  • Metocean Data Requirements
    Document title 1 Metocean Data Requirements Document title 2 The European Union is a unique economic and political partnership between 28 European countries. In 1957, the signature of the Treaties of Rome marked the will of the six founding countries to create a common economic space. Since then, first the Community and then the European Union has continued to enlarge and welcome new countries as members. The Union has developed into a huge single market with the euro as its common currency. What began as a purely economic union has evolved into an organisation spanning all areas, from development aid to environmental policy. Thanks to the abolition of border controls between EU countries, it is now possible for people to travel freely within most of the EU. It has also become much easier to live and work in another EU country. The five main institutions of the European Union are the European Parliament, the Council of Ministers, the European Commission, the Court of Justice and the Court of Auditors. The European Union is a major player in international cooperation and development aid. It is also the world’s largest humanitarian aid donor. The primary aim of the EU’s own development policy, agreed in November 2000, is the eradication of poverty. The European Commission is the European Community’s executive body. Led by 27 Commissioners, the European Commission initiates proposals of legislation and acts as guardian of the Treaties. The Commission is also a manager and executor of common policies and of international trade relationships. It is responsible for the management of European Union external assistance.

They are intended to guide the dialogue, but you are of course welcome to not answer them, and to ask any questions of you own. 2 METOCEAN – OVERALL STRATEGY Two Main options will be presented in the following slides: 1. Default Scope (default option) Ø Energinet will provide metocean data and -documentation which is sufficient for the bidders to submit a qualified econoMic bid. Ø This Material shall have uncertainties so sMall that they only have a Minor effect on the bid. FurtherMore, it shall be so extensive that it, for this purpose, either directly provides the bidders with the necessary MetOcean paraMeters, or allow the bidders and their advisors to calculate these paraMeters theMselves. Ø This Material shall be as detailed, and of a quality at least as good, as what is used elsewhere in Northern European offshore wind projects for this purpose. Ø No certification of the Material; only plausibility stateMents from an independent (possibly DS/EN 61400-22 accredited) third party. 2. Comprehensive Scope (only provided if bidders present convincing arguMents for it) Ø In addition to the Default Scope: • The Material provided will either directly state, or be applicable as a basis to calculate, Site Conditions AssessMent (SCA) parameters for MetOcean topics according to the SCA Module of DS/EN 61400-22, and, by reference, IEC 61400-3-1 (2019).
