Atkins produced the detailed design for E.ON’s Humber Gateway offshore wind farm’s offshore substation support structure.

Atkins produced the detailed design for E.ON’s Humber Gateway offshore wind farm’s offshore substation support structure. Harland and Wolff Heavy Industries Limited delivered E.ON with a full design and build package with Atkins subcontracted for the module support structure design. This project was awarded to Atkins because of our geotechnical expertise and capability to develop feasible foundation designs for the chalk ground conditions.

The offshore substation platform substructure consists of two components; a piled jacket and a module support frame (MSF) that was lifted onto the jacket substructure on site. All work was performed with due consideration to the difficult ground conditions and a key project requirement to enable installation using the project’s jack-up vessel – the MPI Adventure – which imposed restrictive load curve limits on geometry and weight. This enabled the developer to make optimal use of long term charter arrangements and mitigate installation risks.

The MSF provides support and allows access to two topside modules. The modules are connected to the foundation through eight support points, four per module. The modules connect to the wind farm by eight array cables each and are connected to land by one export cable each.

Atkins conducted:
• Full in-place, load-out, transportation analyses
• Lift structural analyses for both structures
• Fatigue, ship impact and on bottom stability analysis for the jacket substructure
• Detailed design drawings based on calculations for fabrication at Harland and Wolff’s shipyards in Belfast.

The work took place during 2013, and was completed in 2014.

Humber Gateway is located in the northern part of the Greater Wash area. The site is around 8km east of the Yorkshire coast near the Humber Estuary in the North-East of England. The wind farm has an installed capacity of 219MW, consisting of 73 3MW Vestas V112 turbines and a single twin circuit 33KV to 132KV substation. The wind farm provides 170,000 homes with green power.

  • We are helping to enable a production line approach to fabrication, rather than a bespoke solution each time, driving down the whole life costs to DONG Energy whilst maintaining the highest safety

    Atkins has contracts for detailed engineering design of offshore substation platforms (OSPs) at DONG Energy construction projects around the UK;

    • one substation at the Burbo Bank Extension offshore wind farm in Liverpool Bay
    • two substations at the Race Bank offshore wind farm off the north coast of Norfolk
    • and two substations at the Walney Extension offshore wind farm off the coast of Barrow-in-Furness in the Irish Sea.

    In 2015, we were awarded a contract for engineering design services for three offshore substations with helidecks and refuelling systems for DONG Energy’s proposed Hornsea Project One offshore wind farm, taking the total number of OSPs that Atkins is designing to eight.

    With over 30 years looking after oil and gas offshore structures, we can directly apply lessons learned in terms of construction and operation in deeper waters, foundation and jacket technology, the use of heavy-lift vessels and asset maintenance offshore. Our UK based team will be working together with DONG Energy to apply the lessons on these large, complex projects enabling us to set new benchmarks in stripping out any fat for an industry that needs to become more and more competitive with other energy sources.

    DONG Energy is progressing to a standardised wind farm, reducing the costs of offshore wind energy by 35 - 40 percent for projects getting the go-ahead in 2020.

  • We’re providing specialist design and engineering support to help Tidal Lagoon Swansea Bay Plc create the world's first power-generating tidal lagoon in Wales, UK.

    The project will see low carbon electricity generated by closing off a tidal sea area and incorporating hydro turbines through which the sea moves to generate power. With a 320MW installed capacity and 14 hours of reliable generation every day, Swansea Bay Tidal Lagoon will capture enough renewable energy to power over 155,000 homes for 120 years.  It is also hoped that a blueprint will be established for the rapid roll-out of a new form of home-grown and built, low carbon energy infrastructure in the UK.

    As the client’s chief engineer, Atkins is producing outline designs for the breakwater, turbine house and ancillary works and supporting the tender process by helping develop documents and reviewing responses and detailed designs. Once a design and build contractor is appointed and construction work starts, scheduled for Spring 2015, we will also provide a range of site supervision, auditing and technical checking services.

  • Atkins’ carried out the detailed design of the topsides for the Galloper Wind Farm Offshore Transformer Platform with the complete topsides expected to be in the order of 1,600 tonnes.

    Atkins’ design of the offshore transformer platform (OSP) incorporates all of the temporary construction, transportation, installation and commissioning conditions, including the complex sequential pull-through of multiple submarine cables for connection to the OSP equipment.

  • Atkins has signed a Memorandum of Understanding (MoU) with Scottish and Southern Energy PLC (SSE) to join a framework of key suppliers to help to drive efficiencies in its offshore wind programme.

    Atkins’ role includes the provision of expert engineering design advice as part of an alliance of leading companies who are supporting SSE in its drive to boost its renewable energy provision.

    The supplier framework will form an offshore wind alliance designed to help secure substantial reductions in the cost of delivered power from offshore wind farms.

    The alliance brings together leading players in offshore wind and offshore oil & gas, with vast experience in energy, engineering and construction.
