Hitachi Energy sub-sea transmission network to connect ADNOC offshore operations to onshore power grid

Hitachi Energy has won a major order from Samsung C&T Corporation in the UAE to connect ADNOC’s offshore operations to the onshore power grid owned and operated by the Abu Dhabi National Energy Company.

Hitachi Energy said its HVDC Light technology and MACH digital control platform will enable the transfer of cleaner and more efficient power from the mainland to power ADNOC’s offshore production operations, enabling a carbon footprint reduction of ADNOC’s offshore operations by more than 30%.
Hitachi Energy’s statement added: “This innovative solution reinforces Hitachi Energy’s commitment to helping customers and countries to transition towards a carbon-neutral future and help enable the ‘2050 Net-Zero Initiative’ of the UAE.”

With a capacity of 3,200 MW, the two HVDC (High Voltage Direct Current) links will be by far the most powerful power-from-shore solution in the Middle East and North Africa region to date and also the first HVDC power-from-shore solution outside Norwegian waters.

Claudio Facchin, CEO of Hitachi Energy, said: “We are proud to be enabling Abu Dhabi and ADNOC to make significant progress on their pathway toward achieving the United Arab Emirates’ ambition to be carbon-neutral by 2050. At Hitachi Energy we are championing the urgency of the clean energy transition, and this major order is further evidence that we are a ‘go to’ partner for developing and deploying technologies and solutions that are advancing the world’s energy system to be more sustainable, flexible and secure.”

SH Kim, procurement manager at Samsung C&T Corporation, added: “In Hitachi Energy, we have selected a trusted partner who brings deep global competence and a strong mindset of collaboration and innovation. Together, we will serve ADNOC with pioneering technologies that are proven to deliver for such a large HVDC project.”

The entire power-from-shore project will comprise two HVDC power links, which will connect two clusters of offshore oil and gas production facilities to the mainland power grid, a distance of up to 140km for each cluster.

Hitachi Energy is supplying four converter stations, which convert AC power to DC for transmission in the subsea cables, then reconvert it to AC from DC for use in the offshore power systems. The HVDC technology will be supplied from Hitachi Energy’s global competence centres. Also included in the order are system studies, design and engineering, supply, installation supervision and commissioning. Hitachi Energy will support the customers with a long-term life-cycle service agreement leveraging digital technologies to ensure system availability and reliability over the HVDC links’ long operating life.

Hitahci Energy said that its HVDC Light is a voltage source converter technology that was pioneered by Hitachi Energy. It is the preferred technology for many grid applications, including interconnecting national power grids, integrating offshore wind parks with mainland transmission systems, feeding more power into congested city centers, interconnecting asynchronous networks that operate at different frequencies, and power from shore.

HVDC Light’s defining features include a compact converter station, which is important in space-critical applications like offshore wind, offshore production facilities and city-centre infeeds, and low electrical losses as well as black-start capability to restore power after a grid outage.
