en.Wedoany.com Reported - Entr and its wholly-owned subsidiary Unitech Power Systems have been awarded a contract by Nadara to conduct power infrastructure studies for the 1.8GW Bellrock floating offshore wind farm in Scotland.
European renewable energy producer Nadara plans to develop this floating offshore wind project approximately 120 kilometers off the coast of Aberdeenshire in the North Sea. Entr is the consulting business unit of Aker Solutions. The work will focus on developing an overall concept for the project's entire transmission system, covering the full process from offshore power generation to onshore grid connection. The study will support the identification of optimized power infrastructure solutions for the Scottish offshore wind farm, involving areas such as inter-array submarine cables, offshore and onshore substations, export cables, and grid integration. It will also evaluate the relative merits of various transmission configurations in terms of technical feasibility, cost, schedule, and supply chain availability.
Entr and Unitech Power Systems will provide insights to Nadara to support the procurement strategy and decision-making for the Bellrock offshore wind farm, and will continue to provide support as the project progresses to subsequent design, approval, and investment milestones. According to Aker Solutions, Entr will draw on project execution experience and operational data. Unitech Power Systems specializes in power engineering and system analysis, helping to define robust, efficient, and grid-compliant electrical architectures for proposed solutions. The joint work will inform a range of project and investment options throughout the development process.
Nadara stated that conducting comprehensive studies at an early stage aims to mitigate risks such as cost overruns, schedule delays, and technical uncertainties. Dorthe Kirkeby, Vice President of Ocean and Wind Power at Aker Solutions Entr, noted that floating offshore wind plays a significant role in the energy transition, and robust early-stage design is key to advancing the project with confidence. For a project of this scale, early definition of the transmission system is critical for managing cost, schedule, and technical risks. Through Entr and Unitech Power Systems, project execution insights can be combined with deep power engineering expertise to help identify practical, optimized, and future-proof concepts for Bellrock. The contract scope also includes determining procurement timelines and potential local supply chain participation, reflecting the ambition to support the growth of the floating offshore wind industry in Scotland and the UK.
David Robertson, Portfolio Director at Nadara, stated that this study aims to make the right technical decisions as early as possible. By partnering with Entr and Unitech Power Systems, strong offshore project experience and specialized electrical engineering capabilities can be brought together at a critical stage of Bellrock's development. This work will help evaluate the most robust and efficient transmission options, understand key cost and project considerations, and build a stronger evidence base for future investment and procurement decisions.
As part of Crown Estate Scotland's ScotWind leasing round, the Bellrock offshore wind farm will provide electricity equivalent to the demand of over 1.7 million households, offsetting more than 1.8 million tonnes of CO2 emissions annually. Its design is expected to include up to 132 floating wind turbines (depending on turbine size), along with associated floating foundations, mooring systems, anchors, inter-array and export cables, and offshore substations. The electricity generated by the floating wind farm is planned to come ashore between Findon and St Cyrus, and connect to SSEN Transmission's Hurlie substation west of Stonehaven in Aberdeenshire. Further engineering work on offshore and onshore transmission infrastructure components is ongoing, including continuous surveys, site selection activities, and stakeholder engagement. Nadara, through the project holding company Bellrock Offshore Wind Farm, submitted a Section 36 consent and marine license application for the wind farm development area in April 2026.
