DEME Offshore has been awarded a contract for the transport and installation of the jackets and topsides for two Hollandse Kust offshore substations. The company will also supply and install scour protection for both substations.

The contract has been awarded by the joint venture ENGIE Solutions-Iemants (a subsidiary of Smulders), which is responsible for the engineering, procurement, construction and offshore installation of the two substations, which will be installed at the Hollandse Kust (noord) and (west Alpha) wind farms.

Installation of the scour protection and jacket for Hollandse Kust (noord) is planned for the second half of 2021, while the topside for Hollandse Kust (noord) and jacket for (west Alpha) will be installed during the summer of 2022. The topside for Hollandse Kust (west Alpha) will be installed in 2023.

The offshore substations will be located in the Dutch North Sea. Forty per cent of the Netherlands’ electricity needs will come from offshore wind farms by 2030. TenneT will realise the grid connections for these wind farms. For DEME, a “contract” refers to a contract with a value of less than EUR 50 million.

Project Hollandse Kust

The offshore platforms Hollandse Kust (noord) and Hollandse Kust (west Alpha) platforms will be located in the North Sea along the Dutch coast and will be operational by respectively 2023 and 2024.

In 2030, 40 percent of the electricity demand of the Netherlands will be supplied by the electricity of offshore wind farms. TenneT realises the grid connections for these wind farms. These 700 MW platforms will be the fifth and sixth large-scale grid connections for offshore wind energy in the Netherlands, built and operated by TenneT.

The first high-voltage connections for the wind farms near Borssele are now operational, and will be followed by the connections for Hollandse Kust (zuid) in 2022. TenneT will realise approximately 9.6 GW of high-voltage connections in the Dutch North Sea by 2030.
