8/3/21 Nexans, which notes that it has been a long-term partner in renewable energy developments, announced that it has been awarded a contract by Equinor to supply power export cable for its innovative floating solar pilot offshore Frøya in Norway.
A press release said that the pilot project, called Frøya, is scheduled to come online this December, at which time it will be the world’s first floating solar plant operating in rough offshore waters. The Frøya floating plant will measure 80 m x 80 m, with a height of less than 3 m above the sea surface, hosting an array of solar panels capable of producing up to 1 megawatt.
Nexans will supply 5 km of 22 kW export cable to connect the floating platform from shallow waters to land. The most challenging aspect for the cable construction is to handle the dynamic loadings as the connection at the platform end pitches up and down with the waves. Nexans is utilizing a three-core cable design of a type well proven in offshore wind farm and fish farming installations. The cable will be manufactured at Rognan plant in Norway.
“Our mission for Nexans is to electrify the world,” said Krister Granlie, vice president of the submarine telecom and special cables business unit of Nexans. “Our mission for Nexans is to electrify the world. That means exploring every possible opportunity to help develop new sources of green energy. So, we are delighted to be working once again with Equinor on a truly exciting project that further extends the boundaries of what might be possible in generating renewable energy offshore.”
Utility-scale floating solar power is currently one of the fastest growing renewable technologies as governments and investors around the world explore every possibility for safer, sustainable and decarbonized energy. This is expected to drive almost 10 gigawatt of new floating solar deployment by 2025.
NKT announced that the company has won a project to install 200 km of 80 kV high-voltage DC offshore power cables for the second phase of the Johan Sverdrup oil field development project in Norway.
A press release said that the award, worth approximately 110 million euros, is conditional upon finalization of the formal contract which is likely to take place within a few weeks. The cable system, which will offer a +/-80 kV HVDC solution, is expected to be ready for use in late 2019.
The cable will transmit power from the Norwegian power grid to the offshore oil field, the release said, adding that power from shore to the oil platform is an environmentally sustainable solution, significantly reducing carbon emissions from oil and gas production. Johan Sverdrup was described as among the five biggest oil fields on the Norwegian Continental Shelf.
“I am very pleased that we continue working with our long-term customer Equinor Energy AS,” said NKT President and CEO Michael Hedegaard Lyng. “I see the letter of award as proof of our premium DC technology capabilities and of our ability to provide turnkey solutions with NKT Victoria as a differentiator.” He added that the award further bolsters the company’s “leading market position in the oil and gas segment, which along with offshore wind and interconnectors represents good growth opportunities for NKT.”
Earlier in 2018, NKT completed supply and installation of the high-voltage DC offshore power cable solution for the first phase of the Johan Sverdrup development project. Installation was conducted by the NKT Victoria, operating at 600 meters depth, which marks one of the deepest installations of bundled high-voltage DC cables in the world. The Johan Sverdrup 1 solution from NKT now constitutes the world’s longest extruded offshore cable to an offshore oil and gas platform facility.
Nexans announced that it will provide 27 km of complex umbilicals with power, fiber-optic and hydraulic elements for the next development phase of the most prolific oil and gas field on the Norwegian continental shelf.
A press release said that Phase 3 of the Troll project covers the development of the Troll West structure, which lies in water depths of approximately 330 meters and is located 25 km north-west of the Troll A platform. The contract is from Equinor ASA, a multinational energy company based in Stavanger, Norway.
Nexans Norway will design, manufacture and supply static umbilicals that include high voltage power elements, high-pressure hydraulic lines, low-pressure hydraulic lines, a MEG (methanol and glycol) service line for chemical injection, a spare line and fiber-optic communications – all within a single cross-section. A 20-km umbilical will link the Troll A platform to Template W1, while a 7-km umbilical will then link Template W1 to Template W2. The contract also includes the supply of connections, terminations and other umbilical accessories.
Nexans offered Equinor a total “made in Norway” approach to the contract with the electrical and fiber optic elements manufactured at the Nexans Norway facility in Rognan, North Norway, while the complete umbilical system will be developed, manufactured and tested at Nexans Norway plant in Halden, Norway, the release said.
“Nexans has established an impressive track record in delivering umbilical projects for the Norwegian continental shelf and we look forward to continuing our long-standing relationship with Equinor by delivering this key contract for Troll Phase 3,” said Vincent Dessale, Nexans Senior Executive Vice President Subsea and Land Systems Business Group.
Nexans is scheduled to deliver the Troll Phase 3 umbilicals in the first quarter of 2020. First gas is expected from the project in the second quarter of 2021.
NKT reports that it has won a turnkey order of two high-voltage cable systems that will provide power availability and transmission security in the regions of Hedmark and Oppland in Norway.
A press release said that the contract calls for NKT to provide turnkey delivery of two 145 kV AC (alternating current) extruded cable system sets for the Mjøsa Project in the regions Hedmark and Oppland located North of Oslo in Norway. The order, from power grid operator Eidsiva Nett AS, will upgrade the grid in the region around Lake Mjøsa. It includes a total cable length of 35 km.
“We have great experience from several projects in Norway and we are excited to play a part in the continuous development of the Norwegian power grid,” said nkt President & CEO Michael Hedegaard Lyng, who noted that it will also support the integration of renewable.
The cables are to be manufactured this year at NKT’s facility in Karlskrona, Sweden, with commissioning set for 2019, the release said. It noted that nkt has extensive experience from projects in Norway and is currently executing on orders for the cable systems bringing power from shore to the oil and gas platforms.
