Hellenic Cables has been awarded an Exclusivity and Capacity Agreement (ECA) to supply 66 kV XLPE-insulated inter-array cables and associated accessories for the Hai Long 2 and 3 offshore wind projects.

A press release said that the Hai Long offshore wind farm project in Taiwan will include two offshore wind farms—Hai Long 2 (HL2) and Hai Long 3 (HL3)—that will have a total installed capacity of 1,044 MW. The overall project is one of Taiwan’s largest offshore wind farms. It is jointly developed by Northland Power Inc., Yushan Energy Pte Ltd and Mitsui & Co.

The project will be located 40-50 km off the Changhua coast, at a water depth of 35-55 m. HL2 itself is split between two sub-wind farms: HL2A, with a maximum installed capacity of 300 MW, and HL2B, with a maximum installed capacity of 232 MW. HL3 has a maximum installed capacity of 512 MW.

Under the ECA, Hellenic Cables will supply approximately 140 km of 66 kV XLPE-insulated inter-array cables and associated accessories. They will be made at the company’s plant in Corinth, Greece. The manufacturing is expected to be completed in Q1 of 2024 for Hai Long 2 and in Q4 of the same year for Hai Long 3.

“We are delighted to have secured Hellenic Cables as our cable manufacturer and to be establishing this cooperation,” said Hai Long Offshore Wind Project Director Felipe Montero. “Hellenic Cables is taking a critical scope in our project, and we’re pleased to have this scope taken care of by a market leader in submarine cables manufacturing, such as Hellenic Cables.”

4/3/2022 - Hellenic Cables, a business of Cenergy Holdings, was recently awarded a turn-key project from HEDNO—a regulated entity that is the sole active distributor of electricity throughout Greece—to supply some 19 km of submarine cable to interconnect several new interconnections.

A press release said that the contract also calls for the supply and installation of accessories, as well as “the implementation of all relevant works” for the connection of the submarine cables to HEDNO’s land network. The contract was signed by HEDNO and Fulgor, which is a 100% subsidiary of Hellenic Cables.

Cable production and installation is expected to be completed by May 2023. All cables will be manufactured at the Hellenic Cables plant in Corinth, Greece.

“We are happy to support HEDNO’s development program for the modernization of Distribution Grids in order to ensure uninterrupted and reliable supply to the country’s islands and we thank them for trusting us again,” said Alexis Alexiou, CEO of Cenergy Holdings and Hellenic Cables.

3/4/2022 – Greece’s Hellenic Cables recently reported two contracts, both related to Dogger Bank (A, B and C), the world’s largest offshore wind project, which is located in the North Sea, between 125 and 290 km off the east coast of Yorkshire.

Per Wikipedia, since 2017, Dogger Bank Wind Farm Ltd. has developed what is known as Dogger Bank A, B and C, while a fourth wind farm has been developed by Sofia Offshore Wind Farm Ltd. as Sofia Offshore Wind Farm.

A press release said that Hellenic Cables has been awarded the Dogger Bank C array cable contract by DEME Offshore, the renewables business unit of DEME Group. Already the designated supplier for Dogger Bank A and B, with this contract Hellenic Cables becomes the sole inter array cables’ supplier for the massive project.

Under the new contract, Hellenic Cables will supply some 240 km of 66 kV XLPE-insulated inter-array cables and associated accessories. This is in addition to 650 km of array cables already awarded for phases A & B. The cables will be produced at the company’s plant in Corinth, Greece. Production of the cables for Dogger Bank C is set to begin in 2023 and delivery will be a phased roll out in line with the project execution program.

“We’re proud to be the exclusive array cables supplier for the world’s largest offshore wind farm, which provides the U.K.’s largest single source of renewable energy,” said Alexis Alexiou, CEO of Cenergy Holdings and Hellenic Cables.

The second project, for the Sofia Offshore Wind Farm, is for RWE, a German energy firm that contracted Van Oord Offshore Wind UK to provide the engineering. The project calls for Hellenic Cables to supply some 360 km of 66 kV inter-array cables and accessories to the Sofia offshore wind farm. The company will also make the cables at its Corinth plant. Cable production is set to begin in 2022 and be completed in 2023. The cables will be installed by Van Oord’s cable-laying vessel, Nexus.

The 1.4 GW Sofia offshore wind farm is located 195 km from the nearest point on the U.K.’s North East coast on a site of 593 sq km. “Building on the expertise and know-how demonstrated in previous projects, such as the Hollandse Kust (South) project, our goal is to successfully implement this project as well. Together with our investment in the next-generation custom-built green cable-laying vessel Calypso, this highlights Van Oord’s drive to continuously reinforce its market position,” said Arnoud Kuis, managing director at Van Oord offshore wind.

