WP5 - Deployment Design Tools

The activities in this work package aim at conceiving, implementing, producing and verifying a full suite of advanced design tools (TRL 5) based on open source software. These tools will cover the main functionalities of an ocean energy system: site characterisation, energy capture, energy transformation (PTO & control), energy delivery (grid issues), station keeping (moorings and foundations), and logistics & marine Operations.

Specific objectives of this work package

  • Design the ocean energy development routines and interfaces with the data model/user.
  • Develop open source software that can read from and populate data models with design groupings, datasets attributes and links.
  • Test and verify the individual tools.

Tasks to be performed

Technical requirements of the ocean energy development tools

The technical specifications of the DTOceanPlus software architecture will be detailed in order to meet the requirements described in WP2. As a result, the needs in terms of data (inputs, outputs and interaction with the assessment tools developed in WP6) will be identified. Moreover, the upgrades of the tools to be implemented will be defined. Similarly, a set of commercial tools that can be coupled with the toolset will be identified, based on their popularity among users and the technical community and the added value of coupling this software with the DTOceanPlus toolset. All the tools will have an interface with the Salome platform to facilitate the workflow between individual tools and for the integration process in WP7.

Software development and testing - alpha version

This task will involve the software implementation of new functions, interfaces and improvements previously identified. The leader of the task will coordinate the software development work in tight connection with all the developers in order to guarantee minimum quality standard of the alpha version and the fulfilment of the requirements previously identified. The following design tools will be provided:

  • Site characterisation
    The new site characterisation tool will receive as input the environmental data (bathymetry, sea weather climate, etc.) of the site and will output post-processed data to the other tools and to the user for direct visualisation. In this task, the interfaces for coupling the DTOceanPlus toolset with a suite of free-surface flow solvers will be implemented in order to take into account bathymetry effects on the resource and the add-on tools for pre-processing the environmental data, i.e. creation of scatter diagrams.
  • Energy capture at array level
    The new site characterisation tool will receive as input the environmental data (bathymetry, sea weather climate, etc.) of the site and will output post-processed data to the other tools and to the user for direct visualisation. In this task, the interfaces for coupling the DTOceanPlus toolset with a suite of free-surface flow solvers will be implemented in order to take into account bathymetry effects on the resource and the add-on tools for pre-processing the environmental data, i.e. creation of scatter diagrams.
  • Energy transformation
    This task is aimed at developing a novel tool for assessing the efficiency of different Power Take-Offs (PTOs) and control strategies, given a specific ocean energy system. The tool will allow the user to choose among the most common PTOs (hydraulic systems, air turbines, hydro turbines, direct drive mechanical system and direct drive electrical system) and control strategy to implement (e.g. passive loading control, latching control or reactive loading control). The tool will provide an estimate of efficiency as well as loading and other outputs as identified by the developers of the assessment tools in WP6.
  • Energy delivery
    This task will develop a module for designing the electrical infrastructure for an array of energy devices and deliver electrical power to the onshore distribution network. The tool will maximise the level and quality of delivered power, focusing on the transmission efficiency, voltages, frequency, flicker and overall grid compliance, as well as assessing the cost and value of flexible generation and delivery. Requirements for all key electrical infrastructure components will be defined, then the components will be selected and a design for the whole transmission system will be assembled. The DTOceanPlus energy delivery module will include the consideration of new topologies (e.g. multiple export cables), intelligent clustering of devices and improved cable routing algorithms.
  • Station keeping
    The station keeping module will support the design of the mooring and foundation subsystems. The tool will deal with the full design of gravity foundations, piles, anchors, mooring lines, mechanical design of the dynamic umbilical cable and its interaction with the other elements of the mooring system. The technical-economic approach will allow an automated design process and the fast design and selection of the best technology fitting the farm configuration.
  • Logistics and marine operations planning
    This module will produce a set of functions assisting the user in the design and the planning of all the lifecycle operations (installation, maintenance, decommissioning) and the definition of the associated logistics requirements (e.g. vessels, labour or port availability) of the ocean energy system to be deployed. This task will be carried out in very close connection with task related to production of Reliability, Availability, Maintainability and Survivability (RAMS) tools.

Verification of the code - beta version

This task will carry out the testing of the software tools in order to verify that it meets the requirements defined in WP2 and the design guidelines previously defined.
At the end of the round of testing a stable version (beta) of the tools will be available, and it will be fully documented with a technical manual and a user manual. This version will be further validated and demonstrated using real data from the first pilot experiences in WP7.
