Tkriegers Flak project organisation

Kriegers Flak timeline overview 2016-2021

Kriegers Flak scope of work / packages Vattenfall is responsible for: Procurement Design Manufacturing Installation Commissioning Generation / operation and decommissioning of foundations Inner array grid WTG Conditions of Contract and Employer Requirements The offshore wind farm must have a total capacity of min. 590 MW and max. 610 MW. As the facilities for transmission of power to shore (platform and export cables) are designed for a maximum rated power of 600 MW

Kriegers Flak packages Packages according to BA Wind contract standard: Civil Design (CID) Civil Manufacturing (CIM) Civil Installation (CII) IAC Manufacturing (IAC-M) IAC Installation (IAC-I) WTG Manufacturing (TSA) WTG Service Contract (SAA) WTG Installation Vessel (WIV) Offshore Electrical Works on TP s & substations A & B (OEW) UXO Campaign (UXO) Package without a BA Wind standard process: Site investigation has no standard process and has been defined as part of the already initiated knowledge transfer from e.g. Borssele and HR3

Not included in Kriegers Flak scope of work Vattenfall is not responsible for: Grid connection The transmission grid from shore, including two offshore transformer platforms, to a collection point in the internal grid of the offshore wind turbines, will be financed, established and operated by Energinet.dk. Combined Grid Solution (CGS) New international electricity exchange capacity will be established in connection with the construction of Kriegers Flak. In addition to routing electricity onshore from the Kriegers Flak Offshore Wind Farm, Energinet.dk will build an offshore electricity grid named Combined Grid Solution (CGS) in collaboration with the German system operator, 50Hertz Transmission GmbH.

Hvide Sande Harbour will have a central position in Horns Rev 3 project. Meeting the main contractors Hvide Sande havn får nu manifesteret sin position som Gazellehavn på den jyske vestkyst. Det sker på onsdag den 17. august, når en række af de mest betydningsfulde aktører inden for Offshore Wind mødes i Hvide Sande, for at drøfte perspektiverne og al praktikken i forbindelse med opførelsen af Horns Rev 3. Omdrejningspunktet blandt deltagerne i mødet er Vattenfall og de fire største underleverandører, A2sea, MHI Vestas Offshore Wind, VBMS og GeoSea, som Vattenfall har udpeget til at deltage i opførelsen af Horns Rev 3. Vattenfall ønsker at præsentere projektet og de udvalgte underleverandører for det lokale erhvervsliv i Hvide Sande.

Vattenfall ønsker at præsentere projektet og de udvalgte At netop Hvide Sande er valgt som centrum for mødet glæder direktøren for Hvide Sande Havn og formand for Hvide Sande Service Group, Steen Davidsen: Mødet på onsdag giver os en fantastisk chance for at præsentere, hvad Hvide Sande er i stand til at løfte, når en stor aktør som Vattenfall er med ombord. Denne dialog er med til at smede Vattenfall, Hvide Sande Havn og Hvide Sande Service Group sammen med underleverandørerne i et stærkt samarbejde, der kan skabe vidtrækkende resultater i forbindelse med opførelsen af Horns Rev 3, udtaler Steen Davidsen. Mødet finder sted på onsdag fra kl. 12.30 og byder blandt andet på præsentation af Horns Rev 3 og Vattenfalls O&M-strategi. Aktørerne inviterer også til dialog om, hvordan de ønsker at tilrettelægge samarbejdet med byens erhvervsliv.

Local network an opportunity to create benefit and synergy One point of contact Learn from others e.g. Esbjerg, Grenå and Hvide Sande Stand alone is not an option Invite potential sub suppliers

Focus points Look for good and professional sparring Be able to deliver on time and budget Be aware that your counter part has a professional setup e.g procurement and legal departments EU-rules can be part of the agreement

Use the right people for the right job

A lot of challenges!
