Hellenic Cables, the cables segment of Cenergy Holdings, in consortium with Asso.subsea, was awarded a turnkey contract from Réseau de Transport d’ Électricité (RTE) —the sole operator of France’s public electricity transmission network—to supply the cable for the Dunkirk Offshore Wind Farm.

A press release said that Hellenic Cables will design, manufacture and supply 32 km of submarine cables for the double submarine cable link, as well as 38 km of underground cables for the tri-phased double underground cable link, supply submarine and underground cable accessories.  The submarine cables will be manufactured at the company’s plant in Corinth and the land cables at its plant in Thiva, which is currently undergoing a capacity expansion project. The company will also perform on site jointing, testing and termination works and be responsible for the commissioning of the cable links wind farm.

The wind farm, which has a planned capacity between 500 MW and 600 MW, will feature two 225 kV HVAC export cable links which will enable the seamless transfer of clean energy to the French grid. The wind turbines will be spaced around 1 km apart to ensure that the offshore wind farm operates at optimum efficiency.  The project involves complex laying and burial operations in shallow waters.

“This project is an important step forward in supporting France’s renewable energy goals and Hellenic Cables is honored to continue its collaboration with RTE,” said Hellenic Cables General Manager Kostas Savvakis, General Manager. “Our role in the Dunkerque Offshore Wind Farm highlights Hellenic Cables’ commitment to delivering reliable and sustainable energy solutions, while fostering strong collaborations with industry leaders like RTE and Asso.subsea.”

LS Cable & System and LS Marine Solutions have signed a memorandum of understanding (MOU) with British marine engineering company Balmoral Comtec for collaboration on a floating offshore wind power project.

A press release said that Balmoral Comtec is an energy company “with the world’s best technology in building cable protection systems, buoyancy solutions, and submarine infrastructure for the offshore wind power and marine energy industries.”

LS Cable & System notes that it is the first South Korean company to develop a dynamic cable for floating offshore wind power that operates stably even in harsh marine environments. “Under this partnership, we aim to collaborate with Balmoral Comtec to build a safe operation system for floating offshore wind power cables, optimized for extreme marine conditions.”

LS Marine Solutions Co. will support the collaboration by enhancing the installation and operational efficiency of the cables and ensuring stable maintenance. “While the floating offshore wind projects currently account for only about 1% of the market, it is expected to grow rapidly,” the release said. “We will lead the market by driving continuous technology advancements and global cooperation.”

The Lake Tanganyika Submarine Fiber Cable Project, led by BCS Group, has been completed, marking a major milestone in Africa’s digital infrastructure.

Per media reports, the Lake Tanganyika Submarine Fiber Cable Project, led by BCS Group, has been completed, marking a major milestone in Africa’s digital infrastructure. Spanning 400 km and reaching depths of 800 to 1,300 meters, this installation was described as the deepest inland undersea fiber optic cable globally. The project—developed in partnership with major telecom operators, including Airtel—aims to connect Northern and Southeastern Democratic Republic of Congo (DRC) and potentially expand to Tanzania and Burundi.

The BCS Group noted that it has previously had successful submarine installations in Lake Albert (2018-2019) and the Congo River (2022), reinforcing its expertise in challenging underwater fiber deployments. BCS Group currently is operating under licenses in Uganda, Kenya, Rwanda, Zambia, Zimbabwe, Democratic Republic of Congo, Malawi and Angola.

A BCS Group spokesman told WJI that the cable had been supplied by Hengtong, and that it was “95% single armored and 5% double armored cable.” At its website, Hengtong notes that it is the largest optical fiber and power cable manufacturer in China, and one of the world’s top three optical fiber communication enterprises. Also, that it accounts for approximately 25% of the Chinese market share and 15% of the international market share.

 Hellenic Cables has been awarded a U.S. contract for the Silver Run Expansion Project that calls for the addition of new submarine cables adjacent to existing cables currently in service beneath the Delaware River.

A press release said that the project includes the supply of 21 km of single-core, AC high-voltage 230 kV submarine XLPE insulated power cables. The submarine cables will be manufactured at Hellenic Cables’ plant in Corinth, Greece. Manufacturing is set to be completed in the first half of 2026. The cables will form part of a critical power transmission line between New Jersey and Delaware across the Delaware River.

The additional cables will enable the transmission line between the Silver Run substation in Delaware and the Hope Creek substation in New Jersey to accommodate additional electrical flows. New transition structures will be installed at the termination points of the new submarine cable to connect the new cable to the existing overhead transmission line. Equipment at Silver Run substation will also be upgraded as required to serve the additional line capacity.

The project is owned by Silver Run Electric LLC, an affiliate of LS Power, a leading development, investment, and operating company focused on the North American power and energy infrastructure sector, and its wholly owned subsidiary, LS Power Grid, a national electric transmission system developer, owner, and operator.
