This week saw the last of the 67 wind turbines being installed on the Dudgeon field and all of them are now producing electricity. During October, the wind farm will provide 410,000 homes in England with electricity.

Thirty-two kilometres off the coast of Norfolk in England the wind farm has grown gradually since the first turbine was installed at the beginning of the year. The wind farm was completed at the agreed time and below the budget of GBP 1.5 billion that was set when the investment decision was made in 2014.

Ever since the first households received electricity already at the beginning of February, all the turbines have joined the production, one by one.

When Dudgeon is fully operational later this year, Statoil will deliver electricity to one million brits from its offshore wind projects.

“It is wonderful to celebrate that all turbines are fully installed and the offshore operations have been carried out without any serious incidents. Efficiency during installations and completion has been excellent, and I am pleased to see that we are now producing,” says executive vice president for Technology, projects and drilling, Margareth Øvrum.

Building on Statoil’s expertise

“Dudgeon offshore wind farm is part of Statoil’s strategy of gradually supplementing our oil and gas portfolio with profitable renewable energy. Offshore wind has been a natural place to start, as we can build on our maritime expertise, experience from complex projects and our supplier chain. With Dudgeon in full production Statoil is well on its way to providing more than one million households in Europe with renewable electricity,” says Irene Rummelhoff, executive vice president for New Energy Solutions in Statoil.

The offshore wind farm will be operated from Statoil’s office in Great Yarmouth. The Sheringham Shoal offshore wind farm located 20 kilometres west of Dudgeon, is operated from Egmere.

Many lifts

The Dudgeon project started its 2017 marine season record-early. Already on 2 January, the Sea Challenger lifting vessel mobilized in Hull, England, and lifted the first four towers, the first four nacelles and the first 12 rotor blades on board to be installed on the field.

FACTS

  • With a capacity of 6 MW each, the 67 turbines on the Dudgeon field can provide 410,000 UK homes with electricity.
  • The Dudgeon Bank is located 40 kilometres off the coast of Norfolk in England.
  • Local suppliers account for more than 40% of the value creation in the Dudgeon project.
  • Dudgeon creates around 70 jobs in England – for 25 years ahead.
  • Statoil is the operator with a share of 35%. Statkraft and Masdar are partners with shares of 30% and 35% respectively.

Since then, the lifting vessel has returned to quay 17 times to pick up new turbine parts for the field. The turbines have been installed in turn: First, the tower was installed on the foundation, followed by the nacelle and finally the three rotor blades – four turbines at a time. The record for turbine installation is less than 18 hours, and the next day they were producing electricity for the grid.

Every turbine requires many lifts. The three tower parts were assembled onshore, then the tower, nacelle and blades were lifted on board the Sea Challenger, which installed the whole turbine on the field. A total of 335 heavy lifts were required offshore and just as many by the quay, in addition to the tower assembly on land.

In addition to Dudgeon, Statoil is operator for the Sheringham Shoal offshore wind farm in the UK, which has supplied electricity to around 200,000 homes since 2012. The world’s largest floating wind farm, Hywind Scotland, will come on stream during 2017. Statoil has furthermore a 50% share in the Arkona offshore wind farm in German waters, which is due to come on stream in 2019.

Scania installs largest solar roof in the Netherlands

Zwolle production unit gets solar-powered roof equivalent to the size of nearly eight football pitches, bringing it nearer to the goal of being carbon neutral by 2020.

Scania has taken its latest significant step in its transition to using exclusively renewable energy in its production activities.

The company’s production unit in Zwolle, Overijssel, will install the largest solar roof in the Netherlands. The solar roof will have 22,000 solar panels with a total energy capacity of six megawatts.

“Scania is committed to reducing its carbon footprint and throughout the organisation we are now taking initiatives similar to those in Zwolle to enhance energy efficiency. We have set ambitious targets and are well on our way to achieving carbon neutrality,” says Ruthger de Vries, Executive Vice President for Production and Logistics.

The roof is just one of several initiatives that Scania has taken in Zwolle for the production unit to reach carbon neutrality by 2020. One example is wind power. In September 2016, Scania Nederland started collaborating with the Dutch citizen initiative ‘Blauwvinger Energie’ and Windesheim College, to build three wind turbines by the Zwolle-IJssel canal, two of which are due to be built two of those wind turbines on the Scania factory area. The turbines for the project ‘Windenergie in Zwolle’ have a capacity of two to three megawatts each, while the hub height and rotor diameter of the turbines are 100 metres.

The solar roof has been welcomed by the local authority. “Scania is amongst those leading the way in energy,” says Annemieke Traag, Member of the Executive Council of the Province of Overijssel for Energy, Environment and European Affairs.

“As a major employer in our province, Scania is manifesting that it takes energy transition very seriously.”

In reaching its 2020 target, Zwolle would become the first Scania production in the world to become energy-neutral, but the company as a whole is committed to reducing its environmental footprint throughout its production processes. Scania is a signatory to the UN Global Compact, which has now been complemented by Agenda 2030 and its sustainability goals.

Vestas awarded its largest order to date in Sweden

APG Group and Vasa Vind, a HgCapital Renewable Partners company, have placed an order for 288 MW of V136-3.45 MW wind turbines, making the order the largest V136-3.45 MW order to date and the largest Vestas order ever in Sweden.

The firm and unconditional order comprises 80 V136-3.45 MW turbines delivered in Power Optimised Mode to 3.6 MW for the Åskälen wind park located outside Östersund in central Sweden.

Utilising the V136-3.45 MW in Power Optimised Mode to 3.6 MW, Åskälen wind park achieves increased annual energy production through the combination of larger rotor and high capacity factor, hereby demonstrating the strong fit of Vestas’ V136 turbine in the Swedish market.

“We are delighted to join forces again with Vestas for the construction of this major project. This high-efficiency turbine is another step forward in the relentless drive to lower the cost of wind power, and Vestas has proven once more to be an important partner in this journey”, said Annette Eriksson, CEO of Vasa Vind.

Klaus Steen Mortensen, President of Vestas Northern Europe, adds: “Delivering the V136-3.45 MW in Power Optimised Mode to 3.6 MW, the Åskälen wind project is a milestone for us and our largest project to date in Sweden. It is the result of a great partnership between APG, Vasa Vind and Vestas, working closely together to optimise the project across technology and economy. Combined with Sweden’s recent political agreement on the green certificate system’s future, the Åskälen wind park offers a strong business case towards investors.

The contract includes supply, installation and commissioning of the wind turbines as well as a 20-year Active Output Management 5000 (AOM5000) full scope operations and maintenance service agreement. Delivery of the first turbines is planned for the third quarter of 2019, while commissioning is expected in the beginning of 2020.