The Dogger Bank is an attractive location for offshore wind farms because it is far away from shore, avoiding complaints about the sight of wind turbines, yet at a water depth shallow enough for traditional fixed foundation wind turbine designs to be deployed. Fixed-foundation wind turbines are economically limited to maximum water depths of 40 to 50 meters, whereas greater water depths require new floating wind turbine designs that cost significantly more to build. All four farms have a delivery date between 2023 and 2025.

Hellenic Cables, a Greek supplier of submarine cable systems, has won a contract from Seaway 7, Subsea 7’s Renewable Energy business unit, to supply 66 kV inter-array cables and components for an offshore wind farm.

A press release said that the order is for the Seagreen Marine Wind Farm, is a 1.075 GW project located 27 km off the coast of Angus, Scotland, where it will be developed and operated by Seagreen Wind Energy Limited. When completed, it will be the largest wind farm in Scotland.

The contract calls for Hellenic Cables to design and produce approximately 320 km of 66 kV inter-array cables with XLPE insulation, as well as relevant components. The cables will be made in the company’s submarine cable production unit in Corinth. Delivery is set for early 2022.

“We are proud to support Seaway 7 in a project that will provide low carbon energy to around 1 million households and accelerate the energy transition in the U.K.,” said Hellenic Cables CEO Alexios Alexiou. Hellenic Cables is one of the largest producers of cables in Europe, manufacturing power and telecommunication cables as well as submarine cables for various industrial uses, such as submarine cables for wind power projects and interconnections, as well as turnkey power transmission and distribution projects.

In other news, earlier this year Hellenic Cables announced that it has reached an agreement with Enel Green Power that will allow all its electricity needs in Greece to be met by renewable energy sources. That would include its submarine cable factory in Corinth and its high-voltage cable factory in Thebes.

Hellenic Cables announced that it will be a supplier for two projects, one for Denmark and the other for the U.S.

A press release said that Energinet, an electricity transmission company owned by the state of Denmark, has selected Hellenic Cables as one of the three cable manufacturers in the framework agreement for underground high voltage cable systems (145-170 kV). In addition to supplying H-V cables, the contract includes all the other elements needed for Denmark’s high-voltage onshore network. The eight-year contract (2020-2028) will require an estimated 4,200 km of cable during the cited timeframe. The cable orders will be distributed to the three manufacturers either by direct assignment or by competitions between participating manufacturers per the Framework Agreement. Hellenic Cables will make the 145-170 kV cables at its plant in Thebes.

Hellenic Cables also reported that, in the U.S., it has an agreement with Semco Maritime A/S to supply inter-array cables for the Mayflower Wind project, a joint venture of Shell New Energies US LLC and EDPR Offshore North America LLC. The offshore wind project is expected to start-up in 2025. The company will provide some 300 km of 66 kV, XLPE insulated submarine inter-array cables that will connecting the project’s wind turbines to its offshore substation. The cables will be manufactured at Hellenic Cables’ submarine cable production facility in Corinth, Greece. The order is expected to be completed by the end of 2023, with final installation expected around 2025.

Cablel® Hellenic Cables announced that it has been awarded part of an R&D tender for a Floating Wind Joint Industry Project (Floating Wind) focused on the development of high-voltage dynamic export cables for the transmission of power from floating wind farms to shore

A press release said that the project, under the auspices of Carbon Trust, is a collaborative initiative between industry partners EnBW, ENGIE, Eolfi, E.ON, Equinor, innogy, Kyuden Mirai Energy, Ørsted, ScottishPower Renewables, Shell, Vattenfall and Wpd, with support from the Scottish government. The goal is to develop commercial-scale floating wind farms, with this R&D effort representing a new technology that is a critical factor for the commercial deployment of floating wind technology.

“For this purpose, Hellenic Cables will support the design, initial testing and development of dynamic cables ranging from 130kV to 250kV to enable the efficient transmission of power from floating wind turbines to shore,” the release said. The award for the company is for the first phase of the project, due for completion in March 2020.

The cables will be made at the plant of Fulgor SA, a subsidiary of Hellenic Cables, at its plant in Soussaki, Corinth, Greece, where Fulgor is capable of making some of the world’s longest submarine cables in continuous lengths. Cablel Hellenic Cables, which is part of Belgium’s Cenergy Holdings SA, manufactures power and telecom cables as well as submarine cables. It has four plants in Greece and one in Bulgaria.

Last November, Cablel Hellenic Cables won a contract worth some 29 million euros and Fulgor a contract worth some 18 million euros to provide and install submarine and land cables in the Rio-Antirrio area for the extension of the 400kV grid towards Peloponnese, Greece. Those projects called for 18 km of six 400kV single-core submarine cables and optical fiber submarine cables, and some 42 km of 400 kV land cables for the route from the landing points of the submarine cables in Peloponnese and Central Greece.
