It provides clean, competitive and reliable energy while creating local and international value in terms of jobs and economic growth. This is now a critical moment: Member States have the possibility to take a big step forward in decarbon- ising the energy sector and increase security of supply. But to exploit these benefits, actions must be taken fast. This document provides an overview of benefits and ac- tions needed to exploit the full potential of offshore wind in the Baltic Sea. 1.

  • Kriegers Flak, Denmark
    Offshore Wind Farm Monitoring Kriegers Flak, Denmark Kriegers Flak is Denmark’s largest offshore wind farm with a production capacity of just over 600 MW. The transmission network operators required a reliable, high-performance solution for protecting and monitoring cable loads and immediately detecting cable faults. AP Sensing is monitoring a total of 300 km of this asset, using 6 Distributed Temperature Sensing (DTS) units and 9 Distributed Acoustic Sensing (DAS) units. The new Kriegers Flak wind farm is located off the Danish coast in the Baltic Sea and will be used to exchange power in a combined grid solution between Denmark and Germany, a project that is unprecedented worldwide. Kriegers Flak offshore wind farm ©Energinet AP Sensing was selected by Danish transmission operator Energinet to monitor its networks; our solution enables the Danish and German network operators to protect and optimize their network performance. Our equipment is in use on the two offshore platforms of Kriegers Flak (A and B), as well as on the onshore substations Bjaeverskov and Ishoj. For the 300 km that we are monitoring, 6 DTS units with a range of 30-50 km and 1-4 channels are in use for thermal profiling and to detect thermal abnormalities. Additionally, our monitoring solution for Kriegers Flak utilizes 9 DAS units with ranges from 25-50 km and 1 channel each for fault location. In total, AP Sensing is monitoring: • the two 220kV export cables from the offshore platforms to Bjaeverskov, • the 220kV interlink cable between the offshore platforms Kriegers Flak A and B, • the two 150kV interlink cables between the offshore platforms Kriegers Flak B and the German Baltic 2, • a 220kV onshore cable between Bjaeverskov and Ishoj, • a 400kV onshore cable between Ishoj and Hovegard, and • two 130kV interconnection cables in the Oresund between the onshore substation Teglstrupgard in Denmark and the onshore substation Larod in Sweden.

  • Seminar on Cooperation on the EIA Convention
    1 Swedish Ministry of Sustainable Development Cooperation on the EIA Convention in the Baltic Sea subregion Report of a Seminar in Stockholm 20-21 October 2005 The Seminar The work plan for the implementation of the Convention on Environmental Impact Assessment in a Transboundary Context (EIA Convention) for the period up to the fourth meeting of the Parties was adopted at the Third Meeting of the Parties 2004. Subregional cooperation to strengthen contacts between the Parties is an activity in the work plan and the overall objective is improved and developed application of the Convention in the subregions. Denmark, Estonia, Finland and Sweden made a commitment at the Meeting of the Parties to perform this activity for the Baltic Sea in 2005. Within the framework of this activity Sweden on behalf of the other lead countries arranged a Seminar on Cooperation on the EIA Convention in the Baltic Sea subregion on 20 – 21 October 2005 in Stockholm for the Focal Points and Points of Contact of the Convention from the states bordering the Baltic Sea. The Seminar was held at the Swedish Environmental protection Agency and the twenty participants represented all the nine states around the Baltic Sea (Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russian Federation, Sweden), the Secretariat of the EIA Convention, HELCOM and the NGO Eco Terra. A list of the participants is found in the end of this report. The seminar consisted of two short lectures on the state of the Convention and on the state of the Baltic Sea, an overview of Espoo activities in the subregion, presentations of the practical application of a number of Espoo cases in several states, discussions on cooperation with other conventions and organisations in the subregion and on the Protocol on Strategic Environmental Assessment and finally group discussions on conclusions and further work.

Following the successful organisation of the 3rd International Stability Workshop on "Contemporary problems of ship stability and operational safety" in 1997 in Crete, a number of prominent colleagues dealing with maritime R&D in Europe and overseas asked NTUA to consider hosting again a series of conferences and meeting events at the beautiful island of Crete. The response was, of course, positive despite of the anticipation of organisational problems related to the uniqueness of this multi- conference. I am very pleased to see you all here, especially those of you who have come from overseas. We are expecting over the next few days close to 200 colleagues and friends from all over Europe, USA and Japan, a clear indication of high expectations and of interesting days ahead. We count among the participants not only internationally recognised experts but also more than 20 young researchers of European academic and industrial institutions thanks to the support of the TMR programme of the European Commission.
