A toolset at TRL 5 will be developed to globally assess the design of each technology, including sub-system, device or array. This is a complex but key part of the overall tool which will provide information to the developer on the suitability of a technology for commercial development, using technical and non-technical analysis to provide key metrics, including the stage gate. The final target of the toolset is to empower the developers to correctly target their efforts to technology designs that have the required KPIs, and produce data for potential investors to evaluate the technologies. The toolset will use models, methods, decision making processes and benchmarking to evaluate performance, reliability, availability, maintainability, survivability, lifetime costs and environmental and social acceptance.
Specific objectives of this work package
- Define KPIs within the main categories of evaluation criteria.
- Define requirements in terms of digital information and data to fulfil user requirements as in Work Package 2 - Refinement of User Needs.
- Develop robust, time effective and accurate algorithms for the evaluation of the assessments.
- Obtain open source software reading a generic digital model and producing quantitative assessments.
- Test and verify the individual tools.
Tasks to be performed
Technical requirements of the ocean energy assessment tools
The objective of this task is to build a stable software architecture and its needs in terms of information and data. The aim is that this framework (formats, data classes, links between code sets) is set before the development of the specific tools, aiming for the maximum functionality and impact in all the four areas defined in further tasks and a swift interaction between the WP6 code and the other work packages. The objective is to establish the following basis of the code architecture:
- the algorithm(s) which will be followed
- the scope for the alpha version and the final beta version of the assessment tools to be delivered
- the expected data models required and their expected requirements for the assessments
- the origin of the data for the assessments
- the minimum level of granularity of the data required for running the assessment tools
- an estimation on how each assessment would tackle with the uncertainty in the data
- based on WP2 definition of the user needs and thresholds of acceptability for the assessments.
Software development and testing - alpha version
This task will be performed in parallel with other tasks of this work package, using an agile software development methodology. The final target of this task and the following ones is to achieve an “alpha” version for each of the assessment tools with a common structure and usability, fully integrated with the design tools developed in WP5. The following design tools will be provided:
- System performance and energy yield
A new tool will be released to provide information to the user on the performance level of each subsystem, device or array. This tool will be able to compute the Key Performance Indicators (KPIs) needed for this evaluation. It will also benchmark a technology against a wide referenced set of technologies consistently with the work done in WP4.
- Reliability, availability, maintainability and survivability system
The objective of this task is to produce a Reliability, Availability, Maintainability and Survivability (RAMS) tool. Metrics linked to the reliability of the system will be estimated based on the available failure rates previously collected and probabilistic models for failure of structural components. Metrics linked to the availability will be estimated based on reliability data, site specific weather data, maintenance strategies and maintainability of the system components coordinated with logistics and marine operations planning.
- System lifetime costs
A System Lifetime Costs tool will be developed by computing several metrics on costs at different levels of aggregation or breakdown and benchmarking them according to reference values for the industry consistently with WP4. The objective is to allow the user to obtain good estimates of the costs of the technology but also understand if the technologies are competitive and financially viable in its life cycle.
- System environmental and social acceptance
An environmental and social acceptance tool including environmental and socio-economic impact assessment modules will be produced. The accuracy of the existing environmental impact assessment will be improved thanks to the building of a georeferenced database of species and local impacts and to the links with WP5 tools allowing the estimation of impacts based on the technology.
Verification of the code - beta version
This task aims to deliver the final version (beta) of the four assessment tools. EDF will set a thorough verification of the code, as well as milestones and phases for the debugging. The objective is to verify that the assessment toolset meets the requirements defined in WP2 and the design guidelines previously defined.
