TenneT Issues FEED Study Call for 2GW Offshore Platforms

Transmission system operator TenneT TSO BV has issued a contract notice for the provision of a Front End Engineering Design (FEED) study for the Ijmuiden Ver offshore platforms.

This FEED platform study is a part of the development of a 2GW 525 kV DC platform design for the two IJmuiden Ver grid connection systems (GCS) and potentially for other future TenneT projects in the Netherlands and in Germany.

The study focuses on establishing a basic design and acquiring a tender package for the realization of two identical offshore platforms for the IJmuiden Ver project. The development of the High Voltage (HV) components to be incorporated in the offshore platforms will be handled by TenneT, in cooperation with a number of HV system suppliers.

This FEED study covers both the platform structure and the non-high voltage auxiliary equipment packages needed in support of the HV system and inherent platform functions. It also includes the incorporation of the HV system so as to facilitate each and any of the alternative HV designs offered by the individual HV system suppliers. To that end, universal solutions will be designed for each of the interfaces between the HV system and the platform scope.

The study is expected to result in a set of deliverables for the auxiliary systems and platform structure.

Interested parties have until 29 August to respond to this contract notice. The duration of the contract is 18 months.

The 4GW IJmuiden Ver is one of three sites identified by the Dutch Offshore Wind Energy Roadmap 2030. The three sites have a combined capacity of 6.1GW and are expected to help the Netherlands reach the target of 11.5GW of offshore wind capacity by 2030.

The wind farms at the sites are expected to be commissioned between 2024 and 2030.
