The second version of the wave and tidal energy arrays design tool DTOcean has been released, offering full levelised cost of energy (LCoE) calculation for the first time.

Delivered by Irish consultancy Data Only Greater, in partnership with US Department of Energy, National Nuclear Security Administration laboratory Sandia National Laboratories, DTOcean 2.0 also adds functionality to help developers quantify risk to profitability resulting from the unique environmental conditions faced by ocean energy technologies.

Speaking about the 18-month project, Dr Mathew Topper, founder of Data Only Greater, said: “Working with Sandia, we found a number of bugs that prevented the tool from functioning correctly. I managed to fix these and, at the same time, solve some of the scientific challenges that remained from the original DTOcean project. That work has now formed the basis of a journal article, currently under review, and this new release of DTOcean.”

Bugs removed

Following the January 2017 release of the first version of the tool, which was the ultimate deliverable of the DTOcean FP7 EU 3‐year project, Sandia helped to identify bugs in the software and evaluate its effectiveness by comparing the output to wave and tidal energy reference models.

Given a set of user inputs regarding the chosen wave or tidal energy converter and array location, DTOcean can automate device layout, balance of plant, logistics procedures and lifetime array maintenance requirements.
