HVDC HelWin1
HVDC HelWin1 is a high voltage direct current (HVDC) link built to transmit Offshore wind power to the power grid of the German mainland. The project differs from most HVDC systems in that one of the two converter stations is built on a platform in the sea. Voltage-Sourced Converters are used and the total cable length is 130 km. The project was completed and handed over to its owner, TenneT, in February 2015. Context HelWin1 is part of an ambitious programme of providing grid connections to offshore wind parks off the coast of Germany, in the German Bight, as part of the German Energiewende (Energy Transition) programme. HelWin1 forms part of the ''HelWin cluster'', named after the German island of Heligoland. HelWin1 has been built to transport power from the Nordsee Ost and Meerwind Süd/Ost wind parks. HVDC has been chosen for most of the grid connections because the relatively long distance involved – both from the wind park to shore and from the shore to ...

Heligoland
Heligoland (; german: Helgoland, ; Heligolandic Frisian: , , Mooring Frisian: , da, Helgoland) is a small archipelago in the North Sea. A part of the German state of Schleswig-Holstein since 1890, the islands were historically possessions of Denmark, then became the possessions of the United Kingdom from 1807 to 1890, and briefly managed as a war prize from 1945 to 1952. The islands are located in the Heligoland Bight (part of the German Bight) in the southeastern corner of the North Sea and had a population of 1,127 at the end of 2016. They are the only German islands not in the vicinity of the mainland. They lie approximately by sea from Cuxhaven at the mouth of the River Elbe. During a visit to the islands, August Heinrich Hoffmann von Fallersleben wrote the lyrics to "", which became the national anthem of Germany. In addition to German, the local population, who are ethnic Frisians, speak the Heligolandic dialect of the North Frisian language called . Name Th ...

International Council On Large Electric Systems
The International Council on Large Electric Systems (CIGRE) is a global nonprofit organisation in the field of high voltage electricity. It was founded in Paris, France in 1921. The scope of its activities include the technical and economical aspects of the electrical grid, as well as the environmental and regulatory aspects. More specifically, the objectives of CIGRE are to: *facilitate technical exchanges among those involved in the production, transmission, and distribution of electrical energy; *communicate the state of the art and the technical knowledge in these fields; *inform the decision makers and regulators in the field of high voltage electricity by means of publication in its magazine ''Electra'' or through the organisation of biennial conferences, named ''Sessions'', that take place in even years in Paris, France. CIGRE membership is open to individuals, companies and organisations involved with any aspect of high voltage engineering. Member organisations and c ...

HVDC DolWin3
HVDC DolWin3 is a high voltage direct current (HVDC) link to transmit Offshore wind power to the power grid of the German mainland. The project differs from most HVDC systems in that one of the two converter stations is built on a platform in the sea. Voltage-Sourced Converters with DC ratings of 900 MW, ±320 kV are used and the total cable length is 160 km. The overall project is being built by Alstom with the cables supplied by Prysmian and offshore platform by Nordic Yards.

HVDC DolWin2
HVDC DolWin2 is a high voltage direct current (HVDC) link to transmit offshore wind power to the power grid of the German mainland. The project differs from most HVDC systems in that one of the two converter stations is built on a platform in the sea. Voltage-Sourced Converters with DC ratings of 900 MW, ±320 kV are used and the total cable length is 135 km. The project is similar to the HVDC DolWin1 project but has a slightly higher power rating and uses a different design of offshore platform. The platform was designed by Norwegian company Aibel and built by Drydocks World in Dubai and transported to Europe in the summer of 2014 to be fitted out at the Aibel yard in Haugesund in Norway. The platform, which is of a floating, self-installing design not previously used in an HVDC project, sailed out from Haugesund on 1 August 2015 and was installed in the North Sea ten days later.

HVDC BorWin1
HVDC BorWin1 is the first HVDC facility in the world to be built for importing power from an offshore wind Offshore wind power or offshore wind energy is the generation of electricity through wind farms in bodies of water, usually at sea. There are higher wind speeds offshore than on land, so offshore farms generate more electricity per amount of c ... park to shore, and the first to use voltage source converters (VSC) in Germany. It connects the offshore wind park BARD Offshore 1 and other offshore wind farms in Germany near Borkum to the European power grid. The facility was built by ABB Group, ABB and has a capacity of 400 MW at a bipolar voltage of ±150 kV. HVDC BorWin1, which leads from BorWin Alpha Offshore Platform to Diele substation, consists of a of underground and of submarine cable. Unlike the later (and more powerful) HVDC connections that have been built for transmitting wind power to shore in Germany, Borwin 1 uses cascaded HVDC converter#Tw ...

Cross-linked Polyethylene
Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links. It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats. It is also used for natural gas and offshore oil applications, chemical transportation, and transportation of sewage and slurries. PEX is an alternative to polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC) or copper tubing for use as residential water pipes. Properties Low-temperature impact strength, abrasion resistance and environmental stress cracking resistance can be increased significantly by crosslinking, whereas hardness and rigidity are somewhat reduced. Compared to thermoplastic polyethylene, PEX does not melt (analogous to elastomers) and is thermally resistant (over longer periods of up to 120 °C, for short periods without el ...

Büsum
Büsum () is a fishing and tourist town in the district of Dithmarschen, in Schleswig-Holstein, Germany. It is situated on the North Sea coast, approx. 18 km southwest of Heide. Büsum is also the administrative seat of the ''Amt'' ("collective municipality") Büsum-Wesselburen. History and geography The first documented mention of Büsum (as an island) dates from the year 1140. The island's name on medieval documents changed several times from the original Bivsne (1140) to Busin (1208), Busen (1281), and Buzen (1447). Büsum's medieval history has been documented through the chronicles of Neocorus (Johannes Adolph Köster), a pastor and teacher in Büsum during the 16th century. Geographical history During medieval times, Büsum was an island with three villages, Süderdorp, Middeldorp and Norddorp. Devastating floods in 1362 (Grote Mandrenke), 1436, and 1570 ( All Saint's Flood) drowned most of the island and destroyed the two settlements Süderdorp and Middeldorp. The ...

Warnemünde
(, literally ''Mouth of the Warnow'') is a seaside resort and a district of the city of Rostock in Mecklenburg, Germany. It is located on the Baltic Sea and, as the name implies, at the estuary of the river Warnow. is one of the world's busiest cruise ports. History Founded in about 1200, was for centuries a small fishing village with minor importance for the economic and cultural development of the region. In 1323 lost its autonomous status as it was purchased by the city of Rostock in order to safeguard the city's access to the Baltic Sea. It was not until the 19th century that began to develop into an important seaside resort. Today has approximately 8,400 inhabitants. Economy Once completely dependent on the fishing industry, 's economic alignment has shifted inevitably from the primary to the secondary and tertiary sector. Besides the Nordic Yards Warnemünde ship yard (the former ), the economy largely depends on tourism. The construction of a modern cruise l ...
