Deliverables

Development of models and operational framework

This deliverable will outline the models and design frameworks, which will be developed to assess the LIFTWEC concepts and is primarily linked to Task 7.4. The installation strategy design framework developed to review the concept designs and identify viable installation strategies will be fully described. Similarly, full details will be provided on the decommissioning strategy design framework. For O&M, the reliability assessment methodology will be described, including a summary of the various reliability assessment approaches that were assessed. The reliability assessment methodology adopted will be fully detailed and will include reasons its selection. This deliverable will outline how existing UCC in-house models were modified to model the lifetime operations of the LiftWEC concept. These models comprise of three separate modules that simulate installation, O&M and decommissioning activities. This deliverable will contain a full description of these models. Including their functionality, development history the model validation & verification processes undertaken during their development.

Review of current liftbased WEC concepts and specification of preliminary configuration

This is part of Task 2.3. This will consist of a report that reviews the current lift-based WEC concepts and describe the configuration specifications that will be used in the preliminary numerical and physical models, as well as for the design development. The specification will be provided in sufficient detail to ensure that the configurations are unambiguously defined.

Operational design considerations

This deliverable is linked to Task 7.1 and will contain a set of key design considerations for the LIFTWEC concept, which will feed into the concept development and evaluation work package. This will ensure that the major operational factors, which are likely to, adversely affect the viability of the concept can be considered early in the design process and be accounted for in preliminary device configurations. It will contain a review of all operational phases of a marine renewable energy technology lifecycle and detail the results of an examination of other related sectors (offshore wind, Oil &Gas, Aquaculture). Transferable knowledge and methodologies from these other sectors, which have been demonstrated to be safe, efficient and cost effective, will be described.

Report on design of 2D scale models

This is part of Task 4.1. This report will describe the design of the 2D models with sufficient detail so that the model could be replicated if necessary

Specification of design and evaluation software tools

This is part of Task 2.5. This report will describe the desired functionality of the software tools that will be used to support the concept development. The required functionality will include calculation of the Evaluation Criteria defined in D2.2 and allow the design to be referenced using the configuration specifications defined in D2.3

Preliminary assessment of computational capability report

This is part of Task 3.2. This report will provide a preliminary assessment of the numerical modelling capabilities together with initial modelling results

Data management plan

This is part of Task 10.2. A report that describes the plans for data management. This will be based on the H2020 template: Data management plan v1.0 – 13.10.2016. It will include references to all of the data that is expected to be generated in the project together with plans for how it will be stored and made available to users.

Idnetification of potential technology strssors and environmental receptors of the LiftWEC technology

This deliverable is part of Task 9.1. A report will be delivered with the identification of stressors and receptors considering the technology characteristics and the natural sensitivity of potential deployment sites.

Report on synthesis of design knowledge

This is part of Task 2.6. This report will update and improve the design knowledge that will be used for the identification of the baseline configurations. All refinements to the design knowledge will be explained and associated with specific knowledge gained.

Assessment of preliminary configurations

This deliverable is linked to Tasks 7.2 and 7.3 and will describe the results of the assessment of the preliminary configuration designs of the LiftWEC concept. It will fully detail the ‘Scenario Test Cases’ that were run on the preliminary configuration designs. These will include details on the representative sites, met-ocean resource data, vessel parameter data, technician requirements and cost details. This deliverable will provide the outputs from the installation, O&M and decommissioning models for each of the preliminary configurations. A discussion on the results will be included and any potential design improvements or any operational risk areas identified will be consolidated into a series of recommendations for consideration for the baseline configuration designs.

Performance function

This deliverable is associated with Task 5.1 and involves specification of the parametric form, and outline parameters, for the performance function. This will be provided in the form of a report

Preliminary report on synthesis of design knowledge

This is part of Task 2.1. This report will provide the details of the design knowledge that supports the identification of the preliminary baseline configurations. The source of all design knowledge will be included together with a review of each piece of knowledge with reference to the LiftWEC design.

Cost database

This is part of Task 8.1. The cost database will be compiled in the form of a report. The cost database will be a critical component of the parametric cost model and the LCoE calculation tool. A successful delivery of a cost database will ensure reliable estimates of the device LCoE

Extreme event LiftWEC ULS assessment

This is part of Task 6.1 This model will provide an assessment of the ULS for the concepts assessed. A finite-element model will be delivered in addition to a report describing the methodology employed, characteristics, assumptions and discussion of pertinent elements of the study. This deliverable will ascertain whether or not the concepts can withstand any anticipated extreme loading event.

Transportation and maintenance LiftWEC ULS assessment

This is part of Task 6.2 The model developed in Task 6.1 will be further utilised to analyse loads under transportation, maintenance and decommissioning. The report will describe the loads applied and resulting stresses critically reviewing these in terms of survivability under transportation and maintenance modes. This deliverable will ascertain whether or not the concepts can withstand transportation loads and the degree to which the concepts considered are maintainable and decomissionable from a structural perspective.

Identification of evaluation criteria

This is part of Task 2.2. This report will describe the evaluation criteria that will be used to guide the selection of the baseline configurations and assess their performance and provide clear guidelines for their use by an external party. This report will also include details of the knowledge gathering workshop

Website

This is part of Task 10.1. The project website and social media accounts will be created using standard tools to minimise the required investment in development. The website will contain details of the project, links to public project deliverables and a feedback page
