More than £1 million of funding has been put aside to help firms by giving them access to specialist support on developing sales strategy, processes and exploring new technologies.
Companies looking to break into or increase market share in offshore wind will be assigned a specialist advisor and can then tap into grants of up to £10,000 to help with improvement projects.
"There have been a significant number of investments in the marketplace and this has set the foundations for suppliers in the lower tiers to take advantage of new opportunities," explained Dominic Brown, head of GROW:OffshoreWind.
"Our role has been to work closely with industry leaders and manufacturers to develop a supply chain that is able to deliver a whole host of services and components to the world class standards expected by the big offshore wind contractors and tiers 1."
He added: "We've already allocated £7m of funding to support firms with capital investment, unlocking R&D and, in some cases, helping companies to relocate. This has led to million pounds of contracts being secured and thousands of jobs being safeguarded and created.
"The extension and additional money highlights the need to build on this platform and ensure manufacturers are continuing to be supported as more wind farms are announced."
GROW:OffshoreWind is delivered by Grant Thornton and programme partners the Manufacturing Advisory Service (MAS), RenewableUK and the University of Sheffield.
