Livrables Documents, reports (20) Generalised tide-to-wire model The aim of this report is to develop a tide-to-wire model using blade element momentum theory (BEMT) to calculate the torque and thrust on a tidal turbine arising from turbulent inflow with a boundary layer. This will allow calculating the power take-off forces and the resulting electrical output from the turbine. RAM assessment report This report will describe the results of a reliability, availability and maintenability (RAM) assessment conducted on a generic tidal turbne. Critical systems and components will be identified. Based in scenarios defined by the consortium, sensistivity analysis of the impact of key choices will be assessed (component selection, electrical architecture, maintenance strategy,...). Dataset of synthetic load data available for WP4 and WP5 Datasets giving normalised, synthetic, load spectra for key turbine components (blades, shaft, bearings) under differing environmental conditions. The dataset will be made publically available on the Edinburgh University Data-share site and accompanied by a short report describing the data and explaining how it was derived. This collection of synthetic load conditions will be made available as basic information for the initial design of tidal turbines. To increased the potential impact on the industry the initial version of these datasets will be made available at the REALTIDE Workshop M27 Guidelines for the development of tidal turbines reliability databases This guideline will help the industry by providing a framework for a useful and reliable database on tidal turbines performance. Critical issues like proper taxonomy, data storage formats and confidential data treatment (anonymous data origin) will be taken into account. It will document conditions related to the recorded failure. Reduction of environmental impacts due to increased reliability This deliverable will establish a baseline for assessing the reduction in environmental impact derived of increasing reliability, through the full turbine life cycle. This document will include an evaluation on the environmental impact linked to the reduction on number of pieces substituted, reduction on the size of vessels needed, number of vessels operations and human interventions.
