Client: Andritz Hydro Hammerfest
Project: Blade design optimisation for Meygen project

“We have appointed Digital Engineering to support our turbine blade team with the setup and introduction of an optimisation algorithm for our tidal turbine blades, integrating into the AHH tool chain. Digital Engineering has a broad knowledge of using and applying state-of-the-art analysis technology and has brought Hammerfest’s in-house knowledge to the next level.”

Michael Betschart, Technical Manager at Andritz-Hydro Hammerfest

Andritz Hydro Hammerfest is a tidal turbine developer based in Glasgow. The client commissioned Digital Engineering to optimise its HS1000 turbine blades in order to meet performance requirements for the Meygen project in the Pentland Firth in Scotland. It is the largest planned tidal development project in the world and will be made up of 269 tidal turbines, with a total installed capacity of 398 MWh, which is enough to power 175,000 Scottish homes.

We used an innovative technique to parameterise the blade geometry so that it could be assessed and tested in a cost-effective manner. Thousands of potential designs were tested using BEM/CFD models against several performance targets whilst also ensuring that they met manufacturing, structural and control system design requirements.

As a result of the work, the performance of the original prototype blade was improved by more than 20%. In addition, the integrated design approach we applied delivered final blade designs that were ready for manufacturing. This helped to reduce the overall time of the engineering design phase.
