Xodus Group

Developing the Inch Cape Supply Chain Plan

Xodus Group (Xodus) supported Inch Cape in the development and drafting of its successful supply chain plan (SCP) for the fourth Contracts for Difference Allocation Round (AR4). Xodus worked to identify key impacts of the project’s existing supply chain, and community and skills engagement within the required framework, showcasing its benefits and priority actions realised. Xodus also provided guidance and support on the calculation of UK content, coordinating with the project’s key package managers.


The Xodus team was able to leverage the experience it had with Inch Cape’s AR4 SCP, for work on supply chain development statements (SCDS) for the ScotWind leasing round process, transferring its expertise into a different framework and narrative context. Xodus has since supported several offshore wind projects leveraging further experience and the team’s track record and shifting its offering to strategic and due diligence scopes.

Inch Cape provided important learning opportunities around challenges, potential barriers and suitable mitigation actions in the development of supply chain plan narratives. This, combined with the close and frequent communication with the Inch Cape team, also provided a supportive and fruitful environment for hands-on training of renewables consultants. Xodus appreciated the collaborative and coordinated approach with Inch Cape, enabling effective project delivery to a successful outcome.

Comment from the Commercial Project Manager in-post at the time: “Preparation of the Inch Cape Supply Chain Plan required very rapid assimilation of a huge amount of project information, followed by analysis and compilation of a comprehensive and persuasive plan against demanding timescales. Xodus achieved this and produced a high-quality plan which enabled a commitment to realistic targets and led to obtaining approval from government.”

Quote from the Xodus Project Sponsor:

 “Whilst the “fast track” requirements of this project were complex and multifaceted; Inch Cape was a pleasure to deal with and provided Xodus with timely provision of support and information for the duration of the scope. The successful completion of this scope, and the excellent relationship built, led to a further 18 months of project management and engineering support”.

Civil engineering work starting at project’s Cockenzie substation site

Civil engineering contractor, Careys is set to start work at the brownfield site of the former Cockenzie coal-fired power station on the East Lothian coast as the next phase of the Inch Cape Offshore Wind Farm substation construction gets underway.

Contracted by Siemens Energy, Careys will be responsible for the construction of the site infrastructure and the onshore substation, including its associated buildings, in readiness for the arrival of the electrical equipment including transformers and cables to transport the green energy generated by the offshore wind farm.

Initial groundworks were completed at the site in December 2023, and this upcoming phase of work will see the creation of further drainage at the site, laying of concrete bases, construction of internal roads and bunds, landscaping, and the erection of steel-framed buildings.

Residents along the construction traffic route will receive direct communication from the project on the construction programme and timings of key pieces of work, particularly any activity likely to include an increase in construction traffic or delivery of large loads and equipment.

Regular aerial drone surveys will be undertaken by local company Innovair, to monitor progress of the construction activity.

Inch Cape will comprise up to 72 turbines located 15 km off the Angus Coast and the power it generates will enter the national transmission system at Cockenzie. Once complete it will be one of Scotland’s largest offshore wind farms, generating enough green energy to power the equivalent of half the homes in Scotland.

ICOL, owner of Inch Cape Offshore Wind Farm, is an equal joint venture between Edinburgh-based renewable and sustainable energy company, Red Rock Power Limited and Ireland’s leading energy company, ESB.

Designing Inch Cape’s turbine foundations and substructures

SLPE is delivering the design of the wind farm’s wind turbine generator foundations and substructures. Since 2020, SLPE has been driving the development of concept studies, front-end engineering, and detailed design to inform significant project decisions such as the selection of substructure concept and associated design parameters. Currently in the detailed engineering phase, the SLPE team is working in close collaboration with the project supply chain to mitigate technical risks and complete the turbine substructure design package in readiness for the construction phase.


The SLPE design team comprises multi-discipline engineers, technicians, and project staff based in the UK. The Inch Cape contract award has enabled SLPE to grow its team size steadily over the past three years, recruiting and developing exceptional talent with experience in the design of offshore structures for UK waters and beyond. Not only has this supported the transition of a skilled workforce into the offshore wind sector, it has also encouraged technical innovation to overcome new challenges arising from the complex nature of the site conditions as well as ambitious aspirations for the wind farm.

Inch Cape and other similar wind farm projects have catalysed SLPE’s investment in industry research and development, including collaboration with British universities. An example of this is the company’s partnership with the University of Nottingham to develop an enhanced diagnostic monitoring system which will support the future life extension of wind farm installations. SLPE also actively invests in the development of proprietary technology that seeks to push technical boundaries in substructure and foundation design, adding value to projects such as Inch Cape.

Melvin Lau, Business Development Manager of SLPE said:

“Inch Cape is one of SLPE’s most important contracts. It has enabled us to invest in a highly skilled design team at the forefront of the offshore renewables industry. This has in turn benefitted Inch Cape with cutting-edge expertise and technology that seeks to maximise technical and commercial opportunities for the project.

“We are proud to be working alongside the Inch Cape team in a collaborative spirit to deliver this significant project for Scotland and the UK.”

ForeCoast Marine (JBA Consulting)

Using innovative planning software to optimise Inch Cape

ForeCoast®  Marine is a strategic and operational planning software system used by project designers, developers, owners and operators to design, optimise and manage complex offshore wind projects. It was developed in-house in the UK by JBA Consulting (JBA) – a family of environmental, engineering and risk management companies and one of the world’s leading consultancies in this field.

ForeCoast®  Marine has been utilised by Inch Cape to inform the project’s offshore installation phases and help shape the design of the project.  The software system has simulated the project’s key offshore asset-component installation phases including: foundations, inter-array cables, offshore substation platforms, export cables and wind turbine generators.


Through these simulations, the performance of proposed strategies will be compared quickly and reliably against key metrics such as capital expenditure, operational expenditure, programme and weather, technical or logistical downtime.  This will help to de-risk the project, maximise its performance and ultimately increase profitability. The innovative simulation software allows multiple strategies to be compared efficiently and robustly, shaping the project in many ways, potentially saving time and money.

The Inch Cape work has given the company valuable modelling experience for all stages of construction of an offshore wind farm (foundations, turbines, inter-array cables and export cables). It has also helped streamline elements of the work including the key model input template.

Laurie Wilkinson, Senior Met Ocean Analyst said:

“It has been interesting and enjoyable to work closely with the Inch Cape installation team. They are engaging and personable, yet they challenge us constantly and are diligent in their work. We have learned a lot about what is important to making their project a success in the process.”
