Spare Parts Management in Offshore Wind: Leveraging Good Practice from the Aerospace Industry

02 Jun 2017

Spare parts management is a critical element of the successful implementation of offshore wind farm operations and can contribute to cost reductions. Accenture's application of data analytics, process innovation and enhanced supplier collaboration has overhauled the spare parts management strategy of a major aerospace client, with much of the knowledge and experience accumulated applicable to the offshore wind sector. In this O&M Case Study, Conaill Soraghan and Andy Lewin focus on Accenture's spare parts optimisation journey, and establish how its practices can be applied to offshore wind.

Service Operating Vessel Logistics at Dudgeon

23 May 2017

Located around 20 miles off the Norfolk coast, Dudgeon Offshore Wind Farm presents a host of logistical challenges for its Owner/Operators. With journeys to the wind farm lasting up to two-and-a-half hours, transit times and weather windows mean that a relatively untested service operating vessel logistics strategy has been put in place. In this O&M Case Study, Owner/Operators Statoil, Statkraft and Masdar share their experiences of implementing a novel logistics strategy with Sally Shenton.

E.ON and Uniper Engineering Academy's Offshore Wind Apprenticeships

23 May 2017

After identifying a lack of technicians available to maintain its growing offshore wind fleet, E.ON collaborated with the Uniper Engineering Academy to devise an apprenticeship scheme that will deliver a sustainable pipeline of engineers. This O&M Case Study, by Dr. Conaill Soraghan and Sally Shenton, examines how the programme was developed, and how it has been tailored to prepare prospective technicians for the demands of working offshore.

Moving Toward a Subsidy-Free Future for Offshore Wind

28 Apr 2017

The recent offshore wind auction in Germany was a landmark moment for the industry. DONG Energy's winning zero-subsidy bid sends a clear signal that offshore wind has established itself as an important part of a sustainable, long-term energy mix and that, given the right conditions, it can be delivered without ongoing revenue support. In this paper, ORE Catapult Financial Analyst Gavin Smart examines the technological developments, strategic decisions and assumptions required to enable the economic buildout and operation of subsidy-free offshore wind in Germany by 2025.

Helicopter Crew Transfers at Westermost Rough

11 Apr 2017

As wind farms move further offshore, the logistical challenges around O&M are becoming more complex. Longer journeys by crew tranfser vessel reduce the amount of time that technicians have to undertake work on the turbines: a problem that can be compounded by short weather windows. When DONG Energy contracted a helicopter to support its O&M logistics at Westermost Rough, it became the Danish company's first wind farm in the UK to use such a strategy. This O&M Case Study looks at DONG's approach, the key advantages and disadvantages of using helicopters in offshore wind, and the challenges and lessons learned.

The Economic Value of Offshore Wind: Benefits to the UK of Supporting the Industry

28 Mar 2017

The UK offshore wind industry is going through a period of rapid cost reduction, brought about by innovative technological solutions and underpinned by a growing and maturing industry, together with continued Government support. The UK Government is expecting not just clean energy capacity but also projects that deliver economic benefit to the UK. By looking at the relationships between revenue support and the economic benefits of an active UK supply chain, there is a clear net benefit to the UK from investing in the offshore wind industry, both to serve UK projects as well as bolstering the potential to export skills, products and services to the global market.

Wind Turbine Condition Monitoring: Data Processing and Power Quality Requirements

13 Jan 2017

Deployed in remote locations and subject to harsh ocean conditions, offshore wind turbines are difficult – and expensive – to maintain and keep in healthy condition. This paper by Othmane El Mountassir, an Electrical Project Engineer at ORE Catapult, addresses the main challenges surrounding current condition monitoring systems, and looks at the way forward.

Offshore Wind Cost Reduction

03 Nov 2016

Recent strike prices awarded in the Netherlands and Denmark have made headlines throughout the offshore wind industry - in some cases, 60–70% lower than the lowest prices awarded in the UK. In this paper, ORE Catapult's Investment and Financial Analyst Gavin Smart examines the reasons behind this gulf in cost, and provides a bridge between the levelised cost of energy for UK offshore wind farms and their European counterparts.

Cost Modelling Analysis of Floating Wind Technologies

27 Oct 2016

Are floating turbines a cost-competitive solution to harnessing the UK's enormous deep-water offshore wind potential? This paper explores the commercial viability of floating wind technology by carrying out a cost modelling analysis of TLPWIND, an innovative tension leg platform solution developed by Iberdrola E&C, in partnership with the University of Strathclyde and ORE Catapult.

An Alternative End-of-Warranty Contracting Strategy

20 Oct 2016

In 2013, Centrica reviewed the costs and benefits it received from the warranty-based operations and maintenance (O&M) service contract for the Lynn and Inner Dowsing (LID) offshore wind farms. This case study focuses on the project that Centrica implemented to develop the end-of-warranty contracting approach, the new approaches adopted to O&M activities in the post-warranty period, and the key benefits that have emerged as a result.

BLEEP: Reducing the Cost Impacts of Wind Turbine Blade Erosion

16 Aug 2016

One of the main issues facing the offshore wind industry is blade leading edge erosion (LEE), which can occur in a little as two years of operation and can affect the performance and structural integrity of wind turbines. ORE Catapult’s Blade Leading Edge Erosion Programme (BLEEP) is coordinating research to improve understanding on how to manage and prevent this issue to reduce the cost of energy impacts by facilitating collaboration between industry and the research community.

Self-Performed O&M at Robin Rigg: A Strategic Approach to Planned and Reactive Maintenance

29 Jul 2016

In December 2014, the turbine warranty period and initial service contract at the Robin Rigg Offshore Wind Farm ended. The wind farm owner, E.ON, decided to take all operations and maintenance in-house in a strategy it calls ‘self-perform’. Through first-hand interviews with the Robin Rigg operations team, this case study describes the building blocks required to implement this strategy and explains the key benefits and lessons learned.
