The contract, which also has options to extend for a further two-year period, will see the engineering, procurement, construction and commissioning (EPCC) specialist providing a wide range of key support across the developer’s windfarms in the United Kingdom, The Netherlands, Sweden and Denmark.

Now in its 20th year, PD&MS is a multi-discipline EPCC contractor and has been delivering mid-value capital projects, O&M, general modifications, upgrade projects, late life asset management and decommissioning services across the energy sector. It currently employs around 550 in Scotland and 100 overseas, with operations in Aberdeen, Glasgow Azerbaijan.

Thomas Barter, head of renewables business development at PD&MS, said: “We are thrilled that Vattenfall has recognised our highly transferable skills gained from years of successfully operating across oil and gas and other energy sectors and chosen us as one of their long-term service providers.

“This new contract solidifies PD&MS’ position as a key supplier for future wind developments, such as ScotWind and other future European projects.”

As well as expanding its offshore wind clients’ portfolio, PD&MS was recently granted ORE Catapult’s Fit 4 Offshore Renewables status for its EPC services. The programme was developed to help the UK supply chain to reconfigure and deliver services in the offshore renewable energy sector. In the last 12 months, the business has also acquired low carbon engineering specialists Synergie Environ and front-end consultancy Optimus.

Mark Davidson, project director and energy transition leader at PD&MS, added: “Winning this three-year minimum contract with Vattenfall following a competitive tender process is testament to our team’s connected competencies which match the disciplines needed by offshore wind.

“We have an extensive track record for delivering innovative and cost-effective project solutions which have proven to reduce cost and maximise asset uptime to create significant ongoing value within the offshore renewable energy sector.

“Underpinned by our flexible proactive culture we are well placed to further service the UK and European decarbonisation agenda.”
