MEMBER NEWS: From oil rigs to floating wind – work starts on Ardersier Port transformation

In the 1970s Ardersier – a vast and currently unused port 14 miles east of Inverness – was one of the largest oil rig fabrication yards in the world, employing up to 4500 workers.

At over 400 acres (162ha) and with more than a kilometre of quayside, Ardersier is the largest brownfield port in the UK.

Now new owners are transforming Ardersier Port into Europe’s first fully circular Energy Transition Facility – recycling the oil rigs of the past to make foundations for future fleets of floating offshore windfarms. It is anticipated thousands of long-term jobs will follow.

Work is about to begin on a £20 million, nine-month ‘capital dredge’ – removing 2.5 million cubic metres of sand (equivalent to 1000 Olympic swimming pools) – which will open up the massive port once more.

Over the next five years the port’s owners will deliver:

an oil rig decommissioning facility,
a waste from energy recovery facility designed specifically to deal with special wastes
a £300 million green steel plant, powered by offshore wind and energy from waste
a concrete production plant utilising dredged sand from the port, and by products from the steel plant and energy from waste facility
a dedicated floating wind hub for concrete floating wind foundation manufacturing.
This will create the largest floating wind foundation fabrication, manufacturing and assembly facility in the UK – in an offshore wind market predicted to deliver 29,000 jobs and £43.6 billion to the UK economy by 20501.

Already Ardersier Port has an agreement with floating wind leader BW Ideol, guaranteeing them exclusive access to the port for the manufacture of their concrete floating wind foundations.

Once the dredging is complete next summer, Ardersier Port will build a bespoke slipway which will allow floating oil and gas structures to be hauled onshore prior to removing all contaminants and decommissioning them.

Last week a report by industry body Oil and Gas UK2 estimated there will be more than a million tonnes of North Sea topsides coming ashore this decade, much of which can be recycled.

Ardersier Port owner Steve Regan said:

“The UK has set a world leading net zero target to build back better, support green jobs and accelerate our path to net zero. At Ardersier we can lead the UK’s Green Industrial Revolution by using circular economy practices to deliver new low carbon infrastructure built on the by-products of our oil and gas past. This is a once in a generation opportunity to create a world-leading industrial and offshore wind manufacturing facility here in the UK.

“It is a simple plan where each element makes commercial sense as a stand-alone project – but when combined, the benefits to the economy, and the environment, are multiplied,” Regan concludes.

Ardersier Port owner Tony O’Sullivan said: “The energy transition from offshore structures to floating wind has an important missing factor: steel. Today, the UK exports ten million tonnes of scrap steel annually. By building a new renewable-powered electric arc furnace at Ardersier Port, the first new-build steel mill in the UK for 50 years, we will utilise a million tonnes of scrap each year. This will produce reinforcement steel for the UK construction industry, of which there is currently a shortfall, allow for the onsite construction of floating wind platforms, and enable us to export green steel to global markets.

“This strategic approach has been backed by a recent independent report by Zero Waste Scotland3 and once complete, our green steel mill will be revolutionary: it will be the only place in the world where the scrap from decommissioning is processed into steel. Once operational, this plant alone will generate 300 high quality permanent low carbon jobs.”

BW Ideol is one of three partners (together with Elicio and BayWa r.e) in the Floating Energy Allyance which has submitted applications for offshore wind development rights in the ScotWind leasing round run by Crown Estate Scotland, with a decision due early next year.

The Allyance has pledged to manufacture all its floating concrete foundations in Scotland, creating almost 4000 jobs.

BW Ideol’s CEO, Paul de la Gueriviere says: “The lack of large infrastructure is a bottle neck to deliver the number of floating foundations required for the UK market’s ambitious development plans, both in terms of local content and the production rate expected. Ardersier Port is a unique facility to unlock these constraints.

“In comparison to steel foundations, floating wind offers a unique opportunity to combine both price competitiveness and local manufacturing, thanks to BW Ideol’s unique concrete floater solution. As an early mover in the market, we have engaged with the port’s owners for several years, sharing a joint vision to create a circular and sustainable local supply chain.

“By securing exclusive access to Ardersier Port, BW Ideol is reaffirming its commitment to manufacture its floating foundations locally, maximizing the benefit for Scotland and the rest of UK, without conditions.”

