FOREWORD

The offshore wind industry received a significant boost this spring with the dual announcements: firstly, the political agreement and action plan by North Sea countries on closer energy cooperation particularly in relation to offshore wind, and, secondly, a commitment by 11 of the leading energy companies that offshore wind can achieve a cost of €80MWh by 2025 given that the right policies and international co-operation are in place. These announcements set a target for the industry and provide the long-term stability for achieving that target. Thus, the requirement for achieving cost reductions is as strong as ever and this is good news for LEANWIND as there is a real appetite for the innovations being developed in the project.

Much of the LEANWIND work is now well advanced and each technical workpackage has developed either new technologies, design tools or models that will achieve cost reductions or help develop niche markets. The focus going forward will be to validate the benefits of the LEANWIND innovations and communicate them to the wider industry. Already there are a number of workshops planned to disseminate the LEANWIND output and I would encourage attendance of these events. Also, we will be releasing more information about the project innovations through public fora and publishing scientific papers to ensure maximum impact of the work.

LEANWIND set out with a very broad and ambitious work programme and it is very satisfying to see the project goals being achieved.

All the best,
Jimmy Murphy

WHAT IS LEANWIND ABOUT?

LEANWIND is a four-year project co-funded by the Seventh Framework Programme of the European Union. It will bring costreductions to the offshore wind energy industry through the application of lean principles to key aspects of an offshore wind farm and supply chain. It will do so by focusing on developing innovative technologies, procedures and tools that are directly
applicable and beneficial to the industry in the short to medium term.

PROGRESS & RESULTS

Construction, Deployment, and Decommissioning

The support structures and substructures necessary for offshore wind farms construction, deployment and decommissioning phases need to be improved. Among other objectives, this set of activities aims at ameliorating the temporary stability of structures during the deployment phase, designing new types of gravity bases to reduce installation time and at finding innovations concerning the seabed preparation.

GDG leading foundations work:  advancements in monopole design and gravity base structures to support offshore wind

Thanks to the support of the LEANWIND project, GDG have committed significant research resources to optimise offshore wind farm construction, deployment and decommissioning. Leading a group of consortium partners composed of offshore operators, project developers, contractors and O&M experts, they are developing novel new foundations concepts and enhancing existing foundation solutions.

Offshore monopiles appear to dominate the wind farm sector at present, with many developers promoting their use for upcoming projects and an industry trend for larger diameter monopiles in deeper water. The benefits of leaner and more efficient design approaches are clear to the entire industry, leading to significant CAPEX cost reductions.

GDG Managing Director, Paul Doherty, stated that “having recently implemented these new design approaches on offshore wind projects in the North Sea, we have seen these savings in practice, with the steel tonnage reducing by over 20% below the mudline”.  The GDG team have a wide experience base including geotechnical expertise, structural modelling and maritime engineering, which has been further enhanced through involvement of key staff members in joint industry projects such as the PISA monopile project led by Dong.  Over the next five years, as we strive for cost parity with conventional sources of energy, these optimised monopile design methods have a critical role to play.

The investigation on Gravity Base Foundations (GBFs) has been mainly aimed at improving the feasibility of buoyant concepts. The focus of this research has been on the detailed design of novel concrete structures, including geotechnical, structural and hydrodynamic analysis. Its output has shown concrete gravity structures to be viable in specific site conditions. A suite of parametric studies have also been undertaken to define the optimum geometric configurations for buoyant gravity structures – this is particularly useful to assist in FEED stage engineering design. In addition to the work undertaken within the LEANWIND project, GDG have been involved in the EDP led DEMOGRAVIT3 consortium which is currently in the detailed design phase of a novel concrete hybrid structure which will be deployed in Portugal next year. When commissioned next year, the DEMOGRAVIT3 project will be the first fixed structure deployed with the turbine pre-installed!

Novel Vessels and Equipment

Primary vessels types that are used for both wind farm installation and O&M need to be more efficient; LEANWIND aims at developing new solutions for vessels currently in use and at designing new vessels - tailored to meet industry requirements.

Operation and Maintenance strategies

O&M phases in the offshore wind farms are crucial. Procedures need to be optimised, especially in the far-shore, in deep water and other more exposed locations. This package of activities also wants to reduce OPEX costs by improving condition monitoring and remote presence systems, in order to minimize the need for on-site corrective maintenance.

Improving operation and maintenance of offshore wind with remote presence

The remote presence solution developed within LEANWIND by NA.AS is intended to be a low-cost method for checking the status of wind turbines to better know their condition and support decision making. Although useful for all turbines, this is especially beneficial to offshore turbines where reducing the need to travel to the site to do inspections are costly, time consuming and weather dependent.

The system consists of an instrumentation platform that moves on a rail installed inside the turbine and observe it on behalf on operators on land. Information can be gathered while the system is remotely controlled by an operator on land, or automatically without human intervention. Existing condition monitoring systems typically measure vibration, temperature and performance data. Remote presence have a different approach, and focus instead on information similar to what an operator on site would observe, e.g. video, sound and thermographic imaging.

A pilot installation of a stationary version of the system was performed in June of 2015, and ran for 6 months. A new test with a fully featured version of the system, shown in the picture below, is planned for autumn of 2016. This will be installed on a rail inside a turbine, and operate similarly as a commercial product.

Integrated Logistics

The final cost of energy produced by off-shore wind farms can be reduced by rendering the whole logistics system more efficient throughout the wind farm supply chain lifecycle – from installation and O&M to the decommissioning phase. The use of lean principles will help in defining the key industry challenges, analysing the separate parts composing the offshore wind supply chain – such as on-land transport and ports- and optimising them.

Economic and Market Assessment

The new results achieved by the project need to be placed in an economic context. LEANWIND  demonstrates that system optimisations and technology innovations have direct cost-saving benefits from which the whole wind industry will benefit. Offshore wind business and economic models that may encourage new sources of investment need to be examined. Moreover, the aim of the Economic and Market Assessment phase is to develop a commercialisation and implementation strategy that will ensure LEANWIND’s solutions to be effectively implemented.
