TenneT is set to start construction this week on the onshore converter substation for the 900MW Borwin 3 offshore wind farm in Emden/Ost in the German state of Lower Saxony.

A transformer will be brought to the site by the end of next year, while commissioning of the converter station is slated for late summer 2017.

Work started in March on burying a 30km DC onshore cable from Hamswehrum near Emden to the planned onshore substation in Emden/Ost.

Groundwork will take place along the 30km cable oute and last until the early summer of 2016. The cable will be buried in sections of 1150 metres and be connected via sockets.

The first parts of the offshore cable were buried in September.

Drydocks World started steel cutting in late September in Dubai for the offshore platform Borwin gamma, on behalf of the consortium of Siemens and Petrofac.

TenneT awarded the contract last year to Siemens to supply HVDC transmission technology for the grid link together with Petrofac, which is handling construction and installation of the offshore platform.

Borwin 3 is slated to be fully commissioned in the third quarter of 2019.
