Project IJmuiden Ver
IJmuiden Ver is the first offshore wind HVDC grid connection system project of TenneT TSO B.V. in the Netherlands. The goal of the project is to connect 4 GW of offshore wind power generated in the North Sea. The connection system will be realized as two HVDC configurations each rated at 2 GW with a nominal voltage of ±525 kV. The first link will be operational in 2027.
FEED platform study
This FEED (Front End Engineering Design) study is part of the preparatory work for the development of thesegrid connection systems (GCS). It focusses on establishing a basic design and tender package for the realisation of two identical offshore platforms as part of these GCSs. The development of the High Voltage (HV) components to be incorporated in the offshore platforms will be by TenneT, in cooperation with a number of HV system suppliers.
The FEED study covers both the platform structure and the auxiliary equipment packages needed in support of the HV system and inherent platform functions. It also covers the incorporation of the HV system, and target at being able 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 development of the individual HV systems design and specification and the development of the platform basic design and specification will have to run in concert so as to ensure timely exchange of information and interface resolution.
The goals of the FEED are amongst others: - to develop a Basic Design "Plus" (i.e with technical specifications down to main component level) for the platform structure and the auxiliary systems
- to provide this Basic Design "Plus" as a basis for the platform realization Tender, therewith reducing the level of uncertainty and risk for the Tender participants, and thus minimise the associated price inflation
- to create clarity on all the interfaces between the platform and other parts of the grid connection system, and thus reduce the risk for all parties involved
- to ensure the platform and auxiliary system design covers and includes all TenneTs O&M requirements and lessons learned on its previous projects and during its ongoing operations
- to pursue TenneTs goal of standardization in its platform designs and operational philosophies
- to create a platform design that can facilitate HVDC system and component designs from multiple suppliers
- to provide further detail and substantiation for TenneTs investment cost assessments
Even though this FEED study is contracted separately from the HV system design, TenneT is still to decide on its strategy for tendering the realization. This can be either an EPC approach for the complete platform including the HV equipment and T&I, or in separate packages with a split between the platform including auxiliary systems and the HV package. This decision will be made in the course of 2020.
