Tidal Turbine Assessment and Design

Xi fulfilled the role of R&D partner, working closely with the team to
ensure that the device would not suffer failures as well as optimisation of different elements of the structure.

Issue

The environment in which tidal turbines operate by nature is harsh.
The cost of deployment and removal of tidal turbines is expensive,
tide and weather windows are short. This drives manufacturers to
design systems which are both robust and require limited
maintenance. Andritz Hydro Hammerfest realised that in order to
robustly assess the dynamics of their design they could engage the
services of Xi.

Solution

Xi assisted Andritz Hydro Hammerfest through the design process for
both the HS1000 and the MK1 devices. Xi produced holistic models
of the systems during the design phases, allowing them to assess the
entire system from a dynamic perspective, specifically, fatigue and
inter-component frequency matching.

Xi's Role

Xi fulfilled the role of R&D partner, working closely with the team to
ensure that the device would not suffer failures as well as
optimisation of different elements of the structure.
Our Independent design validation provided both risk reduction and
improved elements within the design.