Gavin MacKay, Head of Energy Industries at Highlands and Islands Enterprise says: “We are encouraged to see Ardersier Port being actively developed to support the offshore energy industries. This was the original purpose of the site and one to which it is still well suited. Offshore wind, in particular, is poised for significant growth, and the facility offers real potential for the local production and assembly of the large components that will be required by that industry. We look forward to working alongside Ardersier Port and their strategic partners in pursuit of their goals.”

The plans at Ardersier have been welcomed by OGUK, which represents the UK’s offshore oil and gas industry and whose members include Ardersier Port.

Joe Leask, OGUK’s Decommissioning Manager, said: “Facilities like Ardersier will play a crucial role in supporting the UK’s decommissioning sector and our transition to a low-emission economy.

“The North Sea Transition Deal our industry has signed with the government commits us to help the nation cut its emissions. That will include building thousands more wind turbines, plus facilities for capturing CO2 and producing hydrogen from natural gas – all requiring new offshore infrastructure.

“At the same time, we are decommissioning many ageing oil and gas industry assets from which we will recover more than 100,000 tonnes a year of steel. Projects like Ardersier will help create a circular economy where, instead of generating waste, these old structures become the foundation for the nation’s energy future.”

Earlier this month the UK Government announced up to £160 million in new funding to kickstart the rollout of large-scale floating offshore wind ports and factories across the country, and it is expected Ardersier Port will bid for these funds.

Ardersier Port is owned by Steve Regan, a former chief executive of civil engineering firm Careys, and business partner Tony O’Sullivan. They set up Ardersier Port (Scotland) in May and registered the business in Fraserburgh. They purchased the site earlier this year. The acquisition fee was not disclosed.

The last greenfield steelworks installation in the UK was the Sheerness Steelworks, on the Isle of Sheppey, Sheerness, commissioned by owners Co-Steel in 1972.

AREG is the original energy transition organisation, working on behalf of members to empower the energy supply chain and champion its expertise. Please get in touch if you have any questions or would like to find out more about membership.

AREG has played an important role in the growth of Scotland’s renewable energy sector, engaging the supply chain and developing the European Offshore Wind Deployment Centre. However, we are only at the very beginning of the transition that AREG was established to both lead and support so there are still opportunities for companies to get into the constantly evolving renewables supply chain. We look forward to continuing our work together as renewables builds on its place as Scotland’s main source of power, and as we seek to deliver real change in the crucial areas of heat and transport.

Aberdeen & Grampian Chamber of Commerce has worked closely with AREG since its formation. The recent progress in the developments of offshore wind projects by Equinor and Vattenfall are as a result of the work of the group over many years. The north-east is known as the oil and gas capital of Europe. At the Chamber, we believe the region must evolve its position to being recognised as the energy capital. Whilst hydrocarbons will continue to be essential in driving our economy for years to come, the generation of renewable resources will play an increasingly important role in providing cost-effective power, innovative development and economic growth.

The enthusiasm and dedication of the early group that would become AREG was fundamental in us choosing to launch All-Energy in Aberdeen. The first tiny show was held in 2001, and AREG’s Chairman at the time, Jeremy Cresswell, played such an active role that I often describe him in terms such as All-Energy’s ‘midwife’. All-Energy is now the UK’s largest renewable and low carbon energy exhibition and conference in terms of number of attendees, space booked, and number of exhibiting companies. As AREG became firmly established, their presence and support for the event grew spectacularly over the years. We thank them most sincerely for their invaluable input.


Vattenfall has forged a strong working relationship with AREG through the development of the European Offshore Wind Deployment Centre. AREG has worked tirelessly on behalf of the North East and it can take enormous credit for the growth of sustainable energy in the region and the path it has cleared for the region to capture further investment.


Aberdeen City and Shire is emerging as a key location for renewables by successfully transferring its world-class oil and gas expertise into the sector and AREG has done much to advance this through a broad range of initiatives. It has acted as a catalyst in driving further investment in the local economy by engaging with companies, Government, public bodies and existing projects and we have been pleased to support their efforts. Scottish Enterprise will continue to engage with AREG as we increase Scotland’s use of renewable energy.
