Hellenic Cables has won the contract to design, manufacture, transport, and install a package of four 220 kV HVAC export cables to connect the Baltyk II and Baltyk III wind farms in the Polish Baltic Sea to shore.

A press release said that the project—developed by the joint venture of Equinor and Polenergia, Baltyk II and Baltyk III—will each have a capacity of 720 MW and connect to the onshore grid via a total of four HVAC submarine cables with a combined length of 256 km.

Baltyk II and Baltyk III will be two of the first operational offshore wind farms in Poland, supporting the country in its transition to renewable energy. Hellenic Cables is part of a consortium that includes the De Nul Group, which will install them.

“We are proud that Equinor and Polenergia have awarded us to install the export cables for these 2 important Polish projects and their recognition of the combined capabilities of Jan De Nul and Hellenic Cables,” said Wouter Vermeersch, Manager Offshore Cables at Jan De Nul Group.

The companies will execute the connection of the two Baltyk wind farms to shore in 2026. The design and manufacture of the HVAC cables will be performed at Hellenic Cables’ plant in Corinth, Greece.

Hellenic Cables has been awarded a contract from TenneT for the turnkey delivery of approximately 36 km of HVAC offshore grid connection cables for offshore wind farms to be developed in zones (N-3.7 and N-3.8) in Germany.

A press release said that the project, being done in partnership with the Jan De Nul Group, is for the cabling that will connect the wind farms to the DolWin kappa converter station, from where HVDC cables transfer the produced energy to shore. Hellenic Cables will be responsible for designing, manufacturing, supplying, terminating, and testing of three 155kV HVAC grid connection cables and associated accessories.

Manufacturing is planned for 2025 in Hellenic Cables’ submarine cable plant in Corinth, Greece, and delivery is expected in Q3 2025. The Jan De Nul Group will handle the cable transportation, laying and protection works. A single cable will be installed between zone N-3.7 and the DolWin kappa converter, covering a length of 16.5 km. The N-3.8 zone will connect to the converter station by two cables, each about 10 km long.

Hellenic Cables is part of Cenergy Holdings, which itself is a subsidiary of Viohalco SA, a Belgian-based holding company that specializes in manufacturing aluminum, copper, cables, steel and steel pipes.

Hellenic Cables is one of 13 parties from eight countries that are part of a coalition working to further the design and deployment of a 6 MW floating wind prototype in the French Mediterranean.

A press release said that the pan-European project, launched in Paris, seeks to accelerate the roll out of the next generation of floating wind technology for a competitive, more scalable and industrial deployment. Other participants include: X1Wind, Naturgy, 2B Energy, Technical University of Denmark, Hydro, Ecole Centrale de Nantes, Schwartz Hautmont, Ocas, Tersan Shipyard, Ocean Ecostructures and Cybernetix.

Backed by the European Commission under the Horizon Europe program with public funding of €16 million, the project is anticipated to run until 2027. It will lead to the deployment of a 6 MW floating wind prototype to demonstrate at a relevant scale an innovative integrated downwind floating platform design, while advancing in parallel on the industrialization and scaling-up of the integrated solution up to 20MW+ scale, in preparation of commercial floating wind farms under development in Europe.

This project builds upon previous European Projects such as the PivotBuoy which recently led to the installation of a part-scale prototype in the Canary Islands to validate the technology. Design work for the initial 6MW system is currently underway and scheduled to be finalized in 2023. Construction is due in 2023 and 2024, ahead of installation in 2025.

Floating wind is considered one of the lowest carbon electricity generation systems to meet the energy demand in a sustainable way while inducing better competitiveness, less noise and visual pollution, and less interaction with the users of the maritime domain. The NextFloat Project represents a unique opportunity to test a novel and disruptive version of this technology at full scale, driving cost curve reductions in order to deliver industrial-scale projects at the earliest possible stage”.

“After the successful deployment and validation of our innovative low-cost solution in the Canary Islands (PivotBuoy project), the goal now is to scale-up and industrialize the technology in advance of large commercial floating wind projects which will come online at the end of the decade across European, Asian and U.S. waters,” said X1 Wind Founder and CEO Alex Raventos. “Wind will allow us time to drive substantial improvements in the competitiveness of floating wind as we prepare for long-term mass deployment.”

Alcoa Corporation announced that it is supplying low-carbon EcoLum™ aluminum to Hellenic Cables S.A., one of the largest cable producers in Europe with key markets in renewable energy transmission and distribution.

Alexis Alexiou, CEO of Cenergy Holdings and Hellenic Cables, said that Hellenic Cables finds strong alignment with Alcoa’s strategic priority to advance sustainably. “We prioritize the urgency of deep and immediate mitigation actions, hence EcoLum minimizes our environmental impacts and enhances the value of our products.”

7/3/2022 - 

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.
