    About the bid

      LanWin4 is one of the offshore grid connection projects being developed by TenneT as part of the 2GW Program. The project is intended to connect large-scale offshore wind generation capacity to the German onshore transmission system. The scope of this project agreement comprises the engineering, procurement, construction, installation and commissioning of a high-voltage direct current (HVDC) grid connection system, including an offshore converter platform and associated converter technology. The project is designed as an integrated EPCI solution to ensure full technical compatibility, system integrity and coordinated delivery of all major components. Due to the high degree of technical interdependency between the offshore platform and the HVDC converter system, the project requires close integration of structural, electrical, mechanical and control system interfaces throughout the design, fabrication, installation and commissioning phases. The successful delivery of the project is of strategic importance for the timely integration of renewable energy sources and the achievement of national and European energy transition objectives.

      Qualification System - 2 GW HVDC Stations (Converter Systems & Platforms) - (previous NX 202008)

      Please note!!!: This publication does not concern a new Qualification System but is a continuation of the Qualification System previously published in Negometrix under number 202008 and the supplement to the Official Journal of the European Union (http://ted.europa.eu) under number 2022/S 125-356696. Negometrix Tender 203753 has been conducted under this Qualification System and has been finished in 2023. Currently no new tender under this Qualification System is foreseen, hence TenneT is not planning to review new requests for qualification under this Qualification System. The scope of this Qualifications System are for the Category Converter (A) and / or the Category Platform (B) Category A Converter: The scope of this category includes in particular: HVDC converter systems for offshore and onshore converter stations and maintenance of the complete HVDC converter stations and optional the civil works for the onshore converter stations. Category B Platform; The scope of this category includes in particular: design, engineering, production, transportation, delivery, project management, installation and commissioning of the offshore platform (topside and jacket) and optional maintenance for the auxillary systems. Under this Qualification System TenneT will issue separate tenders. Each tender for an offshore Grid Connection System will include the full scope of Category A and B. This means there will be no scope split between offshore platform and HVDC. In case of a purely onshore-onshore connection the tender scope will not include the platform (category B).
