Samenvatting:
In 2000, ECN has defined a long term R&D program with the ultimate aim to lower the O&M (Operation and Maintenance) costs of offshore wind farms. Part of this R&D program focuses on the development of models to quantify and optimise the O&M aspects in the planning phase of wind farms. This has resulted in a software tool with which project developers of offshore wind farms are able to estimate the annual average O&M costs. The model takes into account (1) the failure behaviour of turbine components in terms of failure frequencies and associated repair actions; (2) the access vessels and hoisting equipment; and (3) the wind and wave cli-mate at the intended location.
Germanischer Lloyd Industrial Services GmbH, Business Segment Wind Energy (GL Wind) validated the software as a third party. As GL Wind has realised that the financial issues will play a more important role as the project size for wind farm projects increases. Thus validated software will give more security for the developers applying the software tool and for the financers and insurance companies relying on the results of the software tool.
This paper describes ECN's O&M Tool. Second, the paper presents the results and the reasons of the validation, including the description of the limitations and benefits of the software tool. Finally, the paper discusses in a more general way the use of tools to estimate O&M costs during project development and project certification.
