DTOcean is a collaborative, international program with the ultimate goal of accelerating industrial ocean power energy generation. Together, Sandia National Laboratories and 17 European organizations developed open-source design tools for accelerating the decision making process for the design of wave and tidal energy converter arrays.
The DTOcean Software
The DTOcean software automates the design of an MHK array. The software integrates a modular set of tools that cover the full spectrum of design tasks, including: hydrodynamic performance, the electrical subsystem, moorings and foundations, and logistics for installation, operations, and maintenance. Economics (e.g., levelized cost of energy or LCOE), reliability, and environmental protection represent major themes and constraints for the design tools.
Project developers can use the software to narrow down options for MHK arrays, saving time and costs. After identifying optimal siting and design specifications using DTOcean, developers can fully design arrays using more sophisticated, but more time-consuming, design tools.
- Free, open-source design tool with intuitive framework and graphical user interface
- Can investigate a wide range of array sizes, device ratings, water depths, seabed types, and distances to shore/port/load out
- Allows users to conduct sensitivity and multivariability analysis
- Includes preloaded databases of components, logistics, and site- and device-specific data.
- Design process divided into five modules:
- Hydrodynamics: designs the layout of converters in a chosen region and calculates their power output
- Electrical Sub-Systems: designs an electrical layout for the given converter locations and calculates the electrical energy exported to shore
- Moorings and Foundations: designs the foundations, anchors, and moorings required to secure the converters at their given locations
- Installation: designs the installation plan for the energy converters and the components required to satisfy the electrical sub-system and moorings and foundations designs
- Operations and Maintenance: calculates the required maintenance actions and power losses resulting from the operation of the converters over the lifetime of the array
- Can evaluate each stage of the design, and the design as a whole, using three thematic assessments:
- Economics: produces economic indicators for the design, in particular the Levelized Cost of Energy (LCOE)
- Reliability: assesses the reliability of the components in the design over the array lifetime
- Environmental: assesses the environmental impact of each stage of the design
