Norwegian Electric Systems AS (NES) has been contracted by Green Yard Kleven in Ulsteinvik, Norway to develop and deliver the complete energy design, an integrated automation system and its future-oriented bridge system for a Field Support Vessel the Norwegian shipyard is constructing for Romanian integrated energy company OMV Petrom S.A.

NES will supply frequency converters and electric motors for the propulsion system, battery system, transformers and its proprietary Quadro Master switchboard – a DC power distribution switchboard that enables the use of variable speed generators. The Quadro Master is supported by NES’ Odin’s Eye, enabling a DC-ring system configuration. NES will also deliver its integrated automation system – IAS – and own navigation system, RAVEN INS, developed in-house to meet the highest standards of modern maritime operations. The system will be delivered with a CBT notation (Closed bus tie).

“According to DNV, closed bus-ties have emerged as a viable solution to enhance energy efficiency. These allow the integration of DP power systems and reduce the number of generator sets that need to run simultaneously. This leads to optimized power-sharing, reduced fuel consumption and emissions, fewer engine hours, and lower maintenance costs. Additionally, a system with active and reactive power-sharing across bus ties can mitigate and reduce the consequences of certain failure modes,” says Siv Remøy-Vangen, managing director of Norwegian Electric Systems.

First deliveries will be made in the second quarter of 2025, with final deliveries and commissioning being undertaken in the second quarter of 2026.

The newbuild Field Support Vessel will operate for the Neptun Deep project, which is the largest natural gas project in the Romanian Black Sea and the first deepwater offshore project in Romania. The ship will be an 89.5-meter-long multihull vessel, with W2W (Walk to Work) walkway, offshore crane, and furnishings for a total of 90 people in single cabins. The ship is to be delivered in the second half of 2026.

“We are happy to have NES with us on this important contract, and we are really looking forward to the collaboration. We rely on partnerships with suppliers such as NES who can challenge us and ensure predictable project execution,” says Hans Jørgen Fedog, general manager at Green Yard Kleven.

“Green Yard Kleven has taken over what is one of Norway’s oldest shipyard including a long track record and delivery of high quality vessels. To see newbuilding activity again at their facilities in Ulsteinvik is a true joy. In addition, Green Yard Kleven has an ambitious target of being the greenest alternative in the industry. I therefore consider being chosen as key supplier for this project to be a recognition of NES’ sustainability profile and our role as enabler of green transition at sea,” adds Siv Remøy-Vangen.

NES is a subsidiary of HAV Group ASA, which is listed on Euronext Growth Oslo. NES has operations in Bergen (HQ), Egersund and Ålesund in Norway, and Istanbul, Turkey.
