said Gerhard Seyrling, Vice President Alstom Grid, Region Central & Eastern Europe and Russia.

In 2013, TenneT awarded DolWin3 contract to Alstom, to supply and construct both the onshore and offshore converter stations as well as the connecting cable systems for DolWin3. Alstom then contracted Nordic Yards to build and install the offshore converter platform.

The project is expected to be completed by 2017.
