Keppel-Aibel consortium wins contract for German converter stations

A consortium comprising Keppel Offshore & Marine’s wholly-owned subsidiary Keppel FELS and Aibel AS has clinched a contract to develop offshore and onshore converter stations in Germany.

The contract is awarded by TenneT Offshore, a grid operator in the Netherlands and Germany.

Together with its subcontractor ABB (ASEA Brown Boveri), the consortium will design, engineer, procure, construct, install and commission a 900MW offshore HVDC (High Voltage Direct Current) converter station and an onshore converter station.

The offshore converter station based on Aibel’s patented design will be equipped with living quarters, a helideck and lifting cranes.

Scheduled to be completed in 2024, the offshore and onshore converter stations will be part of the DolWin cluster servicing offshore wind farms in the German sector of the North Sea. The offshore converter station will be located approximately 130km from the onshore converter station and they will provide grid connection for the offshore wind power plants to supply electricity to around one million households in Germany.


Keppel FELS’ share of the converter stations contract is worth about SGD560m ($411m).

“This is Keppel O&M’s first major project of this scale and extends our track record in supporting the renewable energy industry,” said Chris Ong, ceo of Keppel O&M.

Keppel had previously completed a mobile application barge for an offshore substation in Germany as well as an offshore wind turbine installer.

“We see opportunities in this segment as the offshore renewables market is expected to increase significantly over time with increasing concerns over climate change. Keppel O&M is able to leverage our expertise in offshore energy infrastructure to offer customised and high quality solutions across the offshore wind farm value chain,” Ong said.

According to Bloomberg New Energy Finance, annual installed capacity in the offshore wind sector is projected to increase from 4.5GW in 2018 to 12GW in 2030, resulting in a total cumulative capacity of 115GW in 2030.
