Aker Solutions has invested in floating wind power technology company Principle Power forming an alliance that expands its position in offshore oil and gas field engineering into the fast-growing renewable energy market.

Aker Solutions has an extensive track record in developing offshore oil and gas fields, with particular capabilities in floating facilities. The partnership will help bring Principle Power's technology - a floating foundation for offshore wind turbines, known as WindFloat - to a broader market, says Aker Solutions.

Corrosion protection concept offers 30% cost saving

Experience to date on E.ON’s Arkona offshore windfarm project, the first use of a new corrosion protection concept, suggests that it is significantly less expensive than conventional techniques

As first highlighted in the 3rd Quarter 2017 issue of OWJ, the concept of using thermally sprayed aluminium to prevent corrosion is widely used in the offshore oil and gas industry but has only recently begun to be used in the offshore wind industry.

Corrosion protection and management of foundations for offshore wind turbines is a potentially costly undertaking in terms of initial capital outlay and in long-term maintenance. The current solution of paint and sacrificial anodes not only slows foundation construction time but has a limited lifetime that requires frequent inspection and maintenance activities. Anodes require additional secondary steelwork to be added to a foundation, and paint requires many days to dry, slowing production times and adding cost. The first application of thermally sprayed aluminium was on the Arkona offshore windfarm, for which the foundations have now been installed.

But it is not its height that makes this turbine special. It’s one of five emerging from the sea as part of Hywind Scotland – the world’s first floating windfarm.

“With floating wind, we’re trying to access deeper waters, particularly where there’s quite high wind speeds as wind is the fuel of the industry,” explains Rhodri James, a manager at the Carbon Trust.

UK engineering consultancy Atkins is to design the monopile foundations for Innogy’s 860MW Triton Knoll offshore wind farm off the UK east coast.

Atkins has been subcontracted by the foundation supplier – a joint venture between Smulders and Sif – to design 90 monopiles for the MHI Vestas V164-9.5MW turbines and two structures for the offshore substations.

New Concept for Offshore Wind Turbine Jackets

A new concept for a one-hundred-year minimum life concrete jacket foundation has been designed for offshore wind turbines.

Andy Filak, Principal of AMF Concepts, says that one of the major hurdles to the development of offshore wind farms has been the development of reliable foundation systems with long life and ease of installation in deepwater. Current concrete technology is not robust enough for the long-term exposure that is experienced in an ocean wind farm, he says, and steel technologies require complicated shoreside construction and at-sea installation involving multiple large crane barges and anchor handling tugs.

All 60 foundations have been installed in the seabed of the Baltic Sea ahead of schedule. The monopiles, which weigh around 1,200 tons, were tied up to 40 meters deep into the seabed. One success factor was the three-dimensional seismic investigation of the subsoil prior to installation.

Hywind Scotland, the world’s first floating offshore windfarm, has started to deliver electricity to the Scottish grid, having been formally opened by the First Minister of Scotland, Nicola Sturgeon.

The 30 MW windfarm, operated by Statoil in partnership with Masdar, is 25 km offshore Peterhead in Aberdeenshire, Scotland.

German energy company Innogy SE (ETR:IGY) said Tuesday it has acquired the 50% stake of Norwegian state-owned utility Statkraft in the 860-MW Triton Knoll offshore wind farm project in the UK.

"With full control over Triton Knoll, we will now develop the project further to final investment decision at our own discretion", says Hans Bünting, COO Renewables of innogy
