Grant Funding
Sheffield Forgemasters undertook OWGP’s foundation level business support programme, WEST. The business gained specialist market insight into the Floating Offshore Wind sector which highlighted opportunities for the business to enter the market. Following the WEST programme, Sheffield Forgemasters also secured OWGP grant funding to undertake a feasibility study into manufacturing structural castings for Floating Offshore Wind platforms. The study identified the sector as a viable market and the company restructured its business development strategy accordingly.

A closer look at Sheffield Forgemasters

Sheffield Forgemasters has a long history in pioneering components for Offshore Wind including the production of cast nodes. The company has a dedicated research and development team experienced in designing the optimal cast or forged component for highly stressed areas of structures, improving longevity by increasing their fatigue resistance. These optimised castings help to reduce fabrication time, allowing for the high volume production that the floating structures market requires.

Restructuring of business resources to focus on the Offshore Wind market.


Before engaging with OWGP, Sheffield Forgemasters had identified the Offshore Wind sector, particularly Floating Offshore Wind, as a new market for the business’s castings products. The company was seeking clarity on an approach to diversification, with a view to restructuring its business development strategy to enter the Offshore Wind sector.


Sheffield Forgemasters first secured consultancy support through OWGP’s business support programme, WEST. Through this programme, the business received one-to-one business support with market specialists to help the business deepen its understanding of the Floating Offshore Wind sector and recognise unique opportunities for Sheffield Forgemasters to enter the market.

Sheffield Forgemasters then successfully won grant funding from OWGP and used this to conduct a feasibility study into the manufacture of steel structural castings for Floating Offshore Wind platforms. The study focused on the viability of producing larger quantities of castings, which are smaller than the large, often bespoke, castings required in oil and gas structures.


A full assessment of the Floating Offshore Wind market enabled Sheffield Forgemasters to better understand the required cost improvements in serial production. The company restructured its business development strategy, bringing together relevant technical and commercial expertise to specifically target Floating Offshore Wind and now has dedicated resources for these new areas, focused on securing contracts in the field.

“OWGP’s business transformation programmes are a great asset to the UK supply chain and their funding was crucial in supporting Sheffield Forgemasters’ ambitious growth plans for the Offshore Wind market.”
